The utility model discloses a kind of water filling hole sealing device, comprise high pressure water injection pipe, Grouting Pipe and swelling gasbag group, this swelling gasbag group comprises one and mates with high pressure water injection pipe the outer tube be set with, and is fixed with swelling gasbag respectively at the inside and outside two ends of outer tube; Run through in two swelling gasbags and be connected with tracheae, the outer end of tracheae is provided with tracheae valve; Described outer tube is provided with Grouting Pipe, and the end of this Grouting Pipe is between two swelling gasbags.The utility model is effectively swift to operate, and improve the sealing of high pressure water injection pipe, the support of outer tube can be that high pressure water injection pipe is drawn out easily.The utility model hydraulic coal wall water injection hole packer, structure is simple, and easily manufacture, result of use is very good, is beneficial to very much in field of mining promotion and implementation.
Description
Technical field
The utility model relates to the hole sealing technology in technical field of coal mine, is specifically related to one and carries out hole sealing device to the high pressure water injection pipe mouth of pipe.
Background technology
Along with the high speed development of coal industry and coal production mechanization, dust hazard problem in coal production is still severe, and the sick incidence of disease of coal worker's pneumoconiosis is higher, and coal-dust explosion happens occasionally, Gas Outburst is a kind of serious natural calamity of underground coal mine, the safety in production in serious restriction colliery.In coal mining manufacturing process, prevent the active and effective measure of the one of stope coal dust to rib or coal-bed flooding.Tradition short-cut method adopts cement mortar sealing of hole, inserts bottom the sealing of hole section of holing block then by cementing with timber wedge or cotton yarn by water injection pipe.Just can water filling after Behavior of Hardened Cement Paste slurry solidifies.To expend time in length with the water filling of cement mortar sealing of hole, waste be large, consume material is many, inconvenient operation, can not dynamical pressure water infusion be used for.On current domestic colliery, the main sealing of hole water filling device adopted has hydraulic expansion type hole packer.These water fillings and sealing of hole pressure are that the overflow valve by being located at expansion tube front end presets, after water injection hole packer inserts eyelet, even if the pressure preset does not meet eyelet specific requirement and can not adjust immediately yet, reset after water injection hole packer must being extracted out from eyelet, waste time and energy.
Utility model content
The purpose of this utility model is for prior art Problems existing and deficiency, provides a kind of water filling hole sealing device that effectively can prevent spray orifice.
For achieving the above object, adopt following technical scheme: a kind of water filling hole sealing device, comprise high pressure water injection pipe and Grouting Pipe, also comprise a swelling gasbag group, this swelling gasbag group comprises one and mates with high pressure water injection pipe the outer tube be set with, and is fixed with swelling gasbag respectively at the inside and outside two ends of outer tube; Run through in two swelling gasbags and be connected with tracheae, the outer end of tracheae is provided with tracheae valve; Described outer tube is provided with Grouting Pipe, and the end of this Grouting Pipe is between two swelling gasbags.Radial teeth is fixed with outside described swelling gasbag.Sealant is provided with between outer tube and high pressure water injection pipe.
The beneficial effects of the utility model: the utility model hydraulic coal wall water injection hole packer, first by air pressure, two swelling gasbags are propped up automatically and sealing formation one cast chamber is carried out to boring port, then utilize Grouting Pipe to carry out cast to cast chamber and form fixing seal chamber, effectively swift to operate, improve the sealing of high pressure water injection pipe, the support of outer tube can be that high pressure water injection pipe is drawn out easily.The utility model hydraulic coal wall water injection hole packer, structure is simple, and easily manufacture, result of use is very good, is beneficial to very much in field of mining promotion and implementation.
