Sur la commune de Fontan, dans la vall\u00e9e de la Roya, tr\u00e8s touch\u00e9e lors de la temp\u00eate Alex en octobre 2020, des travaux de reconstruction ont \u00e9t\u00e9 r\u00e9alis\u00e9s afin de remettre en \u00e9tat les infrastructures ferroviaires. Dans la nuit du 2 au 3 octobre 2020, la temp\u00eate Alex avait coup\u00e9 toutes les liaisons dans la Vall\u00e9e de la Roya. L\u2019Etat, la R\u00e9gion Provence-Alpes-C\u00f4te d’Azur, le D\u00e9partement des Alpes-Maritimes, SNCF R\u00e9seau et les \u00e9quipes de NGE Fondations ont donc travaill\u00e9 ensemble afin de r\u00e9tablir la ligne dans les meilleurs d\u00e9lais. Apr\u00e8s d\u2019importantes op\u00e9rations de confortement et de s\u00e9curisation d\u2019un talus \u00e9rod\u00e9 7 mois apr\u00e8s la catastrophe, le tron\u00e7on ferroviaire reliant Breil-sur-Roya \u00e0 Tende a pu \u00eatre remis en service le lundi 3 mai dans la matin\u00e9e. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Afin de s\u00e9curiser le talus sur lequel repose un ouvrage SNCF (un mur en arcatures de 70 m de long sur lequel circule la ligne ferroviaire), l\u2019entreprise France Maccaferri a \u00e9t\u00e9 sollicit\u00e9e pour fournir le MacMat HS 30. Le Macmat\u00ae HS est un produit composite sp\u00e9cialement destin\u00e9 \u00e0 la protection de talus meubles ou rocheux en filets plaqu\u00e9s ou en parement de paroi clou\u00e9e. Il associe en usine un filet \u00e0 haute r\u00e9sistance Steelgrid (grillage double torsion renforc\u00e9 par des c\u00e2bles m\u00e9talliques ins\u00e9r\u00e9s longitudinalement dans le grillage \u00e0 des emplacements variables) \u00e0 un g\u00e9omatelas MacMat en polypropyl\u00e8ne. Ce grillage composite pr\u00e9sente une r\u00e9sistance \u00e9lev\u00e9e \u00e0 la traction, tout en assurant une protection locale contre l\u2019\u00e9rosion superficielle en facilitant la pouss\u00e9e de la v\u00e9g\u00e9tation. Il prot\u00e8ge la surface expos\u00e9e de l\u2019\u00e9rosion, assure la stabilit\u00e9 le temps que la v\u00e9g\u00e9tation soit install\u00e9e, r\u00e9alise une jonction entre les \u00e9l\u00e9ments superficiels instables et la partie profonde et stable de la pente. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
