Description

Arched surrounding rock supporting net

Technical Field

The utility model relates to an apparatus technical field is consolidated to the country rock, especially relates to an arch country rock supporting net.

Background

When using the pipe seam formula stock to consolidate the country rock, need cooperate the supporting wire net, can prevent that the rocky piece on the country rock etc. from dropping, influence the reinforcement effect.

When the surrounding rock is reinforced, the supporting net is firstly covered on the surface of the surrounding rock, and then the tubular anchor rod is installed.

When the arch-shaped surrounding rock (namely, a culvert, a mine tunnel and the like) is reinforced, the two sides of the supporting net can be fixed only by adopting a row of pipe seam type anchor rods on the supporting net at the lower ends of the two sides of the arch, so that a large number of pipe seam type anchor rods are wasted.

SUMMERY OF THE UTILITY MODEL

To the not enough that exists among the prior art, the utility model provides an arch country rock supporting net, it has solved among the prior art and has fixed the both sides of supporting net and need a large amount of tube seam formula stock, causes extravagant problem.

According to an embodiment of the utility model, an arch-shaped surrounding rock supporting net comprises a body, wherein both sides of the body are fixedly connected with fixing plates; the fixing plate comprises an embedding part embedded into the surrounding rock and a fixing part far away from the surrounding rock, and the body is connected to the fixing part; also comprises a plurality of ground nails which are fixed on the fixed part and vertically penetrate into the surrounding rock.

Among the above-mentioned technical scheme, adopt the fixed plate to fix in the both sides of strutting the net body, and in some embedding of fixed plate to the country rock, another part is fixed through ground nail and arched bottom country rock, can play good fixed effect.

Compared with the prior art, the utility model discloses following beneficial effect has:

replace a plurality of pipe seam formula stock with the fixed plate, avoided the waste, simultaneously, partly imbed the surrounding rock with the fixed plate in, another part adopts the ground nail to consolidate, can improve the stability of supporting the net both sides, and then has strengthened the effect of strutting the reinforcement surrounding rock.

Drawings

Fig. 1 is a schematic view of the overall structure of an embodiment of the present invention during installation and use;

FIG. 2 is an enlarged view of a portion A of FIG. 1;

in the above drawings: the wall rock 1, the body 2, the fixed plate 3, the embedding part 4, the fixed part 5, the ground nail 6, the protection plate 7, the clamping part 8, the mounting plate 9, the arc-shaped plate 10, the screw 11, the nailing part 12, the cap body 13 and the concave groove 14.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, the embodiment provides an arched surrounding rock supporting net, which includes a body 2 attached to an arched surface of a surrounding rock 1, wherein two sides of the body 2 are fixedly connected with fixing plates 3 respectively located at two sides of the bottom of the arch; the fixed plate 3 comprises an embedded part 4 embedded in the surrounding rock 1 and a fixed part 5 far away from the surrounding rock 1, and the body 2 is connected to the fixed part 5; still including fixing on fixed part 5 and penetrate a plurality of ground nails 6 in the country rock 1 perpendicularly, directly nail into the 1 bottom of country rock through ground nail 6, consolidate fixed plate 3.

In the embodiment, the two sides of the supporting net body 2 are fixed by the fixing plates 3, one part of the fixing plate 3 is embedded into the surrounding rock 1, the other part of the fixing plate 3 is fixed with the arched bottom surrounding rock 1 through the ground nails 6, and the two ends of the fixing plate 3 are fixed, so that a good fixing effect can be achieved;

the supporting net that this embodiment provided replaces a plurality of pipe seam formula stocks with fixed plate 3, has avoided the waste of pipe seam formula stock, simultaneously, with the partly embedding of fixed plate 3 in country rock 1, another part adopts ground nail 6 to consolidate, can improve the stability of supporting net both sides, and then has strengthened the effect of strutting and consolidating country rock 1.

Preferably, in order to prevent rats and the like from gnawing the supporting net, the supporting net further comprises a protection plate 7 detachably mounted on the fixing portion 5, one side of the protection plate 7 is tightly attached to the body 2, the other side of the protection plate is a smooth surface, the smooth surface can prevent rats from climbing upwards, and the rats are prevented from gnawing the body 2.

Preferably, the protection plate 7 comprises an arc-shaped plate 10 with a clamping part 8 arranged at the lower end and a mounting plate 9 arranged at the upper end of the arc-shaped plate 10, a clamping groove for clamping the clamping part 8 is arranged on the fixing part 5, and a plurality of screws 11 penetrating through the body 2 and inserted into the surrounding rock 1 are in threaded connection with the mounting plate 9; wherein, the upper end of the mounting plate 9 is smoothly transited with the body 2; the protection plate 7 can be conveniently disassembled and assembled by the arrangement, and normal installation and maintenance of the support net are not influenced.

Preferably, the ground nail 6 comprises a nail-in part 12 and a cap body 13, a concave groove 14 for accommodating the cap body 13 is concavely arranged on the fixing part 5, and the depth of the concave groove 14 is greater than the thickness of the cap body 13, so that the ground nail 6 is not exposed outside the fixing plate 3 after being installed with the supporting net, and meanwhile, the concave groove 14 can be filled with slurry and the like, so that the ground nail 6 is invisible, and misoperation of non-working personnel is prevented.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
