Expansion type recoverable anchor rod and using method thereof
The invention relates to an expansion type recoverable anchor rod and a using method thereof, and belongs to the technical field of anchor rods. The expansion type recoverable anchor rod comprises a hollow expansion rod and a rotary extrusion rod, a plurality of expansion plates are installed at the front end of the expansion rod, a supporting rod is rotationally connected to the inner wall of each expansion plate, the end, away from the corresponding expansion plate, of each supporting rod is rotationally connected to a pressure bearing button, a first spring is installed in the middle of each supporting rod, and a second spring is installed in the middle of each supporting rod. The end, away from the corresponding supporting rod, of each first spring is connected to the metal ball. A plurality of holes are formed in the expansion rod, a plurality of telescopic rods are installed on the inner wall of the expansion rod, the other end of each expansion rod is connected to the inner wall of the expansion rod through a plurality of second springs, a conical block matched with the corresponding hole is arranged on the inner side of each telescopic rod, and a wedge-shaped circular truncated cone is arranged on the rotary extrusion rod. During construction, grouting is not needed, recycling is convenient, the construction efficiency is greatly improved, and the cost is saved.
本发明涉及一种膨胀式可回收锚杆及其使用方法，属于锚杆技术领域。所述膨胀式可回收锚杆包括中空的膨胀杆和旋转挤压杆，所述膨胀杆前端安装有多个膨胀板，各所述膨胀板内壁上均转动连接有支撑杆，各所述支撑杆远离对应膨胀板的一端均转动连接在承压钮上，各所述支撑杆中部均安装有第一弹簧，各所述第一弹簧远离对应支撑杆的一端均连接在金属球上；所述膨胀杆上开设有多个孔洞，所述膨胀杆内壁上安装有多个伸缩杆，各所述膨胀杆另一端通过多个第二弹簧连接在所述膨胀杆的内壁上，每个伸缩杆内侧均设有与所述孔洞相匹配的锥块，所述旋转挤压杆上设有楔形圆台。本发明在施工时无需注浆，便于回收，极大的提高了施工效率，节约了成本。
