Abstract
The utility model discloses a double-wall corrugated pipe set with a novel assembling structure. The minimum widths of wave crests are all larger than the maximum widths of wave troughs, so that the ring rigidity of a first double-wall corrugated pipe and the ring rigidity of a second double-wall corrugated pipe are high. Besides, the longitudinal cross section of the outer wall of a connection plug is of a sawtooth shape, and an electric melting ring is embedded in the inner wall of a bayonet socket. When the double-wall corrugated pipes are assembled, the connection plug is inserted in an inner cavity of the bayonet socket, then the electric melting ring is electrified to melt the inner wall of the bayonet socket, melt glue is fully filled into a concave region on the outer wall of the connection plug, then the electrification is stopped to conduct cooling, the connection plug and the bayonet socket are bonded together, so that the double-wall corrugated pipe set is convenient to connect and reliable.
