Recently, the country’s largest-scale existing high-speed rail line replacement construction undertaken by the Guangzhou Public Works Overhaul Section of the Guangzhou Railway Group has successfully concluded.

It is reported that the rail change was carried out in the interval between Zhuzhou West Station and Hengshan West Station on the Beijing-Guangzhou High-speed Rail Downline. It lasted more than one month. The rail change task totaled 16 kilometers, which is the longest high-speed rail construction in the country. .

　　It is understood that since the Wuhan-Guangzhou section of the Beijing-Guangzhou high-speed rail was opened to traffic in 2009, it has transported nearly 600 million passengers and operated more than 600,000 mobile trains.

The high-speed train leaves the rails with wear and tear day after day.

After 11 years of operation, most of the rail wear values ​​are close to the overhaul standard, and new rails need to be replaced gradually.

　　Since undertaking the task, the Guangzhou Public Works Overhaul Section has made sufficient preparations in the early stage of construction. The section leaders have organized professional departments and construction workshops to hold special meetings, and held high-speed rail construction training courses, carried out comprehensive safety assessments, and held a mobilization meeting.

At the same time, the section appointed Huaihua rail-changing workshop, Hengyang rail welding workshop, road material transportation workshop and self-wheeling equipment workshop and other workshops with rich experience in high-speed rail construction to work together. The number of participants in the construction reached 338, which is currently the largest number of people participating in the war. A high-speed rail construction.

　　The reporter saw at the scene that the construction adopts an integrated rail-changing mode, using integrated rail-changing engineering vehicles to unload new long rails, replace steel rails, recycle old long rails, rail welding joints, and line arrangement and construction. All construction links are coordinated and smoothly connected. .
