Hole bottom energy-releasing pressure-yielding grouting anchor rod and construction method thereof
The invention discloses a hole bottom energy-releasing pressure-yielding grouting anchor rod and a construction method thereof. The anchor rod comprises a rod body and a support pad plate, wherein thefront portion of the rod body is connected with a pressure-yielding anchor pipe device in a sleeved manner; the pressure-yielding anchor pipe device comprises a pressure-yielding sleeve with internalthreads, a braking nut arranged at the rear end of the pressure-yielding sleeve and an inner sliding part arranged inside the pressure-yielding sleeve, and the inner sliding part is in extrusion fitwith the internal threads of the pressure-yielding sleeve; and the front portion of the rod body is fixedly connected with the inner sliding part inside the pressure-yielding sleeve after penetratingthrough the braking nut, and the rear portion of the rod body is in coordination with the support pad plate through a locking nut. By means of the hole bottom energy-releasing pressure-yielding grouting anchor rod, anchoring can be performed rapidly to form supporting protection force, meanwhile, prestress can be formed to control initial deformation, and the hole bottom energy-releasing pressure-yielding grouting anchor rod has a pressure-yielding slip function, energy released from the formation is absorbed to improve the anchor rod safety, and the anchor rod durability is improved by a special grouting full-bonding functional design.
本发明公开了一种孔底释能让压的注浆锚杆及其施工方法，其中锚杆包括杆体和支承垫板，所述杆体的前部套接有让压锚管装置；所述让压锚管装置包括带内螺纹的让压套筒、设置在让压套筒后端的制动螺母以及设置在让压套筒内的内滑件，所述内滑件与让压套筒的内螺纹挤压配合；所述杆体的前部穿过制动螺母后与让压套筒内的内滑件固定连接，杆体的后部通过锁定螺母与支承垫板配合。利用本发明的锚杆，可以迅速锚固形成支护力，同时可以形成预应力控制初期变形、并具让压滑移的功能、吸收地层释放的能量、提高锚杆安全性，专门的注浆全粘结功能设计提高了锚杆的耐久性。
