できる。As described above in detail, in the present invention, since the synthetic resin pipe is connected to the side wall of the manhole or the like using the flange joint made of an elastic material such as rubber, the connection angle of the synthetic resin pipe at the time of piping construction. The piping construction can be performed very easily by appropriately adjusting the temperature. Also, after the pipe is installed, external forces such as thrust loads and bending moments acting on the synthetic resin pipe can be absorbed by the rubber packing interposed between the sleeve and the synthetic resin pipe, so the plastic pipe is damaged at the connection. Can be reliably prevented.
