Abstract
The utility model relates to a kind of self-drilling hollow grouting cable anchor, comprise: anchor cable front end, Bower Anchor cable body, Grouting Pipe, slurry outlet, supporting plate, billet, lockset and stop grouting plug, the external surface of anchor cable front end is provided with screw thread, slurry outlet is evenly distributed in Grouting Pipe tube wall, and anchor cable is provided with supporting plate, billet and lockset near wall place.The beneficial effects of the utility model are: structure is simple, certainly can drill into country rock, easy for installation; Anchor cable front end can adopt resin anchoring, and interlude can adopt slip casting anchoring, thus achieves the resin anchoring of anchor cable and the combination of slip casting anchoring, and carry out modification to country rock, anchoring effect is good.
Description
Technical field
The utility model relates to a kind of mine grouting cable anchor, particularly a kind of self-drilling hollow grouting cable anchor gob side entry retaining tunnel being carried out to anchor pouring reinforcement.
Background technology
At present, edge air gallery technology is widely used in Chinese large-sized mine, simultaneously, along with the minimizing day by day of superficial part coal resources, colliery enters deep mining state successively, because Coal Exploitation is dark and the increase of geostatic stress, gob side entry retaining strata behavior analysis of roadway manifests usually comparatively violent, country rock is comparatively broken, anchor is poor, anchor pole cannot give full play to its performance, only have by anchor cable Tunnel Pressure to be delivered in stable rock stratum, deep and could control roadway deformation with stable, and use grouting cable anchor anchoring can be combined with slip casting, while top board active enforcement, modification is carried out to country rock, save operation, anchoring effect is better.
Utility model content
The purpose of this utility model overcomes existing anchor pole, anchor cable to the weak point of deep gob side entry retaining roadway support, provides one to be convenient to install, the self-drilling hollow grouting cable anchor that supporting effect is good.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of self-drilling hollow grouting cable anchor, comprise: anchor cable front end, Bower Anchor cable body, Grouting Pipe, slurry outlet, supporting plate, billet, lockset and stop grouting plug, the external surface of anchor cable front end is provided with screw thread, slurry outlet is evenly distributed in Grouting Pipe tube wall, and anchor cable is provided with supporting plate, billet and lockset near wall place.
The outer surface thread degree of depth of described anchor cable front end is 11 ~ 12mm, and pitch is 20 ~ 22mm.
Described Bower Anchor cable body is entwined by eight high strength steel strands.
Described slurry outlet spacing is 90 ~ 100mm.
Therefore, the beneficial effects of the utility model are: structure is simple, certainly can drill into country rock, easy for installation; Anchor cable front end can adopt resin anchoring, and interlude can adopt slip casting anchoring, thus achieves the resin anchoring of anchor cable and the combination of slip casting anchoring, and carry out modification to country rock, anchoring effect is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cross section structure figure in Fig. 1.
In figure, 1-anchor cable front end, 2-Bower Anchor cable body, 3-Grouting Pipe, 4-slurry outlet, 5-supporting plate, 6-billet, 7-lockset, 8-stop grouting plug, 9-steel strand.
Detailed description of the invention
The technical characteristic realized to make the utility model with reach object and be easy to understand, below in conjunction with accompanying drawing, set forth the utility model further.
As shown in Figure 1, a kind of self-drilling hollow grouting cable anchor, comprise: anchor cable front end 1, Bower Anchor cable body 2, Grouting Pipe 3, slurry outlet 4, supporting plate 5, billet 6, lockset 7 and stop grouting plug 8, the external surface of anchor cable front end 1 is provided with screw thread, slurry outlet 4 is evenly distributed in Grouting Pipe 3 tube wall, and Bower Anchor cable body 2 is provided with supporting plate 5, billet 6 and lockset 7 near wall place.As shown in Figure 2, Bower Anchor cable body 2 is entwined by eight high strength steel strands 9.
Adopt self-drilling hollow grouting cable anchor of the present utility model, directly can rotate into soft-rock tunnel, be convenient to install; Before installation anchor cable, resin explosive roll is put into boring, thus anchor cable front end can realize resin anchoring, after installing anchor cable, then carry out slip casting, thus interlude can realize slip casting anchoring, these two kinds of anchorage styles combine, and can strengthen the anchoring effect to country rock, thus make tunnel more stable.
