In conduits constructed of concrete pipes such as those mentioned above, it is necessary to prevent water from flowing through the conduit or leaking to the outside, but it is particularly important to prevent water from leaking into the treatment equipment at the end of the conduit, due to the processing capacity of the treatment equipment at the end of the conduit. It is necessary to prevent water from entering the pipe from the outside of the closed area.

<Operation> A heat-shrinkable sealing material is wrapped around the joint of the concrete constituting the pipeline, and if necessary, an elastic body such as rubber is interposed between the sealing material and the concrete 1 to the pipe to avoid openings. ,
Next, the sealing material is heated to shrink and tightened around the outer circumference of the concrete pipe, completely sealing the joint.

Figure 1 shows a case where the concrete pipe 1 is a straight pipe, and at the joint part that butts against the end face of the concrete pipe 1. An elastic body 2 is wound around the elastic body 2, and a heat-shrinkable sealing material 3 is further wound around the outer periphery of the elastic body 2.

1. It is convenient and necessary for the elastic body 2 and the sealing material 3 to be formed into a ring shape in advance to match the outer diameter of the pipe 1, but it is also possible to use, for example, a wide band-like material wrapped in layers. It is preferable that the sealing material 3 is wider than the elastic body 2 so that both sides of the sealing material 3 are directly wrapped around the concrete pipe 1.1, and a heat-shrinkable synthetic resin can be used as the material.
