Title (EN) METHOD FOR LINING OF LATERAL PIPELINES WITH FLOW-THROUGH APPARATUS
(FR) TECHNIQUE DE CHEMISAGE DE PIPE-LINES LATERAUX PAR UN SYSTEME A CIRCULATION DIRECTE
Abstract: front page image
(EN)An apparatus for the installation of an inverted resin impregnated flexible tubular liner in a lateral passageway (53) from a main passageway (52) while permitting the flow of fluids through the main passageway (52) during the installation process is provided. A cylindrical body (12) with an opening (16) to coincide with and interact with the lateral passageway (53) has an expandable bladder (33) on its outside with an opening coincident with the body opening (16) and an elbow portion (27) on the inside which is firmly attached at the opening (16). An air supply inflates the bladder (33). A tubular elbow (27) is attached to a flexible hose (43) at its proximal end, the hose (43) having a gland for injecting fluid into the hose for inverting and curing the liner.
(FR)Appareil d'installation d'une chemise tubulaire flexible retournée imprégnée de résine dans un passage latéral (53) à partir d'un passage principal (52), qui permet l'écoulement de liquide par le passage principal (52) pendant le processus d'installation. Un corps cylindrique (12) percé d'une ouverture (16) coïncidant et communiquant avec le passage latéral (53) est muni d'une vessie dilatable (33), du côté extérieur, avec un orifice coïncidant avec l'ouverture (16) du corps cylindrique et une partie coudée (27), du côté intérieur, fixée fermement sur l'ouverture (16). Une arrivée d'air gonfle la vessie (33). Un coude tubulaire (27) est rattaché à un tuyau souple (43) à son extrémité proximale. Le tuyau (43) est muni d'un presse-étoupe permettant d'injecter du liquide dans le tuyau pour retourner et nettoyer la chemise.
