    La capacit\u00e9 d\u2019accueil du quai Lamartine \u00e0 Arles n\u2019\u00e9tait pas suffisante pour permettre aux paquebots de 135m d\u2019accoster. Afin de permettre l\u2019accostage de ce type de bateaux, la CNR, ma\u00eetre d\u2019ouvrage, a mandat\u00e9 la construction d\u2019un nouvel appontement en rive gauche de Arles \u00e0 l\u2019amont du pont aux Lions et du quai Lamartine. <\/p>\n

    Pour cela, il \u00e9tait pr\u00e9vu la mise en place de 5 ducs d\u2019Albe, l\u2019installation de passerelles m\u00e9talliques dont les appuis sont fond\u00e9s sur micropieux et la protection de la berge par matelas gabions pr\u00e9remplis. Au pr\u00e9alable, le mur existant est renforc\u00e9 par la mise en place de tirants. L\u2019ensemble de ces travaux ont \u00e9t\u00e9 r\u00e9alis\u00e9s par voie fluviale depuis une barge install\u00e9e sur le Rh\u00f4ne.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    La CNR, ma\u00eetrise d\u2019\u0153uvre du projet, a retenu une solution par matelas gabions pr\u00e9remplis de 30cm d\u2019\u00e9paisseur, afin de prot\u00e9ger les berges et r\u00e9sister \u00e0 l\u2019\u00e9rosion g\u00e9n\u00e9r\u00e9e par les bateaux lors de man\u0153uvres d\u2019amarrage. Cette technique a \u00e9t\u00e9 retenue par rapport aux enrochements pour plusieurs raisons :<\/p>\n

    -Elle permet de prot\u00e9ger la berge de fa\u00e7on sp\u00e9cifique dans la zone o\u00f9 elle est sollicit\u00e9e par les turbulences, sans avoir \u00e0 la d\u00e9velopper sur l\u2019ensemble du rampant de la berge.<\/p>\n

    -L\u2019\u00e9paisseur de la protection gabions est seulement de 30cm contre 1m20 pour des enrochements, ce qui r\u00e9duit consid\u00e9rablement les volumes de mat\u00e9riaux \u00e0 transporter et \u00e0 mettre en \u0153uvre et limite l\u2019empreinte carbone du chantier.<\/p>\n

    L\u2019entreprise Maia Fondations, titulaire du march\u00e9, a confi\u00e9 \u00e0 France Maccaferri la fourniture et la pr\u00e9fabrication des matelas gabions pr\u00e9remplis pour prot\u00e9ger les 190m de berges. Des structures sp\u00e9cialement con\u00e7ues pour cette application ont \u00e9t\u00e9 propos\u00e9es, les RenoMac Plus. Le matelas inf\u00e9rieur a \u00e9t\u00e9 personnalis\u00e9 avec l\u2019ajout d\u2019un grillage doubl\u00e9 de g\u00e9otextile de 14m de longueur, destin\u00e9 \u00e0 \u00eatre ancr\u00e9 en t\u00eate de berge dans une tranch\u00e9e d\u2019ancrage.<\/p>\n

    Lors des reconnaissances de la berge r\u00e9alis\u00e9es par Maia fondations, il est apparu que la berge \u00e9tait compos\u00e9e de mat\u00e9riaux vasards h\u00e9t\u00e9rog\u00e8nes. France Maccaferri a alors propos\u00e9 de lester le grillage par la mise en place d\u2019un gabion pr\u00e9rempli CubiMac dans les zones o\u00f9 la tranch\u00e9e ne pouvait \u00eatre r\u00e9alis\u00e9e.<\/p>\n
