In-pile guide hole auxiliary pile-forming construction method for large-diameter pipe pile
The invention discloses an in-pile guide hole auxiliary pile-forming construction method for a large-diameter pipe pile, and relates to the technical field of large-diameter pipe pile construction. The construction method comprises the following construction steps: assembling and debugging a spiral drilling machine, setting out construction and positioning a pile position and an elevation, rechecking by related personnel, checking and accepting the axis of a building, positioning a pile, positioning the spiral drilling machine in place, aligning a drill rod with the pile position, adjusting the perpendicularity of the drill rod, starting a motor to drill a hole, transporting taken-out clay to the outside of a field, measuring the hole depth, recording, pre-burying and positioning the pipe pile and mounting a protective sleeve. The method has the effect of reducing the risk of deformation and dislocation of the pile body.
本发明公开了一种大直径管桩桩内引孔辅助成桩施工方法，涉及大直径管桩施工的技术领域，其施工步骤包括：螺旋钻机组装调试、施工放线定位桩位及高程、相关人员复核、验收建筑物轴线、桩定位、螺旋钻机就位、钻杆对正桩位、调整钻杆垂直度、开动电机钻孔、运输取出的粘土至场外、测量孔深、记录备案、预埋并定位管桩和安装护套筒。本发明具有降低桩体变形和错位的风险的作用。
