Rapid and safe construction method of river-crossing support cast-in-place arched girder
The invention discloses a rapid and safe construction method for a river-crossing support cast-in-place arched beam. The rapid and safe construction method comprises the following steps that firstly, a pier column foundation and an abutment body channel frame are constructed; secondly, a main arch support is erected; thirdly, a formwork is installed on the main arch support, and steel bars are bound and installed on the main arch support; fourthly, main arch concrete is poured and maintained, and when the strength of the concrete reaches 85%, a main arch closure section and an arch foot interval groove are constructed; 5, main arch supports below the web arch are reserved, other main arch supports are removed, web arch supports are erected at set positions on the main arch, and corresponding formworks and steel bars are installed; sixthly, web arch concrete is poured and maintained, when the concrete strength reaches 85%, a web arch closure section is constructed, and when the concrete strength reaches 100%, the full-bridge support is dismantled; seventhly, side walls on the main arch and the web arch are constructed, arch filler is backfilled, and bridge deck construction is completed in sequence. The construction process is reasonably arranged, and rapid and safe construction is achieved.
本发明公开了一种跨河支架现浇拱梁的快速安全施工方法，包括如下步骤：步骤一、进行墩柱基础以及台身通道框架施工；步骤二、搭设主拱支架；步骤三、在主拱支架上安装模板并绑扎安装钢筋；步骤四、进行主拱混凝土的浇筑并养护，待混凝土强度达到85％，施工主拱合拢段及拱脚间隔槽；步骤五、保留腹拱下方的主拱支架，其余主拱支架拆除，在主拱上的设定位置搭设腹拱支架，并安装对应的模板及钢筋；步骤六、浇筑腹拱混凝土并养护，待混凝土强度达到85％，施工腹拱合拢段，待混凝土强度达到100％时，拆除全桥支架；步骤七、施工主拱及腹拱上的侧墙并回填拱上填料，依次完成桥面施工。本发明对施工流程的合理安排，实现快速安全施工。
