Yielding anchor cable
The invention discloses a yielding anchor cable. The yielding anchor cable comprises a cable body and a yielding mechanism; the yielding mechanism comprises an inner cylinder body, an outer cylinder body, a cylinder cover, a piston ring and piston rods, wherein the inner cylinder body is a hollow cylinder, the cylinder cover is provided with a center hole and rod holes matched with the piston rods, and the cable body penetrates through a hollow part of the inner cylinder body a center hole of the cylinder cover and is linked with the piston rods; a working chamber, of which the section is of an annular shape, is formed by the inner cylinder body, the outer cylinder body and the cylinder cover, the piston ring is arranged in the working chamber, the top of the piston ring is connected with the at least two piston rods, a compression medium is arranged between the bottom part of the piston ring and the bottom part of the working chamber, and the piston rod penetrates through the rod holes and is driven to move by the cable body; a pressure releasing pathway is arranged at the bottom of the inner cylinder body, and is internally provided with a safety valve which is automatically started and closed according to a preset pressure valve. The yielding anchor cable provided by the invention is higher in permitted deformation, high in bearing capacity and constant in resistance, and the large deformation demand of surrounding rocks can be met.
