Description
100%L’aménagement hydroélectrique de la centrale Saint-Gabriel n’est plus en service depuis 1961. Pour des raisons de sécurité, plusieurs structures ont fait l’objet d’un démantèlement au fil des années, telles que le déversoir, la centrale ainsi qu’une partie du mur de la prise d’eau. Certaines installations ont toutefois été laissées en place, dont les conduites forcées entre la prise d’eau et la centrale. Depuis plusieurs années, une problématique d’affaissement des sols est identifiée sur le terrain.

Le phénomène a été étudié et il a été convenu que les détériorations sont attribuées à l’érosion interne des matériaux granulaires de remblai à l’endroit de la zone située entre le mur guideau et la conduite forcée de droite. Certaines réparations ont été réalisées pour corriger la situation, mais les affaissements continuent d’évoluer. Les enjeux de sécurité ont mené à la fermeture du site au public en 2021. La Ville de Shannon, propriétaire du site, souhaite entreprendre les travaux nécessaires afin d’éliminer la problématique d’affaissement. Les interventions visent à garantir la sécurité des lieux et à rétablir l’accès au public, en vue de sa mise en valeur. La solution retenue pour éradiquer le phénomène d’affaissement consiste à retirer une section de la conduite forcée de droite, à excaver les sols de remblai hétérogènes entre le mur guideau et la conduite forcée gauche et à mettre en place un tapis drainant offrant un comportement adéquat face aux écoulements internes présents sur le site.
