Abstract
The utility model discloses a drilling and hole sealing device. According to the device, a third polyvinyl chloride (PVC) pipe (1) is connected with a second PVC pipe (10) through a second joint (5); the second PVC pipe (10) is connected with a first PVC pipe (11) through a first joint (4); a rubber pipe (3) is communicated with the tail end of the third PVC pipe (1); the front end of the first PVC pipe (11) is connected with a conical plug (6); and the drilling and hole sealing device is characterized in that a first group of Malisan (7) and a second group of Malisan (8) are respectively bound at parts which are respectively 0.5m away from the first joint (4) on the left and right; a third group of Malisan (2) is bound at the second joint (5); and a fourth group of Malisan (9) is loosely bound at the part of at the tail end of the third PVC pipe (1), which is 1.5m away from the orifice. The drilling and hole sealing device is simple in structure, convenient to use, low in price and convenient to operate, the problem that the coal oxidation is accelerated due to low hole sealing quality is solved, and the problems that the high gas cannot be normally drained due to drilling gas leakage and the like are solved.
Description
Technical field
This drilling and sealing device relates to mine gas and administers technical field, relates in particular to the sealing of hole effect of firedamp taking-out discharging drilling.
Background technology
In the coal in China production field, the drilling and sealing quality has great function at aspects such as gas drainage under suction, coal body water filling, forward probe and gas controls, but sealing quality is poor in the middle of application process, hole-sealing technology is discontinuous, because oxidation easily produces CO, bring adverse effect for anti-fire-fighting work, gas control in holing in the drilling-draining process.
Summary of the invention
The technical problems to be solved in the utility model: provide a kind of simply, hole sealing device efficiently, poor to solve sealing quality, hole-sealing technology is discontinuous, because oxidation easily produces CO, brings adverse effect for anti-fire-fighting work, gas control in holing in the drilling-draining process.
The technical solution of the utility model:
A kind of device of drilling and sealing, comprise: the 3rd pvc pipe is connected by No. two joints with second pvc pipe, second pvc pipe connects by a joint in first pvc pipe, sebific duct is communicated with the 3rd pvc pipe end, first pvc pipe front end is connected with the taper plug, loose and the second group of Mary of first group of Mary is loose to be tied up respectively at each 0.5m place apart from joint left and right, the 3rd group of loose the tying up No. two joints of Mary, and the 4th group of Mary falls apart and ties up at 1.5m place, the 3rd pvc pipe end-to-end distance aperture.
The quality that each group Mary falls apart is 500 grams.
First pvc pipe and taper plug link are with holes.
A joint and No. two joints are snap joint.
The beneficial effects of the utility model:
This drilling and sealing device utilizes the Mary to distribute the principle of bubble, to hole inside and outside isolated, to reach the effect of sealing, reduce air to the oxidation of coal body and the effect of in time extraction of high gas, its simple in structure, easy to use, cheap, convenient operation, solved sealing quality poor, coal body is accelerated the problem of oxidation, having solved boring gas leakage and having caused the normally problem such as extraction of high gas.
Description of drawings:
This drilling and sealing of Fig. 1 apparatus structure schematic diagram;
This drilling and sealing of Fig. 2 device is completed the structural representation after sealing of hole.
The specific embodiment:
Embodiment: the 3rd pvc pipe 1 is connected by No. two joints 5 with second pvc pipe 10, second pvc pipe 10 connects by a joint 4 in first pvc pipe 11, sebific duct 3 is communicated with the 3rd pvc pipe 1 end, first pvc pipe 11 front end is connected with taper plug 6, the quality that each group Mary falls apart is 500 grams, the loose 7 and second groups of Marys loose 8 of first group of Mary tie up respectively at each 0.5m place apart from joint 4 left and right, the 3rd group of Mary loose 2 ties up No. two joint 5 places, the 4th group of loose the tying up at the 3rd pvc pipe 1 1.5m place, end-to-end distance aperture of Mary 9.Connect with the extraction main line with sebific duct at last, and tighten.Can carry out extraction to the high gas in holing, realize the purpose that coal-bed gas is administered, can solve again boring gas leakage and cause the coal body oxidation, cause the coal body spontaneous combustion.
