Step-by-step drilling and digging rectangular anti-slide pile mechanical hole forming method with haunched horizontal cantilever
The invention discloses a step-by-step drilling and excavating rectangular anti-slide pile mechanical hole forming method with a haunched horizontal cantilever. The method comprises the steps that a slag treatment mechanism, a multifunctional drilling assembly and a vertical drilling device are sequentially arranged on a drilling machine from top to bottom; the vertical drilling device is controlled to vertically drill the stratum downwards till the designed depth of the horizontal cantilever, so that a free section of the rectangular pile hole is formed; the multifunctional drilling device is started, the multifunctional drilling device gradually rotates outwards with the connecting shaft as the rotating center and drills and digs the stratum at the same time, and haunching holes are formed; a horizontal hydraulic cylinder is controlled to drive the multifunctional drilling device to horizontally move outwards to drill and dig the stratum to the designed length, so that a horizontal cantilever pile hole is formed; and the vertical drilling device 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. The method has the advantages that the horizontal cantilever structure with the haunch and the vertical pile body can form holes at a time, other mechanical assistance is not needed, and the purposes of improving the construction efficiency and saving the construction and equipment cost are achieved.
本发明公开了一种分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：在钻机上自上而下依次设置渣体处理机构、多功能钻组件以及竖向钻装置；控制竖向钻装置竖直向下钻挖地层直至水平悬臂的设计深度，以形成矩形桩孔的自由段；开启多功能钻装置，多功能钻装置以连轴为旋转中心逐渐向外旋转并同时进行钻挖地层，以形成加腋孔；控制水平液压缸驱动多功能钻装置向外水平移动钻挖地层至设计长度，以形成水平悬臂桩孔；继续控制竖向钻装置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。本发明的优点是：带加腋的水平悬臂结构和竖向桩身均可一次成孔，无需其他机械辅助，达到提高施工效率、节省施工和设备成本目的。
