Mechanical hole forming method for step-by-step drilling and digging of rectangular anti-slide pile with horizontal cantilever
The step-by-step drilling rectangular anti-slide pile mechanical hole forming method comprises the following steps that a sludge treatment mechanism, a horizontal drilling assembly and a vertical drilling device are sequentially arranged on a drilling machine, and the horizontal drilling assembly comprises the horizontal drilling device driven by a horizontal hydraulic cylinder; the vertical drilling device comprises a plurality of cylindrical drilling assemblies forming a rectangular excavation face. A horizontal drilling assembly is in a standby state, and a vertical drilling device is controlled to vertically drill and dig the rock-soil body downwards to the designed depth of a horizontal cantilever, so that a free section of the rectangular pile hole is formed; the vertical drilling device stops drilling, the horizontal drilling device is controlled to horizontally move outwards to drill and dig the rock-soil body to the designed length, and a horizontal cantilever pile hole is formed; and the horizontal drilling device retracts and stops working, and the vertical drilling device is controlled to drill and dig the rock-soil body downwards to the designed depth of the rectangular pile hole. The method has the advantages that the horizontal rectangular pile hole can be drilled in the rock-soil body, the horizontal cantilever structure and the vertical pile body rectangular pile hole can be formed at a time, other mechanical assistance is not needed, and the purposes of improving the construction efficiency and saving the construction cost are achieved.
本发明公开了一种分步式钻挖带水平悬臂的矩形抗滑桩机械成孔方法，包括以下步骤：在钻机上依次设置泥渣处理机构、水平钻组件以及竖向钻装置，水平钻组件包括由水平液压缸驱动的水平钻装置；竖向钻装置包括若干组成矩形开挖面的圆柱钻组件；使水平钻组件处于待机状态，控制竖向钻装置竖直向下钻挖岩土体至水平悬臂的设计深度，以形成矩形桩孔的自由段；使竖向钻装置停止钻挖，控制水平钻装置向外水平移动钻挖岩土体至设计长度，以形成水平悬臂桩孔；水平钻装置回缩并停止工作，控制竖向钻装置向下钻挖岩土体至矩形桩孔的设计深度。本发明的优点是：能在岩土体内钻挖水平矩形桩孔，并且水平悬臂结构和竖向桩身矩形桩孔均可一次成孔，无需其他机械辅助，达到提高施工效率、节省施工成本的目的。
