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 pipe 1A is provided at an end 10 with a cylindrical insert end 3 formed by adhering a synthetic resin layer 5 to the outer surface of the end 10 so as to fill at least corrugated recesses 2a. A second corrugated synthetic resin pipe 1B is provided at an end 11 with a socket 4 formed by adhering synthetic resin to the outer surface of the end 11 and cylindrically extending the resin outwardly in the axial direction.
