Novel expansion shell type hollow post-grouting expanded head anchor rod and construction technology thereof
The invention discloses a novel expansion shell type hollow post-grouting expanded-head anchor rod and a construction technology thereof, and belongs to the technical field of anchor rods, the novel expansion shell type hollow post-grouting expanded-head anchor rod comprises a rod body, a connecting block installed on the bottom face of the rod body, a drill bit fixed to the bottom face of the connecting block and a rotating sleeve arranged on the periphery of the rod body in a sleeving mode, and the rotating sleeve can drive the connecting block to rotate; a mounting groove is formed in the periphery of the rotating sleeve, two mounting rings are arranged on the periphery of the rotating sleeve in a sleeving mode, the mounting rings are rotationally connected with the rotating sleeve, a plurality of abutting plates arranged in the circumferential direction of the rotating sleeve at intervals are arranged on the periphery of the rotating sleeve, and two first springs are fixed to the side faces, close to the rotating sleeve, of the abutting plates; the end, away from the abutting plate, of the first spring is fixedly connected with the peripheral face of the mounting ring. The rotating sleeve is provided with a pushing piece used for pushing the abutting plate to move in the direction away from the rotating sleeve. The method has the effect of reducing the hole collapse possibility.
本申请公开了一种新型涨壳式中空后注浆扩大头锚杆及其施工工艺，属于锚杆的技术领域，其包括杆体、安装于杆体底面的连接块、固定于连接块底面的钻头及套设于杆体外周的转动套筒，转动套筒可带动连接块转动，转动套筒的外周开设有安装槽，转动套筒的外周套设有两个安装环，安装环与转动套筒转动连接，转动套筒的外周设置有若干个沿自身周向间隔设置的抵接板，抵接板靠近转动套筒的侧面固定有两个弹簧一，弹簧一远离抵接板的一端与安装环的外周面固定连接；转动套筒上设置有用于推动抵接板朝向远离转动套筒的方向移动的推动件。本申请具有减小塌孔可能性的效果。
