    Le projet vise \u00e0 s\u00e9curiser la paroi rocheuse situ\u00e9e le long de la ligne ferroviaire Culoz\u2013Modane, entre Saint-Julien-Montricher et Saint-Michel-Valloire, sur le secteur du Pas du Roc (km 218+373 \u00e0 218+610). Ce secteur, tr\u00e8s fissur\u00e9 et expos\u00e9 aux chutes de blocs depuis les ann\u00e9es 1960, devait \u00eatre s\u00e9curis\u00e9 par l’installation de nouveaux \u00e9crans pare-blocs. Ces dispositifs permettent de se prot\u00e9ger contre la chute de blocs en cas de d\u00e9faillance des filets de protection active plac\u00e9s plus en amont, lesquels pr\u00e9sentent actuellement des signes de corrosion.<\/span><\/p>\n

    Ainsi, la protection passive est assur\u00e9e par un \u00e9cran de couloir de 1 000 kJ, une barri\u00e8re de 1 500 kJ et une barri\u00e8re qui garantit une protection \u00e0 l\u2019\u00e9nergie de service (SEL) de 2 200 kJ.<\/span><\/p>\n

    L\u2019intervention respecte des contraintes environnementales strictes (pr\u00e9sence de zones Natura 2000 et ZNIEFF), impose des m\u00e9thodes acrobatiques et des coupures ferroviaires, et se d\u00e9roule entre septembre et novembre 2024.<\/span><\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Maccaferri a dimensionn\u00e9 l\u2019\u00e9cran de couloir de 1 000 kJ, qui pr\u00e9sente des composants similaires \u00e0 la RB 1000, mais est adapt\u00e9 \u00e0 une configuration sans poteaux. Pour r\u00e9pondre aux besoins de protection au SEL de 2 200 kJ, une barri\u00e8re RB9000 de Maccaferri a \u00e9t\u00e9 fournie, capable d\u2019arr\u00eater un bloc d\u2019\u00e9nergie de 9 000 kJ \u00e0 l\u2019\u00e9tat limite ultime (MEL), ou un bloc de 3 000 kJ \u00e0 l\u2019\u00e9tat limite de service (SEL), garantissant ainsi une protection r\u00e9siduelle en cas d\u2019impacts ult\u00e9rieurs et cela satisfait l\u2019objectif de la SNCF qui est de garantir le service ferroviaire en cas d\u2019impact \u00e0 2200kJ.<\/span><\/p>\n

    La barri\u00e8re a \u00e9t\u00e9 modifi\u00e9e pour permettre la connexion de la RB 1500 (celle-ci dimensionn\u00e9e au MEL) directement sur un poteau de la RB 9000. En raison de l\u2019agressivit\u00e9 environnementale du site (C3 selon NF EN ISO 9223), toutes les barri\u00e8res ont \u00e9t\u00e9 fournies avec une protection avanc\u00e9e contre la corrosion. C\u2019est-\u00e0-dire, une galvanisation en alliage de zinc et aluminium (Zn95%Al5%), de classe A (NF EN 10244-2), a \u00e9t\u00e9 appliqu\u00e9e afin de garantir une dur\u00e9e de vie contre la corrosion de 25 ans. Maccaferri a \u00e9galement particip\u00e9 \u00e0 l\u2019implantation de la barri\u00e8re et a fourni un certificat de correcte installation lors de la r\u00e9ception.<\/span><\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
