Longcheng Bridge, Guangxi

Longcheng Bridge, Guangxi

The project is located in Longsheng Each Nationality Autonomous County, Guilin City, Guangxi Zhuang Autonomous Region. It adopts a steel-concrete composite beam structure and is built to span the GuiSan Expressway and Heping River. The project uses steel plates with a thickness of 30mm~70mm, and the welding seams have high 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, and preparing contingency plans for weld inspection and rework of the entire welding project to ensure that the finished composite beam meets the design and specification requirements.
