限定されず、任意構造物に適用できる。After the ring 20 is expanded as described above, the pipe 13 is then inserted into the duct 12. In this case, as shown in FIG. 3, the tip of the pipe 13 is pressed against the inner surface of the tongue piece 126. By bringing the tongue piece portion 126 into contact with the tip end portion of the pipe 13 in this way, it is possible to prevent the sewage in the underground box 10 from leaking to the outside of the underground box 1 as indicated by the broken line arrow N. Next, the band 14 is extended to the extension 12
Tighten to 2. The work for connecting the pipe 13 to the underground box 10 is completed as described above. In addition, for example, a paste such as a water-stop bond may be applied to an appropriate place such as the outer peripheral surface of the thick portion 121. Although the pipe of the above embodiment is a sewer pipe, the present invention can be applied to a pipe such as a cable pipe for laying a cable line. Further, the piping object is not limited to the underground box and can be applied to any structure.
