Pressure relief anchor pipe
The invention provides a pressure relief anchor pipe and relates to the technical field of anchor pipes, the pressure relief anchor pipe comprises a pipe body, an end elastic piece and a resistance increasing piece, one end of the pipe body is used for extending into a hole, the other end of the pipe body is located outside the hole, the hole is formed in surrounding rock, the end elastic piece is arranged on the pipe body outside the hole, and one end of the end elastic piece is used for transmitting elastic force to the surrounding rock; the resistance increasing piece is arranged between the portion, in the hole, of the pipe body and the inner wall of the hole, the resistance increasing piece makes contact with the outer wall of the pipe body and the inner wall of the hole, and when the resistance increasing piece bears stress applied by surrounding rock deformation, the resistance increasing piece can move relative to the pipe body and generate friction with the pipe body. According to the scheme, the pressure relief and energy absorption capacity can be improved, the stability of surrounding rock is enhanced, and the structure is simple.
本发明提供一种卸压锚管，涉及锚管技术领域，包括管体、端部弹性件和增阻件，管体的一端用于伸入孔中，另一端位于孔外，孔在围岩中形成，端部弹性件设置于孔外的管体上，且端部弹性件的一端用于将弹力传递至围岩，另一端能够将弹力传递至管体上，增阻件设置于孔内的管体与孔的内壁之间，增阻件与管体外壁以及孔的内壁相接触，增阻件在受到围岩变形所施加的应力时能够与管体发生相对运动并产生摩擦。本发明提供的方案能够提高卸压吸能能力、增强围岩的稳定性且结构简单。
