The project is located in Longsheng Each Nationality Autonomous County, Guilin City, Guangxi Zhuang Autonomous Region. It uses a steel-concrete composite beam structure and spans the Gui-san Expressway and Heping River. The project steel plates are 30mm~70mm thick, with high welding requirements. Due to the large span of the composite beam, the installation accuracy of each segment is high during installation. The measurement work is strict and meticulous, controlling measurement errors, closely monitoring each process, optimizing the welding sequence and method of on-site circumferential welds, preparing corresponding contingency plans for weld inspection and rework of the entire welding project, and ensuring that the finished composite beam meets the design and specification requirements.
