Title (EN) METHOD AND APPARATUS FOR MAKING PLASTIC DRAINAGE PIPE REINFORCED BY STEEL STRIPS AND THE PLASTIC DRAINAGE PIPE REINFORCED BY STEEL
(FR) PROCÉDÉ ET APPAREIL PERMETTANT DE FABRIQUER UN TUYAU DE DRAINAGE EN PLASTIQUE RENFORCÉ PAR DES BANDES D’ACIER ET TUYAU DE DRAINAGE EN PLASTIQUE RENFORCÉ PAR DE L’ACIER
Abstract:
(EN) The present invention relates to a method for making a plastic drainage pipeline reinforced by steel strips, comprising the steps of (1) steel strips and plastic being integrated to form a composite profile having ribs reinforced by steel strips; (2) the composite profiles being transported to an installation site; (3) the composite profiles being wound, and simultaneously the edge of the profile being melted and welded to form plastic drainage pipes reinforced by steel strips; and (4) a spigot joint being made at one end of the pipe. The present invention also relates to a plastic drainage pipe made by the method, comprising a plastic pipe body and reinforcing ribs integrated with the plastic pipe body as a whole, wherein the ribs of the plastic pipe are reinforced by steel strips enwrapped by the plastic. The present invention also provides an apparatus for making the plastic drainage pipe reinforced by steel strips.
(FR) La présente invention concerne un procédé permettant de fabriquer une canalisation de drainage en plastique renforcée par des bandes d’acier. Le procédé consiste à : (1) intégrer des bandes d’acier et du plastique afin d’obtenir un profil composite doté de nervures renforcées par des bandes d’acier ; (2) transporter les profils composites sur un site d’installation ; (3) enrouler les profils composites, et simultanément faire fondre et souder le bord du profil afin d’obtenir des tuyaux de drainage en plastique renforcés par des bandes d’acier ; et (4) créer un joint d’emboîtement à une extrémité du tuyau. La présente invention porte également sur un tuyau de drainage en plastique obtenu à l’aide de ce procédé, qui comprend un corps de tuyau en plastique et des nervures de renforcement intégrées au corps de tuyau en plastique formant ainsi un ensemble, les nervures du tuyau en plastique étant renforcées par des bandes d’acier enveloppées dans le plastique. En outre, la présente invention a trait à un appareil permettant de fabriquer un tuyau de drainage en plastique renforcé par des bandes d’acier.
