Abstract

L'invention concerne un procédé et un dispositif de rénovation de tuyaux d'égoûts, permettant une jonction améliorée aux conduites domestiques. Conformément à l'invention, des tuyaux en matière thermoplastique sont introduits dans un tuyau d'égoûts. Les tuyaux en matière plastique sont ensuite chauffés dans la zone recouvrant la jonction. Cette zone est ensuite entré par déformation dans la connexion à la conduite domestique (3), à la manière d'un raccord, au moyen d'un corps de déformation télescopique (7). Ce dernier, durant ce mouvement, entraîne une pièce profilée de transition, de forme annulaire (10) et, lorsqu'il est retiré, dépose celle-ci à l'intérieur du raccord ainsi formé. Il est également possible d'insérer une pièce profilée de connexion (14) qui est étanche, d'une part, vis-à-vis de la pièce de transition (10) et, d'autre part, vis-à-vis du raccord à la conduite domestique (3), en vue d'apporter une amélioration supplémentaire à la jonction à une conduite de raccordement domestique.
