Described anchor cable expansion sleeve 2 has multiple strip gab axial along steel strand wires 4 near anchor head 1 one end.
The outer surface of described expansion sleeve 2 has external screw thread, in order to increase the frictional force of itself and hole wall.
Work process of the present utility model is:
Steel strand wires 4 already equipped with expansion sleeve 2 and anchor cable sleeve pipe 3 are put into (anchor cable sleeve pipe 3 is used for propping up expansion sleeve 2, backing plate 6) in the boring 5 being drilled, then by tensioning equipment, steel strand wires 4 are pulled outward, anchor head 1 is drawn in anchor cable expansion sleeve 2, expansion sleeve 2 is by distending, make its distension whole Kong Bingyu hole wall form frictional force self-locking, the most just improve the prestressing force of anchor cable.Afterwards, sleeve pipe 3 can be pulled down and repeat to be used in other anchor cables.
The beneficial effects of the utility model are:
1, the New Anchor Cable structure of a kind of big side slope cable bolting is provided, it is achieved while high pre-stress, ensure that the anchor force of anchor cable；
2, the processing of anchor cable expansion sleeve is simple, the reusable cost-effective high financial profit of anchor cable sleeve pipe；
3, the sleeve pipe follow-up boring provided in installation process, it is ensured that sleeve pipe is put into the angle of anchor cable and kept consistent with bore angle.
