Mechanical hole forming method for drilling and excavating rectangular anti-slide pile with horizontal cantilever
The invention discloses a mechanical hole forming method for drilling and excavating a rectangular anti-slide pile with a horizontal cantilever. The mechanical hole forming method comprises the following steps that a slag treatment mechanism and a multifunctional drilling assembly are sequentially arranged on a drilling machine from top to bottom; a cylindrical drill assembly on the horizontal plane in the multifunctional drill assembly is controlled to drill and excavate the stratum downwards till the designed depth of the horizontal cantilever pile hole is reached; a cylindrical drill assembly on the vertical face and a horizontal hydraulic cylinder in the multifunctional drill assembly are started, and the cylindrical drill assemblies on the vertical face and the horizontal face in the multifunctional drill assembly drill haunching holes towards the side portion of the rectangular pile hole; a horizontal hydraulic cylinder is controlled to drive a cylindrical drill assembly on the vertical face in the multifunctional drill assembly to drill a horizontal cantilever pile hole outwards; and a piston rod of the horizontal hydraulic cylinder retracts to the minimum stroke and stops working, a cylindrical drill assembly on the horizontal plane in the multifunctional drill assembly is started, and the cylindrical drill assembly on the horizontal plane in the multifunctional drill assembly continues to be controlled to vertically drill the stratum downwards to the designed depth of the rectangular pile hole so as to form a built-in section of the rectangular pile hole.
本发明公开了一种钻挖带水平悬臂的矩形抗滑桩机械成孔方法，包括以下步骤：在钻机上自上而下依次设置渣体处理机构和多功能钻组件；控制多功能钻组件中在水平面上的圆柱钻组件向下钻挖地层直至水平悬臂桩孔的设计深度；开启多功能钻组件中在竖向面上的圆柱钻组件以及水平液压缸，多功能钻组件中在竖向面和水平面上的圆柱钻组件向矩形桩孔的侧部钻挖加腋孔；控制水平液压缸驱动多功能钻组件中在竖向面上的圆柱钻组件向外钻挖水平悬臂桩孔；使水平液压缸的活塞杆回缩至最小行程并停止工作，开启多功能钻组件中在水平面上的圆柱钻组件，继续控制多功能钻组件中在水平面上的圆柱钻组件竖直向下钻挖地层至矩形桩孔的设计深度以形成矩形桩孔的嵌固段。
