Title (EN) PIPE CONNECTING METHOD
(FR) PROCEDE DE CONNEXION DE TUYAUX
Abstract: front page image
(EN)A method for sealing the gap between a sewer liner (3) and a connecting conduit (2) to the sewer, such as a drain, includes providing a hole in the liner for communication with the conduit, sealing a flexible bag (7) to the liner about said hole, and applying pressure to the bag to force at least a portion of the bag into the conduit so as to bridge the gap between the liner and the sewer at the point of connection of the conduit. Preferably a suitable grouting material is then introduced into the gap so as to surround the bag where it bridges the gap, thereby making a permanent seal between the liner and the connecting conduit.
(FR)Un procede permettant d'assurer l'etancheite de l'espace entre un tuyau d'egout (3) et une conduite de connexion (2) a l'egout, telle qu'un drain, consiste a amenager un trou dans le tuyau en communication avec la conduite, a sceller un sac flexible (7) sur le tuyau autour de ce trou, et a appliquer une pression sur le sac pour forcer au moins une partie du sac d'entrer dans la conduite de maniere a enjamber l'espace entre le tuyau et l'egout au point de connexion de la conduite. De preference, un materiau approprie de jointoiement au mortier liquide est ensuite introduit dans l'espace de maniere a entourer le sac lorsqu'il enjambe l'espace, creant ainsi un joint permanent entre le tuyau et la conduite de connexion.
