Foundation pile foundation hole forming construction method
The invention discloses a foundation pile foundation hole-forming construction method which solves the technical problems that in the prior art, the efficiency of foundation pile foundation hole-forming construction is low, or the chambering effect of an expanded head in foundation pile foundation hole-forming is not ideal. The method comprises the following steps: step 1, arranging a site; step 2, surveying and setting out; thirdly, a drilling machine is in place; 4, drilling to form a hole; step 5, mounting a steel casing; sixthly, an expanded head is excavated; and step 7, pore-forming detection. The device is scientific and reasonable in design and convenient to operate, not only can rapidly construct and form holes to meet the construction progress, but also can efficiently clear pile bottom slag to rapidly finish hole pile expanded head reaming construction, and the expanded head reaming construction effect is good.
本发明公开了一种地基桩基础成孔施工方法，解决现有技术地基桩基础成孔施工效率低、或者地基桩基础成孔中扩大头扩孔效果不理想的技术问题。本发明包括以下步骤：步骤一、场地布置；步骤二、测量放样；步骤三、钻机就位；步骤四、钻进成孔；步骤五、钢护筒安装；步骤六、扩大头开挖；步骤七、成孔检测。本发明设计科学合理，操作方便，其既能快速施工成孔以满足施工进度，又能高效清除桩底成渣以快速完成孔桩扩大头扩孔施工，并且扩大头扩孔施工效果好。
