Arch bridge encased concrete bottom plate formwork installation method and bottom plate formwork thereof
The invention relates to the technical field of arch bridge encased concrete construction, in particular to an arch bridge encased concrete bottom plate formwork installation method and a bottom plate formwork thereof.The installation method comprises the steps that before stiff framework segments are hoisted, bottom formwork standard units and bottom formwork inlaying units are prepared; stiff skeleton sections are arranged in a heightening mode; bottom die standard units are installed, inlaying spaces are formed at the two longitudinal ends of the bottoms of the stiff framework sections, and operation platforms are formed on the two transverse sides of the stiff framework sections; hoisting the stiff skeleton section to a construction position to be connected with the skewback or a previous stiff skeleton section; after the arch ribs are closed, the bottom die inlaying unit is hoisted and installed, and through cooperation of ground installation and on-arch installation, formwork installation linear control is achieved, the construction progress is accelerated, and construction safety is ensured. According to the bottom die template, the force applied to the bottom die by bottom plate concrete pouring is effectively transmitted to the stiff framework, the mounting stability is good, the mounting precision is high, and the overall linear quality of a formed arch bridge is improved.
本发明涉及拱桥外包混凝土施工技术领域，特别涉及一种拱桥外包混凝土底板模板安装方法及其底板模板，该安装方法包括于劲性骨架节段吊装前，制备底模标准单元和底模嵌补单元；垫高设置劲性骨架节段；安装底模标准单元，在劲性骨架节段底部纵向两端形成嵌补空间，在劲性骨架节段横向两侧形成作业平台；吊运劲性骨架节段至施工位置与拱座或前一已安装劲性骨架节段进行连接；于拱肋合龙后，吊运安装底模嵌补单元，通过地面安装和拱上安装配合，实现模板安装线型控制，加快施工进度，确保施工安全。该底模模板将底板混凝土浇筑施加至底模的力有效传递至劲性骨架，安装稳定性好、安装精度较高，提高成型拱桥整体线型质量。
