Abstract
The utility model discloses a collecting space area gas drainage pipeline, establish the plastic tubing outside metal pipeline including metal pipeline with the cover, be provided with the rubber layer between metal pipeline and the plastic tubing, be provided with between rubber layer and the metal pipeline and be used for being viscose layer together with metal pipeline and rubber layer bonding, the inner wall and the rubber laminating of plastic tubing close, length homogeneous phase of metal pipeline, rubber layer, viscose layer and plastic tubing etc, metal pipeline and plastic tubing are the pipe. The utility model has the advantages of simple structure and reasonable design and the practicality is strong, can prevent that slump rock and metal pipeline collision and friction from producing the spark, effectively slows down the slump rock simultaneously to the surge pressure of gas drainage pipeline, and it is convenient to make, low in manufacturing cost.
Description
Technical field
The utility model belongs to gas pumping technical field, is specifically related to a kind of goaf gas extraction pipeline.
Background technology
Along with improving constantly of the modernization of coal in China industry and technical level, mine starts to progress into the deep mining stage, with appearance is then that ore deposit pressure manifests more obvious, roof break and crack field scope strengthen, the problem such as gas and water burst is more outstanding, the pipe problems such as to draw out methane becomes increasingly conspicuous: goaf top plate caves in, pipe bending is usually caused to be out of shape and useful cross section is reduced, rock and metallic conduit collision friction produce spark simultaneously, the gas gathered with residual coal and the goaf of weathering meets, very easily to ignite even explosion accident, the colliery security of the lives and property in serious threat.And owing to being subject to the restriction of down-hole geological conditions, plastic or other material temporarily also alternative metals cannot be applied to down-hole, therefore better carry out and problem demanding prompt solution is become to the Protective strategy of metallic conduit.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of goaf gas extraction pipeline is provided, its structure is simple, reasonable in design and practical, can prevent slump rock and metallic conduit collision friction from producing spark, effectively slow down the surge of slump rock to gas pumping pipeline simultaneously, easily manufactured, low cost of manufacture.
For achieving the above object, the technical solution adopted in the utility model is: a kind of goaf gas extraction pipeline, it is characterized in that: comprise metallic conduit and be set in the plastic pipe outside metallic conduit, rubber layer is provided with between described metallic conduit and plastic pipe, described rubber layer be provided with for the adhesive-layer together with metallic conduit is bonded as with rubber layer between metallic conduit, the inwall of described plastic pipe and rubber layer are fitted, the identical length etc. of described metallic conduit, rubber layer, adhesive-layer and plastic pipe, described metallic conduit and plastic pipe are pipe.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: described rubber layer is neoprene layer.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: described plastic pipe is pvc pipe.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: described adhesive-layer is industrial glue layer.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: described metallic conduit is steel pipe.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: the external diameter of described metallic conduit is 50mm ~ 300mm, and the wall thickness of described metallic conduit is 4mm ~ 10mm.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: the thickness of described rubber layer is 5mm ~ 10mm.
Above-mentioned a kind of goaf gas extraction pipeline, is characterized in that: the wall thickness of described plastic pipe is 3mm ~ 5mm.
The utility model compared with prior art has the following advantages:
1, the utility model structure is simple, reasonable in design and practical.
2, rubber layer resilience of the present utility model, acid resistance better, can slow down the impact of ambient pressure to metallic conduit, prevent metallic conduit from corroding by down-hole sour gas and acid water simultaneously; Plastic pipe has high strength, the characteristic such as fire-retardant, when rock falls, both can effectively prevent slump rock and metallic conduit collision friction from producing spark and causing gas to ignite and explosion phenomenon, metallic conduit compressive deformation can be reduced again, only need change plastic pipe just reusable simultaneously, improve the recovery utilization rate of gas pumping pipeline.
3, the utility model is easily manufactured, and processing cost is low, is convenient to installation and transportation.
Below by drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
As shown in Figure 1 to Figure 3, the plastic pipe 3 that the utility model comprises metallic conduit 1 and is set in outside metallic conduit 1, rubber layer 2 is provided with between described metallic conduit 1 and plastic pipe 3, described rubber layer 2 be provided with for the adhesive-layer 4 together with metallic conduit 1 is bonded as with rubber layer 2 between metallic conduit 1, inwall and the rubber layer 2 of described plastic pipe 3 are fitted, the identical length etc. of described metallic conduit 1, rubber layer 2, adhesive-layer 4 and plastic pipe 3, described metallic conduit 1 and plastic pipe 3 are pipe.
In the present embodiment, described rubber layer 2 is neoprene layer.
In the present embodiment, described plastic pipe 3 is pvc pipe.
In the present embodiment, described adhesive-layer 4 is industrial glue layer.
In the present embodiment, described metallic conduit 1 is steel pipe.
In the present embodiment, the external diameter of described metallic conduit 1 is 50mm ~ 300mm, and the wall thickness of described metallic conduit 1 is 4mm ~ 10mm.
In the present embodiment, the thickness of described rubber layer 2 is 5mm ~ 10mm.
In the present embodiment, the wall thickness of described plastic pipe 3 is 3mm ~ 5mm.
During use, one end of gas pumping pipeline is placed in goaf 5, the other end of gas pumping pipeline is placed in stope drift active workings 6 and can uses.In the utility model, metallic conduit 1 mainly plays load-bearing effect, and rubber layer 2 resilience, acid resistance are better, can slow down the impact of ambient pressure to metallic conduit 1, prevent metallic conduit 1 from corroding by down-hole sour gas and acid water simultaneously.Plastic pipe 3 has high strength, the characteristic such as fire-retardant, when rock falls, both can effectively prevent slump rock and metallic conduit 1 collision friction from producing spark and causing gas to ignite and explosion phenomenon, metallic conduit 1 compressive deformation can be reduced again, only need change plastic pipe 3 just reusable simultaneously, improve the recovery utilization rate of gas pumping pipeline.During actual fabrication, rubber layer 2 can carry out cutting according to the difference of metallic conduit 1 diameter, then uses industrial glue to adhere to outside metallic conduit 1 by rubber layer 2, is finally inserted in the plastic pipe 3 of suitable dimension.
