Abstract
(EN)
A method for lining, rehabilitating, repairing, and rejuvenating pipelines and passageways is disclosed. The method comprises the steps of hauling a tubular liner (10) into a section of pipeline (14) to be repaired, disposing a reforming member (34) within the liner at one end proximate one end of the pipeline, depositing a cement slug (16) in the host pipeline proximate the said one end, and expanding the liner within the pipeline against the inner surface of the said pipeline by urging the reforming member along within the liner under pressure. The outer surface of the liner is provided with a plurality of protrusions (12) in the form of grout anchor hooks which penetrate the cement along the length of the said liner thus ensuring a mechanical bond between said liner and said cement. The cement also adheres to the inner surface of the pipeline and thus a rigid, secure, water impermeable lining construction is achieved. The anchor hooks both prevent gravitational slump of the mortar, and also ensure that the liner does not fall from the cement. A substantially uniform thickness of cement is obtained, and the lining constructions adopts a substantially identical shape to that of the host pipe after the cement has hydrated.

L'invention a pour objet un procédé permettant de recouvrir, de remettre en état, de réparer et de rénover des canalisations et des caniveaux. Ce procédé comprend les étapes consistant à tirer un revêtement tubulaire (10) dans une section de la canalisation (14) à réparer, à placer un élément de rénovation (34) dans ledit revêtement au niveau d'une extrémité proche d'une extrémité de la canalisation, à déposer une gaine de ciment (16) dans la canalisation principale à proximité de cette extrémité, à assurer la dilatation du revêtement à l'intérieur de la canalisation contre la surface intérieure de cette dernière en poussant en forme l'élément de rénovation avec le revêtement sous pression. La surface extérieure du revêtement est pourvue de plusieurs éléments en saillie (12) sous forme de crochets d'ancrage en coulis de ciment qui pénètrent dans le ciment sur la longueur dudit revêtement et assurent ainsi une liaison mécanique entre ledit revêtement et ledit ciment. Ce ciment adhère également à la surface intérieure de la canalisation ce qui permet d'obtenir une construction de revêtement imperméable à l'eau, fixe et rigide. Les crochets d'ancrage évitent tout affaissement par gravitation du mortier et empêchent également le revêtement de se détacher du ciment. Il est ainsi possible d'obtenir une épaisseur de ciment sensiblement uniforme, et les constructions de canalisation présentent une forme sensiblement identique à celle de la canalisation principale après l'hydratation du ciment.
