Mechanical hole forming method for reaming step-by-step drilling rectangular anti-slide pile with horizontal cantilever
The invention discloses a mechanical hole forming method for a hole-reaming step-by-step drilling rectangular anti-slide pile with a horizontal cantilever, which comprises the following steps of: combining a plurality of drilling machines to form a rectangular structure corresponding to a rectangular pile hole in size; a slag treatment mechanism, a horizontal drilling assembly and a vertical drilling device are sequentially arranged on each drilling machine from top to bottom; vertical drilling devices on all the drilling machines are controlled to vertically drill the stratum downwards till the designed depth of the horizontal cantilever is reached; a horizontal hydraulic cylinder on a drilling machine arranged close to the horizontal cantilever pile hole excavation part is controlled to drive a horizontal drilling device to horizontally move outwards to drill and excavate the stratum to the designed length, so that a horizontal cantilever pile hole is formed; and the vertical drilling devices on all the drilling machines continue 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 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分步式钻挖带水平悬臂的矩形抗滑桩机械成孔方法，包括：将多个钻机进行组合，以形成同矩形桩孔尺寸相对应的矩形结构；在各钻机上自上而下依次设置渣体处理机构、水平钻组件以及竖向钻装置；控制所有钻机上的竖向钻装置竖直向下钻挖地层直至水平悬臂的设计深度；控制靠近水平悬臂桩孔开挖部设置的钻机上的水平液压缸驱动水平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；继续控制所有钻机上的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：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。
