Synchronous drilling and excavating rectangular anti-slide pile mechanical hole forming method with horizontal cantilever
The invention discloses a synchronous drilling and excavating rectangular anti-slide pile mechanical hole forming method with a horizontal cantilever, which comprises the following steps: 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 positioned at the top of the vertical drilling device and moves up and down along the vertical direction; a cylindrical drill assembly on the vertical drilling device is controlled to drill the stratum downwards till the designed depth of the horizontal cantilever pile hole, and a free section of the rectangular pile hole is formed; after the sliding horizontal drilling assembly reaches the designed elevation of the bottom of the horizontal cantilever pile hole, a horizontal hydraulic cylinder is controlled to drive a cylindrical drilling assembly on a horizontal drilling device to drill the horizontal cantilever pile hole outwards; meanwhile, a cylindrical drill assembly on the vertical drilling device continues to be controlled to drill and dig the stratum downwards; after drilling of the horizontal cantilever pile hole is completed and the horizontal drilling device is retracted, the sliding horizontal drilling assembly moves downwards under the dead weight of the sliding horizontal drilling assembly and makes contact with 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水平悬臂的矩形抗滑桩机械成孔方法，包括：在钻机上自上而下依次设置渣体处理机构、滑动水平钻组件及竖向钻装置，滑动水平钻组件位于竖向钻装置顶部并沿竖向方向进行上下移动；控制竖向钻装置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，形成矩形桩孔的自由段；在滑动水平钻组件到达水平悬臂桩孔的底部设计标高后，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；同时继续控制竖向钻装置上的圆柱钻组件向下钻挖地层；水平悬臂桩孔钻挖完成回缩水平钻装置后滑动水平钻组件在其自重下向下移动并接触于竖向钻装置，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。
