Hole collapse prevention steel flower anchor pipe and using method thereof
The invention provides a hole collapse prevention steel flower anchor pipe and a using method thereof. The hole collapse prevention steel flower anchor pipe comprises a pipe body with the interior of a hollow structure, one end of the pipe body is provided with a connecting component used for being connected with an anchor rod motor, the other end of the pipe body is provided with a screwing-in component composed of a protrusion and a notch, therefore the steel flower anchor pipe can be conveniently screwed into a drill hole, a plurality of regularly-arranged grouting holes are formed in the outer side of the pipe body, the grouting holes are formed so that slurry can permeate into a rock-soil layer through the grouting holes during later grouting, anchoring is facilitated, a kerf is further formed in the pipe wall of the pipe body, and when the steel flower anchor pipe is screwed into the drill hole, the kerf can scrape residues on the wall of the drill hole into the pipe body, and cleaning of the interior of the drill hole in the later period is facilitated.
本发明提供了一种防塌孔钢花锚管及其使用方法，该钢花锚管包括内部为空心结构的管体，管体的一端设有用于与锚杆电机连接的连接部件，管体的另一端设有由凸起和缺口组合成的旋入部件，使钢花锚管便于旋入钻孔中，管体的外侧设有若干个规则排列的注浆孔，设置注浆孔便于后期注浆时浆体通过注浆孔渗入岩土层中，利于锚固，在管体的管壁上还设有切缝，设置切缝能够在钢花锚管旋入钻孔时，切缝对钻孔壁上的残渣刮入到管体内部，方便后期对钻孔内部的清理。
