Abstract
The utility model discloses a horizontal hole reaches and delays angling hole hole sealing device in pit, including slip casting pipe, gas injection pipe, return pipe, notes air -bags, polyurethane reaction bag. Slip casting pipe, gas injection pipe, polyurethane reaction bag is fixed and is adopted on the pipe taking out, gas injection pipe link in proper order to the right side from a left side and have quick -operation joint, the suction valve door, annotate air -bags, the return pipe fixed in the polyurethane reaction bag inflation back position with the contact of top drill hole wall, and the left side is provided with, and the location is protruding, the right side is provided with return pipe entry up. Utilize this device can make the hole sealing thick liquid be full of the space that is difficult to to fill after horizontal hole and the slow angling hole slip casting in drilling, improve the hole sealing effect, increase gas drainage concentration, convenient to use.
Description
Technical field
The utility model relates to a kind of hole sealing device, is particularly useful for down-hole horizontal hole and the gentle dip hole hole sealing device of underground coal mine sealing of hole.
Background technology
In the sealing of hole process of current underground coal mine inorganic material, discontented borehole space is often noted in actual slip casting, and especially lateral aperture eases up angling hole, can occur space near slip casting section medium position, have a strong impact on drilling and sealing effect, cause gas extraction concentration low.But, do not have good method head it off now.
Utility model content
The purpose of this utility model is the space that the difficulty formed in slip casting process for lateral aperture and gentle dip hole fills, and provides that a kind of structure is simple, easy to operate, the good down-hole horizontal hole of result of use and gentle dip hole hole sealing device.
For achieving the above object: down-hole horizontal hole of the present utility model and gentle dip hole hole sealing device, comprise the air injection pipe be located in boring, gas injection pouch, polyurethane reaction pouch, drainage tube, Grouting Pipe, return pipe, described Grouting Pipe, air injection pipe, polyurethane reaction pouch are fixed on drainage tube; Polyurethane reaction pouch is two, is located at the both sides of drainage tube, and described air injection pipe is connected with snap joint, gas injection valve, gas injection pouch from left to right successively; Described gas injection pouch is fixed on the drainage tube bottom between two polyurethane reaction pouches, the position contacted with top drill hole wall after described return pipe is fixed on polyurethane reaction bladder expansion.
The inner of described return pipe is provided with opening up return pipe entrance, and outer end is provided with and ensures return pipe Way in positioning convex upward.
Beneficial effect: the hole sealing device that the utility model adopts Grouting Pipe, air injection pipe, return pipe, gas injection pouch, polyurethane reaction pouch to form, the problem that sealing of hole effect is low is caused in the space that the difficulty formed in slip casting process for lateral aperture and gentle dip hole fills, during use, Grouting Pipe, air injection pipe, polyurethane reaction pouch, return pipe are fixed on relevant position, extruding polyurethane reaction pouch makes wherein A, B material fully mixing, send into the drilling and sealing degree of depth afterwards, after reacting completely, start slip casting; After grouting amount reaches the precalculated amount that can fill holing, stop slip casting; Open gas injection valve, utilize pressure air pump to the gas injection of gas injection pouch, when observing the uniform and stable pulp of return pipe, close gas injection valve and stop gas injection.By being discharged by the air in space thus making slurries be full of boring, improve sealing of hole effect, increase gas extraction concentration.
