Background
In some coal mines, the hole sealing failure of the underground waterproof casing is caused by the hole cutting, so that the accident of flooding a working face is often caused, the currently commonly adopted underground waterproof casing is a casing with a 1.4-meter long screw-thread gate and a crude rubber sleeve, and through a plurality of experiments, the casing is only suitable for the distance between the left layer and the right layer of 3MP being 10 meters to 30 meters, and the leakage can be caused when the pressure exceeds 30 meters. Therefore, in some panel areas of coal mines, the interlayer distance is 40-50 meters in the process of releasing accumulated water on a plurality of working surfaces, water leakage often occurs under the water pressure of about 5mp, and the plugging effect is poor. There is a need to improve existing lost circulation devices.
Disclosure of Invention
The utility model provides an improved underground waterproof sleeve plugging device, aiming at solving the problem that the existing waterproof plugging sleeve is easy to leak water when exceeding a certain pressure and often causes flooding of a working surface.
The utility model is realized by the following technical scheme: the utility model provides a waterproof cover plugging device in pit, includes the traction tube, the traction tube is hollow, the head of traction tube is connected with the jackscrew through strengthening the nut, the pipe shaft portion cover of traction tube is equipped with and removes tray and gum cover, afterbody and is equipped with the tray, the gum cover is located the tray and removes between the tray, the both ends of gum cover wrap up respectively in the outside of removing tray and tray, the external diameter of gum cover and tray, the external diameter of removing the tray is the same.
The utility model is small to the drain hole space of the deep well of underground construction, and the situation is complicated and changeable, the waterproof sleeve length can not be too long, so designed this kind of waterproof set plugging device in pit, mainly include the traction tube, gum cover and jackscrew, the traction tube is hollow, the head of the traction tube is connected with jackscrew through the reinforcement nut, the jackscrew can be fixedly connected with anchor bolt or other fixed elements of the panel area, make it can lean against the traction tube through the connection of the reinforcement nut, make the traction tube stop up the well hole of leaking, the tube body of the traction tube is fitted with and moved tray and gum cover, the foot section is fitted with the tray, gum cover and moving the tray can all be dismantled, the gum cover is located between tray and moving the tray, move the tray and can drive the gum cover to move, can also dismantle the tray at the same time, in order to embolia the gum cover; in order to fix, the two ends of the rubber sleeve are respectively wrapped on the outer sides of the movable tray and the outer side of the movable tray, and the outer diameter of the rubber sleeve is the same as that of the tray and the outer diameter of the movable tray, so that the rubber sleeve expanded and pulled after being pressed and expanded can play a good role in leaking stoppage. The utility model has the following specific operations: firstly, data and information such as stroke sealing state locking conditions are obtained through test pressure, a rubber sleeve is adjusted, a movable tray can be moved, the whole rubber sleeve structure is moved, after the structure is arranged and fixed, the tray at the tail of a traction pipe is downwards inserted into a well mouth, the well wall is sealed through the rubber sleeve, after the traction pipe is inserted and sealed, a reinforcing nut at the head of the traction pipe is connected with a jackscrew, and the jackscrew is connected with a fixed component in a disc area or a roadway to press the head of the traction pipe; after a period of operation, the traction tube can be removed to drain accumulated water in the traction tube.
Preferably, the rubber sleeve is formed by arranging the raw rubber sleeve and the cooked rubber sleeve at intervals, so that the rubber sleeve is prevented from being damaged under pressure, and the rubber sleeve has a better effect than the traditional sleeve through tests.
Preferably, an amorphous sealing ointment is smeared between the rubber sleeve and the traction tube, the amorphous sealing ointment is a poly sealing ointment, and the material, a metal material and a rubber piece have good cohesiveness and higher tensile and tear strength, can be tightly adhered to the well wall under the action of pressure and has a good leaking stoppage effect.
Compared with the prior art, the utility model has the following beneficial effects: the underground waterproof sleeve leakage plugging device provided by the utility model has the advantages of good leakage plugging effect, high tensile and tearing strength, increased safety strength, improved safety coefficient of underground drilling, safety guarantee for the underground drilling work, good safety benefit and wide popularization and application.
