Hollow anchor rod for releasing energy and yielding pressure at orifice and construction method of hollow anchor rod
The invention discloses a hollow anchor rod for releasing energy and yielding pressure at an orifice and a construction method of the hollow anchor rod. The hollow anchor rod includes a hollow rod body, an anchor head, a yielding sleeve and a supporting pad, the outer part of the rear part of the yielding sleeve is matched with the supporting pad, and is internally provided with internal sliding parts; the internal sliding parts are matched with the internal threads of the yielding sleeve in an extruded mode; the hollow rod body successively penetrates through the internal sliding parts and connected with the anchor head; and the hollow rod body is fixed with the internal sliding parts. According to the hollow anchor rod for releasing energy and yielding pressure at the orifice, the hollowanchor rod has performance of rapidly-forming supporting force of tensioning prestress, pressure yielding and sliding performance can absorb energy released by the stratum, and the safety of the anchor rod is improved; pressure yielding and sliding values can be conveniently obtained through scales set on the anchor rod; and the grouting function can make the whole length of the anchor rod bond,and long-term durability is brought.
本发明公开了一种孔口释能让压的中空锚杆及其施工方法，其中锚杆包括中空杆体、锚头、让压套筒和支承垫板，所述让压套筒后部的外部与支承垫板配合，内部设有内滑件；所述的内滑件与让压套筒的内螺纹挤压配合；所述的中空杆体依次穿过内滑件后与锚头连接；所述的中空杆体与内滑件固定。本发明的中空锚杆，具有可张拉预应力的快速形成支护力的性能，其让压滑移性能能吸收地层释放的能量，提高锚杆安全性；锚杆上设置刻度尺可以方便获取锚杆的让压滑移值；可注浆的功能，使锚杆全长粘结，具有长期耐久性。
