Description
Technical field
The invention belongs to the exhaust technology of Gas Outburst, especially and its a kind of outburst-prevention gas releasing pipe structure and its installation side
Method.
Background technology
With the fast development of coal production technical merit, coal production ability greatly improves, but with mining depth
Increase, mine gas occurrence condition is complicated, and gas emission also greatly increases, and is only difficult to solve gas exceeding limit by method of ventilation
Problem, mine gas become the important hidden danger for restricting Safety of Coal Mine Production, so it is imperative to carry out gas drainage under suction.In gas
During extraction, it is less than 0.04m for permeability coefficient2/(MPa2D) lower permeability seam, the gas that reach higher are taken out
Rate is put, adopting the time in advance cannot be less than 6~8 months, due to influence of the mining work activities to pressure from surrounding rock, cause gas extraction hole different
The deformation of degree, and then gas drainage pipe is subject to the pressure effect of country rock to make deformation, or even destroy, so as to influence gas extraction
Efficiency and coal production ability；In order to solve this problem, the prior art use outside gas drainage pipe increase woven wire or
Increase metal shell protection layer to improve the intensity of gas drainage pipe, be deformed to avoid gas drainage pipe；It is and such
Structure due to woven wire is added outside gas drainage pipe or add metal shell protection layer cause gas drainage pipe into
Originally it is significantly increased, and weight increase causes to carry and install inconvenience too much；And metal material is used in outside, due to taking out
The process of adopting takes more than 6~8 months, is placed on for a long time in drainage holes and is easy to cause metal layer corrosion, causes anti-pressure ability to reduce.
The content of the invention：
The technical problem to be solved in the present invention：A kind of outburst-prevention gas releasing pipe structure and its installation method are provided, it is existing to solve
The gas drainage pipe of technology is due to using of high cost caused by wire protective layer or metal shell protection layer increase compressive property
The too heavy caused carrying of high and weight and installation are inconvenient；And metal material is used in outside, since extraction process wants 6~8
More than a month, it is placed on for a long time in drainage holes and is easy to cause metal layer corrosion, cause anti-pressure ability to reduce.
Etc. technical problem.
Technical solution of the present invention：
A kind of outburst-prevention gas releasing pipe structure, it includes pvc pipe；Reinforcing pipe and trishores are fixed at intervals in pvc pipe inner wall
Frame.
Stiffening piece is fixed with three angles of the three-legged supporting frame, the stiffening piece is rubber, and width is 8-12 centimetres.
Stiffening piece is circular shape, and the arc surface is contacted with pvc pipe inner wall.
Equidistantly interval is fixedly mounted in pvc pipe for reinforcing pipe and three-legged supporting frame；And reinforcing pipe and three-legged supporting frame are handed over
Fork installation.
The spacing distance at equal intervals is 10-15 centimetres.
Reinforcing pipe is the rigid cylindrical pipe that length is 5~10cm, and surface is covered with rubber layer.
Three-legged supporting frame is the three-legged structure of rigid rod composition.
It is fixedly connected between pvc pipe by connecting tube；Pvc pipe is interference fitted with connecting tube.
A kind of installation method of outburst-prevention gas releasing pipe structure, it includes：
Step 1, by reinforcing pipe and three-legged supporting frame be equidistantly fixed on pvc pipe inner wall；And reinforcing pipe and three-legged supporting frame and PVC
Inside pipe wall is interference fitted；
Step 2, connected by connecting tube by each pvc pipe and fixed；And pvc pipe is interference fitted with connecting tube.
Beneficial effects of the present invention：
The present invention, with the non-deformability of Reinforced PVC pipe, has by being embedded in reinforcing pipe and three-legged supporting frame in pvc pipe inner wall
Cost is low, it is light-weight the advantages that, solve the gas drainage pipe of the prior art due to using wire protective layer or metal shell
Caused carrying too heavy with weight and installation with high costs caused by protective layer increase compressive property are inconvenient and in pvc pipe appearance
Face uses metal material, since extraction process takes more than 6~8 months, is placed on for a long time in drainage holes and is easy to cause metal layer corruption
Erosion, causes the technical problems such as anti-pressure ability reduction.
Brief description of the drawings：
Fig. 1 schematic structural views of the invention；
Fig. 2 is connecting pipe structure schematic diagram of the present invention.
Embodiment：
A kind of outburst-prevention gas releasing pipe structure, it includes pvc pipe 1, and 2 and three foot branch of reinforcing pipe is fixed at intervals in 1 inner wall of pvc pipe
Support 3.
Stiffening piece 5 is fixed with three angles of the three-legged supporting frame 3, the stiffening piece 5 is rubber, and width is 8-12 lis
Rice.Stiffening piece 5 is circular shape, and the arc surface is contacted with 1 inner wall of pvc pipe；Using circular shape, stiffening piece can be made more preferable
Contacted with pvc pipe inner wall, improve the anti-pressure ability of pvc pipe.
Equidistantly interval is fixedly mounted in pvc pipe 1 for reinforcing pipe 2 and three-legged supporting frame 3；And reinforcing pipe 2 and trishores
Frame 3 intersects installation.The spacing distance at equal intervals is 10-15 centimetres；Using such method, pvc pipe 46.7% can be improved
Compression strength above.Effectively solve the anti-pressure ability of pvc pipe.
It is fixedly connected between pvc pipe 1 by connecting tube 4；Pvc pipe 1 is interference fitted with connecting tube 4；PVC can arbitrarily be extended
The length of pipe, and can effectively be prevented during extraction using interference fit since gas pressure causes pvc pipe to come off.
Reinforcing pipe 2 is the rigid cylindrical pipe that length is 5~10cm, and surface is covered with rubber layer；Increase rubber layer on the one hand
The frictional force of reinforcing pipe 2 and pvc pipe internal diameter can be increased, make reinforcing pipe 2 not easily to fall off, while by the covering of rubber layer, can
Effectively to reduce the corrosion to reinforcing pipe 2.
