Cast-in-place pile construction method
A cast-in-place pile construction method comprises the following steps that (1) a cast-in-place pile drilling machine is assembled; 2) debugging and operating a cast-in-place pile drilling machine; (3) the cast-in-place pile drilling machine rotates and drills downwards; (4) stirring and grouting by a cast-in-place pile drilling machine; and 5) standing and curing the cast-in-place pile to form the pile. The cast-in-place pile construction method has the advantages of being convenient to construct, low in equipment net height, flexible to move, convenient to install, high in operation efficiency and the like, connection between drill rods and drill bits and connection between the drill rods are reliable, disassembly is convenient, the drill bits at the front end of a drilling machine and alloy tool bits on inclined rods can conduct drilling and stirring at the same time, and meanwhile a lower circular ring on the drill bits can effectively protect the hole wall; the hole forming quality of the cast-in-place pile is guaranteed, the construction requirements of low clearance areas with limited height and close to surrounding buildings are met, and the construction efficiency of the cast-in-place pile is effectively improved.
一种灌注桩施工方法，包括以下步骤：1）灌注桩钻机组装；2）灌注桩钻机调试运行；3）灌注桩钻机旋转下钻；4）灌注桩钻机搅拌注浆；5）灌注桩静置养护成桩。本发明灌注桩施工方法具有施工方便、设备净高度低、移动灵活、安装方便和作业效率高等特点，钻杆与钻头、钻杆与钻杆之间连接可靠、拆解方便，实现钻机前端钻头和斜杆上的合金刀头同时钻进搅拌，同时钻头上的下圆环可对孔壁有效保护，保证灌注桩成孔质量，满足高度受限、临近周围建筑的低净空区域的施工需要，有效提高灌注桩施工效率。
