Conception et d\u00e9veloppement d\u2019un nouveau syst\u00e8me d\u2019\u00e9limination et de gestion des boues\u00a0: LODOGEST<\/h2>\n

Dur\u00e9e du projet:\u00a0Du 01\/08\/2014 au 31\/12\/2015\u00a0<\/em>

Le but de ce projet consiste \u00e0 concevoir et \u00e0 d\u00e9velopper un nouveau syst\u00e8me qui \u00e9vite l\u2019accumulation du sable, du limon et de l\u2019argile dans les r\u00e9serves d\u2019eau (artificielles ou naturelles), principalement dans celles construites par l\u2019homme, comme des r\u00e9servoirs ou des retenues d\u2019eau destin\u00e9es \u00e0 de l\u2019irrigation, \u00e0 l\u2019accumulation d\u2019eau sanitaire ou dans la plupart des cas pour la production d\u2019\u00e9lectricit\u00e9 dans des centrales hydrauliques. Le probl\u00e8me \u00e0 r\u00e9soudre est le colmatage. Les s\u00e9diments provoquent un alluvionnement du barrage, les s\u00e9diments atteignent un niveau d\u2019environ deux m\u00e8tres qui progresse vers l\u2019embouchure de la centrale, en la colmatant quand ils l\u2019atteignent.<\/p>\n

Le syst\u00e8me est complexe, tout le poids de la solution propos\u00e9e ne peut pas s\u2019appuyer sur la base de la retenue, car il s\u2019agit de retenues imperm\u00e9abilis\u00e9es par le biais de membranes plastiques et g\u00e9otextiles. Cela provoquerait des efforts et des d\u00e9compensations dans la chape entra\u00eenant des ruptures et fuites. La solution propos\u00e9e est fond\u00e9e sur une action m\u00e9canique avec des \u00e9l\u00e9ments r\u00e9sistants \u00e0 l\u2019abrasion, et sur une action hydraulique d\u2019appui qui aide \u00e0 briser le front des boues et \u00e0 r\u00e9duire le pourcentage de s\u00e9diments en suspension.<\/p>\n
