But, adopt prior art, can realize down to hole, lateral aperture sealing of hole, but when upward hole sealing of hole, due to the Action of Gravity Field of cement paste and water self, can by good for the hypomere shutoff of upward hole, with two stifled note hole packers, twice shutoff is carried out to upward hole again, cause complex structure, high cost, be difficult to carry out marketing.
Utility model content
The utility model embodiment provides a kind of upper to hole packer, and structure is simply, and simple to operate, and shutoff efficiency is high, reduces the cost of labor of material cost and manufacture, installation.
The utility model embodiment provide a kind of on to hole packer, comprising: sealed pouch, Grouting Pipe and gas drainage pipe;
Described sealed pouch winding forms trepanning;
Described gas drainage pipe is located in described trepanning, is fixedly connected with described sealed pouch;
Described Grouting Pipe sealing is located in described sealed pouch;
The described Grouting Pipe part penetrated in described sealed pouch is provided with the first explosive valve, and the described Grouting Pipe part be positioned at outside described sealed pouch is provided with the second explosive valve.
As mentioned above, also comprise to hole packer on: splicing tape;
Described splicing tape glue be located at described trepanning the port of export outside, described sealed pouch and described gas drainage pipe are adhesively fixed.
As mentioned above, the both sides of described sealed pouch are provided with splicing tape, and after described sealed pouch winding forms trepanning, described sealed pouch, inside described trepanning, is adhesively fixed on the outer wall of described gas drainage pipe by described splicing tape.
As mentioned above, the one side of described splicing tape is provided with colloid.
As mentioned above, described sealed pouch is rubber pouch.
To hole packer in the utility model embodiment, by arranging a sealed pouch, when upward hole shutoff, take full advantage of the Action of Gravity Field of slurries self, deposit downwards, thus make the hypomere shutoff of upward hole good, structure is simple, and simple to operate, shutoff efficiency is high, reduces the cost of labor of material cost and manufacture, installation.

Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is 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 making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the structural representation to hole packer embodiment one on the utility model, as shown in Figure 1, the device of the present embodiment can comprise: sealed pouch 10, Grouting Pipe 20 and gas drainage pipe 30, wherein, sealed pouch 10 reels and forms trepanning 11, gas drainage pipe 30 is located in described trepanning 11, be fixedly connected with described sealed pouch 10, described Grouting Pipe 20 sealing is located in described sealed pouch 10, described Grouting Pipe 20 part penetrated in described sealed pouch 10 is provided with the first explosive valve 21, and described Grouting Pipe 20 part be positioned at outside described sealed pouch 10 is provided with the second explosive valve 23.
Further, in actual applications, when sealing of hole is carried out to the coal hole of rising borehole, this coal hole is placed in hole packer on being provided by the present embodiment, wherein, one end access automatic grouting machine of Grouting Pipe 20, the other end of Grouting Pipe 20 can retain certain length to grout outlet 22, insert together with the gas gas collection mouth 31 of gas drainage pipe 30 and above-mentionedly treat in the coal hole of sealing of hole, then start to start automatic grouting machine, slurries are from automatic grouting machine to Grouting Pipe 20 slip casting, when pressure in Grouting Pipe 20 acquires a certain degree, the first explosive valve 21 that Grouting Pipe 20 is provided with can pop, slurries can flow in sealed pouch 10, after pouch 10 to be sealed fills slurry, slurries can continue to flow into Grouting Pipe 20, when pressure acquires a certain degree, the second explosive valve 23 which is provided with can pop, slurries flow out from the grout outlet 22 of Grouting Pipe 20, owing to this being placed in the coal hole of rising borehole to hole packer, meeting and horizontal plane have a certain degree, therefore slurries under gravity, downward deposition, thus can by good for the hypomere shutoff in above-mentioned coal hole, gap between the hole wall that shutoff rear slurry can equally fill gas drainage pipe 30 and from above-mentioned coal hole to water bottled water, thus realize slurries and seal boring, and retain extraction passage, avoid gas leak phenomenon of holing.
Further, the present embodiment device also comprises splicing tape 40, outside the sticky port of export being located at trepanning 11 of splicing tape 40, sealed pouch 10 and gas drainage pipe 30 is adhesively fixed, with fixing seal pouch better.
