    Le site pilote de la Bass\u00e9e est un grand projet destin\u00e9 \u00e0 r\u00e9duire les effets d’une inondation majeure en Ile-de-France tout en respectant et en valorisant l’\u00e9cosyst\u00e8me. Il consiste en un espace endigu\u00e9 d’environ 8km qui permet de stocker ponctuellement, au moment du pic de crue, un volume d’eau de 10 millions de m3 sur une surface totale de 360ha. La digue a une hauteur maximale de 3m50 et est accessible aux pi\u00e9tons et aux cyclistes. Le trac\u00e9 a \u00e9t\u00e9 \u00e9tudi\u00e9 et optimis\u00e9 pour r\u00e9duire au maximum l’impact sur le foncier, l’environnement et les remont\u00e9es de nappe souterraine. Les travaux consistent en la r\u00e9alisation de la digue p\u00e9riph\u00e9rique, la cr\u00e9ation d’une station de pompage et diverses actions de restauration \u00e9cologique des zones humides et d’anciennes gravi\u00e8res \u00e0 l’int\u00e9rieur de l’espace endigu\u00e9. La conception de la digue p\u00e9riph\u00e9rique a \u00e9t\u00e9 particuli\u00e8rement optimis\u00e9e en termes de hauteur pour limiter les couts et pr\u00e9server l’\u00e9quilibre environnemental et paysager du site. Pour la prot\u00e9ger de l’effet du clapot \u00e0 l’int\u00e9rieur du site li\u00e9 aux vagues g\u00e9n\u00e9r\u00e9es par le vent dans la retenue, une solution en gabions matelas a \u00e9t\u00e9 retenue. Par ailleurs un d\u00e9versoir en gradins de gabions de 155ml a \u00e9t\u00e9 pr\u00e9vu pour \u00e9cr\u00eater le trop plein lors du remplissage complet de la r\u00e9serve. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    L’entreprise T\u00e9r\u00e9lian a fait appel \u00e0 Maccaferri pour la fourniture des 40,000m\u00b2 de matelas Reno en raison de la fiabilit\u00e9 et la qualit\u00e9 des structures, de l’accompagnement technique mais \u00e9galement de la capacit\u00e9 de production au regard de telles quantit\u00e9s. Par ailleurs, Maccaferri a assur\u00e9 la pr\u00e9paration des structures avant leur remplissage in situ par les \u00e9quipes T\u00e9r\u00e9lian. Le d\u00e9versoir en gradins de gabions (1,200m3) a \u00e9t\u00e9 \u00e9tudi\u00e9, fourni et mis en \u0153uvre par les \u00e9quipes sp\u00e9cialis\u00e9es de Maccaferri, titulaires de la certification ROG ASQUAL.<\/p>\n

    Les matelas Reno et gabions sont \u00e0 base de grillage \u00e0 maille hexagonales double torsion dont les fils sont rev\u00eatus de GalMac (alliage Zn95\/Al5%) et d’une gaine polym\u00e8re PoliMac assurant une dur\u00e9e de service de 120 ans \u00e0 l’ouvrage et inerte pour l’environnement.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
