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.

Yicheng Lithium Energy Project in Qujing
The project is located in Nanhaizi Industrial Park, Qujing, Yunnan. The workshop is 256 meters long, 96 meters wide, and 21.7 meters high at the eaves. Our company is responsible for the fabrication, transportation, and installation of the steel structure in Zone I. The construction faces challenges such as high hoisting height and high roof hoisting risk. My team uses knuckle boom cranes and aerial work platforms to ensure the safety of high-altitude operations, and the roof adopts the process of assembling into large units on the ground and then hoisting them as a whole.

Steel bridge project of Jiaozi Peak Wind Farm in Panxian County, Guizhou Province
The project's bridge superstructure adopts a welded steel truss girder and rectangular hollow steel diagonal bracing design. The bridge is 32.0 meters long and 6.5 meters wide, with a structure including lower flanges, 8 webs, a top flange, and transverse stiffeners, forming a stable overall structure. The bridge has the capacity to bear a 130-ton heavy-duty trailer, spanning a valley, demonstrating its strong crossing ability. During the lifting process, due to geographical limitations, lifting operations could only be performed on one side. Therefore, the engineering team carefully planned and used a 300-ton truck crane in coordination with a 240-ton truck crane to ensure the smooth progress of the lifting work.
