Recently, the Chengdu-Dazhou-Wanzhou high-speed railway subgrade, bridge, and tunnel construction has set off an upsurge. All 16 bidding sections have started construction, and 12,000 people have fought hard and pressed the construction accelerator button.

Striving for spring, setting off a construction boom across the board

According to reports, the Guangming Tunnel with a total length of 8,468.8 meters is located in Kaijiang County, Sichuan Province and Kaizhou District, Chongqing City. It is located at a key node connecting Sichuan and Chongqing. At present, 66 meters of excavation has been completed at the exit of the Guangming Tunnel, and the construction of the inverted arch will begin soon. According to Wu Xiaoping, the manager of the first work area of the Chengdu-Wanzhou High-speed Railway Engineering Headquarters of the China Railway Beijing Engineering Bureau Group Co., Ltd., the contractor, the other two tunnels in the tube are under construction on the side slopes of the openings, and 107 bridge pile foundations have been completed, accounting for the total design. 56.3% of the bridge project, the follow-up caps, piers and continuous beams of the bridge project are advancing in an orderly manner according to the construction plan. According to Bai Likang, the safety director of the second work area, since the construction of the cave in December last year, the operators have adopted a 24-hour shift system to ensure that the construction plan is advancing in an orderly manner.

Also ushering in the construction node is the Dengta Village Super Bridge not far from the Guangming Tunnel. The project has recently completed the construction of No. 15 pier, which is also the first pier that has been poured for the Yingshan-Wanzhou section of the Chengda-Wanzhou high-speed railway.

In Anju District, Suining City, the first pile of the Degongcun Super Bridge was successfully drilled. At present, the bridge has 4 pier certificates in pile foundation work. The drilling of the pile foundation of the bridge marks the overall progress of the overall construction. According to Li Qianghua, commander of the 5th Bid Project Headquarters of the Chengda-Wanzhou High-speed Railway of the China Construction Eighth Engineering Bureau, the total length of the Degong Village Super Bridge is about 3.9 kilometers, and it spans four existing railways including the Dacheng Single-track Railway, the Suixin Uplink Line, and the Shanghai-Chengdu Double-track Railway. Wired is an important and difficult control project of the bidding section. At the same time, there are 49 sections of subgrade construction in the project, and a total of 705,500 cubic meters of earth and stone have been completed, accounting for 22.1% of the total design; 41 bridge projects, 22 have been opened, and a total of 14,306 meters of pile foundations have been completed, accounting for 22.1% of the total design. 12.6%, and the substructure such as caps and piers is being advanced in an orderly manner.

People along the line are looking forward to this high-speed railway. Since the start of construction, the local government has given great support to the construction. He Wanfa, commander of the Dazhou headquarters of Chengdawan High-speed Railway Co., Ltd., said that they will increase the construction organization in the future, promote more physical quantities to be implemented within the year, and promote the early completion and opening of the project.

The Chengdu-Wanzhou high-speed railway is an important part of the riverside channel of China's eight-vertical and eight-horizontal high-speed railway network. It connects eastern Sichuan and northern Chongqing. The main line has a total length of 477 kilometers and a design speed of 350 kilometers per hour. After the project is completed and opened to traffic, it will form a 350-kilometer-per-hour high-speed rail passage from Chengdu to the east and north to Sichuan, which is of great significance to the implementation of national strategies such as the construction of the Chengdu-Chongqing economic circle and the Yangtze River Economic Belt.
