Hole-forming construction method suitable for slide-resistant pile percussion drill
The embodiment of the invention provides a hole-forming construction method suitable for a slide-resistant pile percussion drill, and belongs to the technical field of drilling. The hole-forming construction method comprises the following steps: providing a percussion drill; the percussion drill comprises a drill body and a drill bit, the drill bit is connected with the drill body through a steel wire rope and comprises a cross-shaped drill bit part and a reaming part arranged on the peripheral side of the drill bit part, the bottom of the drill bit part protrudes out of the bottom of a reaming hole, the reaming part is square, a plurality of percussion teeth are arranged on the peripheral side of the bottom of the reaming part, and the percussion teeth are provided with wedge-shaped faces. Construction preparation; surveying and setting out, and preparing mechanical equipment and a site; performing hole-forming construction; a percussion drill is in place and forms a square hole by adopting a steel wire rope percussion drilling ruler and a slurry direct circulation deslagging method; lowering a reinforcement cage, installing a guide pipe and pouring underwater concrete; and detecting the pile forming quality. The hole forming construction method suitable for the anti-sliding pile percussion drill can be suitable for drilling operation of anti-sliding square piles, safety is high, and the drilling efficiency is improved.
本申请实施例提供了一种适用于抗滑桩冲击钻的成孔施工方法，属于钻孔技术领域。成孔施工方法包括以下步骤：提供冲击钻机；冲击钻机包括钻机本体和钻头，钻头通过钢丝绳与钻机本体连接，钻头包括呈十字形的钻头部和设置于钻头部外周侧的扩孔部，钻头部的底部凸出于扩孔的底部设置，扩孔部为方形，扩孔部的底部周侧设置有若干冲击齿，冲击齿具有楔形面；施工准备；测量放线、机械设备和场地准备；成孔施工；冲击钻机就位，冲击钻机采用钢丝绳冲击钻进尺和泥浆正循环排渣方法成方形孔；钢筋笼下放、安装导管及水下混凝土浇筑；成桩质量检测。这种适用于抗滑桩冲击钻的成孔施工方法能够适用于抗滑方桩的钻孔作业，安全性高，提高钻孔效率。
