Background technology
At present, in colliery field, often needing to drill to coal seam and gas accumulation region carries out coal mine gas drainage, with prevention
The generation of the security incidents such as gas explosion, Gas Outburst, when carrying out gas pumping, usually first to coal bed drilling, drilling is connect
Carry out extraction on dedicated line, drilling and the connection of pipe special, usually first insert connecting tube in hole, by cement mortar or
Person's polyurethane is filled up the gap of connecting tube and hole wall, then connecting tube and pipe special are attached, using polyurethane
During sealing of hole, polyurethane easily foam it is uneven, cause sealing it is not tight enough, leak air phenomenon, and sealing effect is bad, and gathers
Urethane cost is higher, not economical enough, and during the existing progress sealing of hole using cement mortar, after solidification, matter is rigid for cement mortar
It is crisp, when being pressed impact by ground, crack is often produced, makes drilling gas leakage, the effect of gas pumping is influenced, is needed after extraction
Drilling is blocked, when being blocked using existing device, with time integral, gas amount gradually increases in hole, and pressure becomes
Greatly, when closure cement mortar loosens, easily cement mortar is ejected together with device, triggers security incident, using effect
It is bad.
The content of the invention
In order to improve the above situation, a kind of coal mine gas drainage sampling pipe connection of the present invention provides one kind and passes through pressure
