Mounting and positioning method and mounting structure of reverse construction method foundation pit steel stand column
The invention relates to the technical field of building foundation construction, in particular to an installing and positioning method for a reverse construction method foundation pit steel stand column. (3) mounting a reinforcement cage at the bottom of the pile hole; (4) pouring concrete at the bottom; (5) mounting a steel stand column: simultaneously performing perpendicularity control, elevation control and azimuth angle control on the steel stand column; and (6) taking out the positioning pile casing. The positioning pile casing is used for positioning and restraining the steel stand column, so that the perpendicularity, the elevation and the azimuth angle of the steel stand column can meet the design standard on the premise of quickly installing the steel stand column.
本发明涉及建筑基础施工技术领域，特别是涉及一种逆作法基坑钢立柱的安装定位方法，包括以下步骤：1）桩孔施工：2）在桩孔的顶部设置定位护筒：3）在桩孔的底部进行钢筋笼安装：4）底部混凝土浇筑：5）钢立柱安装：同时对钢立柱进行垂直度控制、标高控制和方位角控制：6）取出定位护筒。本发明中利用定位护筒对钢立柱进行定位约束，使得能在快速安装钢立柱的前提下保证钢立柱的垂直度、标高和方位角符合设计标准。
