Description

Plugging bag

Technical Field

The invention relates to the technical field of mine plugging, in particular to a plugging bag.

Background

At present, many mines need to be subjected to hydraulic fracturing in advance to achieve the effect of releasing rock burst, but are influenced by complex geological structures, a proper blocking method for a high-pressure water injection hole or a gas drainage hole is not found, the existing method is to block a pipe body by using a polyurethane foaming bag after the pipe body descends or ascends to a specified position, and in the process of filling and solidifying the bag body, as a large shearing force exists between the sealing body and the hole, the bag body can slide in the hole in a loose manner under the condition of insufficient shearing force resistance, so that the blocking effect cannot be achieved, and a novel blocking bag needs to be designed.

Disclosure of Invention

In order to effectively solve the problems in the background art, the invention provides a plugging capsular bag, which has the following specific technical scheme:

an occlusion bag comprises a bag which is bound on the outer layer of a tube body; one end of the bag is provided with a feed inlet; the outer surface of the bag is pasted with a solid glue layer, the outer layer of the solid glue layer is pasted with a smooth protective film, and the end part of the protective film is provided with a traction device.

Preferably, the bag is provided with a discharge port, and the discharge port and the feed port are arranged on the same side of the bag;

preferably, the traction device comprises a hook arranged at the bottom of the protective film, and the hook is connected with a traction rope;

preferably, the material of the bag is cloth, rubber or plastic film.

Preferably, the bag can be penetrated by the tube body and fixed by binding the upper end and the lower end of the bag.

Preferably, the pouch is bound to the tube body through upper and lower ends of the pouch to achieve fixation.

Preferably, the upper end and the lower end of the protective film are respectively clamped with the solid glue layer.

A method for using an occlusion capsular bag comprises the following steps;

connecting a feed inlet with an injection tube, binding a bag on a tube body in the forward direction, extending the tube body into the hole, pulling a traction rope when the tube body extends to a specified position, tearing off a protective film attached to a solid adhesive layer, and then injecting a solidifiable material into the bag until the bag is fully filled and expanded and is attached to the side wall of the hole through the solid adhesive layer;

preferably, the settable material is cement paste or polyurethane raw material;

the bag has the beneficial effects that the bag body can be bonded with the holes in the process of expanding and solidifying the filling material, so that certain shearing resistance force is formed between the bag body and the holes in the process of solidifying the material, and the sealing effect is enhanced.

Detailed Description

The technical scheme of the patent is further explained in detail by combining the specific embodiment;

an occlusion bag comprises a bag 1, wherein the bag 1 is bound on the outer layer of a tube body 7; one end of the bag 1 is provided with a feed inlet 2; the outer surface of the bag 1 is pasted with a solid glue layer, the outer layer of the solid glue layer is pasted with a smooth protective film 3, and the end part of the protective film 3 is provided with a traction device; the traction device comprises a hook 5 arranged at the bottom of the protective film, and the hook 5 is connected with a traction rope 6;

the discharge port 4 is arranged on the bag 1, and the discharge port 4 and the feed port 2 are arranged on the same side of the bag 1; the discharge port of the bag 1 of the device can be used for discharging air in the bag at the initial stage of installation, so that the bag can be fed more conveniently, the feed port and the discharge port are provided with plugs, and the discharge port can be plugged firstly and then filled with materials in the using process;

the material of the bag 1 is cloth or rubber or plastic film, the bag 1 can be penetrated through by the tube body 7 and fixed by binding the upper end and the lower end of the bag 1, the bag 1 is bound with the tube body 7 by the upper end and the lower end to realize fixation, the binding fixation of the bag is realized by binding the upper end and the lower end of the bag, the binding position does not influence the use of a feed inlet and a discharge outlet, and the binding mode can bind the bag by iron wires and the like;

the upper end and the lower end of the protective film 3 are respectively clamped with the solid glue layer; when the tube body of the bag moves in the hole, the protective film can be scratched due to external environment reasons, so that the protective film falls off in advance, the protective film is clamped by embedding two ends of the protective film into the solid adhesive layer, the hook of the traction rope is connected with the protective film clamped in the solid adhesive layer, and the protective film is separated from the solid adhesive layer by pulling the traction rope in the using process so as to realize tearing;

a method for using an occlusion capsular bag comprises the following steps;

connecting a feed inlet 2 with an injection tube, binding a bag 1 on a tube body 7 in the forward direction, extending the tube body 7 into the hole, pulling a traction rope 6 when extending to a specified position, tearing off a protective film 3 attached to a solid adhesive layer, then injecting a solidifiable material into the bag 1, wherein the solidifiable material is cement paste or polyurethane raw material, and after the bag 1 is fully injected and expanded, the expanded bag is tightly attached to the hole wall, so that the solid adhesive layer is attached to the side wall of the hole; at the in-process that the material solidifies, because the volume can reduce slightly, the dynamics that the lateral wall of bag and pore wall was pressed close to this moment reduces, and then can produce decurrent shearing force, and the bag can be fine with pasting of pore wall lateral wall this moment provides the shearing resistance force, strengthens sealed dynamics greatly.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the invention.
