The successful rotation of the main bridge of the Weihe Grand Bridge has reached a maximum rotation height of 50.9 meters, ranking first among similar bridges nationwide, fully demonstrating China's leading position in the field of bridge rotation technology. During the rotation process, an intelligent monitoring system was used to track and monitor various data in real time, achieving dynamic adjustment of parameters such as rotation speed, posture, and angle, ensuring precise docking of the rotation. The application of this technology not only improves construction efficiency, but also greatly reduces construction risks, setting a new benchmark for the development of bridge construction technology in China.

The main bridge of the Weihe River Grand Bridge, as a controlling project of the Tianzhuang Expressway, is extremely difficult to construct. The bridge piers are relatively high, and the rotating T-shaped structure is prone to longitudinal and transverse imbalances, making the construction technology complex. To ensure the success of the rotation, the participating units actively explore and apply new technologies, organize the research and development of visual modeling and intelligent monitoring system for the rotation construction of bridges, achieve "balance control" and "intelligent traction" of high pier rotation, and realize automatic monitoring and control of construction. These efforts not only overcame technical difficulties during construction, but also provided valuable experience for similar projects in the future.

The Tianzhuang Expressway is an important transportation artery in Gansu Province, and its construction is of great significance for improving the road network in eastern Gansu and promoting regional development. As a key node of the project, the successful rotation of the Weihe Grand Bridge not only laid a solid foundation for the subsequent construction of the project, but also provided strong support for the full operation of the Tianzhuang Expressway by the end of the year. After its opening, it will end the history of Zhangjiachuan County and Qingshui County not being connected to highways, greatly improve local transportation conditions, promote regional economic development and social progress.
