On May 17, 2022, the construction of the first pile foundation of the Bao (Head) Yin (Chuan) High-speed Railway Cross-Hai Letaisigou Bridge undertaken by China Railway Shanghai Engineering Bureau began, which means that the main project of the Bao-Yin High-speed Railway Inner Mongolia section has entered the construction stage .

Baoyin High-speed Railway Inner Mongolia Section

According to reports, the Inner Mongolia section of the Baoyin high-speed railway is 402 kilometers long and has a design speed of 250 kilometers per hour. The Baoyin High-speed Railway No. 1 bid constructed by China Railway Shanghai Engineering Bureau is located in Baotou City and Bayannaoer City, Inner Mongolia. The main line has a total length of 57.37 kilometers and is mainly responsible for 36.67 kilometers of roadbed, 18 bridges, and 4.7 kilometers of reconstruction of the main line track laying and Baiyanhua West Station. Construction tasks such as house renovations.

Hu Yahui, project manager of Baoyin Railway Fourth Branch of China Railway Shanghai Engineering Bureau, introduced that the Baoyin High-speed Railway Cross-Hale Taisigou Bridge has a total length of 2572.4 meters and a total of 752 bored piles, 80 caps and 78 pier bodies. Bayannaoer, where the bridge is located, is windy and sandy, with little precipitation and a large temperature difference between day and night, which brought great challenges to the construction of the project. In order to ensure the smooth drilling of the first pile, the project department carefully organized and worked hard to overcome unfavorable factors such as epidemic prevention and control, land acquisition and demolition, and limited access to materials, and quickly promoted the construction of large-scale projects such as the central laboratory, concrete mixing plant, and steel bar processing plant. Successfully passed the acceptance, laying a solid foundation for the substantial start of the main project.

The Baoyin High-speed Railway (including the Ba-Yin branch line) is an important part of the national eight vertical and eight horizontal high-speed railway Jing-Lanzhou Corridor. . In the future, after the project is completed, it will strongly support Inner Mongolia's service and integration into the new development pattern, and will strongly support the smooth flow of east and west China and the connection between north and south.
