Asynchronous construction method for full-prefabricated assembled corrugated steel web bridge
The invention provides an asynchronous construction method for a full-prefabricated assembled corrugated steel web bridge. The method comprises the steps of firstly, completing cast-in-place construction of a 0 # section and a 1 # section, and firstly, hoisting and constructing a prefabricated corrugated steel web and a steel diaphragm plate of an N-1 # section; hoisting the prefabricated corrugated steel web and the steel diaphragm plate of the N # section to the bridge, hoisting the concrete prefabricated bottom plate of the N-1 # section to the lower part of the bridge, and constructing theconcrete prefabricated bottom plate of the N-1 # section, the prefabricated corrugated steel web and the steel diaphragm plate of the N # section; hoisting the prefabricated corrugated steel web of the N+1 # section, the concrete prefabricated bottom plate of the N # section and the steel diaphragm plate of the N+1 # section to the bridge at the same time, hoisting the concrete prefabricated topplate of the N-1 # section to the bridge, and repeating the steps to complete the construction of the cantilever section of the bridge; and finally, constructing the bridge deck, and completing wholebridge construction. Full-prefabricated asynchronous construction is adopted, the concrete quality is improved, the time of on-site high-altitude operation is shortened, and the engineering risk is reduced.
本发明公开了一种全预制拼装施工波形钢腹板桥异步施工方法，首先完成0#节段和1#节段现浇施工，首先吊装施工N‑1#节段的预制波形钢腹板和钢横隔板；之后吊装N#节段的预制波形钢腹板和钢横隔板至桥上的同时，吊装N‑1#节段的混凝土预制底板至桥下，同时进行N‑1#节段的混凝土预制底板、N#节段的预制波形钢腹板和钢横隔板施工；之后同时吊装施工N+1#节段的预制波形钢腹板、N#节段的混凝土预制底板和N+1#节段的钢横隔板至桥上的同时，吊装N‑1#节段的混凝土预制顶板至桥上，重复上述步骤，完成桥梁悬臂段施工；最后对桥面施工，完成整个桥梁施工。本发明采用全预制化异步施工，提高了混凝土质量，缩短现场高空作业的时间，减低工程风险。
