Step-by-step drilling construction method for air bag retaining wall type rectangular anti-slide pile with horizontal cantilever
The invention discloses a step-by-step drilling construction method for an air bag retaining wall type rectangular anti-slide pile with a horizontal cantilever. The step-by-step drilling construction method comprises the steps that a rock slag treatment mechanism and a multifunctional drilling assembly are sequentially arranged on a drilling machine from top to bottom; a cylindrical drill assembly on the horizontal plane in the multifunctional drill assembly is controlled to drill and dig the rock-soil body downwards till the designed depth of the horizontal cantilever pile hole, and a free section of the rectangular pile hole is formed; the multifunctional drill assembly is moved upwards to the designed elevation of the top of the haunched hole, and cylindrical drill assemblies, on the vertical face and the horizontal face, in the multifunctional drill assembly drill and dig the haunched hole towards the side portion of the rectangular pile hole; a horizontal hydraulic cylinder is controlled to drive a cylindrical drill assembly on the vertical face in the multifunctional drill assembly to drill the horizontal cantilever pile hole outwards till the designed length of the horizontal cantilever pile hole is reached; and a piston rod of the horizontal hydraulic cylinder retracts to the minimum stroke and stops working, and a cylindrical drill assembly on the horizontal plane in the multifunctional drill assembly continues to be controlled to vertically drill the rock-soil body downwards to the designed depth of the rectangular pile hole so as to form a built-in section of the rectangular pile hole.
本发明公开了一种气囊护壁式带水平悬臂的矩形抗滑桩分步钻孔施工方法，包括：在钻机上自上而下依次设置岩渣处理机构和多功能钻组件；控制多功能钻组件中在水平面上的圆柱钻组件向下钻挖岩土体直至水平悬臂桩孔设计深度，形成矩形桩孔的自由段；将多功能钻组件向上移动至加腋孔的顶部设计标高，多功能钻组件中在竖向面和水平面上的圆柱钻组件向矩形桩孔的侧部钻挖加腋孔；控制水平液压缸驱动多功能钻组件中在竖向面上的圆柱钻组件向外钻挖水平悬臂桩孔，直至水平悬臂桩孔的设计长度；使水平液压缸的活塞杆回缩至最小行程并停止工作，继续控制多功能钻组件中在水平面上的圆柱钻组件竖直向下钻挖岩土体至矩形桩孔的设计深度以形成矩形桩孔的嵌固段。
