Description
Technical field
The utility model relates to one and to discharge water drilling and sealing casing bit, particularly relates to controllable type that a kind of spy puts water in gob area and to discharge water drilling and sealing casing bit.
Background technology
At present, when water in gob area is put in coal mine test, usually run into goaf water and press through the series of problems brought greatly.Traditional way is, plays the boring that discharges water to protection coal seam, in the boring that discharges water, fill in sealing of hole sleeve pipe, and employing control gate valve discharges the ponding in goaf.But, if run into goaf hydraulic pressure comparatively large, can not the boring of shutoff in time water in gob area can be caused to pour in work plane, there is water leak accident, damage equipment, injury.After water in gob area flows to end, cause goaf air leaking, goaf pernicious gas is leaked enter airway or air flow in laneway enters goaf, cause goaf coal spontaneous combustion, bring great potential safety hazard to coal production.
In addition, if when having drilling rod in sealing of hole sleeve pipe, the target controlling gate valve just not only has fluid, and also having the drilling rod of solid, drilling rod itself takies the cross section of sealing of hole sleeve pipe in addition, is unfavorable for discharging water, the drilling rod in hole sealing tube can only being pulled out with water by force, then discharging water by controlling gate valve.But, if run into goaf hydraulic pressure larger time, be in severe operating environment when staff can be made to work, in-pipe flow splashes and makes that blurred vision is unclear, clothes drenches, and is unfavorable for the healthy of staff and personal safety.
Utility model content
The weak point that the utility model exists in order to avoid prior art, a kind of controllable type is provided to discharge water drilling and sealing casing bit, gush out to prevent water in gob area, guarantee drilling construction safety, prevent from goaf pernicious gas from leaking entering tunnel harm staff or air flow in laneway to enter goaf simultaneously and cause coal body spontaneous combustion.
The utility model technical solution problem adopts following technical scheme:
A kind of controllable type discharges water drilling and sealing casing bit, comprise sealing of hole sleeve pipe, retainer ring, dewatering outlet, pressure meter, control gate valve, wherein one end of sealing of hole sleeve pipe is wrapped with the some layers of sea-tangle and is fixed with wire rod, filling in constructs in advance is arranged in the boring that discharges water protecting coal seam, anchor pole is squeezed in the hole on retainer ring, sealing of hole sleeve pipe is fixed on protection coal seam, flange is utilized to be coupled together at the two ends of sealing of hole sleeve pipe, the gate valve that discharges water is installed in the outer end of sealing of hole sleeve pipe, it is characterized in that: one end that described sealing of hole sleeve pipe is wrapped with sea-tangle uses to be had certain flexible wire rod and bundle, dewatering outlet is provided with bottom the outer end of described sealing of hole sleeve pipe.
The utility model design feature is also
The outer end of described sealing of hole sleeve pipe is provided with pressure meter.
Hole diameter on described retainer ring and quantity match the diameter of anchor pole and quantity.
The beneficial effects of the utility model are: the utility model is by being wrapped with sea-tangle in one end of sealing of hole sleeve pipe and fixing with having certain flexible wire rod, solving very well discharges water between boring and sealing of hole sleeve pipe crams not tight problem, and ensures that sea-tangle has sufficient expansion space; By arranging dewatering outlet and pressure meter in the outer end of sealing of hole sleeve pipe, solve because of excessive the brought problem of hydraulic pressure, pressure meter can show hydraulic pressure, when needs rod pulling, because hydraulic pressure is excessive, should not use and control gate valve and directly to discharge water release, first can carry out abundant release by dewatering outlet, then open control gate valve, take out drilling rod; Cooperatively interacted by retainer ring and anchor pole, make sealing of hole sleeve pipe tightly be fixed on protection coal seam on; There is good stability, feature that reliability is high, efficiently solve because of excessive the brought problem of water in gob area pressure.
