On December 27, Chengdu, Sichuan, completed the simultaneous opening of three subway lines for a total of 101 kilometers, which not only officially allowed Chengdu's subway to enter the "300 kilometers era", but also set a new record for the one-time opening and operation of urban rail transit in China.
Since the first subway line of the New China was opened to traffic in Beijing in 1969, in the past 50 years, from the exploration and construction to the addition of more than 400 kilometers per year, from imitation learning and innovation to the export of advanced technology, products and services abroad, China The subway network is like large arteries all over the city, constantly transporting nutrients and carrying the development of the city.
Become standard for urban happiness index
"My family lives in Tianfu New District. The unit is in Qingyang District. Before that, I had to take a bus every day before work. Not only was the car crowded, but it was easy to be late with a traffic jam." On the morning of the 27th, the newly opened Chengdu Metro Line 5 Jincheng Avenue Xu Shenmiao, a citizen of Chengdu waiting at the station, said with a smile that the subway is not only spacious and comfortable, but also saves time, and will take the subway to and from work every day in the future.
It is understood that the development of rail transit in Chengdu has been slow for a long time in the past, and two lines were not opened until early 2015.
"The subway is a standard configuration of a city's happiness index, which will not only help to reduce the distance of the city, but also greatly improve the travelling life of the citizens." Zhu Junping, deputy chairman of Chengdu Rail Transit Group, said that the current day of Chengdu Metro With an average passenger flow of more than 4 million people, it is believed that this number will increase significantly after the "New Third Line" is put into operation.
The data shows that as of September 2019, 39 cities in China have opened rail transit with 6333.3 kilometers of line operation. It is estimated that by the end of 2019, the total mileage of urban rail transportation in the country will reach 6,600 kilometers and the annual passenger volume will exceed 25 billion. .
"From paper tickets to bus cards to mobile payment, from often crowded to spacious and comfortable, more and more rail transit is put into operation, and the transportation department has gained more experience to facilitate passenger travel." Deputy Deputy Transport Services Department of the Ministry of Transport Director Cai Tuanjie said that through continuous polishing of operation services, today's urban subways have generally shortened departure intervals, optimized guidance signs, and formed volunteer teams, which have been well received by more and more passengers.
Continuous innovation in subway construction technology
In the afternoon of December 27, a Boeing 777 passenger plane was fully parked at Chengdu Shuangliu International Airport. At the same time, the Chengdu Metro Line 10 Phase 2 project just started more than 20 meters below the taxiway runway. Speeding at 100 kilometers per hour. When the subway stops at Shuangliu Airport Station, a continuous stream of passengers may not know yet. This is the first construction case in China where a shield tunnel crosses the airport through water-rich sand and egg geology.
"Due to the special nature of the airport runway, once the settlement during construction exceeds 5 mm, the airport will be forced to close urgently, and 150,000 people will be prevented from traveling every day." Shi Zhendong, chief engineer of China Railway Construction Southwest Regional Headquarters, said that using a shield machine Crossing the runway where an airplane takes off and landing every 2 minutes and successfully achieving "zero settlement" can be said to be the epitome of the development of China's rail transit technology.
It is understood that before the 1990s, due to multiple factors such as technical reserves and talent conditions, China's subway construction cycle was long and slow. It took nearly 20 years for the Beijing Subway to go into operation, 32 years for the Guangzhou Subway, 36 years for the Shanghai Subway, and 14 years for the Tianjin Subway. During this long period of experimental exploration, China's subway operating mileage has grown very slowly.
"It can be said that urban rail transit is one of the most practical and innovative landmarks in China's reform and opening up." Xie Zhengguang, president of the China Urban Rail Transit Association, stated that while "grossing one poor and two innocent", he is working on subway construction. It has been carried out in parallel with dozens of urban subway construction projects; from "cut-out" subways using thousands of trucks to move the earth to "quiet" work using new technologies and new methods; from importing vehicles from other countries to Chinese-made vehicles "through" the world Continents ... The world-leading China Metro is quietly changing the travel of people in many countries around the world.
Get through the "last mile" of the Spring Festival
Facing the coming Spring Festival in 2020, rail transit will also play a more important role.
"For me, the most difficult thing to do during the Spring Festival every year is not to buy train tickets, but how to go home after getting off the train." Said Lin Zhipeng, a Wuhan guy who works in Beijing, during the Spring Festival in previous years, took the train from Beijing to Wuhan. It takes more than four hours, but sometimes it takes almost two hours to get home from Wuhan Railway Station.
"Taxis can't be reached at peak times. People in the subway line up to buy tickets and go through security checks are more than 50 meters away. They can't squeeze in at all." Recalling the experience of going home during the Chinese New Year, Lin Zhipeng couldn't help sighing.
It is reported that the situation of queuing up for subway tickets during the Spring Festival transportation this year will be greatly alleviated. Cai Tuanjie said that up to now, a total of 275 prefecture-level cities across the country have issued interconnected cards, and 27 cities can use interconnected cards for subway lines. "The first thing I did when I arrived in a new city was to buy a subway ticket. Now that the bus card is networked across the country, in most cities, you only need to take out the card for daily commuting to take the subway and bus. .
At the same time, in order to make passengers' transfer experience easier, Beijing South Railway Station, Nanjing Railway Station, Hangzhou East Railway Station and other railway stations also implement a new model for railway passengers to enter the subway without security check, allowing passengers to "seamless transfer". "Hangzhou East Railway Station implements the" one-way inspection-free "plan for the Spring Festival Transport this year. Passengers can go to the subway station by transferring to the subway, and there is no need to go through security checks." Hangzhou East Railway Station staff said.
"According to the current planning, during the peak of the Spring Festival this year, subway lines in some cities will also extend operating hours and shorten vehicle intervals, so that rail transit will play a more important role in the 'last mile' of the Spring Festival." Cai Tuanjie said .
