Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] A rapid air-inflation grouting sealing method, comprising the following steps:

[0023] (1) Fix the airbag sealer in the drill hole, the airbag sealer includes polyethylene pipe 1, airbag I2, airbag II3, air intake pipe I4, air intake pipe II5, grouting pipe 6; the airbag I2 and airbag II3 is respectively fixed on both ends of the polyethylene pipe 1 through clamps; the air intake pipe I4 is fixed on the horse-toothed copper mouth of the airbag I2, and the air-intake pipe II5 is fixed between the two airbags with a horse-toothed copper On the mouth, the grouting pipe is fixed between the two air bags through the φ16 hole opened on the air bag I2;

[0024] (2) Inflate the two airbags through the inflation end of the air intake pipe I of the airbag sealer;

[0025] (3) After the grouting material is stirred evenly in the mixing tank, the pneumatic grouting pump ...

Abstract

The invention discloses a rapid inflation grouting hole-sealing method and belongs to the hole sealing technology for underground gas extraction. The rapid inflation grouting hole-sealing method comprises the steps of fixing an air bag hole-sealing device in a drill hole, wherein the air bag hole-sealing device comprises a polyethylene pipe, an air bag I, an air bag II, an air feed pipe I, an air feed pipe II and a grouting pipe, the air bag I and the air bag II are fixed at two ends of the polyethylene pipe respectively through hoops, the air feed pipe I is fixed on an external thread copper nozzle of the air bag I, the air feed pipe II is fixed on an external thread copper nozzle between two air bags, and the grouting pipe penetrates through a phi16 hole on the air bag I to be fixed between the two air bags; the inflation end of the air feed pipe I inflates the two air bags; and grouting materials are pumped between the two air bags and drill hole inner walls from the grouting pipe through a pneumatic grouting pump after being evenly stirred in a stirring barrel. By means of the rapid inflation grouting hole-sealing method, the hole sealing speed is improved, the safety of connected hole sealing operation is improved, the cost is low, hole sealing media can be taken everywhere, and the wide practicability of the hole sealing technology is improved.

Description

technical field [0001] The invention belongs to a hole sealing process in underground gas drainage, and in particular relates to a fast air-inflation grouting hole sealing method. Background technique [0002] In the mine gas drainage work, the gas drainage pipe is connected to the gas drainage borehole, and the sealing medium is used to seal the hole sealing pipe and the inner wall of the borehole tightly, and the process of preventing air from being sucked into the borehole is collectively called hole sealing. . [0003] The currently used sealing media are generally yellow mud, polyurethane, and cement. The use of these three media for hole sealing has the disadvantages of high cost, complicated hole sealing process, slow hole sealing speed, and potential safety hazards. Contents of the invention [0004] The invention aims to solve the problems of high cost, complex process, slow speed and potential safety hazards in the existing hole sealing technology, and provides...
