Anchoring force enhanced anchor cable structure for sleeve pull rod type nailing surrounding rock grouting
The invention discloses an anchoring force enhanced anchor cable structure for sleeve pull rod type nailing surrounding rock grouting. The anchor cable structure comprises an anchorage device, a gasket, a pressure dividing plate, a grout stopping plug, a grouting pipe, an anchor cable bundle, a connecting rod, a drawing rod, an anchor cable bundle support, a steel pipe, a conical rock penetrating grouting nail, a guide head, a rivet, a connecting support, a nut and a bearing plate. The conical rock-penetrating grouting nail is installed on the core part drawing rod through the connecting rod and the rivet, a linkage device is formed, and the radial size expansion of the anchor cable structure is guaranteed. And the anchor cable bundle, the grouting pipe and the drawing rod are arranged in parallel and are supported by the anchor cable bundle bracket, so that the stability of the anchor cable structure is enhanced. The conical rock-penetrating grouting nails are extruded out of the wall of the steel pipe and inserted into the hole wall of the soft rock by pulling out the pull rod, the grouting range of the anchor cable structure is enlarged, the anchoring force, the cohesive force and the mechanical occlusal force of the solidified grouting body on the surrounding soft rock are increased, and then the reinforcing effect on the side slope is enhanced.
本发明公开一种套管拉杆式入钉围岩注浆的锚固力增强型锚索结构，该锚索结构包括锚具、垫片、分压板、止浆塞、注浆管、锚索束、连接杆、抽拉杆、锚索束支架、钢管、锥形穿岩注浆钉、导向头、铆钉、连接支架、螺母、承载板。锥形穿岩注浆钉通过连接杆、铆钉安装在核心部件抽拉杆上，形成一套联动装置，保证了锚索结构的径向尺寸拓展。将锚索束、注浆管与抽拉杆平行设置，并通过锚索束支架对其进行支撑，增强了锚索结构的稳定性。通过拉出抽拉杆使锥形穿岩注浆钉挤出钢管壁并插入到软岩孔壁，增加了该锚索结构的注浆范围，增加了注浆体固化后对周围软岩的锚固力、黏聚力、机械咬合力，进而加强了对边坡的加固作用。
