If you ask, what is the most popular way of travel among office workers?
Many people may choose the subway. Rail transit represented by subways provides people with a more convenient way to travel.
In the past three years, the mileage of newly built subway lines nationwide has been almost as much as that in the previous 50 years. While alleviating the pressure on urban transportation and making travel easier, the subway industry is developing rapidly in places we cannot see.

At 8 o'clock in the morning, at the subway station of Chengdu South Railway Station in Sichuan, the stationmaster on duty Jia Tingting was nervously communicating with the dispatching room, and an empty car that passed the station was rushing here.
Deputy District Mayor of Chengdu Metro South Railway Station Jia Tingting: The situation of empty trains at the large station was launched on weekdays, which solved a peak in the cross-section. The peak value of the cross-section reached about 111%.
At present, the driving interval of Chengdu Metro Line 1 during peak period is 120 seconds, which has reached its limit. According to the quota standard of 1,460 people per subway, 30 trains per hour can only transport less than 44,000 people.
can be found at Jia Tingting's station. The peak cross section is above 51,000 people, and at most it is close to 55,000 people. This means that during the morning rush hour every weekday, there is at least 8 people standing in the subway carriage of Chengdu Line 1 in a square meter of space. In order to increase transportation capacity, more than a dozen new subway lines have been built.
As an important node for Chengdu Metro Line 18 , the 9.7-kilometer-long Longquanshan Tunnel has just been completed. The time for opening this tunnel is 2/3 shorter than that of traditional construction methods.
Chief Engineer of the Longquanshan Tunnel Section of China Power Construction Chengdu, Zhang Wenxuan: Two inclined shafts are added in the middle of the tunnel, and the working surfaces of the entire tunnel are increased to 12. If the excavation ends are divided into two ends, it will be 2023 and 2024.
Currently, in Chengdu, there are 529 important subway construction sites like Longquanshan Tunnel, and at peak times there are nearly 50,000 people working at the same time.
"In 2018, 60 billion yuan was invested. There were 14 lines under construction at the same time during peak periods, exceeding 450 kilometers. This is the record we have created in China at present." Zhu Junping, vice chairman of Chengdu Rail Transit Group Co., Ltd., said.
is in short supply! The shield "old driver" has become a "hot commodity"
At present, there are 35 cities across the country that have opened subways, with a total mileage of more than 6,000 kilometers, and many projects are under construction. The subway construction is in full swing, but some important positions are short of talents.

In recent days, the project of shield driver Jia Guotao has reached the most critical moment.
He operated a shield machine worth tens of millions of yuan to "surpass No. 1" and dived forward at a speed of about one meter per hour. Above him was Metro Line 1, which was already operated by Zhengzhou City. Although he stays 30 meters deep every day, there are still many people thinking about Jia Guotao.
China Construction Second Bureau Shield Driver, Zhengzhou Rail Line 3 Shield Driver Jia Guotao: Now that I call, I will look for those who know or not, and I am looking for people who are looking for Shield Driver positions, which means that the gap is relatively large now.
In recent days, the company has sent two new shield drivers to learn from the "old driver" Jia Guotao. Jia Guotao knew that the national subway industry is developing rapidly and there is a shortage of shield drivers everywhere, which means that the company will soon have new projects.
Shield structure manager of Zhengzhou Rail Line 3, China Construction Second Bureau, Chen Zhiwen: Who is more skilled in the same industry? We will find it with high salaries. In addition to the five insurances and one fund, the income of the year is about 200,000 yuan.
Chen Zhiwen told reporters that there are now more than 2,000 shield machines under construction nationwide, and more planned projects are waiting for shield drivers. He is full of confidence in the future.
More than
cities have been approved to build subways
The hot subway construction has injected strong vitality into the city and brought huge economic benefits. However, construction, operation and maintenance are also high costs. Faced with huge market prospects, subway construction cannot be rushed, and planning must be discussed in the long term.

In a shield machine production workshop in Zhengzhou, Henan, Anjianyong is communicating the equipment parameters with the manufacturer in advance. Having the most advanced equipment is crucial to taking the next project.
An Jianyong, chief engineer of the Rail Transit Department of the Beijing Branch of China Construction Second Bureau: Because the time is tight and the task is heavy, we recruit soldiers in several places, and it is also an urgent task to prepare for the shield machine selection in advance. Zhang Kun, a salesperson of
China Railway Equipment Shield Machinery, also introduced: "In 2019, more than 30 new orders were signed. The order volume of the whole year is about 100 units, and there are still queuing up." The shortage of
shield machine means that the subway project is developing rapidly. According to statistics, as of the end of 2018, 35 cities and 4,354.3 kilometers of subway lines were put into operation in mainland China, and there were 63 cities that have been approved for the construction of subway projects.
Experts said that at present, the subway passenger volume in many cities has reached nearly half of the total public transportation volume, and it has a huge role in alleviating traffic congestion and optimizing urban space.
Liu Jianfeng, deputy chief engineer of Beijing Urban Construction Design and Development Group: Beijing rail transit carries more than 10 million passenger volume every day. You can imagine, if we don’t have more than 1,000 kilometers of rail transit, what would road traffic look like?
According to research by the China Urban Rail Transit Association, every 100 million yuan investment in the subway industry can directly drive economic growth of 263 million yuan and indirectly drive more than 800 million yuan.
The huge economic benefits have caused the subway projects launched in various places to explode. In 2018, mainland China completed a total investment of 547 billion yuan in urban rail construction. By 2025, the national urban rail transit mileage is expected to exceed 10,000 kilometers.
Experts said that although the subway industry is optimistic in the long run, for more small and medium-sized cities, the subway is expensive and the planning needs to be discussed in the long run.
