Asynchronous type drilling and excavating rectangular anti-slide pile mechanical hole forming method with haunched horizontal cantilever
The invention discloses an asynchronous drilling and excavating rectangular anti-slide pile mechanical hole forming method with a haunched horizontal cantilever. The method comprises the following steps that a sludge treatment mechanism, a haunched drilling assembly, a horizontal drilling assembly and a vertical drilling device are sequentially arranged on a drilling machine; a haunching drill assembly and a horizontal drill assembly are in a standby state, a vertical drill device is controlled to vertically drill and dig a rock-soil body downwards to the designed depth of a horizontal cantilever, and a rectangular pile hole free section is formed; a vertical drilling device stops drilling and digging, a haunching drilling device in a haunching drilling assembly is controlled to rotate outwards from a vertical state to a horizontal state so as to drill and dig the rock-soil body, and a haunching hole is formed; a horizontal hydraulic cylinder in the horizontal drilling assembly is controlled to drive a horizontal drilling device to horizontally move outwards to drill and dig the rock-soil body, and a horizontal cantilever pile hole is formed; and the haunching drilling device and the horizontal drilling device are reset, 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 advantage that a rectangular pile hole with a horizontal cantilever and a haunching structure can be drilled in a rock-soil body at a time.
本发明公开了一种异步式钻挖带加腋水平悬臂的矩形抗滑桩机械成孔方法，包括以下步骤：在钻机上依次设置泥渣处理机构、加腋钻组件、水平钻组件及竖向钻装置；使加腋钻组件和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，形成矩形桩孔自由段；使竖向钻装置停止钻挖，控制加腋钻组件中的加腋钻装置从竖直状态向外旋转至水平状态以钻挖岩土体，形成加腋孔；控制水平钻组件中的水平液压缸驱动水平钻装置向外水平移动钻挖岩土体，形成水平悬臂桩孔；将加腋钻装置和水平钻装置进行复位，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：可在岩土体内一次性钻挖带水平悬臂和加腋结构的矩形桩孔。
