Rapid hole sealing device and method

Abstract

The invention discloses a rapid hole sealing device and method. The hole sealing device comprises a flow guide pipe, wherein at least two soft sealing plugs and at least one hole sealing agent tube located between the two adjacent soft sealing plugs are arranged on the outer wall of the flow guide pipe in a penetrating manner; each hole sealing agent tube is fixedly connected with the flow guide pipe, and a weak part allowing an expanding body to expand out is formed on each hole sealing agent tube; the soft sealing plugs are sealed and fixed in to-be-sealed drill holes through elastic deformation; the soft sealing plugs are movably mounted on the flow guide pipe in a movable sleeving manner through clearance fit, multiple first limiting elements are fixedly connected onto the flow guide pipe, one first limiting element is correspondingly arranged at the outer end of each soft sealing plug, and one first limiting element is correspondingly arranged at the inner end of at least one softsealing plug. The hole sealing method is implemented on the basis of the device. The rapid hole sealing device and method have the beneficial effects as follows: the hole sealing device is simple andreasonable in structure, the agent reaction is moderate, the combination is convenient, and the flow guide pipe of the hole sealing device can rotate and move back and forth in the hole for agent mixing; and the hole sealing method is convenient to operate, the hidden danger of leakage of hole sealing materials is avoided, and the hole sealing effect is good.

Description

Technical field [0001] The invention relates to a sealing technology in the technical field of coal seam gas drainage, in particular to a quick sealing device and a sealing method. Background technique [0002] In recent years, with the increase in coal production and the extension of mines to the depths, high gas and coal and gas outburst mines have increased, and the amount of coal seam gas outburst has been increasing. The problem of coal and gas outburst has become an issue affecting safety in major coal-producing countries in the world. The most important factor in production. Establishing a mine gas monitoring and monitoring system, improving a mine ventilation system, and establishing a mine outburst warning system are all powerful measures for mine gas control, but the most fundamental measure is still gas drainage. After drilling is completed, the key lies in the gas drainage system Maintenance and sealing of drainage holes. At present, there are many sealing methods a...

Problems solved by technology

[0003] The first purpose of the present invention is to provide a rapid hole sealing device for the defects that the existing double-medicine sealing device is difficult to control the insertion time and the gas cannot be discharged during the expansion process of the drug. The movable connection method of clearance fit, so that after the hole sealing device is placed in the hole, the two agents in the hole sealing drug cartridge can be fully mixed and reacted in the hole through forward and reverse rotation and forward and backward movement of the guide tube, and then expand. The agent cartridge is used to block the drilled hole to achieve the purpose of sealing the hole; and the air in the hole is discharged by using the gap between the sealing cork and the guide tube, so as to avoid the formation of pores in the expansion body, enhance the strength of the sealing section, and improve the sealing effect; the corresponding effective reduction It is difficult to mix the medicaments, so as to avoid the hidden dangers of premature insertion affecting the sealing quality, and too late insertion resulting in difficulty in insertion and bulging out of the medicament hole leading to the waste of medicaments, thereby improving the convenience of operation and ensuring the sealing quality
