Dans le cadre du march\u00e9 \u00e0 bon de commande du d\u00e9partement des Alpes Maritimes, le Frachet situ\u00e9 en amont du village de Saint-Sauveur-sur-Tin\u00e9e a \u00e9t\u00e9 class\u00e9 comme l\u2019une des op\u00e9rations prioritaires en raison de l\u2019al\u00e9a tr\u00e8s \u00e9lev\u00e9, de la pr\u00e9sence de la route d\u2019acc\u00e8s \u00e0 la Haute Tin\u00e9e et aux stations de ski du Mercantour (RN2205) et de la fr\u00e9quence \u00e9lev\u00e9e des \u00e9boulements recens\u00e9s \u00e0 cet endroit. La M\u00e9tropole Nice Cote d’Azur a sollicit\u00e9 la Soci\u00e9t\u00e9 EPC France afin de mettre en place des solutions de protection. La premi\u00e8re phase, r\u00e9alis\u00e9 en 2019, consistait \u00e0 r\u00e9aliser des avaloirs (ou barri\u00e8res hybrides implant\u00e9es dans chaque vallon) pr\u00e9sentant des dimensions importantes, peu courantes pour un tel ouvrage.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Apr\u00e8s analyse du projet, France Maccaferri a r\u00e9alis\u00e9 le dimensionnement, les notes de calcul justifiant les composants et les coupes types de d\u00e9tails pour la fourniture d’\u00e9crans d\u00e9flecteurs hybrides, con\u00e7us pour reprendre une \u00e9nergie de projet de 3000 kJ. L’ensemble a \u00e9t\u00e9 soumis \u00e0 la maitrise d\u2019\u0153uvre, qui a valid\u00e9 le proc\u00e9d\u00e9. Le chantier a \u00e9t\u00e9 r\u00e9alis\u00e9 en 2 phases. Une fois l’installation des d\u00e9flecteurs termin\u00e9e (2050m\u00b2), une autre probl\u00e9matique a \u00e9t\u00e9 soulev\u00e9e : il fallait assurer la continuit\u00e9 de la protection entre les deux \u00e9crans d\u00e9flecteurs. France Maccaferri a alors dimensionn\u00e9 cette protection en ajoutant 700m\u00b2 de filets MacRing suppl\u00e9mentaires (certifi\u00e9s CE et test\u00e9s selon ISO 17745).<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
