The "half" of the half-sheath body in the invention does not mean that the two half-sheath bodies are joined together and must be the whole arc-shaped closed body or nearly the circular half. The sealing air bag can also be of a flat cushion type.
The two opposite sides of the half sleeve body are respectively provided with an arc-shaped expansion convex edge 21a and a corresponding arc-shaped expansion groove 21b in cooperation with the wall surface of the connecting part. When the pipeline is relatively large, the distance between the two half sleeve bodies is relatively large, and the arc-shaped expansion convex edge 21a and the arc-shaped expansion groove 21b can be used for realizing the rush repair of the pipeline with the size changed in a certain range, so that the space between the two half sleeve bodies can be kept approximately the same when in use. So as to improve the sealing strength and reliability of the sealing airbag to larger pipelines.
One half of the sleeve body 1b and the corresponding sealing air bag are provided with mutually corresponding drainage holes 4, and the drainage holes of the sealing air bag and the sealing air bag form air-tight isolation.
