Abstract
The utility model provides a novel multi -functional stock, including the stock, the anchor of stock one end go into the country rock structure, stock end in the country rock structure is gone into in the anchor sets up anchor agent, the other end of stock sets up the helicitic texture, the nut passes through the helicitic texture with the stock to be connected, sets up the tray in one side of nut, cup joints water -swelling rubber on the stock of tray inboard, the tray hug closely the country rock structure. This device simple structure, simple to operate, swift, the low price, being favorable to sparingly, the fund just can adapt to complicated geological environment.
Description
Technical field
The utility model relates to the Roadway Support Technology field of coal mining, particularly relates to a kind of Multifunction anchor pole.
Background technology
Along with the continuous increase of the mining depth of China's coal-mine, the geostatic stress that roadway surrounding rock is subject to also constantly increases, and the shear stress that anchor pole is subject to is also increasing.Anchor pole often adopts in roadway support as a kind of the most frequently used supporting means, the loading characteristic of common bolt be anchor pole distortion must with the deform in coordination of Rock And Soil, if but the shearing strain of rock mass has exceeded the maximum deformation quantity that anchor pole allows, cut off the phenomenon of inefficacy because anchor pole occurs comparatively greatly in shearing strain by shear stress with regard to there will be.The area of rich groundwater, water can flow in lining cutting layer by armature boring, reduces the stability of supporting.
The anchor pole of present use is varied, mostly can not adapt to complicated geological environment, not consider that anchor pole is subject to this situation of shear stress, or do not have the anchor pole well can tackling shear stress.Research about various novel anchor rod is carried out a lot of both at home and abroad in recent years, also have developed a series of product, but in general, existing various anchor pole still exists problems, and main manifestations is: complex structure, processing inconvenience and high in cost of production.
Utility model content
For the deficiencies in the prior art, the utility model proposes a kind of Multifunction anchor pole, solve complex structure in prior art, processing inconvenience, cost high and the problem of complicated geological environment can not be adapted to.
The technical solution of the utility model is achieved in that
A kind of Multifunction anchor pole, comprise anchor pole, described anchor pole one end anchoring enters in surrounding rock structure, the termination point of anchor rod entered in surrounding rock structure in anchoring arranges Anchor Agent, the other end of anchor pole arranges helicitic texture, and described nut is connected by helicitic texture with anchor pole, arranges pallet in the side of nut, anchor pole inside pallet is socketed hydro-expansive rubber, and surrounding rock structure is close to by described pallet.
Described Anchor Agent is wrapped in the termination, side of anchor pole.
Anchor pole inside described pallet and between Anchor Agent is all provided with hydro-expansive rubber.
Described pallet is the steel pallet of high strength and high rigidity.
This device simple structure, easy for installation, quick, low price, is conducive to saving fund.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the view before the utility model expands.
Fig. 2 is the view after the utility model water-swellable.
Wherein, 1. anchor pole, 2. nut, 3. pallet, 4. hydro-expansive rubber, 5. Anchor Agent, 6. surrounding rock structure.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1, as shown in Figure 1 and 2, the utility model provides a kind of Multifunction anchor pole, comprises anchor pole 1, and described anchor pole 1 one end anchoring enters in surrounding rock structure 6, the termination of the anchor pole entered in surrounding rock structure 6 in anchoring arranges Anchor Agent 5, the other end of anchor pole 1 arranges helicitic texture, and described nut 2 is connected by helicitic texture with anchor pole 1, arranges pallet 3 in the side of nut 2, anchor pole 1 inside pallet 3 is socketed hydro-expansive rubber 4, and surrounding rock structure 6 is close to by described pallet 3.
Preferably, described pallet 3 is the steel pallet 3 of high strength and high rigidity, adopts this material to enhance the intensity of pallet, prevents pallet to be out of shape, add the application life of anchor rod pallet board.
Operating principle of the present utility model is as follows: the position, termination stretching into anchor pole 1 in surrounding rock structure 6 arranges Anchor Agent 5, increase the anchoring strength of anchor pole 1 and surrounding rock structure 6, by being socketed hydro-expansive rubber 4 on anchor pole 1, the elastic buffer shear stress making hydro-expansive rubber had upon inflation is to the impact of anchor pole, and the elasticity of rubber itself can make impact slow down further; Hydro-expansive rubber expansion force suitably can increase the anchored force of anchor pole; Hydro-expansive rubber also can block the water seepage hole on drill hole wall after expanding, can prevent the water in deep, rock stratum from penetrating into tunnel lining cutting layer by armature boring, improves the stability of supporting.
Embodiment 2, described Anchor Agent 5 is wrapped in the termination, side of anchor pole 1, and other structures are with embodiment 1, and this setting further enhancing the anchoring strength of anchor pole and surrounding rock structure, effectively improve the stability of supporting.
Embodiment 3, anchor pole 1 inside described pallet 3 and between Anchor Agent 5 is all provided with hydro-expansive rubber 4, other structures are with embodiment 1, by this arrange strengthen further hydro-expansive rubber expand after anchored force to anchor pole, effectively prevent the water in deep, rock stratum from penetrating into tunnel lining cutting layer by armature boring, improve supporting stability further.
This patent has following innovation:
(1) impact of shear stress to anchor pole can be slowed down.Can slow down the impact of shear stress to anchor pole after being enclosed within the hydro-expansive rubber expansion of anchor pole outside, the elasticity of rubber itself can make the impact of shear stress to anchor pole slow down further.
(2) suitably anchored force can be increased.Anchor pole generally adopts end anchorage, and after the hydro-expansive rubber water-swellable of this device, suitably can increase the anchored force of anchor pole.
(3) there is water blockoff antiseepage function.The hydro-expansive rubber be enclosed within anchor pole has water-proof function, can prevent the water in deep, rock stratum from penetrating into tunnel lining cutting layer by armature boring, improves the stability of supporting.
(4) easy for installation, quick.In rockbolt installation process, general installation environment is poor, and this device simple structure is easy for installation, quick.
(5) low price, is conducive to saving fund.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
