Double-track drilling method for anti-slide pile or retaining wall with horizontal boss and variable sawtooth angle
The invention discloses a double-track drilling method for an anti-slide pile or retaining wall with a horizontal boss and variable sawtooth angles, which comprises the following steps of: sequentially arranging a hoisting assembly and a U-shaped steel frame on a drilling machine from top to bottom, a horizontally arranged orthogonal track drill assembly, a vertically arranged transverse cutting track drill and a vertically arranged conical drill assembly are mounted on the U-shaped steel frame; the orthogonal track drill and the transverse cutting track drill are controlled to drill and dig the rock-soil body downwards to the designed depth of vertical drilling; the horizontal angle between the conical drill and the conical drill U-shaped steel frame is adjusted through the rotating assembly, a telescopic rod of the horizontal hydraulic cylinder extends to drive the conical drill to move laterally, and the power assembly drives the cutter head assembly to rotate to drill and dig a rock-soil body so as to form a conical hole. And the translation assembly drives the orthogonal crawler drill to laterally drill and dig the rock-soil body, so that a horizontal drill hole is formed. The method has the advantages that the component force block hole with the optimal vertical component force angle with the residual gliding force is drilled according to the residual gliding force directions of different side slopes.
本发明公开了一种带水平凸台与可变锯齿角度抗滑桩或挡墙双履带钻孔方法，方法包括以下步骤：在钻机上自上而下依次设置起吊组件和U形钢架，并在U形钢架上安装水平设置的正交履带钻组件、竖向设置的横切履带钻和竖向设置的圆锥钻组件；控制正交履带钻和横切履带钻向下钻挖岩土体至竖向钻孔的设计深度；通过转动组件调节圆锥钻与圆锥钻U形钢架之间的水平角度，水平液压缸的伸缩杆伸长以驱动圆锥钻进行侧向移动，动力组件驱动刀盘组件转动来钻挖岩土体，以形成圆锥孔；使平移组件驱动正交履带钻侧向钻挖岩土体，以形成水平钻孔。本发明的优点是：实现根据不同边坡的剩余下滑力方向，钻挖与剩余下滑力的竖向分力角度成最优的分力块孔。
