Abstract
The utility model discloses a grouting hole packer, comprising a grouting bag and an extraction pipe; the grouting bag is used for sealing a gas extraction hole; the extraction pipe is used for extracting gas; the grouting bag consists of two locating plates and a bag body; through holes which are used for arranging the extraction pipe in a penetrating way are formed in the centers of the locating plates and the bag body; the two ends of the bag body are respectively connected with the locating plates, so that the formed grouting bag is provided with an inner sealing cavity used for grouting; a grouting pile and a mortar outlet pipe are also mounted on the locating plate at the outer side of the gas extraction hole; a pressure valve is arranged at the tail end of the mortar outlet pipe. The grouting hole packer is simple in structure, reasonable in design, low in cost and convenient to generalize and use; the locating plates are arranged, so that the grouting bag can be mounted at a proper position; the grouting bag is provided with the inner sealing cavity, cement mortar is filled in the inner sealing cavity for sealing, and the occurrence of the extraction pipe blocking condition is avoided; the bag body is made of an elastic material, grouting can be realized under the effect of high pressure, the grouting pressure requirement can be met, and the hole sealing effect is excellent.
Description
Technical field
The utility model relates to a kind of servicing unit for gas pumping, especially relates to a kind of fluid filling hole sealing device.
Background technology
Gas pumping is in mine operation, administers the important means of gas.In gas pumping process, need to guarantee the tight sealing of boring, to guarantee gas pumping effect.
In prior art, sealing boring in the following ways: the desired depth place in boring is provided with baffle plate, drainage tube, through this baffle plate, arranges inlet pipe at the place, aperture of boring.Use grouting pump that cement mortar is injected along inlet pipe, cement mortar can fill the hole between baffle plate, drainage tube and drill hole inner wall, continues slip casting until cement mortar is overflowed from outlet pipe, after cement mortar solidifies, realizes the sealing of boring.
When the pressure of injected water cement mortar is too large, at the bottom of cement mortar will enter hole along the crack-leakage of baffle plate and drill hole inner wall, stop up drainage tube, affect extracting result, if select little slip casing by pressure, can make sealing of hole pressure limited, sealing of hole effect is bad.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and a kind of fluid filling hole sealing device is provided, and adopts utricule slip casting to avoid occurring stopping up the appearance of drainage tube situation.
The utility model is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of fluid filling hole sealing device, comprise for sealing slip casting bag and the drainage tube for drawing out methane of gas extraction hole, described slip casting bag is comprised of two location-plates and utricule, the center of location-plate and utricule is provided with for wearing the through hole of drainage tube, the two ends of utricule are connected with location-plate respectively, the slip casting bag forming has the closed cavity for slip casting, is positioned on the location-plate in gas extraction hole outside Grouting Pipe and outlet pipe are also installed, and outlet pipe end is provided with pressure valve.
Described location-plate is made by hard material.
Described utricule is made by elastomeric material.
Described location-plate is disc.
The diameter of described location-plate is greater than the diameter of gas drainage under suction bore end.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, cost is low, is convenient to promote the use of, be provided with location-plate simultaneously and slip casting bag can be arranged on to correct position, slip casting bag has closed cavity, and cement mortar is injected closed cavity and sealed, and has avoided stopping up the appearance of drainage tube situation, the utricule that adopts elastomeric material to make, can slip casting under high pressure effect, grouting pressure is satisfied the demands, sealing of hole is respond well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.

Graphical indicia: 1, ore bed; 2, gas extraction hole; 3, drainage tube; 4, Grouting Pipe; 5, utricule; 6, location-plate; 7, outlet pipe; 8, pressure valve; 9, closed cavity; 10, through hole.
The specific embodiment
Shown in figure, the specific embodiment is as follows:
A kind of fluid filling hole sealing device, comprise for sealing slip casting bag and the drainage tube 3 for drawing out methane of gas extraction hole, described slip casting bag is comprised of two location-plates 6 and utricule 5, the center of location-plate 6 and utricule 5 is provided with for wearing the through hole 10 of drainage tube 3, the two ends of utricule 5 are connected with location-plate 6 respectively, the slip casting bag forming has the closed cavity 9 for slip casting, is positioned on the location-plate 6 in gas extraction hole outside Grouting Pipe 4 and outlet pipe 7 are also installed, and outlet pipe 7 ends are provided with pressure valve 8.
Described location-plate 6 is made by hard material.
Described utricule 5 is made by elastomeric material.
Described location-plate 6 is disc.
The diameter of described location-plate 6 is greater than the diameter of gas drainage under suction bore end.
The utility model in use, first get through gas extraction hole, then gas extraction hole is carried out to reaming processing, until the needed degree of depth, the utility model is installed into, location-plate 6 is just stuck in reaming hole afterwards and the intersection in original hole, then starts slip casting, when utricule internal pressure reaches setting value, pressure valve is opened and is stopped slip casting, static a period of time, slurry solidifies, and plays sealing function.
The technical scheme that the utility model is cited and embodiment are not restrictions, in the cited technical scheme of the utility model and embodiment is equal to or effect same approach is all protected at the utility model scope.
