End anchoring-secondary reinforcing bag type grouting anchor rod and anchoring method
The invention relates to an end anchoring-secondary reinforcing bag type grouting anchor rod and an anchoring method. The end anchoring-secondary reinforcing bag type grouting anchor rod comprises an end spiral anchor rod body, a special-shaped anchor rod body, an anchoring disc, an anchoring nut, a connecting screw thread, a plug, a grouting connector, an annular supporting protrusion, an inner lining pipe, a grouting rubber sleeve and an inner lining pipe fixing rod, and a rubber sleeve grouting pipe is axially fixed to the outer wall of the inner lining pipe. The ends of the rubber sleeve grouting pipes penetrate through the side walls of the grouting rubber sleeves and extend into all the grouting rubber sleeves, openings are formed in the portions, located in the grouting rubber sleeves, of the rubber sleeve grouting pipes, and one-way valves are arranged in the openings. The equipment structure can be flexibly adjusted according to use requirements, and meanwhile the construction process is simple and easy to master; the strength and the positioning stability of the positioning connection structure between the anchor rod and the anchoring hole are greatly improved; the broken surrounding rock can be grouted and reinforced again in the service process of the anchor rod, and then the anchoring force of the anchor rod is improved again.
本发明涉及一种端锚‑二次补强囊袋式注浆锚杆及锚固方法，包括端部螺旋锚杆、异形锚杆、锚固盘、锚固螺母、连接丝扣、堵头、注浆接头、环状支撑凸起、内衬套管、注浆胶套、内衬管固定杆，内衬套管外壁轴向固定有胶套注浆管，胶套注浆管端部贯穿注浆胶套侧壁延伸至所有注浆胶套内，位于注浆胶套内的胶套注浆管上设有开口，开口内设有单向阀。本发明可根据使用需要灵活调整设备结构，同时施工工艺简单易掌握；极大的提高锚杆与锚固孔间定位连接结构的强度及定位稳定性；可以在锚杆服务过程中对破碎围岩再次注浆加固，进而再次提升锚杆的锚固力。
