Description
Technical field
The utility model belongs to down-hole coal bed gas drainage technical field more particularly to a kind of novel bag type paste hole packer.
Background technique
The green pool coal mine in Guizhou Province Dafang County belongs to coal and gas prominent coal mine, in order to realize safety in production, ensures coalman
The life and health of people needs to carry out extraction to the gas in coal seam to be particularly easy to drilling gas occur during mash gas extraction
Borehole sealing Resolving probiems are fallen for shortening the gas drainage time, are mentioned by hole poorly sealed the problem of leading to extraction inefficiency
High extraction compliance rate has very real meaning.Existing bag type paste hole packer there are some defects, such as pouch cannot be tight
The gas that close fitting extraction bores when leading to pouch to the no enabling capabilities of drilling, slip casting in pouch cannot be completely exhausted out, slip casting
When pressure cause pouch to rupture greatly very much, this all can cause gas drainage unqualified, for safety in production leave hidden danger.Therefore, it invents
A kind of practical and convenient wrapper is necessary.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of novel bag type paste hole packer, technical solution
Are as follows:
Construction drill (1) in coal body is installed gas drainage pipe (2) in drilling (1), is rolled up on gas drainage pipe (2)
Around two pouches (3), in interior bottom installation Grouting Pipe (9) of drilling (1), slurry recovering tube (4) are installed in drilling (1) inner top, it is described
Slurry recovering tube (4) and Grouting Pipe (9) and gas drainage pipe (2) are wound onto pouch (3), and Grouting Pipe (9) and slurry recovering tube (4)
End protrude into one of pouch (3), in pouch (3) slurry recovering tube (4) and Grouting Pipe (9) on equipped with inlet non return check valve
(5), controllable explosive valve (10) are installed on Grouting Pipe (9) and between two pouches (3), on slurry recovering tube (4) and at two
Inlet non return check valve (5) are installed between pouch (3), one end of slurry recovering tube (4) is connected with pressure gauge (6), one end of Grouting Pipe (9) and
Wind-driving grouting pumps (7) and is connected, and wind-driving grouting pump (7) is connected with slurry bucket (8).
Further, the pouch (3) is bilayer, and internal layer is terylene filter cloth, and outer layer is fire retardant.
Further, the slurry recovering tube (4) is identical as the diameter of Grouting Pipe (9).
Further, the bearing capacity of the inlet non return check valve (5) is less than the bearing capacity of controllable explosive valve (10).
The utility model has the following beneficial effects: the utility model is a kind of novel bag type paste hole packer, pouch is by dual
Material is made, and quality is solid, be not susceptible to grouting pressure it is excessive when the broken situation of pouch, while pouch can will be extra
Moisture filter, only maintain slurry, the gas in pouch can be discharged in slurry recovering tube, prevent in bag that there are gases, fill pouch
Consolidation is filled out, meets the needs of borehole sealing.Slurry recovering tube is connected to pressure gauge, and the pressure in concern pouch that can be close is accomplished
The visualization of pouch pressure.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
As shown, 1 drilling, 2 gas drainage pipes, 3 pouches, 4 slurry recovering tubes, 5 inlet non return check valves, 6 pressure gauges, 7 pneumatic notes
Stock pump, 8 slurry buckets, 9 Grouting Pipes, 10 controllable explosive valves.
Specific embodiment
The utility model is a kind of novel bag type paste hole packer, and gas is installed in drilling 1 in construction drill 1 in coal body
Drainage tube 2, further includes Grouting Pipe 9 and slurry recovering tube 4, successively two pouches of sealed set outside the Grouting Pipe 9 and slurry recovering tube 4
3, Grouting Pipe 9 and slurry recovering tube 4 are both provided with inlet non return check valve 5 in two pouches 3, and the Grouting Pipe 9 between pouch 3 is arranged
There is controllable explosive valve 10, slurry recovering tube 4 is connected to two pouches 3 and is connected with pressure gauge 6.The pouch 3 is double layer material production,
Interior layer material is terylene filter cloth, and cladding material is fire retardant.The pouch 3 is all to take out first wound on gas when in use
It adopts on pipe 2.Two pouches 3 are connected to by Grouting Pipe 9 with slurry recovering tube 4.The Grouting Pipe 9 and slurry recovering tube 4 all penetrates
Two pouches 3 are without being pierced by.Slurry is placed in slurry bucket 8, slurry bucket 8 is connected with wind-driving grouting pump 7, and the Grouting Pipe 9 is to pass through
Wind-driving grouting pumps 7 toward the inner injection slurry of pouch 3.The diameter of the slurry recovering tube 4 is consistent with 9 diameter of Grouting Pipe.Described is unidirectional
The bearing capacity of non-return valve 5 is less than the bearing capacity of controllable explosion valve 10.
When the utility model is used, first by one of pouch on gas drainage pipe, another pouch root
According to the actual requirement at scene, selects suitably distance to wind second pouch again, the two sides of pouch are inserted into respectively then and are had
The Grouting Pipe and slurry recovering tube of inlet non return check valve, slurry recovering tube connects pressure gauge by polymer rubber pipe, while wind-driving grouting being pumped
It is connect with Grouting Pipe, among the connection of entire hole packer again deeply drills gas drainage pipe after completing.It is pumped by wind-driving grouting
Common rapid hardening early-strength slurry is injected into Grouting Pipe, the type slurry is cheap and easy to get, can quick solidification, and be not easy to plug pipe
Extraction efficiency is improved on road.Slurry pass through first inlet non return check valve and meanwhile inject two pouches in, with injection slurry increasingly
More, pouch starts to expand, and pouch, which can come out the moisture filter in slurry, is not lost slurry but, and air can also be by returning
Pipe discharge is starched, after being full of slurry in bag, pouch can be fitted closely with drilling, drawing-off gas pipe, construct a closed small ring
Border.Continue to inject slurry, when the pressure of pressure gauge shows 1MPa, the controllable explosive valve of Grouting Pipe will be opened, and slurry passes through
Explosion valve enters the closed area between two pouches, blocks to borehole space, and gas therein also can be by returning slurry
Pipe discharge is not in the insufficient situation of filling.When pressure gauge shows that the time of 1.2MPa stops injection slurry, due to unidirectional
The case where presence of non-return valve is not in overfall.
Specific description is carried out to the application of the invention above, but the invention is not limited to the above institute
State, be familiar with one of skill in the art on the premise of not violating the inventive spirit of the present invention and can also make various equivalent changes or
Replacement, these equivalent changes or replacement are all included in the scope defined by the claims of the present application.
