Cantilever bent cap construction method
The invention belongs to the field of beam bridge construction, and provides a cantilever cover beam construction method which comprises the following steps: pouring a prefabricated foundation and a full framing foundation by using concrete; a support body is erected according to the foundation position of the full framing, and a longitudinal beam support is installed; the support body and the longitudinal beam support are pre-pressed through steel bars, and then the support body and the longitudinal beam support are adjusted; a truss is built on the bottom die of the longitudinal beam support after adjustment is completed; after the truss is built, a bent cap body is laid on the truss body and the longitudinal beam support through steel bars; after the capping beam body is laid, steel beam prestress tensioning and pipeline installation and reinforcement are conducted; after the pipeline is installed, the capping beam body and the pipeline are subjected to grouting and compacting treatment through structural concrete; a side formwork is installed according to the size of a bent cap body after grouting and compacting treatment; after the side formworks are installed, concrete is poured to form a bent cap; and after the bent cap is formed, the supports and the side molds are detached. The problems that materials are wasted and the construction efficiency is low during cantilever bent cap construction are solved.
本发明属于梁桥施工领域，提供了一种悬臂盖梁施工方法，所述悬臂盖梁施工方法包括以下步骤:用混凝土浇筑预制基础、满堂支架基础；根据满堂支架基础位置进行支架架体搭设、纵梁支架的安装；采用钢筋对支架架体以及纵梁支架进行预压，之后调整架体以及纵梁支架；调整完成在纵梁支架的底模上搭建桁架；桁架搭建后，在架体和纵梁支架采用钢筋进行铺设盖梁主体；盖梁主体铺设完进行钢束预应力张拉以及管道安装及加固；管道安装完成后对盖梁主体和管道用结构混凝土压浆密实处理；压浆密实处理后根据盖梁主体尺寸进行安装侧模；侧模安装后用混凝土浇筑形成盖梁；盖梁形成后，拆除支架和侧模。本发明解决了悬臂盖梁施工浪费材料、施工效率低的问题。
