Abstract

Ils utilisent une conduite (10) en matière thermoplastique, par exemple en polychlorure de vinyle, qui est chauffée par un dispositif (11a) et aplatie et pliée par un dispositif (11) avant d'être bobinée en un rouleau (12). La conduite ainsi aplatie peut ensuite être déroulée, après avoir été chauffée, sous cette dimension réduite, à l'intérieur d'une conduite existante avant d'être de nouveau chauffée et expansée pour doubler la paroi intérieure de la conduite existante et, une fois durcie, résister aux pressions hydrostatiques et terestres extérieures. Domaine d'application : réfection de canalisations soutterraines, etc.
