Anchoring device of telescopic recoverable anchor rod and using method of anchoring device
The invention discloses an anchoring device of a telescopic recoverable anchor rod and a using method of the anchoring device, and belongs to the field of underground engineering supporting and the technical field of geotechnical engineering. The device comprises an anchor rod, an anchor rod end recycling device, a metal resistance increasing sleeve and an annular tray, wherein the anchor rod end recycling device is composed of a metal support, a sliding metal pipe and an L-shaped high-strength metal clamp, and the anchor rod can be separated from an anchoring device by applying external force to enable the anchor rod to move deeply in the metal resistance increasing sleeve. When a coal mining working face of a coal mine is stoped, the anchor rod needs to be pulled out, and gas explosion caused by sparks generated by cutting of a coal cutter and the anchor rod is prevented; the anchor rod can be pulled out of the anchor hole, the anchor rod can be recycled, economic cost is saved, meanwhile, the situation that the anchor rod is left in a rock-soil body, pollution and the like are caused, and the follow-up underground space development is affected is avoided, and under the condition that the supporting requirement is not affected, the anchor rod has the advantages of being safe to use, convenient and fast to install, environmentally friendly, good in economic benefit and the like.
本发明公开的一种伸缩式可回收锚杆的锚固装置及其使用方法，属地下工程支护领域和岩土工程技术领域。装置包括锚杆、由金属支座，滑移金属管和L型高强度金属夹具组成的锚杆端头回收装置、金属增阻套筒和环形托盘，通过施加外力使锚杆在金属增阻套筒内向深处移动即可让锚杆脱离锚固装置。煤矿采煤工作面回采时，需要将锚杆抽出，防止割煤机与锚杆切割打出火花，引发瓦斯燃爆；将锚杆从锚孔中拔出，还能使得锚杆能够重复利用，节省了经济成本，同时避免了锚杆残留在岩土体中从而造成污染等影响后续地下空间的发展，在不影响支护要求的条件下，拥有使用安全、安装便捷、绿色环保、经济效益好等优点。
