Abstract

Cette invention se rapporte à un système de canalisation à confinement secondaire, qui comporte deux chambres d'accès espacées (20), lesquelles sont reliées entre elles par un tuyau de confinement secondaire (24), afin d'assurer l'étanchéité d'un tuyau d'amenée de fluides flexible, dont les extrémités sont disposées à l'intérieur des chambres d'accès. Le tuyau flexible externe (42) est conçu avec des dimensions qui permettent d'introduire le tuyau flexible primaire (40) et/ou de retirer ce tuyau flexible primaire, pendant les opérations qui visent à installer et à tester ledit tuyau flexible primaire et après l'opération de remblayage de la fouille dans laquelle est déposé ledit tuyau, le tuyau flexible externe étant conçu de façon à s'affaisser partiellement pour venir en contact avec le tuyau flexible primaire et pour empêcher tout mouvement relatif entre les deux tuyaux, tout en assurant un passage d'écoulement entre eux.
