Description of the Related Art Conventionally, when cracks or holes are opened in a conduit or a small sewage pipe buried in the ground and water leaks, a defective portion is digged from the surface of the ground to find a defective portion. Was repaired or replaced. However, recently, a technology has been developed to insert a small TV camera into the duct from the manhole to find a defective part from the inside, and this technology has made it possible to find the defective part and inspect the defective state. Repair technology from inside the pipeline has also been developed. As an example, as shown in FIG. 1, a cylindrical body (wheel tube) 10 having both ends closed and a cylindrical sliding member 11 provided on the circumference of both ends is inserted into the pipeline 1. As shown in FIG. 2, a rubber tube 20 is loosely fitted on the outer periphery of the cylindrical body 10 over its entire length, and both ends of the rubber tube are tightened and fixed to the cylindrical body 10 by tightening tools 16 as shown in FIG. It is. A repair material 21 impregnated with a curable resin binder is loosely wound around the outside of the rubber tube 20. This device is inserted up to the defective portion of the pipeline 1, and air of a required pressure is supplied by the air hose 13 to expand the rubber tube 20 so as to contact the inner surface of the pipeline 1 and pressurize the inner surface. The repairing material 21 is pressed between the rubber tube 20 and the inner surface of the pipe line 1 to be in close contact therewith. The expanded state of the rubber tube 20 at this time is, as shown in FIG. 1, from (a) to (b) and (c) to (d), which is a sufficiently expanded state. The repair material is hardened by leaving it for a certain period of time in a state where is pressed, and the repair material is brought into a state of being exactly attached to the inner surface of the pipeline. After complete curing, the air is released from the cylindrical body 10 and the device is taken out of the manhole to complete the repair. This method is generally called EPR (Engineering Plastic
Pipe Repair) is called the construction method.

せたものであることができる。The inventor of the present invention has conducted intensive studies to solve the above-mentioned problems. As a result, in the above-mentioned expansion and compression bonding method, the center of a repair material made of various fibers impregnated with a resin binder (adhesive resin) was used. By making a cross cut in the part with a cutter or the like, the repair material can be crimped to the mounting joint of the mounting pipe, and it has been found that water and breakage from the connection part can be easily repaired,
The present invention has been reached. That is, the present invention
(1) A rubber tube is loosely fitted to the outside of a cylindrical body, and a repair device in which a repair material made of various fibers impregnated with a resin binder is wound around the rubber tube is inserted into a pipe defect portion, and the rubber tube is removed. In the method of repairing pipeline defects from the inner surface by expanding the repair material on the outer periphery by inflating with air, pressing it against the inner surface of the pipeline, and curing it, make a cut in the center of the repair material impregnated with resin binder The repaired material is wound around a cylindrical body, and it is positioned at the mounting joint of the mounting pipe to be repaired. Pressurized air is injected to press the repair material against the inner surface of the pipe, and the mounting joint and mounting of the mounting pipe are performed. A method for repairing a joint portion of an attached pipe in a pipe line, which comprises extruding a cut portion of the repair material into a pipe, pressing and curing, and (2) a cut portion at a central portion of the repair material is 2 or more. (1) The repair method described in (1), in which the cutting lines are crossed, and (3) The repair material is cut, but a small hole is formed by cutting off the center of the cut end. (4) The repair method according to (1), wherein the repair material comprises a cut material or a cut hole formed by cutting off a central portion of the cut front end, or a combination thereof. It is about. The pipeline repair method of the present invention will be described in more detail. As shown in FIGS. 2 and 4, the repair material 21 is loosely wound around the rubber tube 20. The repair material 21 is a reinforcing material such as glass fiber, other carbon fiber, and Kepler fiber, and a resin binder that is an engineered plastic resin such as an unsaturated polyester resin, an epoxy resin, and an emulsion resin. This is a synthetic resin product that is made into a mat shape by impregnating a binder and has a constant strength in the directionality. Various repair materials can be combined according to the size and strength of the target defect. One or more repair materials are used one on top of the other, and the number is adjusted according to the size of the defect. For example, three ordinary glass cloths and a cotton-like glass cloth (waterproof mat)
One in which two sheets are alternately stacked is used as one set. At this time, as shown in FIG. 5, (1) a set of repair materials was cut in a cross shape, but the center of the cut end was slightly cut off and a small square hole was drilled. 2) Another set of repair materials is cut in a cross shape, but the center of the cut end is slightly cut off to make a small square hole, shifted from the first set, for example, the first set It is rotated 45 degrees with the thing and superimposed and wound. As a result, the tip of the repair material crimped into the mounting joint becomes linear, and the finish of the repair becomes clean. The length of the above-mentioned cross-shaped cut is appropriately determined according to the diameter of the mounting pipe, but it is usually preferable that the length is substantially the same as the diameter of the pipe. In addition, the notch in the center of the repair material may be any that can repair the repair material at the joint of the fitting pipe, and any one that cuts by crossing two or more lines outside the cross It goes without saying that it can be used,
Each of the cuts may be formed by cutting a central portion of a cut end of the cut and having a small hole formed therein, or a mixture of a mixture thereof.

One end of this tow rope is attached to the tow ring 15 of the front end portion 12 of the cylindrical body, and the air hose 13 is connected to the air hose connection pipe at the rear end. If it cannot be used, attach a push-in base to the air hose connection pipe and push the device into the defective area before use. In this case, if necessary, the repair material 21 may be protectively covered with an extremely thin rubber tube. In this way, as shown in FIG. 3 or FIG. 4, the pressurized air inlet 1 which is pulled or pushed into the mounting joint of the defective mounting pipe and attached to the inner surface of the pipe by the air hose 13 into the cylindrical body device.
When the rubber pipe 20 contacts the inner surface of the pipe 1 and is inflated so as to pressurize the inner face by supplying air at a required pressure from the pipe 4, the repair material 21 wrapped around the outer side becomes the rubber pipe 20 and the pipe 1. Pressed against the inner surface of At this time, the cross cut portion of the repair material located just below the mounting joint of the mounting pipe enters into the mounting pipe, rises, and is crimped to the bonding section. When the rubber tube 20 swells, as shown in FIG. 4, since the rubber tube 20 swells sequentially from the center, the water between the rubber tube 20 and the inner surface of the pipe 1 is simultaneously pushed out to the outside, and is in an anhydrous state. As a result, the rubber pipe 20 comes into direct contact with the pipe 1 and the inner surface of the mounting pipe, and thus the repair material 21 comes into direct contact with the pipe 1 and the inner surface of the mounting pipe. At this time, in the pressurized rubber tube, the thickness of the rubber tube below the cross cut portion of the repair material is appropriately reduced, thereby making it easy to bulge. Further, a convex rubber tube (see FIG. 6) fitted to the mounting tube can be used as the pressurized rubber tube. In this case, the repair material is wound in such a manner that the cross-shaped cut is pressed in accordance with the convex portion. By using this convex pressurized rubber tube, the repair material can be more easily pressed against the joint of the mounting pipe.

Is left for a certain period of time in a state where is pressed, the underwater curable resin such as an unsaturated polyester resin is cured.
The curing time varies depending on the climate and temperature, but is about 1 hour in summer and 2 to 2.5 hours in winter. At this time, heating is not particularly necessary, but heating can be performed to shorten the curing time. After complete curing, the air in the cylinder 10 is released, the rubber tube 20 is shrunk to the position of the cylinder 10 as before, and the device is taken out of the manhole by pulling the tow rope or air hose. Complete.
In this case, when the device is pulled into the pipeline 1, the sliding material 11
If the outside diameter of the pipe is used in accordance with the inside diameter of the pipe 1, the inside of the pipe can be cleaned when the apparatus is pulled in, and the adhesive strength of the repair material 21 can be improved. .
In addition, by making the winding width of the repair material 21 smaller than the width of the rubber tube 20, the end of the repair material after the repair becomes thin and rounded, and catching occurs when an electric wire or the like is inserted. Nothing.
