Energy-releasing yielding anchor rod
The invention discloses an energy-releasing yielding anchor rod, and belongs to the technical field of geotechnical engineering surrounding rock supporting. The energy-releasing yielding anchor rod comprises a rod body, a yielding sleeve and a base plate; the periphery of the rod body is sleeved with the yielding sleeve; one end of the yielding sleeve is connected with the base plate; a yielding ring is arranged on the inner side of the other end of the yielding sleeve; an abutting ring is fixedly connected to the rod body; the outer diameter of the abutting ring is smaller than the inner diameter of the yielding sleeve; a yielding pipe is arranged between the rod body and the yielding sleeve and located between the yielding ring and the abutting ring; the outer diameter of the yielding pipe is smaller than the inner diameter of the yielding sleeve and larger than the inner diameter of the yielding ring; and the outer diameter of the abutting ring is larger than the inner diameter of the yielding pipe. The energy-releasing yielding anchor rod has the advantages of being stable in yielding and convenient to assemble and install, the manufacturing cost and the construction cost can be reduced, and the workload of constructors is reduced.
本发明公开了一种释能让压锚杆，属于岩土工程围岩支护技术领域。其包括杆体、让压套筒和垫板，所述让压套筒套设于杆体外周，所述让压套筒的一端与垫板连接，另一端内侧设置有让压环。所述杆体上固定连接有抵接环，所述抵接环的外径小于让压套筒的内径。所述杆体与让压套筒之间设置有让压管，所述让压管位于让压环与抵接环之间，所述让压管的外径小于让压套筒的内径，且大于让压环的内径，所述抵接环的外径大于让压管的内径。本发明具有让压稳定、便于装配和安装的优点，有利于降低造价成本和施工成本，减少施工人员的工作量。
