Le site ferroviaire dit de \u00ab Ventenat \u00bb ne poss\u00e9dait pas d\u2019acc\u00e8s routier permettant d\u2019aller sur les faisceaux de voies de services. L\u2019implantation d\u2019une base travaux sur ce site n\u00e9cessitait donc la r\u00e9alisation d\u2019un acc\u00e8s routier. De plus, un am\u00e9nagement important de ces faisceaux de voies \u00e9tait n\u00e9cessaire pour permettre une circulation s\u00e9curis\u00e9 des camions au c\u0153ur de la base. Les travaux principaux ont consist\u00e9 en : \u00b7 la cr\u00e9ation d\u2019une rampe d\u2019acc\u00e8s depuis le pont route de Juillac situ\u00e9 sur la RD 250. \u00b7 l\u2019am\u00e9nagement d\u2019une piste routi\u00e8re permettant de desservir les futures aires de stockages et d\u2019entretiens du site de Ventenat. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

C’est pour la cr\u00e9ation de la rampe d’acc\u00e8s que Maccaferri a \u00e9t\u00e9 sollicit\u00e9 pour dimensionner, fournir et mettre en \u0153uvre les ouvrages de sout\u00e8nement en remblai renforc\u00e9s \u00e0 parement gabions. L\u2019ouvrage est un remblai renforc\u00e9 \u00e0 parement min\u00e9ral sub-vertical ayant une hauteur variable entre 1 et 9.5m. Pour la zone de plus grande hauteur o\u00f9 l\u2019emprise en pied est limit\u00e9e et o\u00f9 le terrain en place pr\u00e9sente du gneiss franc lors de l\u2019excavation, des gabions ont \u00e9t\u00e9 mis en \u0153uvre en pied d\u2019ouvrage sur une profondeur de 2m et sur au maximum 3m de haut. Le remblai renforc\u00e9 a \u00e9t\u00e9 r\u00e9alis\u00e9 en Terramesh System, constitu\u00e9 d’un parement min\u00e9ral de type gabion, qui se prolonge par une nappe de grillage m\u00e9tallique en arri\u00e8re de 3m de longueur. Ces structures sont fabriqu\u00e9es dans le cadre d\u2019un syst\u00e8me de qualit\u00e9 ISO 9001 et sont certifi\u00e9es CE. En conformit\u00e9 avec le cahier des charges le fil constituant le Terramesh dispose d’un rev\u00eatement plastifi\u00e9 pour assurer une meilleure durabilit\u00e9. Les structures ont \u00e9t\u00e9 associ\u00e9es \u00e0 des g\u00e9ogrilles de renfort Paragrid de longueur et d\u2019espacement variable en fonction de la hauteur (structures planes monodirectionnelles r\u00e9sultant de la soudure de bandes g\u00e9osynth\u00e9tiques entre elles). A l\u2019interface entre le terrain naturel et le remblai, un g\u00e9ocomposite de drainage Macdrain a \u00e9t\u00e9 mis en place entre le terrain naturel excav\u00e9 et le remblai structurel.Il s’agit d’un g\u00e9ocomposite de drainage r\u00e9alis\u00e9 par thermoliage d\u2019un noyau de drainage en monofilaments extrud\u00e9s avec deux g\u00e9otextiles non tiss\u00e9s filtrant.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
