The project is located in Nancun Town, Pingdu City, Qingdao, involving structural components with single-unit lengths of approximately 27.2 meters. It encompasses the fabrication of high-complexity elements such as 26-ton double-shoulder components, four-corbel assemblies, and ultra-tall lattice columns with aircraft nose-inspired configurations. Key processes and techniques employed include rust removal for extra-wide plates (road/bridge panel shot blasting) and intricate edges (laser cleaning), oversized material cutting, medium-thick plate splicing, manual assembly welding for super-sized components, heavy lifting and positioning, vertical and overhead welding operations, as well as precision testing and measurement throughout the construction phase.
