Manufacturing Technology Research And Application Of Large-span Steel Box Girder

In bridge engineering field, to meet the use function and carrying therequirement of function, large span steel box girder is widely, this article takes thebig span steel box girder production process as the main ideas, this paperexpounds the design of the trestle structure, production technology of the steelbox girder; This paper focuses on the panel manufacturing process of the steel boxgirder, assembly process, welding technology, the whole assembly process andcoating process, emphasizes the production process measurement control andwelding deformation control measures, and summarized the manufacturingmethods of the large-span steel box girder.Based on the basic theory, in this paper, with the bigger space combined withHong Kong Stonecutter bridge, Zhanjiang bay bridge two engineering examples,expounds the production process of the large span steel box girder, and.described the specific measures of dimensional accuracy and weld distortioncontrol.
