Recently, news from the Chongqing Municipal Housing and Urban-Rural Construction Committee stated that during the "13th Five-Year Plan" period, Chongqing will speed up its rail transit planning and construction, and fully promote the implementation of the urban improvement action plan and the urban rail transit network plan, and achieve an average daily passenger flow of 3 million passengers. Secondly, the daily maximum passenger flow has reached 3.87 million passengers, and the backbone of rail transit in the public transportation system has become increasingly prominent. In Chongqing, rail transit is the first choice for public transportation.

The total mileage of Chongqing rail transit reaches 370 kilometers

At 14:00 on December 28, 2018, the northeast half of the Chongqing Rail Transit Ring Line officially opened for trial operation.

The northeast half-ring project of the Chongqing Rail Transit Circle Line starts at Chongqing Library Station in Shapingba District in the west and ends at Haixia Road Station in Nan'an District in the east, spanning 4 administrative regions. The southwestern half-ring of Chongqing Rail Transit, with a total length of about 17 kilometers, starts at Fengmingshan Station in Shapingba District in the west, crosses the Egongyan track special bridge and connects with Haixia Road Station on the northeast half-ring, and will be on December 30, 2019. Open daily.

According to data from the Municipal Housing and Urban-Rural Development Commission, during the "13th Five-Year Plan" period, Chongqing started to construct the second phase of the construction plan for the second phase of the construction plan of line 6, line 9, line 10, and the third phase of the construction plan. The second phase of Line 4, Line 18, the northern extension of Line 5 and the 169-kilometer line of the Bi Copper Line; the northern extension of Line 3, the first phase of Line 4 and the first phase of Line 5 in the second phase of the construction plan The northern section (Dashiba ~ Garden Expo Center), the first phase of Line 10, the ring line (Chongqing Library Station ~ Erlang Station) and Jianbi section of 127 kilometers.

It is expected that by the end of 2020, the second phase of the branch line of Metro Line 6 and the southern section of the first phase of Line 5 (Shiqiaopu~Tiaodeng) and the ring line (Erlang~Chongqing Library) will be fully operational, and the total mileage of Chongqing rail transit will reach 370 Kilometers.

Plan to build 8 rail transit lines in the next five years

Rail Transit Line 18 has a total length of 29 kilometers, from Fuhua Road Station to Tiaodeng Station, with a total of 19 stations, of which 7 are aboveground stations and the remaining 12 are underground stations. It is expected to open to traffic in 2023. The extension section of Line 18 in Yuzhong District is from Fuhua Road Station to Xiaoshizi Station, with a total length of 11 kilometers. For Chongqing, the rail transit construction in Yuzhong District is more concentrated in the upper half of the city, while the lower half is almost blank. The construction of Rail Transit Line 18 will inject new blood into the lower half of the city and bring new hope.

The second phase of Metro Line 4 is also under construction and is expected to be completed and opened to traffic in 2022. At that time, the two major areas of Yufu and Longxing in Liangjiang New District will be connected; connecting Shapingba District, Yuzhong District, Jiangbei District, Yubei District and The Huashigou parking lot access tunnel of the second phase project of Metro Line 9 in Liangjiang New Area has been successfully completed. The main structure of Langui Avenue Station has been successfully capped, and the main structure of Chunhua Avenue Station has also been capped. It is expected to open for trial operation by the end of 2022.

According to the relevant person in charge of the Chongqing Municipal Housing and Urban-Rural Development Committee, during the "13th Five-Year Plan" period, the construction of Chongqing rail transit lines under construction will improve quality and speed. The fourth phase of the construction plan combines the first three phases of the construction plan and deeply integrates the latest results of the new round of urban and rural general plans. Through the construction of the central main urban rail network, it strengthens the north-south traffic connection within the east-west trough and shortens the main urban area and the east-west trough. The space-time distance of the main city further supports the integrated development needs of the main city.

It is reported that the construction plan for the fourth phase of Chongqing rail transit involves 8 lines, 198 kilometers, and a total investment of about 136.6 billion yuan. They are Line 15, the first phase of Line 7, the west extension of Line 4, and the Chongqing East of Line 6. The extension of the station, the extension of Line 27, the extension of Line 18, the first phase of Line 24 and the first phase of Line 17 are planned to be fully opened in two years and fully open in five years.

A number of independent innovation technologies are at the forefront of the world

It is understood that the Egongyan Track Bridge is the world’s first self-anchored suspension bridge with a main span of 600 meters. Thanks to the support of track technology, the Egongyan Track Bridge adopts a system of cable-stayed first and suspended later. Successfully constructed. The bridge not only connects Xiejiawan Station and Haixia Road Station, but also realizes the first subway connection between Jiulongpo and South Bank, which greatly facilitates the travel of citizens along the line.

The construction of Chongqing rail transit has also led many technologies to the forefront of the country and even the world through independent innovation: the construction of the largest rail transit cable-stayed bridge in the field of urban rail transit engineering in China and the second largest span in the world-Caijia Jialing River Bridge ; Successfully traversed the Zhongliang Mountains known as the "Geological Museum"; composite TBMs are widely used in soft and hard rock formations; built the longest mountain tunnel in the field of urban rail transit engineering in China-the Tongluoshan Tunnel on Line 6; independent research and development And put into use the new model car body and key technology integration monorail technology and other technologies.

In addition, urban rail transit construction projects have won numerous awards. The first phase of the rail line 10 project won the 2018 China Construction Engineering Luban Award; the self-developed As-type urban rail vehicle with strong climbing ability and small turning radius has been put into use and is in good operation.

The relevant person in charge of the Chongqing Municipal Housing and Urban-Rural Development Committee emphasized that with the completion and improvement of Chongqing's rail transit system and the operation of straddle-type monorails, traffic congestion in the main urban area has been significantly improved, and the value and quality of the city have been significantly improved, which has promoted society in all districts of Chongqing. economic development. In the future, Chongqing's rail transit system will become a beautiful urban landscape that will further enrich Chongqing's characteristic culture. Editor/He Yuting
