Optimized erecting construction method for small-radius cast-in-place box girder plate buckle type full framing steel pipe support
The invention provides an optimized erecting construction method for a small-radius cast-in-place box girder plate buckle type full steel pipe support. The optimized erecting construction method comprises the following steps that construction preparation is conducted; foundation treatment, original ground ash mixing treatment and upper layer filling limestone soil layered rolling treatment are conducted; constructing a support foundation, mounting a template, pouring and vibrating concrete, and curing the concrete; the method comprises the steps of support erecting, positioning paying-off, bottom support installation, first-layer vertical rod installation, horizontal rod and inclined rod installation, sequential circulation installation and top support installation, and supports in the midspan or at the end of each span are disconnected in a V shape; the support is pre-pressed, and the pre-pressing load is not smaller than 120% of the total construction load; constructing a cast-in-place box girder; removing the bracket; the linear appearance requirement of the ramp cast-in-place box girder can be effectively met, and meanwhile it is guaranteed that the full steel pipe support is stable and safe.
本发明提供一种小半径现浇箱梁盘扣式满堂钢管支架优化搭设施工方法，包括以下步骤：施工准备；地基处理，原地面掺灰处理，上层填筑石灰土分层碾压处理；支架基础施工，模板安装，混凝土浇筑并振捣，混凝土养护；支架架设，定位放线，底托安装，首层立杆安装，水平杆斜杆安装，依次循环安装，顶托安装，其中每跨跨中或端部支架“V”型断开；支架预压，预压荷载不小于施工总荷载的120％；现浇箱梁施工；支架拆除；本发明能够有效保证匝道现浇箱梁的线形外观要求，同时保证满堂钢管支架稳定安全。
