Beijing Zhangjiakou High Speed Railway: fine and span over 1mm
Shijiazhuang, Dec. 30, Xinhua News Agency (reporter Qin Jing, Wang Kun) on Dec. 30, the first intelligent high-speed railway and Zhangjiakou high-speed railway station, the "gateway project" of 2022 Winter Olympic Games, were officially opened to traffic. It marks that the construction of China's first "intelligent" high-speed railway has entered a new stage, and this century old railway will bear a new historical mission.
"Beijing Zhangjiakou Railway is the starting point for Chinese people to independently design and build railway. Without this starting point, we can't stand on the "shoulder" of rapid development of China's railway, equipment manufacturing and comprehensive national strength, and plan the fine and leaping of China's high-speed rail on the "1mm" Wang Hongyu, general design director of Beijing Zhangjiakou high speed railway of China Railway Design Group, said.
China Railway Design Group undertakes the survey and design task of the whole line of Beijing Zhangjiakou high speed railway. The total length of the new main line of Beijing Zhangjiakou high speed railway is 173.947km. 70.42km in Beijing and 103.527km in Hebei. In addition to the existing Beijing North Station, there are 8 stations in the whole line, including Qinghe, Changping, Badaling, donghuayuan, Huailai, Xiahuayuan north, Xuanhua and Zhangjiakou. Chongli railway is connected from Beijing Zhangjiakou high-speed railway to Huayuan north station, which is generally north-south trend, and then to taizicheng village to set taizicheng station.
"we have been working on the preliminary work for seven years. The design materials are piled up to the height of one floor, which is four times the design amount of other Railways of the same length." Wang Hongyu said. The
Beijing Zhangjiakou Railway is a high-speed railway with a design speed of 350 kilometers per hour. The development and use of ballastless track bridge construction is also the most advanced intelligent track technology in the world. The error between the track and the track is only allowed to be 2 mm. Jiang Weiping, deputy general manager of
China Railway Design Group, said that Beijing Zhangjiakou high speed railway has ushered in a new era of Intelligent Railway Construction in China, with major breakthroughs in automatic train driving, intelligent dispatching and command, intelligent fault diagnosis, building information model, Beidou satellite navigation, biometric identification, etc.
