Improved expanded head bag type anchor rod and construction method thereof
The improved expanded head bag type anchor rod comprises a rod body, the bottom end of the rod body is fixedly connected with a guide cone, and a trigger assembly is installed on the guide cone; the self-centering mechanism comprises an elastic centering frame fixedly arranged at the bottom of the rod body in a sleeving mode, the top end of the elastic centering frame is fixedly connected with a grouting pipe and an exhaust pipe, the bottom end of the grouting pipe and the bottom end of the exhaust pipe both extend into the elastic centering frame, the bottom end of the grouting pipe is located below the bottom end of the exhaust pipe, and an elastic clamping assembly is installed at the bottom end of the elastic centering frame. The triggering assembly is used for triggering the elastic clamping assembly, a limiting assembly is fixedly connected in the elastic centering frame, a clamping column is fixedly connected to the inner wall of the bottom end of the elastic centering frame, and the limiting assembly is detachably connected with the clamping column; the special-shaped bag body is located in the elastic centering frame, and the special-shaped bag body is fixedly connected with the elastic centering frame; the upper fixing assembly is detachably connected to the top of the rod body. After the self-centering anchor rod is placed at the bottom of a hole, self-centering of the anchor rod can be achieved, and the better anchoring effect is achieved.
本发明公开了改良型扩大头囊式锚杆，包括：杆体，杆体底端固接有导向锥，导向锥上安装有触发组件；自定心机构，自定心机构包括固定套设在杆体底部的弹性定心框架，弹性定心框架顶端固接有注浆管和排气管，注浆管和排气管的底端均伸入弹性定心框架内，且注浆管底端位于排气管底端下方，弹性定心框架底端安装有弹性卡接组件，触发组件用于触发弹性卡接组件，弹性定心框架内固接有限位组件，弹性定心框架底端内壁固接有卡柱，限位组件与卡柱可拆卸连接；异型囊体，异型囊体位于弹性定心框架内，且异型囊体与弹性定心框架固接；上固定组件，上固定组件可拆卸连接在杆体顶部。本发明在放入洞底后能够实现锚杆的自定心，用以实现更好地锚固效果。
