Abstract
The utility model discloses a grouting capsule-type hole packer with multiple section seals. The grouting capsule-type hole packer with the multiple seal sections comprises a grouting pipe and also comprises at least two cloth bags. The grouting pipe penetrates all cloth bags in sequence; an interval is set between every two cloth bags; the tail end of the grouting pipe is closed; one-way check valves are respectively arranged at parts on all sections of the grouting pipe, which are respectively located in the cloth bags; and an explosion valve is arranged on the grouting pipe located between the two cloth bags. The grouting capsule-type hole packer with the multiple seals is simple in operation, good in hole packing effect, is high in applicability and high in efficiency and is safe and reliable.
Description
Technical field
The utility model relates to a kind of hole sealing device, especially relates to a kind of slip casting bag formula hole packer with multistage sealing.
Background technology
Coal and Gas Outburst are the Nature disasters that threatens Safety of Coal Mine Production, particularly in recent years along with the increase of the pit mining degree of depth, coal-bed gas pressure, gas bearing capacity increase gradually, in order to guarantee mine safety production, mine is adopted, is dug work plane and generally adopts the pre-gas pumping new technology of boring, thereby has brought shutoff and sealing problem between extraction hole and extraction pipeline.
At present, the way that addresses this problem has following several:
1, cement mortar shutoff: the cement mortar shutoff in use in hard, hard coal seam, sealing of hole speed is fast, sealing of hole is reliable, effect is fine, but relatively poor to the plugging effect of soft seam.
2, adopt the gas drainage under suction plugging device, gas drainage under suction plugging device expensive, complicated operation, plugging effect is unstable, has caused very large burden to the user, has affected the implementation of the pre-gas pumping new technology of mine, thereby threatens the safety in production in colliery.
3, adopt the hard polyurethane foam sealing of hole, shortcoming is complicated operation, and polyurethane foam passing in time produces shrinks, and has a strong impact on the sealing of hole effect.
4, adopt water (gas) pressure type hole packer, its shortcoming is that weight is heavier, inconvenient operation.
5, tapered capsule-type hole packer, its weak point are to the size in aperture and the bad adaptability of borehole shape, and sealing quality is difficult for guaranteeing.
The utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, a kind of slip casting bag formula hole packer with multistage sealing is provided, formed by a plurality of cloth bags, form multistage explosion infiltration seal area during work, have advantages of simple to operate, sealing of hole is effective, safe and reliable, applicability is strong, efficient is high.
The utility model is the deficiency that solves the problems of the technologies described above, and the technical scheme that adopts is:
A kind of slip casting bag formula hole packer with multistage sealing, comprise Grouting Pipe, also be provided with at least two cloth bags, described Grouting Pipe penetrates each cloth bag successively, be provided with an intersegmental distance between every two cloth bags, the Grouting Pipe endcapped is positioned at each section of Grouting Pipe on the part of cloth bag and is provided with inlet non return check valve, is provided with explosive valve on the Grouting Pipe between two cloth bags.
In the utility model, described cloth bag is reeled and is formed a trepanning.
In the utility model, described Grouting Pipe can penetrate last cloth bag and not pass.
In the utility model, described Grouting Pipe can penetrate last cloth bag and pass a segment distance.
The beneficial effects of the utility model are: the utlity model has advantage simple to operate, that sealing of hole is effective, safe and reliable, applicability is strong, efficient is high.
