| Abstract: | Jinghang Cross-canal Bridge is a single-hole arch-steel-tube bridge which has a 132-meter long-span For the purpose of optimizing the installation work of steel pipe arch, according to such characteristics as the long span truss of the steel pipe arch, and through comparing two feasible plans of the steel pipe arch installation, this article draws a conclusion that the steel pipe arch installation plan of Jinghang Bridge is the arch type of aircraft hoisting. Also it discusses the specific implementation process of Cross-canal the plan and the major technical construction solutions to the steel tube temporary pier design and installation as well as the arch rib hoisting, and so on. |
