Abstract

The utility model relates to a coal mine underground gas extraction hole-sealing device, in particular to a secondary high-pressure grouting hole packer. The secondary high-pressure grouting hole packer solves the problem that the sealing effect of the existing coal mine underground gas extraction hole-sealing technology is poor. The secondary high-pressure grouting hole packer comprises a double-resistant polyethylene drainage pipe, and two air bags are arranged on the double-resistant polyethylene drainage pipe; a communicating pipe arranged outside the double-resistant polyethylene drainage pipe is connected between two air bags; an air bag grouting pipe arranged outside the double-resistant polyethylene drainage pipe is also connected at the other side of one air bag, and a coal bed grouting pipe arranged outside the double-resistant polyethylene drainage pipe is also arranged on the air bag connected with the air bag grouting pipe in a penetrating manner. The coal mine underground gas extraction hole-sealing device is tight in plugging, has high gas extraction concentration, and can be widely suitable for all coal mine underground gas extraction sealing holes.

Description

The secondary high-pressure slip-casting hole packer
Technical field
The utility model relates to coal mine gas extraction hole sealing device, specifically is a kind of secondary high-pressure slip-casting hole packer.
Background technology
At present, coal mine gas extraction work has become the important process that highly gassy mine and coal and gas outburst mine must carry out.In gas pumping work, commonly used to the mash gas pumping drilling hole sealing technology, hole sealing technology is to carry out gas pumping after through certain equipment borehole sealing being accomplished fluently in the down-hole.The secondary high-pressure slip-casting hole packer is a kind of novel hole sealing technology that carries out the gas borehole sealing under the coal mine, carries out extraction after making gas in the coal body by the shutoff of secondary high-pressure slip-casting hole packer, gets into the extraction pipeline system, reaches the purpose that draws out methane.At present, what domestic each colliery sealing of hole adopted mainly is polyurethane sealing of hole technology, and main technique is: smear to after adopting polyurethane A, two kinds of material of B to stir and fill in boring on the calico that is wrapped on the pipe rapidly, utilize the chemical reaction of its foaming that shutoff is carried out in boring.This hole sealing technology can be with borehole sealing; And extraction by the road is in main system, but there is following problem in this borehole sealing technology: polyurethane itself belongs to the macromolecule combustible material, exists poorly sealed close behind the sealing of hole; Gas pumping concentration is low, influences drawbacks such as extraction concentration.
Summary of the invention
The utility model provides a kind of secondary high-pressure slip-casting hole packer in order to solve the existing bad problem of coal mine gas extraction borehole hole sealing technology sealing effectiveness.
The utility model is to adopt following technical scheme to realize: the secondary high-pressure slip-casting hole packer, comprise two anti-polyvinyl releasing pipes, and on two anti-polyvinyl releasing pipes two capsule bags are housed; Be connected with between two capsule bags and be positioned at two outer communicating pipes of anti-polyvinyl releasing pipe; The opposite side of one of them capsule bag also is connected with and is positioned at the outer capsule bag Grouting Pipe of two anti-polyvinyl releasing pipes; Be connected with also to be installed with on the capsule bag of capsule bag Grouting Pipe and be positioned at the outer coal seam Grouting Pipe of two anti-polyvinyl releasing pipes.During use, at first the described secondary high-pressure slip-casting hole packer of the utility model is embedded in an end that makes capsule bag Grouting Pipe and coal seam Grouting Pipe in the boring and leaks outside boring; Then the grouting pump high-voltage tube is connected with an end of capsule bag Grouting Pipe and carries out slip casting, thereby slurry in the entering of capsule bag Grouting Pipe and capsule bag that capsule bag Grouting Pipe is connected, two capsule bags is propped up in then through another capsule bag of communicating pipe entering and the inwall of holing compresses; Treat that pressure reaches; After the injecting cement paste rapid hardening; Thereby the grouting pump high-voltage tube linked to each other with an end of coal seam Grouting Pipe slurry is full of between two capsule bags of boring; Utilize slurry to drill hole wall slip casting shutoff drill hole wall and leakage path on every side thereof, from basic elimination boring gas leakage crack and form grouting pressure slurry is permeated to drill hole wall, finally solidify the realization sealing of hole through slurry.
Further, said two anti-polyvinyl releasing pipe is the two anti-polyvinyl releasing pipes of DN50; Said capsule bag is made up of the internal thread cloth in rubber sleeve, rubber sleeve cover and the outer external screw thread cloth cover of rubber sleeve, can make the capsule bag have bigger elasticity like this, very easily props up and the inwall of holing compresses, nor punctures easily.
The described device shutoff of the utility model is tight, and gas pumping concentration is high, has solved the bad problem of existing coal mine gas extraction borehole hole sealing technology sealing effectiveness, can be adaptable across all coal mine gas extraction sealing of holes.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the two anti-polyvinyl releasing pipes of 1-; 2-capsule bag; 3-capsule bag Grouting Pipe; 4-coal seam Grouting Pipe; 5-communicating pipe.
The specific embodiment
The secondary high-pressure slip-casting hole packer comprises two anti-polyvinyl releasing pipes 1, on two anti-polyvinyl releasing pipes 1 two capsule bags 2 is housed; Be connected with the communicating pipe 5 that is positioned at outside two anti-polyvinyl releasing pipes 1 between two capsule bags 2; The opposite side of one of them capsule bag 2 also is connected with the capsule bag Grouting Pipe 3 that is positioned at outside two anti-polyvinyl releasing pipes 1; Be connected with also to be installed with on the capsule bag 2 of capsule bag Grouting Pipe 3 and be positioned at the outer coal seam Grouting Pipe 4 of two anti-polyvinyl releasing pipes 1.Said two anti-polyvinyl releasing pipe 1 is the two anti-polyvinyl releasing pipes of DN50.Said capsule bag 2 is made up of cover of the internal thread cloth in rubber sleeve, the rubber sleeve and the outer external screw thread cloth cover of rubber sleeve.
