Multi-stage pressure dispersion type anti-pulling anchor rod suitable for rock slope
The multistage pressure dispersion type anti-pulling anchor rod comprises an anchor rod body, and a plurality of self-anchoring mechanisms are arranged on the anchor rod body in the length direction of the anchor rod body; the self-anchored mechanism comprises a plurality of salix leaf support assemblies which are circumferentially arranged on the outer wall of the anchor rod and located on the same plane, one ends of the salix leaf support assemblies are movably connected with the outer wall of the anchor rod, and the salix leaf support assemblies are in an umbrella-shaped moving state. Load is transmitted to the grouting body of the anchoring section of the anchor rod in a pressure dispersing mode through the salix leaf support assembly, so that the grouting body of the anchoring section of the anchor rod is pressed to expand and is in a three-direction pressure stress state, the pulling resistance of the anchor rod is improved, and therefore the anchoring force of the anchor rod is improved.
本发明公开一种适用于岩质边坡多级压力分散型抗拔锚杆，包括锚杆，锚杆上沿其长度方向设有若干自锚机构；自锚式机构包括若干柳叶支架组件，若干柳叶支架组件周向设置在锚杆外壁上，并位于同一平面，且若干柳叶支架组件的一端与锚杆外壁活动连接，若干柳叶支架组件的活动状态为伞状形式，本发明通过利用柳叶支架组件将荷载以分散压力形式传递给锚杆锚固段的注浆体，使得锚杆锚固段注浆体受压发生膨胀而处于三向压应力状态，提高锚杆的抗拔力度，从而提高锚杆的锚固力。
