Anchor cable hole collapse prevention structure and drilling method
The invention relates to an anchor cable hole collapse prevention structure and a drilling method.The anchor cable hole collapse prevention structure comprises a drill hole, a steel pipe sleeve, a steel wire mesh sleeve and an anchor cable, and the drill hole is formed in a side slope; the steel pipe casing pipe extends in the length direction of the drill hole, the steel pipe casing pipe is arranged in the drill hole in a sleeved mode, and the outer wall of the steel pipe casing pipe abuts against the inner wall of the drill hole; the steel wire mesh sleeve is tightly arranged in the steel pipe sleeve and extends into the drill hole by a preset length, the steel wire mesh sleeve is provided with an open end and a closed end in the length direction, the closed end is located in the drill hole, and the open end is located in the steel pipe sleeve; the anchor cable is arranged in the steel pipe sleeve and the steel wire mesh sleeve and extends out of the slope; the steel pipe sleeve comprises a plurality of sections of steel floral pipes, every two adjacent sections of steel floral pipes are connected through threads, and a plurality of grout diffusion holes are formed in the steel floral pipes at intervals in the length direction. The hole collapse prevention structure for the anchor cable hole can quickly and effectively complete hole drilling and ensure the effectiveness of the anchoring end of the anchor cable, so that the stability of a side slope is ensured.
本申请涉及一种锚索孔防塌孔结构及钻进方法，防塌孔结构包括钻孔、钢管套管、钢丝网套和锚索，其中，钻孔设置于边坡内；钢管套管沿钻孔的长度方向延伸，钢管套管套设于钻孔内，且钢管套管的外壁与钻孔的内壁抵接；钢丝网套紧密设置于钢管套管内并向钻孔内延伸预设长度，钢丝网套在长度方向上具有开口端和封闭端，封闭端位于钻孔内、开口端位于钢管套管内；锚索设置于钢管套管和钢丝网套内并向边坡外延伸；钢管套管包括多节钢制花管，相邻两节钢制花管之间通过螺纹进行连接，钢制花管沿长度方向间隔设置有多个浆液扩散孔。该锚索孔防塌孔结构能够快速有效的完成钻孔并保证锚索锚固端的有效性，从而保障边坡稳定。
