CORRUGATED SPIRAL PIPE FITTED WITH JOINT, ITS MANUFACTURE AND METHOD FOR CONNECTING AND SEALING CORRUGATED SPIRAL PIPE

摘要

PURPOSE: To surely and easily secure a watertight state by interposing a bandlike sealer between the inner circumferential surface of a sheathing part and the outer circumferential surface in at least two rounds of the crest part of a pipe end and filling the space of a trough part surrounded by the sealer by a foaming resin agent. ;CONSTITUTION: A bandlike sealer B having a T-shaped cross section is wound at one round or more in both ends of the crest part (c) in one side of the pipe end (a) of a corrugated spiral pipe A while pinching so one trough part (d) that a T-shaped upper even part is positioned in the crest part (c) of the pipe d Thereafter a cylindrical joint main body 1 covering the wound part is so sheathed by the other half 1B that about a half 1A in the longitudinal direction thereof is projected to the outside and remains. Furthermore a liquid foaming resin agent C is poured into the crest part (d) from the pouring port 4 formed in the sheath part 1B and foamed. The space of the crest part (d) surrounded by the sealer B is filled by the foaming resin agent C. Thereby a joint is rapidly and surely fitted to the pipe end of the spiral pipe in a watertight state.;COPYRIGHT: (C)1994,JPO&Japio
