Guinan high -speed rail (Guizhou section) enters the stage of comprehensive rail paving

Line launching ceremony site

The Guiyang to Nanning high -speed railway (hereinafter referred to as the Guidan high -speed railway), which participated in the construction of the first bureau of China Railway, entered the entire rail paving stage on August 26, laying a solid foundation for the completion of the entire line in 2023.

According to Liu Chaohong, the person in charge of the project department of the Guizhou section of the Guizhou Section of the China Railway 1 Bureau, the project department undertakes about 388 kilometers of rail paving projects in the Guizhou section of Guizhou high -speed rail and 90 groups of roads. The Guizhou section of the Guinan high -speed rail has the characteristics of bridge tunnel, small operating space, large line ramp, and a maximum slope of 27 ‰. In order to ensure the safety of rail paving, the project department carried out the internal combustion locomotive tunnel paving operation of the railway engineering. Exercise, and equipped with emergency rescue items such as oxygen cylinders, anti -virus masks, and quick -acting savior pills. By adopting a ventilation equipment on the construction train, set up full -time toxic and harmful gas detectors to test the tunnel gas for 24 hours to further improve the tunnel gas to further improve The rails in the tunnel are safe. Construction units set up engineering line management scheduling and command centers, unified command, unified dispatch, and monitor the operation status and operating location of the equipment such as rail pavers, long track transport vehicles, welded rail vehicles and other equipment to ensure the safety of rail paving operations and construction lines. Manage safety and orderly.

Low staff on -site work

It is understood that the China Railway One Bureau adopts a professional transportation and management model, and has invested more than 700 operators, two sets of rail paving units, two long rail transport vehicles, a set of K922 mobile flashing welding machines, a set of UN5-150ZB type Mobile flashing welding machine and 12 Tai -China wind four internal combustion locomotives. In order to improve the rail paving efficiency, a new type of long rail traction vehicle with automatic rails and cross -line transfer of automatic tracks and cross -line transfers of the entire machine. Compared with the traditional construction process, laying one pair of 500 -meter long rail can reduce 2 operators, saving about 20 minutes of operations for about 20 minutes. time.

According to the relevant person in charge of the Guizhou Company of the Shanghai -Kunming Passenger specialty, Guinan High -speed Railway is an important part of the "Eight vertical and Eight High -speed Railway" high -speed railway network Baohai Railway (Baotou to Haikou) channel in China. Five "planning new channels in the western land and sea, and the first dual -line high -speed railway with a speed of 350 kilometers per hour in the Southwest.

Low staff on -site work

After the Guinan high -speed rail is completed and opened to traffic, the revolutionary and ethnic minority areas along the routes, Huanjiang and other revolutionary areas will be entered into the era of high -speed rail. By then, from Guiyang to Nanning, it will be shortened from more than 5 hours to 2 hours. At the same time, the Guidan high -speed rail will be connected with many high -speed rail lines such as Cheng Gui, Guiguang, and Shanghai -Kunming, which will have positive significance for improving the Southwest Railway Network and enhancing the communication between the southwest to western Guangdong.
