Abstract
The utility model discloses a drainage drilling hole sealing gas leakage testing device. The drainage drilling hole sealing gas leakage testing device comprises a testing device body and a hole sealing pipe. The testing device body comprises a pressure pipeline and a fast air pipe. A fast air pipe joint is arranged at the front end of the fast air pipe and connected with an air pipe in a construction site. A valve is arranged on the fast air pipe. A pressure gage is arranged on the pressure pipeline, and the pressure pipe is fixedly connected together with the hole sealing pipe through a rubber sleeve and a clip. A drainage hole drilling pipe is sleeved on the outer wall of the hole sealing pipe. Under the condition that a drainage drilling hole is sealed, the pressure pipeline is firstly connected with the hole sealing pipe of the drainage drilling hole through the rubber sleeve and then fixed through the clip, the pressure pipeline is matched with positive pressure so that an air-tight test is conducted, after compressed air is supplied, if the value of the pressure gauge returns zero in a short time, the fact that gas leakage exists in the drilling hole sealing is determined, and a secondary grouting sealing hole process needs to be conducted; and if the value of the pressure gage remains stable in the short time, the fact that the quality of the drainage drilling hole sealing meets specifications is determined.
Description
Technical field:
The utility model relates to a kind of air tightness test device, particularly relates to a kind of extraction drilling and sealing gas leakage testing arrangement, belongs to the checkout gear that the colliery draws out methane and holes.
Background technology:
Sealing of hole is draw out methane a important technology in the boring of colliery, because hole sealing depth is generally at boring 5-13 rice, difficulty or ease find out the boring of gas leakage generally speaking.The negative pressure that draws out methane of the bad direct influence of sealing performance of boring makes simultaneously in the annulus of hole sealing tube and drill hole wall and also produces gas leak phenomenon, has reduced the extraction concentration of gas, has reduced the pumping volume of gas.Sealing under the situation in hole, how to judge whether extraction boring still exists gas leak phenomenon, this is present coal mining industry research staff's research direction.
The utility model content:
Technical problem to be solved in the utility model is: in order to detect the tightness of mine gas drainage drilling and sealing, avoid initial sealing of hole to leak air, the utility model provides a kind of extraction drilling and sealing gas leakage testing arrangement, satisfies the draw out methane demand of drilling and sealing work of colliery.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of extraction drilling and sealing gas leakage testing arrangement, comprise testing arrangement body and hole sealing tube, described testing arrangement body comprises pressure pipeline and quick airduct, described pressure pipeline and quick airduct are fixed and welded together, be provided with quick blast connection at quick airduct front end, fast airduct is provided with valve, and pressure pipeline is provided with pressure meter, and described pressure pipeline is fixed together by rubber sleeve and clamp and hole sealing tube.
Be set with the extraction drill pipe on the described hole sealing tube outer wall.
Described quick blast connection is connected with the airduct of job location.
Positive beneficial effect of the present utility model is as follows:
1, under the situation of sealing extraction boring, be connected pressure pipeline of the present utility model on the hole sealing tube of extraction boring by rubber sleeve earlier, after the clamp fixation, cooperate malleation to carry out air tight test, after covering pressure wind, observe manometric numerical value, if pressure meter numerical value makes zero at short notice, determine that there is gas leak phenomenon in this drilling and sealing quality, must carry out the secondary grouting sealing of hole; If pressure meter numerical value keeps stable at short notice after covering pressure wind, determine that this extraction drilling and sealing quality is up to specification.
2, the utility model is according to the sealing of hole situation of extraction boring, utilize malleation to carry out extraction boring air tight test, sealing quality to extraction boring is spot-check and is supervised, get rid of artificial sealing of hole gas leakage problem, improve the extraction concentration of gas, improved the pumping volume of gas, can study analysis and summary to the tightness of weak seam, collect perfect extraction pressure parameter, better service is in the production in colliery.
3, the utility model is simple in structure, easy to operate, can guarantee the sealing quality of extraction boring, effectively saves cost, reaches the extraction effect of expectation.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described explanation:
Referring to Fig. 1, a kind of extraction drilling and sealing gas leakage testing arrangement, comprise testing arrangement body and hole sealing tube 6, described testing arrangement body comprises pressure pipeline 8 and quick airduct 9, pressure pipeline 8 and quick airduct 9 are fixed and welded together, be provided with quick blast connection 1 at quick airduct 9 front ends, blast connection 1 is connected with the airduct of job location fast; Airduct 9 is provided with valve 2 fast, and pressure pipeline 8 is provided with pressure meter 3, and described pressure pipeline 8 is fixed together with hole sealing tube 6 by rubber sleeve 4 and clamp 7; Be set with extraction drill pipe 5 at hole sealing tube 6 outer walls.
Under the situation of sealing extraction boring, be connected pressure pipeline 8 of the present utility model on the hole sealing tube 6 of extraction boring by rubber sleeve 4 earlier, after clamp 7 fixations, cooperate malleation to carry out air tight test, after covering pressure wind, observe the numerical value of pressure meter 3, if the numerical value of pressure meter 3 makes zero at short notice, there is gas leak phenomenon in the quality of determining this drilling and sealing, must carry out the secondary grouting sealing of hole; If cover and press that the numerical value of pressure meter 3 keeps stable at short notice behind the wind, determine that the quality of this extraction drilling and sealing is up to specification.
