Hole-forming method for reaming synchronous drilling and digging rectangular anti-slide pile with haunched horizontal cantilever
The invention discloses a hole-forming method for a hole-reaming synchronous drilling and digging rectangular anti-slide pile with a haunched horizontal cantilever, which comprises the following steps of: combining a plurality of drilling machines to form a rectangular structure corresponding to the size of a rectangular pile hole; vertical drilling devices on all the drilling machines are controlled to drill and excavate the stratum downwards to the designed depth of the haunching hole; a horizontal hydraulic cylinder on a drilling machine arranged close to the haunching hole and horizontal cantilever pile hole excavation part is controlled to drive a cylindrical drill assembly on a horizontal drilling device to drill and excavate the haunching hole towards the side part of the rectangular pile hole; the horizontal hydraulic cylinder is continuously controlled to drive the horizontal drilling device to drill the horizontal cantilever pile hole outwards; meanwhile, the vertical drilling devices on all the drilling machines are continuously controlled to drill and dig the stratum downwards; and the piston rod of the horizontal hydraulic cylinder retracts to the minimum stroke and stops working, and the vertical drilling devices on all the drilling machines continue to be controlled to drill the stratum downwards to the designed depth of the rectangular pile hole. The rectangular anti-slide pile drilling machine has the advantages that according to different sizes of rectangular pile holes, a corresponding number of drilling machines forming a rectangular structure are arranged on the rectangular anti-slide pile drilling machine so as to drill and dig the rectangular pile holes.
本发明公开了一种可扩孔同步式钻挖带加腋水平悬臂的矩形抗滑桩成孔方法，包括：将多个钻机组合，形成同矩形桩孔尺寸相对应矩形结构；控制所有钻机上竖向钻装置向下钻挖地层至加腋孔设计深度；控制靠近加腋孔和水平悬臂桩孔开挖部设置的钻机上水平液压缸驱动水平钻装置上圆柱钻组件向矩形桩孔侧部钻挖加腋孔；继续控制水平液压缸驱动水平钻装置向外钻挖水平悬臂桩孔；同时继续控制所有钻机上竖向钻装置向下钻挖地层；使水平液压缸的活塞杆回缩至最小行程并停止工作，继续控制所有钻机上竖向钻装置向下钻挖地层至矩形桩孔设计深度。本发明的优点是：根据矩形桩孔的不同尺寸，在矩形抗滑桩钻机上设置对应数量并形成矩形结构的钻机，以钻挖矩形桩孔。
