[0036] Such as image 3 versus 4 As shown, a gas drainage borehole sealing device includes a solid drainage tube body 10 for inserting into a gas drainage borehole. The drainage tube body 10 is made of polycarbonate PC, and the drainage tube body 10 After being inserted into the borehole, the end at the depth of the borehole is called the deep end 11 and the end at the outer edge of the borehole is called the connecting end 12. The drainage pipe body 10 is provided with a grouting channel 13 that is not connected to each other. The extraction channel 14 and the repair material channel 15 pass through the two ends of the extraction tube body 10 and the two ends of the extraction channel 14 are open. The grouting channel 13 and the repair material channel 15 are at the connection end 12 of the extraction tube body 10 Both ends are open, the other ends of the grouting channel 13 and the repair material channel 15 are all closed, and the suction tube body 10 is sequentially fixed an...
