Precession type grouting anchor rod structure and using method
The invention discloses a screw-in type grouting anchor rod structure and a using method. The screw-in type grouting anchor rod structure comprises an anchor rod body, a grouting pipe, a tray and a nut. The whole anchor rod body is provided with threads, one end of the anchor rod body is provided with a drill bit with a curvature continuous change round hole in the bottom, the grouting pipe and the round hole in the bottom of the drill bit form a two-stage grouting structure through nesting, a supporting structure is formed after high-pressure grouting, and the other end of the anchor rod bodyis connected with the tray and the nut through the threads. The anchor rod body is drilled, external support is formed through grouting impact after drilling is completed, a two-stage grouting structure is formed and makes direct contact with a rock-soil body, the problem that anchoring force is reduced due to the fact that a traditional anchor rod is corroded in rock-soil for a long time can besolved, and the anchor rod is simple in manufacturing mode and operation mode, easy to construct and high in anchoring force.
一种旋进式注浆锚杆结构及使用方法，包括锚杆主体、注浆管、托盘及螺母；锚杆主体整体设有螺纹，一端设有底部带有曲率连续性变化圆孔的钻头，注浆管与钻头底部的圆孔通过嵌套形成两级注浆结构，待高压注浆后形成支撑结构，锚杆主体的另一端通过螺纹与托盘和螺母连接。本发明通过锚杆主体钻孔，并在钻孔完成后经注浆冲击形成外部支撑，组成两级注浆结构，直接与岩土体进行接触，能够解决传统锚杆长期在岩土中腐蚀所带来的锚固力下降的问题，制作方式和操作方式简单、易施工、锚固力高。
