<p>PROBLEM TO BE SOLVED: To connect a foaming resin pipe to a pipe joint without generating the intrusion of water into a foaming layer by scraping a tip of the foaming resin pipe till a synthetic resin pipe is exposed, and forming the inner diameter of a stopper, which is formed in a back side of the inside of a receiver port of a pipe joint, so as to coincide with the outer diameter of the exposed synthetic resin pipe. SOLUTION: In the case of connecting a foaming resin pipe 10 having a foaming layer 12 and a pipe joint 30, a pipe end 16 and a tip 15 of the foaming resin pipe 10 and a receiver port 31 and a stopper part 32 of the pipe joint 30 are coated with the adhesive agent 1. At this stage, an outer layer 14 and the forming layer 12 of the foaming resin pipe 10 are scraped so as to expose a synthetic resin pipe 13. The outer surface of the tip 15 is pressure-connected to the inner surface of the stopper 32. At this stage, even in the case where a pipe end surface 11 of the foaming resin pipe 10 is obliquely cut, since the synthetic resin pipe 13 and the inner surface of the stopper 32 are pressure-connected to each other, exposure of the foaming layer 12 inside of a pipeline is prevented. Intrusion of the water into the foaming layer 12 is thereby securely prevented by pressure-connecting the tip 15 to the inner surface of the stopper 32.</p> |
