Dans le cadre de la cr\u00e9ation d’une voie verte de 1400m sur l’itin\u00e9raire cyclable de Saint Jacques de Compostelle, des ouvrages de sout\u00e8nement devaient \u00eatre r\u00e9alis\u00e9s sur les bords de la Loire \u00e0 Rochecorbon. Ils avaient pour but le raidissement et la stabilisation des talus c\u00f4t\u00e9 Loire.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Les ouvrages de sout\u00e8nement ont \u00e9t\u00e9 r\u00e9alis\u00e9s en remblai renforc\u00e9 Terramesh Vert \u00e0 parement v\u00e9g\u00e9talis\u00e9. Le Terramesh vert est un grillage combin\u00e9 en parement \u00e0 un g\u00e9otextile tiss\u00e9 qui a pour r\u00f4le de prot\u00e9ger le remblai renforc\u00e9 d\u2019une \u00e9rosion superficielle et ce jusqu\u2019\u00e0 la compl\u00e8te v\u00e9g\u00e9talisation du parement. Un coffrage perdu en treillis soud\u00e9 est incorpor\u00e9 au parement pour assurer la r\u00e9gularit\u00e9 de celui-ci. Le parement v\u00e9g\u00e9talisable et la nappe de renfort sont r\u00e9alis\u00e9s avec une seule et m\u00eame nappe de grillage double torsion \u00e0 maille hexagonale de type 8×10 avec un fil de diam\u00e8tre 2.2\/3.2mm en acier galvanis\u00e9 de type Galmac classe A et plastifi\u00e9 (selon normes NF EN 10244 et 10245). La dur\u00e9e de service estim\u00e9e du rev\u00eatement dans des conditions environnementales tr\u00e8s agressives est de 120 ans (NF EN 10223-3). L’ouvrage r\u00e9alis\u00e9 est un remblai renforc\u00e9 \u00e0 parement inclin\u00e9 de 70\u00b0 par rapport \u00e0 la verticale et dont la hauteur est comprise entre 1.52 et 3.04m suivant les profils. Au total, 8 murs en remblai renforc\u00e9 ont \u00e9t\u00e9 r\u00e9alis\u00e9s pour un lin\u00e9aire total de 663m. Afin de reprendre les efforts en t\u00eate du mur, un grillage de renforcement a \u00e9t\u00e9 dispos\u00e9 sur le module de t\u00eate du Terramesh Vert. Ce dernier aura une longueur totale de 2m dont 20cm seront utilis\u00e9s pour assurer le recouvrement avec le module de Terramesh Vert. Un g\u00e9ocomposite de drainage est n\u00e9cessaire \u00e0 l\u2019arri\u00e8re du mur de sout\u00e8nement pour collecter les eaux d\u2019infiltration, \u00e0 l\u2019interface entre le remblai du corps de digue et le remblai structurel : un g\u00e9ocomposite de drainage de type Macdrain W1051 a donc \u00e9t\u00e9 mis en place. Ce sont les \u00e9quipes de Maccaferri qui se sont charg\u00e9es de la mise en \u0153uvre des murs.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
