Shield machine: "iron earthworm" for digging subway tunnel

Writing/Photo courtesy of Liu Zhirong

You can’t always stay at home, but you have to travel, or commute to work, or go on business trips, sightseeing, and travel can’t be separated from subways, railways and highways. When you take subways, trains and highways, have you ever wondered: How are those tunnels dug through them?

Early tunnel excavation was manual plus blasting.

In the past, the way of tunnel excavation was manual excavation and blasting. For soil layer and gravel geology, manual excavation was used, and tools such as pickaxe and shovel were used to excavate the tunnel face. As far as rock geology is concerned, pickaxes and shovels can’t be dug, so it is necessary to use explosives to blast rocks at the tunnel face, and then transport the gravel out of the tunnel.

"Face" is a civil construction term, which refers to the excavation face that keeps advancing during tunnel construction.

As far as subway tunnels are concerned, in the past, the "open excavation and landfill method" technology was mostly adopted, that is, the street was destroyed first, and a ditch was dug by uncovering the cover, and then the tunnel wall was poured in the ditch. After the tunnel was built, it was buried and compacted with earthwork, and the street was repaired again. In the early days of Chinese mainland, the subway tunnel was excavated by "open excavation and landfill method", and later the "shield machine excavation method" was adopted. Shield machine was used to dig tunnels in the construction of Guangzhou’s first subway line (Line 1).

In the past hundred years, shield machines have gradually become popular in tunnel excavation. At present, shield machines are basically used in long tunnel excavation.

Britain used a shield machine to dig tunnels in 1825.

"Shield machine" is a name in China, generally known as "tunnel boring machine" (TBM) internationally, and "mole" in civil engineering jargon, because it digs holes underground like a mole.

In 1825, Britain used a shield machine when digging the Thames Tunnel. This shield machine was invented by Sir Mark issam Bald brunell, a French-born British engineer, and he applied for a patent for the shield machine. The Thames Tunnel is 396 meters long and passes through the Thames River in London.

In 1845, the international railway from France to Italy was opened. This railway ran across the Alps, and it was necessary to dig the Freres Tunnel at an altitude of 1,123 meters. This tunnel was 14 kilometers long, which was the longest tunnel in the world at that time. The tunnel ran through the Freres Peak at an altitude of 2,932 meters, that is to say, the maximum thickness of the rock above the tunnel was 1,809 meters.

In order to build this tunnel, Henry Joseph Mauss invented the "mountain cutting machine", which was manufactured in an arsenal near Turin, Italy in 1846. The "mountain cutter" looks like a locomotive, with more than 100 vibrating drill bits in front, which are used to smash the rocks on the face. "Mountain cutting machine" already has some functions of modern shield machine.

In 1853, ebenezer Talbot, an American, applied for the patent of shield machine, and the patent name was "Tunnel Boring Machine".

In 1870, john D bruton, an Englishman, developed and manufactured a shield machine with cutter head, which is very close to the shield machine widely used now.

In 1875, the French National Assembly passed a bill to build the English Channel Tunnel, and the British shield machine was selected for excavation. From June 1882 to March 1883, the shield machine excavated 1882 meters on the British side; Alexander Lavalle, a French contractor who built the Suez Canal, used a shield machine to dig 1,669 meters on the French side. Practice has proved that the efficiency of tunneling with shield machine is very high. However, the project was terminated in 1883 because France was later worried that Britain would use the English Channel Tunnel to attack France.

The success of shield machine in the English Channel Tunnel has inspired many civil engineers. In 1883, Britain used a shield machine to dig the tunnel under the Mersey River from Biegenheit to Liverpool, with a diameter of 2.1 meters and a length of 2 kilometers.

In the 20th century, people constantly improved the shield machine. Nowadays, all kinds of shield machines are constantly running in tunnel projects all over the world every day.

How does the shield machine dig the tunnel?

It is easier to understand the working principle of shield machine from its international common name "tunnel drilling rig": it is a big drilling rig that drills a hole in the ground or mountain.

Shield machine can be regarded as the largest construction machinery in civil engineering, with a large diameter of 178 meters and a length of more than 100 meters. The front of the shield machine is a huge cutter head with cutter head array. When driving, the cutter head rotates to cut the earth and stone on the tunnel face, and the muck flows into the muck bin from the gap of the cutter head, which is conveyed to the belt conveyor by the screw machine, and then transferred to another longer belt conveyor to transport it to the muck disposal site outside the tunnel, or transported to the tunnel by the track muck truck.

Readers with a little common sense should understand that if there is no thrust behind the cutter head, it is impossible to cut the earth and stone on the face. So, how to give the cutter head thrust?

This thrust comes from the hydraulic jack of the shield machine. If the tunnel is excavated on hard rock, two huge hydraulic jacks on the shield machine lean backward against the rock walls on both sides of the excavated tunnel and push the cutter head forward to cut the tunnel face.

If the tunnel is dug in the soft geological layer, the above method cannot be used, because the hydraulic jack will sink into the soft tunnel wall and cannot provide thrust. At this time, it is necessary to use another method to make several small hydraulic jacks push against the lining segment installed at the back at the same time to provide thrust for the cutter head horizontally forward, which is also a common shield method in subway tunnels at present.

The lining segment is the reinforced concrete precast member on the tunnel surface that we can see with our naked eyes in the tunnel. These segments are made in the ground reinforced concrete precast yard. After the segment is transported into the tunnel mouth, there is no need for manual intervention, and the transportation to installation is completely automatic.

The width of the lining segment should match the distance that the hydraulic jack advances each time, that is to say, the width of the segment is as many centimeters as the hydraulic jack advances each time. When the hydraulic jack is pushed to the end, the cutterhead stops rotating to cut the tunnel face, and segments are assembled around the tunnel in the shield section of the shield machine. The segment assembling machine on the shield machine is as dexterous as a human hand, movable, rotatable and retractable, which can assemble segments in place steadily and safely with accuracy of millimeter level.

When assembling a segment, several hydraulic jacks responsible for jacking the segment will contract, leaving a certain space for assembling the segment. After the segments are assembled in place, the hydraulic jack will stretch out and gently hold it, and so on until all segments in this circle are assembled in place. At this point, all the hydraulic jacks began to pressurize evenly, and together with the newly assembled segment, the cutter head was pushed forward by the reaction force to continue cutting the working face and move forward.

During the construction of the shield machine, the cutterhead cuts the tunnel face and assembles segments alternately, and the whole shield machine moves forward step by step under the push of the hydraulic jack until the tunnel is dug through. If the geology is soft, tens of meters can be excavated every day; If you encounter hard rocks, you can only dig dozens of centimeters every day.

The gap between the lining segment and the tunnel wall should be filled with mortar to reinforce the segment, maintain the stability of the whole lining and prevent water from leaking into the tunnel.

The series of complicated processes mentioned above are all completed automatically by the shield machine. There is a central control room in the shield machine, and all key parts of the shield machine have sensors, which transmit the collected data to the central control room. Operators can know the working situation of the shield machine through various data displayed on the display and intervene when necessary.

The cutter head on the cutter head should be maintained and replaced frequently. There is also a sensor on the cutter head. When the temperature of the cutter head rises to a certain value, it will send an alarm signal to the central control room.

How does the shield machine turn in the tunnel?

After reading this, some readers may ask, can the shield machine turn in the tunnel?

Of course you can. Most urban subway tunnels are excavated under the streets, and the tunnels are designed along the streets, with constant turns and "jumping up and down" according to the underground conditions. Highway and railway tunnels should also be selected according to landform, geology and hydrology, which also requires the shield machine to turn 360 degrees.

The turning of shield machine is realized by changing the cutting direction of cutter head with lining segment. Where a turn is needed, the width of each ring of lining segment is different. If turning to the left, the width of the right segment is designed to be wider than that of the left segment according to the turning radius. In this way, the hydraulic jack on the right will tilt the cutter head to the left to realize the left turning. If turning right, the width of the left segment is designed to be wider than that of the right segment according to the turning radius, so that the hydraulic jack on the left will tilt the cutter head to the right and realize the right turn. The steering principle of "jumping up and down" is the same as above.

At present, the largest shield machine in the world has a diameter of 17.5 meters.  

On September 15th, 2006, the Niagara Tunnel, which was used for water diversion irrigation in Canada, was drilled. The tunnel was 10.2km long and passed 140m underground in Niagara Falls, Ontario, Canada. The shield machine used was "Big Becky" made by Robbins Company of the United States, with a diameter of 14.4m. The cutter head was driven by 15 motors with a power of 4.7 million watts (6,375 horsepower), which was the largest shield machine in the world at that time. The reason why tunnels should be dug in such a deep underground is to prevent shield construction from affecting ground buildings.

In 2011, the 5030-meter-long Spavo Tunnel near Florence, Italy was drilled. The rock shield machine used was Martina produced by Herrick Company of Germany. The shield has a diameter of 15.62 meters, a length of 130 meters, a weight of 4,500 tons, a cross-section of 192 square meters, a total power of 18 megawatts and a thrust of 40,000 tons. Herrick also designed a shield machine with a diameter of 19.25 meters, but it has not yet been built.

Bertha, a shield machine made by Hitachi Shipbuilding Co., Ltd. in Japan in 2012, has a diameter of 17.5 meters, a length of 110 meters and a weight of 7,000 tons. The cutter head has 260 cutter heads. This shield machine was ordered by the Washington State Transportation Bureau of the United States and used to replace the tunnel excavation of Alaska Viaduct on Highway 99 (the upper and lower lanes of the tunnel), which is by far the largest shield machine in the world.

Advantages and disadvantages of shield tunneling

There are many advantages in tunneling with shield machine. It is not affected by ground factors and can be constructed all day; It also does not destroy the ground buildings, cultural relics and natural environment, and belongs to ecological and environmental protection construction; Because the excavation, muck discharge and lining segment are all automated, a lot of labor is saved and the accident risk is reduced.

The main disadvantage of tunneling with shield machine is that the initial investment cost is too high. Most shield machines are customized according to tunnel design drawings, with long construction preparation period, high maintenance cost, and low economic benefits of tunneling short tunnels. Generally speaking, the tunnel length is more than 1 km, which has economic benefits.

Finally, the shield machine can not only dig circular tunnels, but also be designed to dig tunnels with arbitrary cross sections, such as rectangular tunnels and elliptical tunnels. People also use shield machines to dig water pipelines, sewage and drainage pipelines, and even power pipelines.

Scientists in China have observed for the first time that Sichuan golden monkey has a "wet nurse": reducing the death rate in severe winter.

A starving baby, if the mother has other conditions such as insufficient milk, will usually be fed by other lactating mothers instead. This kind of behavior in humans is popularly called "wet nurse feeding", and scientifically it is defined as allomaternalbreastfeeding.

In fact, scientists have observed similar phenomena not only in humans, but also in rodents and primates. A recent study by scientists in China has further expanded the scope: the research team led by Zuo Fu, a professor at the School of Life Science and Technology of Central South University of Forestry and Technology, and Li Ming, head of the primate ecology research group of the Institute of Zoology, Chinese Academy of Sciences, obtained the evidence of the old world monkey’s maternal lactation for the first time. The research results were published on February 21st, Beijing time, in Science Progress, a sub-magazine of Science.

Breastfeeding behavior of Sichuan golden monkey. The pictures in this paper are provided by the research team.

In an interview with The Paper reporter (www.thepaper.cn), Zuo Fu said, "This is the first time to report that regular partheno-lactation exists in Old World monkeys, which has expanded the distribution of partheno-lactation in primates and made it appear in different groups such as proto-monkeys, New World monkeys, Old World monkeys and even humans."

Higher primates, that is, anthropophagus, include New World monkeys distributed in South America and Old World monkeys distributed in Eurasia (Old World). Previously, there was no report about the maternal lactation behavior of Old World monkeys. According to Zuo Fu, the research team started this new research in 2012 and observed it continuously for five years. The research was carried out in Dalongtan Research Base of Shennongjia National Park in Hubei Province.

The research base has a group of about 90 golden snub-nosed monkey. Sichuan golden monkey is endemic to China, with a golden fur. They are distributed in the forests at the junction of Hubei, Sichuan, Shaanxi and Gansu, and distributed in Minshan, Qionglai, Daxueshan, Xiaoliangshan, Qinling, Shennongjia and the northern slope of Motianling.

"We began to study the monkey group in 2006, and the researchers were able to identify all individuals over 3 years old in the group." Zuo Fu said that the birth of Sichuan golden monkey is basically concentrated in the period from March to May every year. Because the coat color and body shape of baby monkeys are similar, it is not easy to identify them, so there is no concern about whether there is maternal breastfeeding at first. "Until the spring of 2011, after accidentally finding a female monkey feeding two baby monkeys at the same time, the research team carefully observed the breastfeeding behavior of Sichuan golden monkeys in the group and found that the breastfeeding behavior of different mothers was more common."

This latest paper shows that in the field observation conducted by Zuo Fu et al. for five years in a row and after five farrowing seasons, 40 (87%) of 46 baby monkeys of Sichuan golden monkey were breast-fed by one or more non-mother monkeys, and 22 (48%) of 46 baby monkeys were breast-fed by at least two other mothers. This behavior of maternal breastfeeding mainly occurs in the first three months after the baby monkey is born.

The research team also found that 6 of the 46 baby monkeys did not receive maternal breastfeeding at all, and 4 of them died in the cold winter. In comparison, among the 40 baby monkeys that were breast-fed by at least one non-mother monkey, a total of 6 eventually died, and the mortality rate was greatly reduced.

It is worth noting that Sichuan golden monkey generally lives in temperate forests with high altitude, and it is extremely cold in winter for five months, and the food supply also has strong seasonal changes. Partheno-breastfeeding behavior may help baby monkeys fight against unfavorable living environment.

Zuo Fu said, "The behavior of maternal breastfeeding may provide energy support for the rapid development of baby monkeys after birth, so that the baby monkeys can feed in advance to achieve a good development state before the severe winter, and can successfully survive the winter of extreme low temperature and food shortage. This behavior may also provide energy support for the rapid development of the brain, which makes the brain capacity of golden monkeys relatively large."

Generally speaking, the behavior of maternal breastfeeding only occurs within three months or less after the baby monkey is born, and it almost stops when the baby monkey begins to eat natural food.

In addition, the research team also found that the maternal breastfeeding behavior in Sichuan golden monkey still follows certain principles. Baby monkeys can not suck milk in all non-maternal monkeys: the maternal breastfeeding behavior of Sichuan golden monkey only occurs between females who are related or breastfeeding each other.

It is mentioned in the paper that kinship-usually the "grandmother" or "aunt" of baby monkeys, or reciprocity plays an important role in maternal breastfeeding. About 90% female monkeys (25 out of 28) will breast-feed the cubs of other female monkeys who have breast-fed their own baby monkeys in the current or next year, which is similar to "reward".

Zuo Fu believes that the maternal breastfeeding behavior occurs between females who are related or cooperate with each other, and the mother will allow other females to contact the baby monkeys in the early stage of development, which is necessary for the infant-mother-maternal care relationship in the early stage of human evolution, so this study also provides a new perspective for understanding human evolution.

Russian woman’s sudden death in China train continued: biological samples have been sent to Moscow.

    Biological samples collected from the dead China woman’s body on the "Blagoveshchensk-Moscow" train, as well as laboratory analysis data in the carriage, have arrived in Moscow.


    Onishchenko, director of the Russian Consumer Rights Protection and Public Welfare Supervision Bureau and chief epidemic prevention physician of the Russian Federation, made the above statement on Thursday, according to the Russian new network news.


    He said that the inspection will be conducted simultaneously in two specialized laboratories of the Ministry of Health and one laboratory of the Ministry of National Defense.


    He pointed out that due to the death of a woman in China on the train, the health department started the traditional epidemic prevention emergency mechanism.


    On the morning of April 15th, a 24-year-old Russian woman died unexpectedly while riding a long-distance train from the Russian Far East city of Blagoveshchensk to Moscow. Fifty-one Russian migrant workers and two Russian train attendants were sent to the local infectious disease hospital for isolation observation when the train stopped at the Kirov station. It is reported that the final destination of these China migrant workers is Kaluga.


    This incident has attracted great attention from the Ministry of Foreign Affairs of China. On April 16th, Foreign Ministry spokeswoman Jiang Yu said at a regular press conference that the Ministry of Foreign Affairs attached great importance to the situation that "a Russian woman may have died of pneumonia while taking a train in China".

Rumors of College Entrance Examination and Precautions —— Exam Edition

  Every year, on the eve of the college entrance examination, there will always be some old news and news of the college entrance examination that have been repeatedly proved to be false on the Internet, misleading candidates and the public. To this end, the education department, the online information department and the public security organs have combed and summarized the fake news and false information of the college entrance examination with the highest frequency of "cold rice and hot speculation" over the years, and reminded the majority of netizens that behind these rumors are scams carefully designed by unscrupulous merchants, websites and even recidivists. The three departments specially remind candidates and parents to distinguish between rumors and beware of being deceived. I hope that all websites will not provide a platform for rumors, and I hope that netizens will not believe or spread rumors.

  First, spend money to buy college entrance examination questions and answers.

  Every year, criminals peddle so-called "true college entrance examination questions" and "top secret answers" on phishing websites, flaunting seductive information such as "extremely high accuracy" and "refund for breach of contract", and asking users to pay in advance in the name of "advance deposit". There are also those who claim that they can pay "gunmen" to take the test. Some criminals send viruses to users’ computers or mobile phones in the name of transmitting "sample test papers" to obtain user information.

  Case: On the eve of the college entrance examination in 2018, the police in Hohhot cracked a case of selling so-called "college entrance examination questions". It is reported that under the name of QQ, some people have established a large number of QQ groups such as "2018 college entrance examination internal questions", hyped up the sale of college entrance examination original questions at the price of each set of 300 yuan, and ensured that "half of the real questions in each subject" and "get the real questions in the college entrance examination at 6 am on June 6, and send them out on time at 5 pm". After grasping conclusive evidence, the police handling the case arrested the suspect Dai Moumou. After the trial, the suspect Dai Moumou confessed to his fraud. Dai confessed that the so-called college entrance examination questions are actually a set of simulated college entrance examination papers purchased online at the price of each set of 200 yuan.

  Reminder: The college entrance examination questions belong to the national top secret materials, and their storage and transportation have strict management measures. All personnel who come into contact with the examination papers are subject to closed management. The majority of candidates and parents should not be lucky, and do not believe that the so-called college entrance examination questions and answers are obtained in advance. Buying so-called "true college entrance examination questions" and "top secret answers" online are all false information released by scammers. It is illegal to buy classified materials, so don’t try.

  The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "organize cheating", "provide cheating equipment or other help for others to commit the crime mentioned in the preceding paragraph", "illegally sell or provide the test questions and answers specified in the first paragraph to others for the purpose of cheating in the exam" and "replace others or let others take the test specified in the first paragraph instead of themselves".

  Second, look for candidates who have lost their admission tickets

  Every year, on the day of the college entrance examination, the information lost by the candidates’ admission ticket will be circulated on the Internet. After seeing it, the majority of netizens were anxious for the candidates and quickly forwarded it in the group and friends circle, forming a public opinion with a large influence in a short time. After the incident, the education department quickly verified that some candidates did not lose their documents at all, and some information did not match completely, which can be said to be basically false information. The public security organs also confirmed that the left mobile phone numbers are generally fraudulent calls. Fraudsters make up stories to cheat social kindness. If a good-hearted person calls back according to the phone number and operates according to the phone prompt tone, he may fall into the trap of charging.

  Case: In 2016, "My friend picked up an admission ticket, so please inform me if you know it: name: Bai Yaqian, test center: No.1 Middle School, examination room: 013, seat number: 11, admission ticket number: 204101311, contact number: 159 * * * 8941, spread, spread, don’t delay the children’s college entrance examination. Help others leave a lingering fragrance! " This is a false news that has been circulating on the Internet for many years. In 2017, there were many lost information about the admission ticket, and those who lost the admission ticket were Liu Mingwei, Yang Leilei, Sun Chao and Dang Xilong. In 2018, "Liu Mingxi" and "Liu Mingting" students lost the admission ticket again, and the content completely copied the routines of previous years.

  Reminder: After seeing similar information, it is recommended to contact the report phone number published by the candidate’s middle school or provincial admissions examination institutions for confirmation. It is not recommended to forward it without verification, or to call the contact phone number left after the information.

  Third, the marking teacher only cares about the progress, regardless of right or wrong.

  Every year after the end of the college entrance examination, before and after the results are announced, there are always people on the internet who speculate that the marking work of the college entrance examination in a certain place is extremely serious, and the marking teachers even mark it indiscriminately, regardless of right or wrong. Facts have proved that people who post these posts are often out of curiosity, and some candidates and parents who have a large or unsatisfactory gap in college entrance examination results think that there is something wrong with marking and arbitrarily guess the information.

  Case: In a well-known forum, there was a post "The college entrance examination marking teacher risked his life to expose the inside story, so the future of students was delayed". The poster claimed to have participated in marking the college entrance examination in a province, and the marking teacher only wanted to catch up with the progress, or ignored the confusion, or "approved the composition in one minute", disregard for human life. This post is related to the content of the college entrance examination, attracting attention and quickly becoming a hot spot, which is reprinted in major forums. Some netizens shouted, "No wonder their scores in the college entrance examination were lower than expected, so that’s how they were cheated." The education department and the public security organs quickly checked people. According to the poster, it was just for fun, to attract netizens’ attention and improve their popularity. They didn’t participate in the marking of the college entrance examination themselves. Some of them listened to rumors and made their own interpretations. They realized the seriousness of the matter and deleted the content themselves and apologized to the society.

  Reminder: marking the college entrance examination papers is a very serious job. At present, the popular "online marking" embodies fairness and justice from system design to actual operation. For example, most provincial marking teachers have to pass the "three levels", that is, the qualification level. All middle school teachers who participate in marking work must be backbone teachers with the title of middle school education level or above. The head of the department and the head of the topic are university teachers with high academic level, rich teaching experience and the title of associate professor or above. Those who do not meet the above qualifications are not allowed to participate in marking; Training pass, all marking teachers must be trained in marking standards, master the marking standards and requirements, and those who have not participated in the marking standards training are not allowed to participate in marking work; All marking teachers must pass the examination. Before marking, each marking teacher must pass at least 7 of the 10 assessment papers. In the marking process, irregular assessments are also made. If the two assessments fail, no formal marking is allowed. Before the formal marking, a trial marking should be conducted, and scientific and reasonable scoring rules should be formulated according to the scoring reference and the actual situation of the candidates’ answers, and the formal marking should be strictly implemented in accordance with the scoring rules. The system of "one person evaluates one question" is generally implemented to ensure the quality of marking. For Chinese and English compositions, the system of "double evaluation" by different teachers is adopted. If the "double evaluation" exceeds a certain error, it will be submitted to the third teacher for "three evaluation" to ensure the accuracy and effectiveness of the evaluation. In addition, there are strict marking quality monitoring procedures to check, review and correct the marking quality of the marking staff throughout the process.Supervise and correct the phenomenon that the grading teacher may have different understanding of leniency and strictness in marking.

  Fourth, big data volunteers, charging sky-high consulting fees.

  On the eve of volunteering for the college entrance examination every year, there are always intermediaries or websites claiming to master internal big data. Local education examination institutes have made it clear that they have not cooperated with any social organizations or enterprises. According to the requirements of the Ministry of Education for information disclosure, the examination institutes have made public the enrollment plan, admission results and other data, and issued volunteer reference materials to candidates for research and reporting before applying for volunteers. The so-called "internal big data" of merchants is purely a rumor, which is nothing more than a marketing slogan. The accuracy of its data needs to be scrutinized, and there are some uncertain factors in voluntary reporting, such as the performance of candidates in this college entrance examination will affect the changes in their scores, and other candidates’ voluntary reporting.

  Case: An education and training institution advertises on its website, such as "Fill in the volunteers accurately" and "Don’t waste a penny". Candidates can buy VIP cards with different denominations, such as 20,000 yuan and 10,000 yuan, and enjoy one-on-one "accurate" guidance. After the college entrance examination, the reporter interviewed the candidates and parents who bought VIP cards. The candidates and parents generally reported that the volunteer guidance provided by the company was not professional enough, and some data were inaccurate. However, the admission data of the past three years, the open interpretation of volunteering skills and the close attention to the admission dynamic information of the examination institute issued by the education department are more accurate and practical.

  Reminder: Parents and classmates are advised to be cautious and vigilant when reporting these volunteer apps and advertisements.

  Five, you can spend money to change the college entrance examination results.

  Every year, after the college entrance examination, candidates and parents are introduced by acquaintances or learned on the Internet, so that they can get to know the experts who can enter the high-level recruitment system through hackers, modify the college entrance examination results, and ask for high-priced "service fees" at the same time, so that students can get satisfactory results.

  Case: After the end of the college entrance examination in 2015, Qinhuai police found that there were fraud cases in the area where the score was changed as bait. Ms. Zhang and Mr. Liu, who live in Qinhuai District, were cheated out of nearly 10,000 yuan. After being detected by the police, the suspect Zhang confessed that he posted information as a "hacker" on the Internet, claiming that he could modify the scores of college entrance examinations and college exams, and asked the victims for "service fees" ranging from thousands to tens of thousands of yuan. People have been fooled in recent years.

  Reminder: Online posts claiming to be able to modify college entrance examination scores are pure scams. The so-called hacker intrusion modification score is not technically feasible. Because the online marking of college entrance examination is not on the internet, but on the intranet, there is no possibility of external hacking. Before the candidates’ scores are released, the original data are archived and backed up in different places. After being released through the network, the examination institute will monitor and match the online information, and the websites will set up a strict anti-hacker virus attack system.

  Ministry of Commerce spokesman answered questions on Dutch semiconductor export control.

  According to the website of the Ministry of Commerce, the spokesman of the Ministry of Commerce answered questions on the export control of semiconductors in the Netherlands. China has noticed relevant reports. In recent months, China and the Netherlands have conducted multi-level and multi-frequency communication and consultation on semiconductor export control. However, the Dutch side finally managed the relevant semiconductor equipment, and China is dissatisfied with this. In recent years, in order to maintain its global hegemony, the United States has constantly generalized the concept of national security, abused export control measures, and even at the expense of its allies’ interests, coerced other countries to suppress and contain semiconductors in China, artificially promoting industrial decoupling and chain breaking, seriously damaging the development of the global semiconductor industry. China firmly opposes this.

  Once again, the EU failed to reach an agreement on power market reform.

  European Union countries failed to reach an agreement on European electricity market reform again on Friday, and diplomatic sources said that countries still have differences on potential new state-aided power plants. Twenty-seven EU countries are seeking to reach a common position on the reform of the EU electricity market plan, but some countries, including Germany and France, have been difficult to reach an agreement on such elements as the state aid rules for power plants. EU diplomats said. Some people complained that they didn’t have enough time to analyze the document, which was sent to countries by Sweden, which currently holds the rotating presidency of the European Union, on Thursday night. Now, the responsibility for finalizing the agreement will be transferred to Spain, which will take over the EU presidency from July until the end of the year. The planned electricity market reform aims to make the price of electricity in Europe more stable, and avoid repeating the situation that the soaring price of natural gas caused consumers to face high bills during the energy crisis last year. However, whether countries can subsidize existing power plants by signing new fixed-price electricity contracts with governments has caused great controversy.

Quality car selection: Can BMW Brilliance i5 stand out in the market?

  On January 25th, the eighth generation BMW 5 Series was officially launched. As the mainstay of BMW brand, BMW 5 Series can meet users’ expectations for mid-to high-end luxury cars every time it is replaced. However, what is even more attractive is the BMW Brilliance i5 model which is listed together. As a pure electric version of BMW Brilliance 5 Series, it gives consumers more "green brand" choices while continuing the product strength of fuel version. So can the new car stand out in the market? This issue of "Quality Car Selection" will answer for you.

  I. Basic Information and Product Highlights

  BMW Brilliance i5, BMW Brilliance 5 Series and BMW Brilliance i3 are all built on the platform of BMW CLAR, and provide "luxury suit" and "M sports suit". It is worth mentioning that the BMW i5 (imported) car series has also listed an xDrive M60 model, with a price of 639,900 yuan, and friends with sufficient budget can consider it as appropriate.

  For luxury brand models, consumers often pay attention to the individualization and differentiation of products and are willing to pay for products that meet their own needs and preferences. BMW Brilliance i5 provides domestic consumers with more in-depth and all-round customized choices, including car paint color, wheel style, seat material and interior trim strips.

  In addition, the interior style and intelligence of BMW Brilliance i5 follow the top level of BMW 7 Series. Integrated suspended curved screen, embracing interactive light band and bright crystal ornaments complement each other in the front row, outlining a rich visual experience. At the same time, the BMW iDrive 8.5 version of the car machine system has the strength to compete with the new car-making forces in intelligent interaction.

  It is worth mentioning that the BMW i5 is equipped with the same 31.3-inch 8K resolution OLED screen as the BMW 7 Series, which can support the online audio-visual entertainment function internally, and can also adjust the screen distance, tilt angle and screen ratio to achieve the best viewing effect.

  Second, product competitiveness analysis

  Judging from the pure electric medium and large car market, Beijing Benz EQE is undoubtedly the direct competitor of BMW Brilliance i5, and the Audi brand has not electrified the "Audi A6L" car series, so we chose Weilai ET7, which focuses on the high-end market, for comparison.

  From the price point of view, the price of BMW Brilliance i5 top model has certain advantages, but the starting price is the lowest of Weilai ET7, and it also supports the sales of car/electricity separation scheme. In terms of the number of models, BMW Brilliance i5 offers four models to choose from, which is more than the three models of Beijing Benz EQE and Weilai ET7, so consumers have more choices.

  Specific to the level of vehicle configuration, we selected the models with similar prices as possible. By comparison, BMW Brilliance i5 has little advantage over the other two models. First of all, BMW Brilliance i5 is comparable to Beijing Benz EQE in configuration, but the CLTC pure electric cruising range of Beijing Benz EQE model is even more outstanding, reaching the level of 700km+. Secondly, Weilai ET7 can be described as rolling BMW Brilliance i5 in all directions. It is not only equipped with dual motors, but also has a faster acceleration of 100 kilometers. Moreover, CLTC has a longer pure electric cruising range, not to mention the configuration. Independent brands have always been more kind than traditional luxury brands.

  Third, product quality & service trend analysis

  As a brand-new model, will BMW Brilliance i5 have hidden dangers of quality problems? In this regard, we will start with the failure problems of BMW Brilliance i3 model in the past year, and preliminarily predict the development trend of new car quality problems in the future by comparing the failure problems. As BMW Brilliance i5 and BMW Brilliance i3 are both built on the CLAR platform, they are deeply related and can be used as reference.

  By screening the complaint data of BMW Brilliance i3 model in the past year, it can be found that the number of complaints about "battery cooling system failure" is relatively high. As BMW Brilliance i5 and BMW Brilliance i3 both use ternary lithium batteries from Contemporary Amperex Technology Co., Limited, and the battery cooling mode is liquid cooling, the above problems may still occur. However, the actual situation remains to be determined after it has been put on the market for some time.

  With the continuous development of China’s automobile market, the level of brand pre-sales/after-sales service and the quality of purchase experience have gradually become an important factor affecting consumers’ final purchase. Therefore, based on the big data of car quality network, we will analyze the common service problems of brands in the past year to provide more objective reference for consumers to buy models.

  From the point of view of service complaints, "inconsistent with publicity" has become a service problem in which car owners complain more about BMW Brilliance brand. Through further analysis, we can know that this kind of service problem comes from BMW Brilliance X3 and BMW Brilliance 5 Series.

  In terms of measuring the after-sales service reputation of new cars, we will analyze the response of enterprises to complaints from car owners, and relatively objectively predict the future after-sales service reputation of new cars. According to the data of Chezhi. com, the response rate of BMW Brilliance brand complaints in the past year was 99.9%, which was at the upstream level among luxury brands in the same period. It can be seen that manufacturers attach great importance to the demands of car owners.

  Four, after-sales service policy and network distribution

  In terms of after-sales service policy, the warranty of the 2024 BMW Brilliance i5 vehicle is three years or 100,000 kilometers.

  After the vehicle is purchased, it is bound to involve the daily maintenance of the vehicle. At this time, the number and distribution of brand dealer stores are very important, and even have a certain impact on whether consumers buy the brand model. According to the statistics of Chezhi. com, BMW Brilliance currently has 723 dealer stores in China, covering 31 provinces, autonomous regions and municipalities directly under the Central Government, with a relatively large number of dealers in Zhejiang, Guangdong and Jiangsu provinces.

  Summary:

  As the wave of electrification intensified, traditional luxury car companies began to exert their strength. The arrival of BMW Brilliance i5 not only fills the family "I" series product matrix, but also explains to people what is the charm of electric luxury. However, because the domestic electric vehicle market is too involuted, BMW Brilliance i5 does not have much advantage in price and configuration. If the price can be lowered like BMW Brilliance i3 in the future, it will surely be more competitive at that time.

Putin intensively responded to hot issues: Russia opposes war and chaos on the Korean Peninsula.

       CCTV News:On the 19th local time, an annual meeting of Valdai International Debate Club was held in the southern Russian city of Sochi. The reason why it has attracted much attention is that the current international focus events and issues will be discussed in previous debates, and Russian President Vladimir Putin has always participated. At this year’s annual meeting, his position on the current Russian-American relations and the situation on the Korean Peninsula triggered a heated discussion in the media.

       [Russia-US relations] The US frequently accuses Russia of violating Intermediate-Range Nuclear Forces Treaty.

       Recently, the decline of Russia-US relations and the escalation of the game in various fields have attracted the attention of the international community. At the debate held in Sochi, how Russia and the United States will develop in the future and how Russia will respond to the new round of US sanctions against Russia will undoubtedly become an unavoidable issue. It is particularly worth mentioning that not long ago, the US government accused Russia of violating Intermediate-Range Nuclear Forces Treaty’s remarks.

       The so-called Intermediate-Range Nuclear Forces Treaty, the full name of which is the Treaty between the Soviet Union and the United States on the Elimination of Intermediate-range and Short-range Missiles between the Two Countries, was signed in December 1987 and took effect the following year. Intermediate-Range Nuclear Forces Treaty stipulates that the Soviet Union and the United States will completely destroy and completely ban short-and medium-range missiles with a range of 500 km to 1,000 km and medium-range missiles with a range of 1,000 km to 5,000 km. Intermediate-Range Nuclear Forces Treaty will have just signed the 30th anniversary by the end of this year, but the United States has frequently accused Russia of violating the provisions of the treaty. In this regard, Russian Putin stressed that Russia has been seriously implementing the Intermediate-Range Nuclear Forces Treaty and will continue to implement it; However, once the United States chooses to withdraw, Russia will also take corresponding countermeasures.

       In addition, for the United States to announce a new round of sanctions against Russia, Putin said that there is a commercial purpose behind this move by the United States.

       Putin also said that the media in Britain, the United States and other countries are constantly influencing the political process in many parts of the world, and their influence covers every corner of the world. However, it is difficult for Russian media to compare with those in these countries in scale and influence. However, once Russia discovers that the US government suppresses Russian media, it will decisively take reciprocal measures to counter it.

       In addition, when talking about the topic of destroying weapons of mass destruction, the contradiction between Russia and the United States is still prominent. Putin said that in 2001, the United States withdrew from the Anti-Ballistic Missile Treaty initiated and signed by it and refused to fulfill its international obligations under the Treaty. Although the United States is still a party to the Chemical Weapons Convention, its chemical arsenal is still the most powerful, and the United States has postponed the deadline for its destruction of chemical weapons from 2007 to 2023, while Russia destroyed all its chemical weapons on September 27th this year. In addition, Putin also pointed out that when the United States fulfilled the Plutonium Management and Disposal Agreement signed by Russia and the United States in 2000, it only adopted the disposal method of diluting plutonium concentration and underground isolation storage, which was completely inconsistent with the provision of "irreversibly converting weapons-grade plutonium materials into civilian nuclear reactor fuel" in the agreement.

       [Situation on the Peninsula] Putin said that the solution to the DPRK nuclear issue must rely on dialogue.

       In addition to talking about Russia-US relations, Putin also mentioned the situation on the Korean Peninsula in Sochi on the 19th. Putin said that Russia resolutely implements relevant UN Security Council resolutions, but does not allow tensions on the Korean Peninsula to escalate. Putin stressed that the solution to the DPRK nuclear issue must rely on dialogue, not force, and Russia opposes war and chaos on the Korean peninsula.

       Putin also said that the United States threatened to "pre-emptively attack North Korea’s nuclear weapons and missile facilities, etc.", but he doubted whether the United States could "strike at all."

       [Regional Hotspots] Putin talks about Syria and Ukraine.

       In addition to the Korean peninsula, Putin also has the latest statement on the Syrian crisis that has erupted for more than six years and the Russian-Ukrainian border issue.

       When talking about the situation in Syria, Putin said that he has reason to believe that with the support of the Russian army and other allies, the Syrian government will "defeat terrorist organizations such as extremist organizations in the near future" — — However, this does not mean a complete victory in the war on terrorism in the region and even in the world, because terrorism has complicated reasons and cannot be eradicated in a short time.

       Putin said that the Syrian crisis has broken out for more than six years, and the Syrian peace process is moving in a positive direction recently. He suggested that a "general meeting of all Syrians" can be held in due course, and all factions in Syria can send representatives to discuss the future of the country — — If this congress is strongly supported by regional countries and international powers, then the political reconciliation in Syria will take a big step, and then the drafting of a new constitution can be discussed.

       Referring to the Ukrainian issue, Putin said that Russia cannot close its border with eastern Ukraine, because this will lead to a terrible massacre in eastern Ukraine.

       He also stressed that Russia has always strictly abided by the new Minsk agreement, and the current problem lies with the Ukrainian government. He urged the EU to "make great efforts" to change the current situation.

Professional counterfeiters also need to fight counterfeiting.

 

  Mr. Yuan never imagined that he would meet such customers. He opened a small supermarket in xinhe town, Wenling City, Zhejiang Province. In December 2018, a customer bought many pieces of food in the small supermarket many times, and these foods all passed the shelf life. After that, the customer claimed compensation from the supermarket and also sued the People’s Court of Wenling City, Zhejiang Province. A few days ago, Mr. Yuan reached a mediation agreement with the customer and compensated the other party for 4,500 yuan.

  Prosecute again after a trial in absentia

  This customer is surnamed Zhang, 40 years old, from Hubei.

  In July 2019, Zhang filed a case in the People’s Court of Wenling City, Zhejiang Province by mailing prosecution materials to sue the supermarket operated by Mr. Yuan. The item involved is a box of spore powder. The price of spore powder is 398 yuan, the production date is December 10, 2016, the shelf life is 24 months, and the purchase time is December 17, 2018. Zhang claimed 10 times compensation, that is, 3,980 yuan, from the supermarket on the grounds that the spore powder expired.

  As scheduled by the court, the case is scheduled to open on August 1, 2019. Before the trial, Zhang applied for an extension of the trial, but the court rejected his application because he did not provide reasonable reasons. On the day of the trial, Zhang did not appear in court, and the case was dismissed.

  On April 1, 2020, Zhang once again filed a case by mailing materials. The items involved this time are two bottles of drinks. Zhang said that he bought these two bottles of drinks twice on December 16 and 17, 2018. The production date of these two bottles of drinks is March 6, 2018, with a shelf life of 9 months, and the price is 4 yuan. Zhang’s appeal is to compensate 1000 yuan for each bottle of drinks.

  On May 13th, Wenling Court heard the case. During the trial of the case, Zhang changed the litigation request and added the compensation request for the above spore powder, that is, he asked the supermarket to refund 406 yuan for the three purchases, compensate 5980 yuan, and refund 6386 yuan.

  Proud of suing illegal businesses

  During the epidemic prevention and control period, the court held a video session, and the supermarket arrived at the court to respond, while Zhang participated in the trial through remote video in Hubei.

  During the trial, Zhang showed a video record of three purchases of goods. Every time he made a purchase, Zhang began to record videos before entering the store until the end of the purchase. Among them, close-ups were also taken on the production date and shelf life of the goods. In addition, Zhang also showed a shopping receipt.

  The judge asked Zhang why he went to the supermarket to buy goods. Zhang replied that he traveled to Wenling and passed the supermarket, so he went into the store to buy things.

  The judge asked: Why do you have to make a video every time you shop? Zhang said that he had bought inappropriate products, but the merchants denied it. He always hated this behavior of the merchants, so he developed the habit of making videos.

  The judge asked: After I bought the drink for the first time, I found it was an expired product. Why did I buy it for the second time? Zhang replied: The state supports consumers to know and buy fakes.

  The judge asked: Do you think you are a consumer or a professional counterfeiter? Zhang said that professional counterfeiters are not a legal concept. Professional counterfeiters should be courts, procuratorates, market supervision and management bureaus, public security bureaus, food and drug environmental investigation detachments, etc. As a citizen concerned about food safety, according to the right of claim granted by law, illegal businesses that deliberately sell food that do not meet food safety are punished. As a citizen, he is proud of suing illegal businesses.

  The supermarket has no choice but to mediate.

  In January 2019, Zhang complained to the Wenling market supervision department that the supermarket sold expired food. According to the report posted by Zhang, Zhang and his friends bought five bottles of drinks in the supermarket on December 16th, 17th and 18th, 2018, totaling 20 yuan.

  Zhang’ s complaint report request is to order the supermarket to refund and compensate 5,000 yuan; The supermarket was ordered to bear all kinds of expenses arising from the complaint of 2331 yuan, and the reward was 2000 yuan or more according to the highest standard according to the relevant reward regulations.

  The market supervision department filed a case for this, and in July 2019, it imposed an administrative penalty on the supermarket and ordered the supermarket to rectify the failure to establish a food purchase inspection record system; He was warned that his illegal income was 418 yuan and he was fined 65,000 yuan.

  The supermarket did not agree to the compensation proposed by Zhang, and Zhang appealed to the court. During the trial, the supermarket said that Zhang was blackmailing. In addition to their supermarkets, Zhang also made claims in other supermarkets nearby. Other supermarkets chose to settle things with Zhang in order to avoid troubles.

  After the trial, the supermarket agreed to mediate with Zhang. Mr. Yuan said that Zhang kept changing his claims, and he really didn’t have the energy to cope with Zhang’s prosecution. On May 18, 2020, the two parties reached a mediation agreement, and the supermarket voluntarily compensated Zhang for 4,500 yuan and 200 yuan, and Zhang no longer claimed any rights from the supermarket.

  Repeated lawsuits were mostly rejected.

  In recent years, there are more than 120 cases of consumer disputes brought by Zhang in Zhejiang Province, involving items such as food, medicine and mobile phones. Among them, there are more than 10 cases decided, and the vast majority of the judgment results are to reject Zhang’s claim.

  On August 4, 2016, Zhang bought five pieces of clothing in a clothing store in Hangzhou. The sales staff told him that all the five pieces of clothing were sold at a 50% discount, compared with a 60% discount in July 2016. Zhang bought it at 50% off the tag price, and paid a total of 5474 yuan.

  On September 10, 2016, Zhang went to the clothing store to buy 10 pieces of clothing. The salesperson told the 10 pieces of clothing that they were all sold at a 50% discount, which was previously sold at a 30% discount. Zhang bought it at 50% off the tag price, and paid a total of 10,473 yuan.

  In October 2016, Zhang reported to the local market supervision department on the grounds that the defendant was suspected of price fraud and illegal propaganda. In December 2016, Zhang complained to the local government on the grounds of price fraud, asking the clothing store to refund one and lose three, and the clothing store refused to mediate.

  On February 28, 2017, the local government made an advance notice of administrative punishment on the clothing store, arguing that the basic price of the discount was not indicated on the discount bulletin board set up by the clothing store in the store, which belonged to the situation that the operator violated the clearly marked price, so the clothing store was fined 3,000 yuan.

  In November 2017, Zhang sued the court and asked the clothing store to refund 15,947 yuan and triple the compensation of 47,841 yuan.

  The court found through trial that Zhang went to the clothing store for shopping for the third time in July 2017. Since 2015, Zhang has filed dozens of consumer rights litigation.

  The court held that consumers’ rights and interests are protected by law if they need to buy or use goods or receive services for their daily consumption. In this case, Zhang went to the clothing store twice to buy clothes, and the time interval was about one month, and he bought 15 pieces. Audio and video recordings of the two shopping trips were taken from unconventional angles; In October 2016, Zhang complained to the administrative department about the two purchases in this case on the grounds of price fraud and illegal propaganda, but in July 2017, he went to the defendant for the third time to shop; In recent years, Zhang has filed dozens of consumer rights protection lawsuits, and there are cases in which he filed many lawsuits against the same type of operators in the same court at a certain period, which obviously violates the common sense of ordinary consumers.

  The court also held that Zhang knew before making the intention to buy that the discount informed by the salesperson was based on the tag price and the price actually sold in the near future, and combined with his legal experience of asking for a refund of one and three on the grounds that the propaganda language was illegal, it was impossible for him to make a false intention to buy because of propaganda and shopping guide behavior.

  Therefore, the court rejected Zhang’s claim that he was buying for the purpose of living consumption and was defrauded, and rejected all Zhang’s claims.
