バッグは管の構造物から取り出される。The object of the present invention is to provide a coiled repair sleeve having fixing parts at the edges and covered with an elastic gasket material, the coiled repair sleeve being inserted into the sleeve and being expanded by an airbag, for example. This is accomplished by using a repair sleeve. The sleeve with the airbag inserted is moved to the location of the damage or leak, and upon reaching the location,
An air bag or other expansion means uncoils the sleeve and inflates or expands to compress the gasket material against the inner wall of the tube. Thereafter, when the airbag is deflated, the sleeve will contract to some extent due to its spring-type nature and the resiliency of the gasket material. When this contraction occurs, the male fixation part of the sleeve slides into the groove of the male fixation part, and
Forms a continuous sleeve inside the tube. After deflation, the airbag is removed from the tube structure.

ーブすなわち管状のライナーを形成する。As shown in FIG. 3A, the male engaging portion 24 whose outer surface is exposed from the gasket 22 corresponds to the female engaging portion whose outer surface is covered by the compressible gasket 22. As another example, the male engaging portion 24 may be covered with a gas scaler 122. The thickness of the gasket 22 is substantially the same over the entire outer surface of the sleeve 14, except that if the outer surface of the male engagement portion is covered by the gasket, the thickness of the gasket at the male engagement portion may be The thickness is preferably thinner than the thickness of the rest of the outer surface of the sleeve 14 and is designed to ensure watertightness, typically using low density polyethylene foam or foam rubber. To effect the engagement or mutual fixation of the male engagement part 24 and the female engagement part 26, a wider groove than required is used, in which case the male engagement part 24 is covered with a gasket. As shown, the female engaging portion 26 preferably has an outer lip having a length substantially corresponding to the exposed portion of the male engaging portion having an outer surface covered with a gasket. and a shorter inner or lower lip 28 . As a result of pressurization by an air bag or other inflation means, the sleeve 14 expands into a larger configuration. That is, the male engaging portion 24 passes over the edge of the lower lip 28 and slides on the inner surface of the lower lip. Thereafter, when the airbag is deflated, the sleeve 14 tends to return to its smaller shape due to its spring characteristics, so that the male engagement portion 24 of the sleeve 14 engages the female engagement portion of the sleeve, as shown in FIG. 3B. It fits into a groove formed between the inner and outer lips of the portion 26. When the contraction ends,
After the airbag is removed from the sleeve, the male and female engaging portions 24 and 26 of the sleeve are fully secured together and a continuous sleeve or tubular portion is formed inside the tube 10, as shown in FIG. 3C. Form a liner.

ける。In the example shown in Figure 4, the edge of the female engagement part has a series of holes 25 and the male engagement part has a series of projections 27 in the form of hooks or studs. This example is particularly preferred if the two edges of the sleeve are to be fastened together. The protrusion and hole anchoring assembly locks the edges of the sleeve to hold the sleeve in a circular configuration once the elongated male engagement portion fits within the groove of the female engagement portion or the expansion force is released. When interconnected, it can be used as in the example described here. Therefore, when the airbag is inflated, the sleeve takes on a larger shape, and the male engaging portion 24 becomes the female engaging portion 26.
and then a series of projections on the hook or stud 2
7 slides into a series of holes. When the bag is retracted, the protrusion 27 hooks into the hole and remains firmly engaged in the anchoring position.
