On September 24, 2021, after six months of hard work, the Lan-Xin High-speed Railway Shandan Racecourse station, which was constructed by the 21st Bureau of China Railway, was completed and passed the static acceptance. An additional passenger station built on the existing high-speed rail business lines. After Shandan Racecourse Station is completed and put into operation, it will further play the role of the Lanzhou-Xinjiang High-speed Railway in radiating the cities along the route. Shandan Racecourse is located in the middle of the Hexi Corridor and at the northern foot of the Qilian Mountains, with a total area of 3.29 million mu. It is currently the largest and oldest in the world. Horse farm. The Lan-Xin High-speed Railway Shandan Racecourse Station was originally a third-class overpassing station, mainly for the safe and punctual passage of the Lanxin High-speed Railway trains through the 7 tunnel groups between Gansu Shandan Junmachang and Qinghai Haomen Station. The new Shandan Junmachang Station passenger transportation supporting project has a total construction area of more than 2,000 square meters. The overall shape of the new station building adopts the "mountain" shape, which means Qilian Mountain and Yanzhi Mountain. After completion, the scale of the station will be 2 stations and 4 lines.

The station is located in the foothills of the Qilian Mountains, with an altitude of more than 3,100 meters, and the natural environment is harsh. Since entering the construction site in March this year, the participating employees of China Railway 21st Bureau have overcome the difficulties of using soil to approve the problem, cold and heavy rain and snow, road slushing and mud, close to existing lines, and narrow construction sites. The construction design has been optimized and the construction period has been reversed. 24 hours of uninterrupted time and progress, successfully solved a series of problems such as the transportation of construction materials across the existing lines of the Lanzhou-Xinhua high-speed railway, steel structure shelters, and hoisting above the existing lines. All works such as canopy and passage.

The Lanxin High-speed Railway runs 22 pairs of trains every day. In order to ensure the safety of the existing line, they have built a 1,100-meter-high standard hard isolation facility to implement seamless monitoring and control of all operating procedures. Due to the small space, the nearest operating point is less than 2 meters from the lowest safety red line. They used manual and mechanical methods to transport the construction materials to the operating site many times to clear the materials after the work was completed, and achieved more than 70 "skylight points" operations with zero errors, Zero accidents, to ensure the normal and safe operation of existing railway trains.

During the construction process, the project strictly abides by the regulations on ecological and environmental protection, invites local ecological and environmental protection departments to conduct on-site publicity and education on ecological and environmental protection, and guides all participants in the construction to take care of the grassland, bushes and wild animals, and not to cross the grassland for half a step; signed with each work team Eco-environmental protection responsibility letter, all production and life are electrified, no open flames are eliminated, no dead spots are cleaned in the whole area of the work site every time before get off work, and the whole area of the work site is cleaned up. Standards promote ecological protection and construction of Shandan Racecourse Station. Editor/Xing Wentao
