Connection structure of wave-shaped synthetic resin pipes, wave-shaped synthetic resin pipes used for the connection structure, and manufacturing method thereof

Abstract

Provided are a connection structure for connecting corrugated synthetic resin pipes and a corrugated synthetic resin pipe used in the connection structure. The pipe is lightweight, low cost, and simply structured with a small number of components, having sufficient resistance to water and pressure, and excellent sealing performance without the use of robust material or requiring high precision, and capable of being easily connected and manufactured. A first corrugated synthetic resin pipeA is provided at an endwith a cylindrical insert endformed by adhering a synthetic resin layerto the outer surface of the endso as to fill at least corrugated recesses. A second corrugated synthetic resin pipeB is provided at an endwith a socketformed by adhering synthetic resin to the outer surface of the endand cylindrically extending the resin outwardly in the axial direction.
