<P>PROBLEM TO BE SOLVED: To provide a spirally corrugated synthetic resin pipe with a joint, and a connecting structure of the spirally corrugated synthetic resin pipe having sufficient water resistance and pressure resistance and excellent sealing property without needing a firm material or high accuracy with a simple structure with a small number of parts, to attain weight and cost reduction while simplifying handling and connection work in the field. <P>SOLUTION: The spirally corrugated synthetic resin pipe with the joint has a socket part 4 for connecting the spirally corrugated synthetic resin pipes to each other at the piping end. The socket part 4 extending in cylindrical shape in a pipe axis direction from the end of the spirally corrugated synthetic resin pipe, is formed of foamable resin, and at least the outer peripheral surface of the connection side end in the formed socket part is formed with an FRP layer 8a with reinforcing fiber impregnated with resin. <P>COPYRIGHT: (C)2011,JPO&INPIT |
