Recently, two high-speed railways with a design speed of 350 kilometers per hour ushered in new progress in construction.

Guinan high-speed railway has entered the static acceptance stage

On February 16, 2023, the Guizhou section of the newly-built Guiyang-Nanning high-speed railway began static acceptance, marking that the entire Guinan high-speed railway has entered the static acceptance stage. Static acceptance means that the railway construction unit organizes an acceptance working group to inspect the construction project to confirm whether the project is completed according to the design and the quality is qualified, and whether the system equipment has been installed and debugged. After the static acceptance, dynamic inspection, joint debugging and joint test and operation test will be carried out to prepare for the opening and operation of the line.

Guinan high-speed railway officially started construction on the whole line in December 2017, spanning the northwest of Guangxi Zhuang Autonomous Region and southeast of Guizhou Province, with a design speed of 350 kilometers per hour and a total length of 482 kilometers. It is expected to open within this year.

The static acceptance plan is to organize and complete the acceptance of public works, electric traction power supply, electric power, communication, signal, information, disaster monitoring, housing construction, environmental protection and water protection and other related supporting projects before March 15, and complete the fire protection by the end of May. , environmental protection, water conservation, archives, elevators and other special inspections.

In order to ensure the smooth progress of static acceptance, the railway department organized business backbones to set up a static acceptance leading group and 10 professional acceptance groups including engineering, communication, and signal to carry out acceptance work.

The Guinan High-speed Railway is an important part of the Bao (Silver) Sea Corridor in my country's eight-vertical and eight-horizontal high-speed railway network. After it is completed and opened to traffic, the travel time from Nanning to Guiyang will be shortened from the current 5 hours to about 2 hours. , Du'an, Mashan and other places will enter the era of high-speed rail, and will further improve the high-speed rail network in Southwest my country, and promote the economic and cultural integration and development of ethnic minorities in Southwest China.

The Sichuan Section of the West-Chongqing High-speed Railway has entered the stage of comprehensive main construction

On February 17, at the construction site of the Tongbohe Super Bridge on the Sichuan section of the Xi'an-Chongqing high-speed railway, a piling machine laid the first pile, marking that the Sichuan section of the West-Chongqing high-speed railway has entered the main construction stage.

The West-Chongqing High-speed Railway is an important part of the Beijing-Kunming Passage and the Bao (Yin) Sea Passage in my country's eight-vertical and eight-horizontal high-speed rail network. , 59 tunnels, 2 subgrade sections, and the bridge-tunnel ratio is as high as 72%.

In order to achieve various construction goals on schedule, the construction unit is guided by management and technological innovation, and promotes the construction of the project in a scientific, orderly, safe and high-quality manner. The bridge and tunnel projects on the main line have entered the substantive construction stage. Keywords: engineering news, engineering construction information, engineering construction

After the completion of the West-Chongqing High-speed Railway, it will be connected with the Chengdu-Chongqing High-speed Railway, the Zhengyu High-speed Railway, the Chongqing-Kunming High-speed Railway, the West-Yan High-speed Railway, and the West-Ten High-speed Railway, which are under construction. This will further improve the road network structure in the central and western regions. It will greatly facilitate the travel of people along the route, and is of great significance to consolidating and expanding the achievements of poverty alleviation, comprehensively promoting rural revitalization, helping urban-rural integration and coordinated regional development, and forming a new pattern of western development.
