Column bottom embedded steel pipe pile positioning construction method
The invention provides a column bottom embedded steel pipe pile positioning construction method. The positioning construction method comprises the following steps that 1, a foundation pile hole is constructed and concrete is poured to form a primary concrete layer; 2, a reinforcing mesh layer and a foundation bolt positioner are installed, the foundation bolt positioner comprises a positioning ring plate, a positioning column and a plurality of bolt connecting pieces, so that the bottom surface of the foundation bolt is positioned 0.2-0.5 meter above a primary concrete layer; 3, the foundation bolts are positioned and adjusted, and then the concrete is poured into the foundation pile hole to form a secondary concrete layer; 4, a bearing platform is excavated to form a bearing platform construction position; 5, the steel pipe pile foundation bolt positioner is dismantled, and the foundation bolts are reserved and pre-buried in the secondary concrete layer; 6, a steel pipe column is installed; and 7, the bearing platform is constructed. According to the column bottom embedded steel pipe pile positioning construction method, pre-burying construction of the foundation bolt group on a concrete foundation can be efficiently, integrally and accurately achieved, and rapid, efficient and accurate pre-burying construction of the foundation bolt group in the foundation pile hole can be achieved.
本发明提出一种柱底内埋式钢管桩定位施工方法，其步骤有：1、施工基础桩孔及浇筑混凝土形成一次混凝土层；2、安装钢筋网片层及地脚螺栓定位器；地脚螺栓定位器包括有定位环板、定位柱和若干组螺栓连接件，使地脚螺栓的底面位于一次混凝土层上方0.2至0.5米；3、定位调整地脚螺栓，之后在基础桩孔内浇筑混凝土形成二次混凝土层；4、承台开挖形成承台施工位；5、拆除钢管桩地脚螺栓定位器，留下地脚螺栓预埋于二次混凝土层内；6、安装钢管柱；7、施工承台。本发明能高效、整体和精准的实现地脚螺栓群在混凝土基础上的预埋施工，以及在基础桩孔内实现地脚螺栓群的快速、高效和精准的预埋施工。
