Anchor cable with framework expanding body
The invention discloses an anchor cable anchor cable with a framework expanding body. The anchor cable comprises a grouting pipe, a head guard, an upper clamp, a lower clamp, anchor cable parts and an anchor cable guide pipe, wherein a steel cylinder is mounted at the lower surface of the upper clamp of the grouting pipe; an interlayer channel is formed downwards in the periphery wall of the steel cylinder; a three-way pipe communicated with the interlayer channel is mounted on the grouting pipe and at the lower surface of the upper clamp; a cylindrical piston of which the upper half part is mutually matched with the interlayer channel is mounted below the steel cylinder; upper guide positioning racks are correspondingly and rotationally connected with eight uniformly distributed pin shafts towards the lower sides, at the periphery of the lower end of the piston; a fixed ring is mounted between a grouting one-way valve and the lower clamp; eight uniformly distributed lower guide positioning racks are mounted on the fixed ring with the pin shafts respectively; and an expanding rod is connected between every two corresponding upper guide positioning rack and lower guide positioning rack. With the adoption of the anchor cable, the pulling resistance can be improved greatly; the pulling resistance can reach 600-1200KN after anchorage; and the anchor cable is applicable to both sand-gravel stratums and clay stratums.
