Description
Technical field
The utility model relates to gas tunnel driving technology, particularly a kind of hole sealing device for tunnel piercing gas pumping hole.
Background technology
When highway, railway tunnel driving are through coal seam, for guaranteeing to tunnel safety, need first to carry out pump drainage to the gas in coal seam, to prevent coal seam and Gas Outburst, guarantee that tunnel safety tunnels, and drainage holes sealing quality are the key determining gas pumping effect.Due to lower to the sealing of hole pressure requirements of gas exhaust in tunnel piercing, and pump drainage hole is set to lateral aperture or near-horizontal hole usually.Existing high for the sealing of hole section pressure-bearing after the hole sealing device sealing of hole of coal bed gas extraction, but complex structure, sealing of hole cost is high, is not suitable for tunnel piercing drainage holes sealing of hole.For this reason, a kind of hole sealing device of the gas-discharging hole be applicable in tunnel piercing is needed.
Summary of the invention
The purpose of this utility model is exactly for the deficiencies in the prior art, provides a kind of hole sealing device for tunnel piercing gas pumping hole, and this apparatus structure is simple, sealing of hole speed is fast, can effectively reduce tunnel piercing cost.
For realizing aforementioned object, the utility model adopts following technical scheme.
For the hole sealing device in tunnel piercing gas pumping hole, comprise Grouting Pipe, exhaust pipe and slurry recovering tube; Described Grouting Pipe, exhaust pipe and slurry recovering tube are all made of plastics, and Grouting Pipe and slurry recovering tube are all tied up by iron wire and be fixed on exhaust pipe, and the front end of Grouting Pipe forms grouting tube section; Described exhaust pipe is fixedly connected with pre-inflated air bag, and pre-inflated air bag is positioned at the grouting tube section front of Grouting Pipe and the pump drainage floral tube section rear of exhaust pipe.
Adopt this hole sealing device of preceding solution, during sealing of hole grouting, the floral tube section of pre-inflated air bag for stoping cement paste to flow to exhaust pipe.Because Grouting Pipe, exhaust pipe and slurry recovering tube are all made of plastics, and Grouting Pipe and slurry recovering tube are all tied up by iron wire and are fixed on exhaust pipe; Meanwhile, the mode by arranging pre-inflated air bag on exhaust pipe forms the front end barrier structure of sealing of hole cement paste.Effectively can simplify structure, save material consumption and reduce manufacturing cost and use cost in modes such as the metal material of the plastics of low value replacement high value.Meanwhile, utilize the shrinkage character of pre-inflated air bag, conveniently device can be placed in pump drainage boring, its sealing of hole is easy to operate.
Preferably, the first block plate of being fixedly connected with by exhaust pipe of described pre-inflated air bag and the second block plate grip.Effectively can guarantee that pre-inflated air bag is in exhaust pipe fixation, and improve hole sealing device placement further as the convenience in pump drainage hole.
Preferred further, described first block plate and the second block plate are located at pre-inflated air bag front and rear respectively, and the first block plate diameter is greater than the second block plate diameter, and the first block plate diameter is less than the latus rectum of gas-discharging hole.To improve sealing of hole operation convenience further, and large diameter first block plate is utilized to improve the effect of pre-inflated air bag prevention sealing of hole cement paste.
Preferably, the spout part of described Grouting Pipe and slurry recovering tube is provided with stop valve; The mouth of pipe of described exhaust pipe is provided with snap joint.To improve the convenience of sealing of hole operation further, after closing two stop valves, the cement paste in sealing of hole section can be made to flow out before consolidation, guarantee sealing of hole effect; Snap joint is used for sealing of hole and is connected fast with exhaust pipe with pump drainage facility, improves pump drainage efficiency.
The beneficial effects of the utility model are, structure is simple, sealing of hole speed is fast, sealing of hole is effective, effectively can reduce tunnel piercing cost, improve drivage efficiency.
