Construction method of cast-in-situ bored pile penetrating through underground structure
The invention belongs to the technical field of building construction, and particularly relates to a construction method of a cast-in-situ bored pile penetrating through an underground structure, comprising a crawler chassis, a turntable, a first hydraulic cylinder, a mounting arm and a support column; a rotating disc is rotatably mounted on the top surface of the crawler chassis, a plurality of first hydraulic cylinders are uniformly mounted on the top surface of the rotating disc in a surrounding manner, mounting arms are mounted at the ends of piston rods of the first hydraulic cylinders, and a plurality of supporting columns are slidably mounted in the middles of the mounting arms; the crawler chassis is controlled to move into the existing structure, the first hydraulic cylinder steel pushes the mounting arms to be unfolded outwards, and the multiple supporting columns are fixedly connected end to end and mounted in the middles of the mounting arms; an existing structure is supported through the multiple supporting columns, during drilling, only a first hydraulic cylinder needs to be rotated, the supporting positions of the supporting columns are changed, and the dismounting difficulty of workers is lowered; and after construction is completed, the crawler chassis is controlled to conduct transition, and the working efficiency of workers is improved.
本发明属于建筑施工技术领域，具体的说是一种穿透地下构筑物的钻孔灌注桩施工方法，包括履带底盘、转盘、一号液压缸、安装臂和支撑柱；所述履带底盘的顶面转动安装有转盘，所述转盘的顶面均匀环绕安装有多个一号液压缸，所述一号液压缸的活塞杆端头安装有安装臂，所述安装臂的中部滑动安装有多个支撑柱；操控履带底盘移动到既有结构的内部，一号液压缸钢推动安装臂向外侧展开，将多个支撑柱首尾连接固定，并安装到安装臂的中部；通过多个支撑柱对既有结构进行支撑，当进行钻孔时，只需转动一号液压缸，改变支撑柱的支撑位置，降低了工作人员拆卸的困难度；待施工完成后，控制履带底盘进行转场，提高了工作人员的工作效率。
