Synchronous drilling and excavating rectangular anti-slide pile mechanical hole forming method with haunched horizontal cantilever
The invention discloses a synchronous drilling and excavating rectangular anti-slide pile mechanical hole forming method with a haunched horizontal cantilever, which comprises the following steps that a slag body processing mechanism, a sliding horizontal drilling assembly and a vertical drilling device are sequentially arranged on a drilling machine from top to bottom, and the sliding horizontal drilling assembly is magnetically attracted to the vertical drilling device; a cylindrical drill assembly on the vertical drilling device is controlled to drill and excavate the stratum downwards till the designed depth of the haunching hole is reached; a horizontal hydraulic cylinder is controlled to drive a cylindrical drill assembly on a horizontal drill device to drill haunching holes in the side portion of the rectangular pile hole; the vertical drilling device and the sliding horizontal drilling assembly are disconnected, and the horizontal hydraulic cylinder is continuously controlled to drive a cylindrical drilling assembly on the horizontal drilling device to drill the horizontal cantilever pile hole outwards; and a piston rod of the horizontal hydraulic cylinder retracts to the minimum stroke and stops working, the sliding horizontal drilling assembly moves downwards under the self weight of the sliding horizontal drilling assembly and is magnetically attracted to the vertical drilling device, and the cylindrical drilling assembly on the vertical drilling device continues to be controlled to drill the stratum downwards to the designed depth of the rectangular pile hole.
本发明公开了一种同步式钻挖带加腋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、滑动水平钻组件以及竖向钻装置，滑动水平钻组件磁吸于竖向钻装置；控制竖向钻装置上的圆柱钻组件向下钻挖地层直至加腋孔的设计深度；控制水平液压缸驱动水平钻装置上的圆柱钻组件向矩形桩孔的侧部钻挖加腋孔；断开竖向钻装置和滑动水平钻组件之间的连接，继续控制水平液压缸驱动水平钻装置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，滑动水平钻组件在其自重下向下移动并磁吸于竖向钻装置，继续控制竖向钻装置上的圆柱钻组件向下钻挖地层至矩形桩孔的设计深度。
