Description
Technical field
This utility model belongs to the mash gas pumping drilling hole sealing device in colliery, relates to a kind of split type pouch fluid filling hole sealing device with pressure.
Background technology
At present, the mash gas pumping drilling hole packer in colliery, it is that a slip casting plugging bag is fixed with tightening ring packing respectively in front-end and back-end in the circumferential wall of a Grouting Pipe, in Grouting Pipe parallel beneath, one coal seam Grouting Pipe is installed, plugging bag before Grouting Pipe and coal seam Grouting Pipe hermetically passing simultaneously, after the insertion of Grouting Pipe rear end in plugging bag, front and back, the slip casting in plugging bag is provided with grout outlet, explosion valve it is provided with at grout outlet, this hole packer is in use, after front and back plugging bag fills slurry, explosion Valve breakage, Grouting Pipe slip casting terminates, coal seam Grouting Pipe starts slip casting subsequently, the hole packer of prior art, after coal seam Grouting Pipe starts slip casting, rib pressure increases, front plugging bag is easily and the long-living gap of rib, thus cause the closure Quality Down of front plugging bag, affect work efficiency.
Utility model content
For the defect overcoming prior art to exist, the technical scheme that this utility model provides is as follows:
A kind of split type pouch fluid filling hole sealing device with pressure, including front pouch, rear pouch and pouch Grouting Pipe, after described pouch Grouting Pipe runs through front pouch, its end is communicated in rear pouch, pouch Grouting Pipe is positioned at the part of front pouch and rear pouch and is respectively arranged with grout outlet, grout outlet in front pouch is provided with explosive valve one, grout outlet in rear pouch forms confined space between being provided with after explosive valve two, front pouch and rear pouch fill slurry；It is arranged with coal seam Grouting Pipe in parallel with described pouch Grouting Pipe；After described coal seam Grouting Pipe runs through front pouch, its end is communicated in described confined space；Coal seam Grouting Pipe is positioned at the part of front pouch and is provided with persistently benefit slurry hole, and the end of coal seam Grouting Pipe is provided with explosive valve three.
Described front pouch, rear pouch are canvas pouch.
Described pouch Grouting Pipe is provided with snap joint.
Described front pouch and rear pouch pass through dead ring fit sealing with pouch Grouting Pipe and Grouting Pipe coupling part, coal seam.
Beneficial effect: be equipped with explosive valve at the injected hole of pouch Grouting Pipe and grouting port, start to pouch slip casting, after outer end pouch and inner pouch reach to a certain degree with rib pressure, explosive valve works, pouch Grouting Pipe stops slip casting, coal seam Grouting Pipe starts slip casting, rib is squeezed and expands to surrounding, between outer end pouch and rib, pressure diminishes, plugging effect is caused to decline, at this moment, in the Grouting Pipe of coal seam, injected hole starts slip casting, until outer end pouch completely encloses with rib, additionally, described coal seam Grouting Pipe end is provided with explosive valve, slip casting thing is filled into a certain degree, when rib pressure reaches certain value, the explosive valve work of coal seam Grouting Pipe end, coal seam Grouting Pipe stops slip casting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, pouch before 1, pouch after 2,3 pouch Grouting Pipe, 4 grout outlets, 5 explosive valves one, 6 snap joints, 7 explosive valves two, 8 coal seam Grouting Pipe, 9 persistently mend slurry hole, 10 explosive valves three, 11 dead rings.
Detailed description of the invention
nullOne split type pouch fluid filling hole sealing device with pressure as shown in Figure 1，Including front pouch 1、Rear pouch 2 and pouch Grouting Pipe 3，Front pouch 1、Rear pouch 2 is canvas pouch，After pouch Grouting Pipe 3 runs through front pouch 1, its end is communicated in rear pouch 2，Pouch Grouting Pipe 3 is positioned at the part of front pouch 1 and rear pouch 2 and is respectively arranged with grout outlet 4，The grout outlet 4 in pouch Grouting Pipe 3 in front pouch 1 is provided with explosive valve 1，Pouch Grouting Pipe 3 end is provided with snap joint 6，The grout outlet 4 in pouch Grouting Pipe 3 in rear pouch 2 is provided with explosive valve 27，Front pouch 1 and rear pouch 2 are filled and are formed confined space between after slurry，The side of pouch Grouting Pipe 3 is arranged with coal seam Grouting Pipe 8 in parallel，After coal seam Grouting Pipe 8 runs through front pouch 1, its end is communicated in described confined space，Coal seam Grouting Pipe 8 is positioned at the part of front pouch 2 and is provided with persistently benefit slurry hole 9，The end of coal seam Grouting Pipe 8 is provided with explosive valve 3 10，Front pouch 1 and rear pouch 2 pass through dead ring 11 fit sealing with pouch Grouting Pipe 3 and coal seam Grouting Pipe 8 coupling part.
nullEmbodiment: this device is put into the boring on coal seam，Rear pouch is positioned at boring inner end，Front pouch is positioned at boring outer end，Then pouch Grouting Pipe starts slip casting，Coal seam pressure is reached to a certain degree by current pouch and rear pouch，Front pouch and rear pouch play sealing of hole effect，Explosive valve in pouch Grouting Pipe work in the explosive valve being positioned in snap joint and front pouch，Pouch Grouting Pipe stops slip casting，Confined space is formed between front pouch and rear pouch，At this moment，Coal seam Grouting Pipe is started working，Start confined space is carried out slip casting，When in confined space, coal seam is reached to a certain degree by serosity，Boring expands outwardly，Pressure between front pouch and coal seam is caused to reduce，Sealing of hole effect is deteriorated，Now the slurry of the benefit in the Grouting Pipe of coal seam hole starts front pouch slip casting，When closing serosity in space and the pressure in coal seam and front pouch being reached certain value to the pressure in coal seam，The explosive valve work of coal seam Grouting Pipe end，Coal seam Grouting Pipe quits work.
