When the apparatus is sent to a desired location in a drilling hole with the gas extraction pipe, the ropes are pulled to make the short pricking pins on the ring plate puncture the polyurethane black material bag and the polyurethane white material bag to outflow two liquids from the two bags for mixing; the ring plate is repeatedly pulled to repeatedly stir the fluids in the polyurethane black material bag and the polyurethane white material bag for full mixing; sealing materials formed by the mixed fluids expand continuously to burst the inner membrane and squeeze out of the plurality of holes on walls of the cylinder to be in close combination with walls of the drilling holes to seal the drilling holes.
Description
Technical field
The utility model relates to a kind of drilling and sealing device, belongs to coal mine lower area gas control technology and equipment field, especially relates to the coal mine down-hole drilling hole sealing technology.
Background technology
Gas accident is major casualty under the coal mine, and national control of coalmine gas policy confirms that highly gassy mine must be taken out afterwards earlier and adopt that gas pumping is the measure of effecting a permanent cure.China's coal-mine gas pumping rate is generally lower; Except the influence of geological conditionss such as gas permeability of coal seam difference, most important reason is that the sealing quality of boring is poor, effectively crack around the shutoff boring; It is fast to cause the colliery gas density decay in the extraction process, to occur, and gas flow is low.
China's coal-mine is generally used organic resin material or other macromolecular material at present, and these materials generally carry out hybrid reaction by two or more chemical grout and generate.Conventional method is to mix the number of chemical slurries through manual, utilizes cotton to adsorb after the stirring and is wrapped on the gas pumping pipeline, inserts the extraction hole in the lump with the gas pumping pipeline; Since from chemical grout from beginning to be mixed into the only tens seconds blanking time (usually less than 30s) of foaming; Thereby usually the gas pumping pipe in the extraction hole in the progradation mixed serum begun foaming and intumescing, stop further to advance, can't send to the sealing of hole position of setting; Do not reach the sealed borehole length of design; General 3 ~ the 4m of sealed borehole length, the sealing of hole section can not form effective seal in boring cranny development position.The several workmans of this arts demand are skilled in technique and close fit in addition, and workman's skin contacts chemical grout easily, and human body is had certain harm.
Summary of the invention
Technical problem: the purpose of the utility model is the weak point that overcomes in the prior art, and a kind of simple and compact for structure, mash gas pumping drilling hole sealing device that sealing of hole is effective is provided.
Technical scheme: the mash gas pumping drilling hole sealing device of the utility model; Comprise the cylinder that is furnished with some holes; Be attached with one deck inner membrance on the cylinder inner wall, the both sides of cylinder are respectively equipped with cylinder protecgulum and the cylinder bonnet that is sleeved on the gas pumping pipe, are provided with the Circular Plate that is furnished with a plurality of holes on the end face in the cylinder; Circular Plate one side is arranged with the spring that links to each other with the cylinder protecgulum; Be furnished with some prickers on the opposite side end face of Circular Plate, and be arranged with two stay cords that stretch out cylindrical outer, be provided with the black material of polyurethane capsule bag that is fixed on the gas pumping pipe and the polyurethane that is sleeved on the black material of the polyurethane capsule bag between Circular Plate and the cylinder bonnet and expect the capsule bag in vain.
The length of described cylinder is 0.2 ~ 0.5m, and diameter is 100mm.
Beneficial effect: owing to adopted technique scheme, utilize the cylinder that polyurethane black and white material capsule bag is housed, can realize the regulation and control of sealing of hole position; Can satisfy the requirement of design sealed borehole length, and a firm reaction compartment is arranged, through puncturing black and white material capsule bag; Make the slurries hybrid reaction in the black and white material capsule bag generate new encapsulant; Encapsulant constantly expands, and bursts the hole wall of extruding inner membrance and the some holes from the cylinder barrel and holing and combines closely, and realizes the sealing to boring.Have characteristics simple in structure, easy to operate, that controllability is strong, harmless.
