Hole-forming construction method for large-diameter pile foundation
The invention provides a large-diameter pile foundation hole-forming construction method. The large-diameter pile foundation hole-forming construction method comprises the following steps that S1, the position of a to-be-formed pile foundation is determined; s2, drilling is carried out in multiple times along the central axis of the pile foundation, the diameters of drill bits adopted in each time of drilling are different, and the diameter of the drill bit adopted in the previous time of drilling is smaller than that of the drill bit adopted in the next time of drilling; and S3, a pile hole of the pile foundation is formed through drilling for the last time. By means of the method, the problem that the hole forming efficiency of a large-diameter pile foundation is low is effectively solved for areas with poor soil texture or hard rocks.
本发明提供了一种大直径桩基成孔施工方法，包括以下步骤：S1：确定待形成的桩基的位置；S2：沿所述桩基的中轴线，分次钻凿，每次钻凿采用的钻头的直径不同，前一次钻凿采用的钻头的直径小于后一次钻凿采用的钻头的直径；S3：最后一次钻凿形成所述桩基的桩孔。利用上述方法对于土质较差或硬岩为主地区，有效解决了大直径桩基成孔效率较低的问题。
