Having the features such as intensity is low, cementing properties is poor, after roadway excavation, be easily caused country rock and produce large deformation, supporting construction lost efficacy.Currently used
The commonly used steel strand wires of cable body of anchor cable, although its Support Resistance is higher, but owing to the elongation percentage of steel strand wires is relatively low, at Soft Rock Roadway
Under road large scale deformation, easily cause anchor cable disrumpent feelings, thus cannot continue to provide effective Support Resistance, to soft to country rock
The safety in rock gangway road brings certain harm.Additionally, in existing cable bolting work progress, use anchor cable by Anchor Agent
Powder stick advances foot of hole, and in progradation, Anchor Agent powder stick tends to come off or skid off, thus causes the anchoring of anchor cable
Poor effect, loses and should have supporting effect, the safety in serious threat tunnel.The most how to increase the anchor of soft-rock tunnel stream line
Gu effect, farthest playing anchor cable effect, this technical barrier is badly in need of solving.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of pressure-release anchor cable, and this pressure-release anchor cable can be to Soft Rock Roadway
Road supporting can play good effect, allows pressure device by arranging on anchor cable, can effectively solve soft-rock tunnel big
The powerful external force produced in deformation process causes the problem that anchor cable occurs fracture；Meanwhile, utilize at anchorage cable anchoring section and free segment
Junction back-up ring is set, can utilize easily anchor cable by Anchor Agent powder stick advance foot of hole, it is ensured that Anchor Agent medicine
Volume will not skid off, and improves the anchoring effect of anchor cable, it is ensured that the country rock safety of Soft Rock Drifts At Coal.
A kind of pressure-release anchor cable of the present utility model is realized by following technical proposals:
A kind of pressure-release anchor cable, including cable body, the pallet being located on cable body, and is located at the lockset of cable body afterbody.Cable body bag
