Cast-in-place pile construction method
The invention relates to a cast-in-place pile construction method which is applied to the field of cast-in-place pile construction. The method comprises the following steps: a positioning step: carrying out survey lofting in a leveled site, and marking the position of a hole to be drilled; drilling is conducted, specifically, a drilling assembly is driven to rotate and move downwards at the same time, and an initial pile hole is drilled; a hole expanding step: reversing the drilling assembly at the bottom of the primary pile hole, releasing a hole expanding assembly in the drilling assembly, abutting against the inner wall of the primary pile hole, and extruding the inner wall of the primary pile hole to form a dense protective layer so as to form a final pile hole; a reinforcement cage lowering step: after the protective layer is formed, the reinforcement cage is lowered into the final pile hole, so that the reinforcement cage is uniformly distributed in the final pile hole; and in the pouring step, concrete is poured into the final pile hole, and the cast-in-place pile is formed after the concrete is solidified. The method has the effect of reducing the possibility of hole collapse.
本申请涉及一种灌注桩施工方法，应用在灌注桩施工的领域。其包括定位步骤，在平整后的场地中进行测量放样，标记待钻孔的位置；钻孔步骤，驱动钻进组件转动的同时向下移动，钻出初桩孔；扩孔步骤，钻进组件在初桩孔的底部反转，释放钻进组件内部的扩孔组件，与初桩孔的内壁抵贴，挤压初桩孔的内壁形成密实的保护层以形成终桩孔；下钢筋笼步骤，形成保护层后将钢筋笼下放至终桩孔内，使得钢筋笼均布于终桩孔内；浇筑步骤，向终桩孔内浇筑混凝土，待混凝土固化后即形成灌注桩。本申请具有降低了坍孔的可能性的效果。
