The Chayouqian Banner Extra Large Bridge is located in Ulanqab City, Inner Mongolia. The Zhangjiakou to Hohhot section of the Beijing Baotou Railway runs nearly 70 high-speed trains and multiple units per day, making it an important passage connecting Inner Mongolia to the Beijing Tianjin Hebei region.
The total weight of the four box girders erected this time is 356 tons, which is characterized by tight construction time and high safety risks. In order to ensure the smooth completion of the beam erection for the existing Beijing Baotou Passenger Dedicated Line, the construction unit advanced planning and scientific organization, carefully studied the construction plan and safety technology plan of the business line, and invested more than 300 construction personnel and more than 40 large-scale construction equipment to ensure the safe and orderly implementation of the beam transportation and erection plan.
The Jidayuan High speed Railway is an important component of the national "Eight Verticals and Eight Horizontals" high-speed railway network, which is the Hohhot South Passage. It starts from Ulanqab Station of the Zhanghu High speed Railway in the north and connects to Yuanping West Station of the Daxi High speed Railway in the south, with a newly built line of about 270 kilometers and a designed speed of 250 kilometers per hour.
The completion of this high-speed rail will be of great significance in helping Inner Mongolia integrate into the national high-speed rail network and accelerating the coordinated development of Inner Mongolia, Shanxi, and the Beijing Tianjin Hebei region.
