html On May 7, the first pair of cable-stayed baskets of the Hanjiang River Bridge in the Hubei section of the West-10 High-Speed Railway were installed in place, marking that the cable-stayed bridge with the largest span beam and truss composite structure in China has entered the main girder cantilever construction stage.

This bridge stands beside the Han River, like a bridge in the sky. Many people praised it: Another Internet celebrity bridge appeared in Hubei.

The Xishi High-speed Railway starts from Xi'an, Shaanxi Province in the west, crosses the Qinling Mountains in the southeast, passes through Shangluo, and ends in Shiyan, Hubei Province. The main line is 255.76 kilometers long, of which 86.36 kilometers are in Hubei Province and 169.4 kilometers are in Shaanxi Province. The design speed is 350 kilometers per hour.

After the West 10th High-speed Railway is completed and opened to traffic, it will form a convenient high-speed rail channel between Xi'an and Wuhan. It will be important for the implementation of national development strategies such as the "Yangtze River Economic Belt" and "Western Development" and the construction of the "One Belt and One Road", and strengthen the connection between the Guanzhong Plain urban agglomeration and the Yangtze River. The connection between the central urban agglomerations is of great significance.

The proportion of bridges and tunnels in the Hubei section of the West 10 High-speed Railway is 98.85%. The geological conditions are complex and the construction safety risks are high. Moreover, many drinking water source protection areas in the Han River Basin and the Yunyang National Geological Park are involved along the line. In terms of environmental protection and water conservation, etc. It puts forward extremely high requirements for construction.

The Hanjiang River Bridge has a total length of 917.45 meters. The heights of the two main towers P3 and P4 are both 186.5 meters. It has a total of 80 pairs of cable-stayed cables and a main span of 420 meters. It is currently the largest span beam-truss composite structure cable-stayed bridge in China.

The total weight of the rope hanging basket installed this time is about 400 tons. The installation of the hanging basket adopts the construction concept of low-level assembly, overall lifting, and backward movement into place. It is first assembled on the construction platform, and then slowly lifted by a hydraulic jack for about 60 meters before anchoring.

The construction team overcame the difficulties of a small construction site and complex installation processes, and adopted a unit-by-unit installation method using tower cranes to ensure that safety and quality can be effectively controlled in every process. At the same time, the digital management and control center and the information-based smart construction site platform are used to integrate the AI video surveillance system, tower crane hook visualization system, temporary structure safety monitoring system and other subsystems to realize the "intelligent" management of hanging baskets and provide the basis for the subsequent 10 The foundation is laid for the construction of the 3-meter-long rope hanging basket.
