Corrugated steel web cast-in-place cantilever box girder closure section construction method
The invention belongs to the technical field of bridge closure section construction, and particularly relates to a corrugated steel web cast-in-place cantilever box girder closure section construction method. Comprising the following steps that 1, concrete top plates of N-1 sections on the two sides of a bridge closure section are constructed; and 2, closure section construction is conducted, wherein N sections of steel webs, N sections of concrete bottom plates and N sections of concrete top plates are sequentially installed. According to the technical scheme, through stress analysis of an existing rigid frame bridge structure of a corrugated steel web cast-in-place cantilever box girder in the construction process, it is found that in the construction process of a closure section in the existing construction process, the corrugated steel web of the structure can be directly adopted to replace a stiff framework added through construction measures, and practice proves that the corrugated steel web of the structure can be used for replacing the stiff framework added through the construction measures. According to the construction method, on one hand, the cost input of closure section construction is greatly reduced, on the other hand, the construction process is simplified, and the construction progress of the bridge is further accelerated. And a practical basis is provided for construction of the same type of bridge closure sections.
本发明属于桥梁合拢段施工技术领域，特别涉及一种波形钢腹板现浇悬臂箱梁合拢段施工方法。包括以下步骤：步骤1：进行桥梁合拢段两侧N‑1节段砼顶板施工；步骤2：合拢段施工，包括依次进行的N节段钢腹板安装、N节段砼底板安装和N节段砼顶板安装。本发明的技术方案中，通过对现有的波形钢腹板现浇悬臂箱梁的刚构桥结构在施工过程中的受力分析，发现现有施工过程中在合拢段的施工过程中，可以直接采用结构自有波形钢腹板取代施工措施增加的劲性骨架的功能，通过实践证明，该种施工方法一方面极大的降低了合拢段施工的成本投入，另一方面，简化了施工过程，进一步的加快了桥梁的施工进程。对于同类型的桥梁合拢段施工提供了实践依据。
