Abstract
A pressure bearing type grouting hole packer with a pulp returning prevention device comprises a grouting pipe. At least two cloth bags are arranged on the grouting pipe, a certain distance exists between every two adjacent cloth bags, the grouting pipe sequentially penetrates through the cloth bags, the tail end of the grouting pipe is closed, a check valve is arranged on the portion, inside each cloth bag, of each section of the grouting pipe, an explosion valve is arranged on the portion, between every two adjacent cloth bags, of the grouting pipe, the explosion valves are sleeved with a sleeve, and the axial length of the sleeve is larger than or equal to the total axial length of the explosion valves. The explosion valves are sleeved with the sleeve, the sleeve is pressed against the outer portions of the explosion valves through pressing rings on the two sides of the sleeve, and therefore the pressure bearing type grouting hole packer with the pulp returning prevention device is simple in structure, capable of effectively solving the pulp returning problem produced after pulp injection is fully conducted, more convenient to operate, and capable of saving operation time.
Description
Technical field
The utility model relates to the hole sealing device that a kind of coal bed drilled tunnel is used, and especially relates to the belt pressing type fluid filling hole sealing device that a kind of band prevents anti-sizing device.
Background technology
In coal seam, Gas Outburst is the Nature disaster 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 the sealing problem between extraction hole and extraction pipeline.At present, the way that addresses this problem common employing is: at the coal bed drilled tunnel, by slip casting method, in conjunction with cloth bag, be encapsulated, this device comprises Grouting Pipe and at least two s' cloth bag, be provided with explosive valve on the Grouting Pipe between two cloth bags, yet the user finds to have following defect gradually in actual use, one, when a plurality of cloth bags are not filled with, middle explosive valve just is opened, and causes the usability of this hole packer poor; Two,, when filling with slurry, often there will be anti-slurry phenomenon, for preventing anti-slurry, the workman often says the union bending that grouting pump is connected with Grouting Pipe and shuts to prevent anti-slurry, therefore causes this device result of use poor, complex operation.
The utility model content
For solving the problems of the technologies described above, the belt pressing type fluid filling hole sealing device that the utility model provides a kind of band to prevent anti-sizing device, this device is by being provided with a sleeve pipe in the explosive valve outer cover, sleeve pipe is pressed in the outside of explosive valve by the both sides pressure ring, this is simple in structure, and efficiently solve the anti-slurry phenomenon of filling with after slurry, more convenient to operate, save the operating time.
The technical scheme that the utility model adopts is:
A kind of band prevents the belt pressing type fluid filling hole sealing device of anti-sizing device, comprise Grouting Pipe, at least be provided with two cloth bags on Grouting Pipe, be provided with an intersegmental distance between every two cloth bags, described Grouting Pipe penetrates each cloth bag successively, the Grouting Pipe endcapped, be positioned at each section of Grouting Pipe on the part of cloth bag and be provided with inlet non return check valve, be provided with explosive valve on the Grouting Pipe between two cloth bags, the outer cover of described explosive valve is provided with sleeve pipe, the axial length of the axial length >=explosive valve of sleeve pipe.
The utility model, between casing tube internal hole wall and explosive valve outer wall, two ends vertically are respectively equipped with pressure ring.
The beneficial effects of the utility model are: this device is by being provided with a sleeve pipe in the explosive valve outer cover, sleeve pipe is pressed in the outside of explosive valve by the both sides pressure ring, this is simple in structure, and efficiently solves the anti-slurry phenomenon of filling with after slurry, more convenient to operate, save the operating time.
The utility model is by be provided with a sleeve pipe in the explosive valve outer cover, the blasting time that its main role is the delay-action blasting valve, and can fully make slurry be full of a plurality of cloth bags, thereby effectively prevent from instead starching or overflowing, greatly improve the functional performance of this hole packer.
