Description
Technical field
The utility model relates to a kind of two pouch rapid hole sealing device, is mainly used in the rapid hole sealing of down-hole High Position Drilling.
Background technology
Goaf gas is gushed out and is made up of three parts, and country rock Gas, Residual coal in goaf are gushed out and Gas Emissions of Adjacent Layers.According to statistics, in the mine of the nearly half of China, Gas Outflow From Worked-out Area accounts for 35%～45% of face gas outburst amount, and minority mine is up to 80%～90%.Visible, goaf gas drainage is one of key of carrying out gas control on coal faces.Be exactly the boring to roof construction at air way for the High Position Drilling of goaf gas drainage, due to the impact of rock fracture around boring and rock motion, the sealing of hole effect of High Position Drilling is often poor, existing hole sealing device is a lot, it is mainly the hole sealing device of two pouch structures, its structure is two pouches, connect the Grouting Pipe of two pouches, be positioned at the one way valve of two pouches, explosive valve in the Grouting Pipe between two pouches, there are several problems in this structure: 1, pouch is in the time of slip casting, wherein a part of water can enter in two spaces between pouch, after causing shutoff, there is free G&W centre, the problems such as 2, explosive valve is opened grouting behind shaft or drift lining, and the empty G&W in its space cannot be discharged, and causes sealing effectiveness poor, and airtight quality is uncontrollable.
Utility model content
The utility model object is to overcome the above-mentioned shortcoming that prior art exists, and a kind of two pouch rapid hole sealing devices of good sealing effect are provided.
For achieving the above object, the technological means that the utility model adopts is: a kind of two pouch rapid hole sealing devices, comprise the first pouch, the second pouch, connect the Grouting Pipe of the first pouch and the second pouch, be arranged on two one way valves and an explosive valve in Grouting Pipe, two one way valves are arranged in the first pouch and the second pouch, and explosive valve is between the first pouch and the second pouch; It is characterized in that: also comprise that at least one is arranged on the drainage tracheae in the first pouch or the second pouch, be arranged on the upper pressure opening and closing valve between the first pouch and the second pouch of drainage tracheae; Described the first pouch and the second pouch are made up of the waterproof pouch sheet of a slice and the permeable pouch sheet of a slice, and the waterproof pouch sheet of the first pouch and the waterproof pouch sheet of the second pouch are oppositely arranged.
Further, described Grouting Pipe is arranged on one end of the first pouch and the second pouch, and drainage tracheae is arranged on the other end of the first pouch and the second pouch.
Further, in described the first pouch and the second pouch, drainage tracheae is all installed.
Further, described explosive valve is arranged in Grouting Pipe, is positioned at the first pouch and the second pouch centre position.
The beneficial effects of the utility model are: carry out borehole sealing by this structure, and sealing of hole fast and effectively, sealing of hole effect stability is controlled, and good sealing effect has been realized efficient fast sealing.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, Grouting Pipe, 2, the first pouch, 3, the second pouch, 4, one way valve, 5, explosive valve, 6, drainage tracheae, 7, pressure opening and closing valve, 8, waterproof pouch sheet, 9, permeable pouch sheet.
Detailed description of the invention
The two pouch rapid hole sealing devices of one as shown in Figure 1, comprise the first pouch 2, the second pouch 3, connect the Grouting Pipe 1 of the first pouch and the second pouch, be arranged on two one way valves 4 and an explosive valve 5 in Grouting Pipe, two one way valves 4 are arranged in the first pouch and the second pouch, and explosive valve 5 is between the first pouch and the second pouch; It is characterized in that: also comprise that at least one is arranged on the drainage tracheae 6 in the first pouch and the second pouch, be arranged on the pressure opening and closing valve 7 between the first pouch and the second pouch on drainage tracheae 6; Described the first pouch 2 and the second pouch 3 are made up of the waterproof pouch sheet 8 of a slice and the permeable pouch sheet 9 of a slice, and the waterproof pouch sheet of the first pouch and the waterproof pouch sheet of the second pouch are oppositely arranged.
Described Grouting Pipe 1 is arranged on one end of the first pouch 2 and the second pouch 3, and drainage tracheae 6 is arranged on the other end of the first pouch 2 or the second pouch 3.
In described the first pouch 2 and the second pouch 3, drainage tracheae 6 is all installed.
Described explosive valve 5 is arranged in Grouting Pipe 1, is positioned at the first pouch 2 and the second pouch 3 centre positions.
When use, grouting pump is thought grouting under pressure in Grouting Pipe, be positioned at the one-way valve opens slip casting of the first pouch and the second pouch, the water producing in slip casting process is appeared by permeable pouch sheet one side, and two waterproof pouch sheets of the first pouch and the second pouch are oppositely arranged, ensure that water can not enter in two spaces between pouch in pouch; After in pouch, slip casting finishes, explosive valve is opened the space slip casting between two pouches, there is air in the space between two pouches now, sometimes also has water in rock, because explosive valve is just to start slip casting after pressure reaches certain value, therefore, pressure between two pouches is opened the pressure opening and closing valve on drainage tracheae simultaneously, and water and air is discharged from two valves, in the time that injection slurry arrives pressure opening and closing valve, pressure opening and closing valve is closed, and slip casting finishes.This hole sealing device takes to discharge air, and more than each hole remains on 2MPa in the time that sealing of hole operates, has so just ensured that the sealing quality in each hole is identical, the method stable operation, advanced technology, leads over existing like product.The plugging effect of this hole sealing device is good, can in sealing of hole, not produce the not tight problem of shutoff, and shutoff efficiency is high.
The above; be only detailed description of the invention of the present utility model, be not limited to this, any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.
