Supporting latticed column in deep foundation pit and construction method
The invention relates to a supporting latticed column in a deep foundation pit and a construction method. The construction method comprises the following steps that after drilling, a straightening frame platform is fixed to the ground; hoisting and placing the steel latticed column; concrete pouring is conducted through concrete pouring holes of the concrete pouring platform, and a cast-in-place pile is formed; and basement structure construction is conducted. The invention has the following beneficial effects: the finalized latticed column bracket accurate positioning and adjusting technology is adopted, the bracket is detachable, simple and easy to straighten, the bracket straightening frame platform is fixed with the ground in a manner of planting expansion bolts after punching, and the latticed column is hung and placed through the limiting groove formed in the center of the straightening frame platform; the symmetrical adjustable screw rods mounted on the straightening frame platform are used for equidistant measurement for preliminary positioning, and finally the threaded rod is used for fine adjustment and fixation, so that the straightening precision is improved, and the perpendicularity and positioning are ensured to meet the design requirements.
本发明涉及一种深基坑内支撑格构柱及施工方法，包括以下步骤：钻孔后调直架平台与地面固定；吊放钢格构柱；利用混凝土浇筑平台的混凝土浇筑孔进行混凝土浇筑，形成灌注桩；进行地下室结构施工。本发明的有益效果是：采用定型化格构柱支架精确定位调整技术，该支架可拆且简单易调直，支架调直架平台采用打后植膨胀螺栓的方式与地面固定，通过调直架平台中心设有的限位槽吊放格构柱，并利用调直架平台上安装的对称可调螺杆等距测量进行初步定位，最后利用螺纹杆进行微调及固定，提高了调直精度，保证垂直度与定位满足设计要求。
