    Le Terramesh\u00c2\u00ae system est un syst\u00c3\u00a8me associant un gabion de fa\u00c3\u00a7ade \u00c3\u00a0 une nappe de renfort en grillage continue du parement. La partie gabion assure un parement soign\u00c3\u00a9 tandis que le renfort grillag\u00c3\u00a9 permet un renforcement du remblai arri\u00c3\u00a8re et la tenue du massif. En compl\u00c3\u00a9ment au grillage, des g\u00c3\u00a9ogrilles de renfort de type Paralink\u00c2\u00ae 300 et Paralink\u00c2\u00ae 400 ont \u00c3\u00a9t\u00c3\u00a9 ajout\u00c3\u00a9es sur une longueur de 20m dans le remblai pour apporter le renforcement n\u00c3\u00a9cessaire. Le grillage constitutif du Terramesh\u00c2\u00ae system est \u00c3\u00a0 maille hexagonale double torsion (ind\u00c3\u00a9maillable)rev\u00c3\u00aatu d’une gaine en PVC de 1mm d\u00e2\u0080\u0099\u00c3\u00a9paisseur. Cette protection du fil, particuli\u00c3\u00a8rement r\u00c3\u00a9sistante \u00c3\u00a0 la corrosion assure une dur\u00c3\u00a9e de service \u00c3\u00a0 l\u00e2\u0080\u0099ouvrage de 120 ans. Le dimensionnement de l\u00e2\u0080\u0099ouvrage a \u00c3\u00a9t\u00c3\u00a9 r\u00c3\u00a9alis\u00c3\u00a9 par le d\u00c3\u00a9partement technique de Maccaferri en utilisant le logiciel interne de stabilit\u00c3\u00a9 de pente MACSTARS afin de d\u00c3\u00a9finir la longueur, l\u00e2\u0080\u0099espacement et le type de renfort. La r\u00c3\u00a9alisation d\u00e2\u0080\u0099un ouvrage de sout\u00c3\u00a8nement d\u00e2\u0080\u0099une telle ampleur n\u00c3\u00a9cessite une mise en place soign\u00c3\u00a9e des structures et un strict respect de la proc\u00c3\u00a9dure travaux. MACCAFERRI a transmis une proc\u00c3\u00a9dure travaux compl\u00c3\u00a8te pour assister l\u00e2\u0080\u0099entreprise dans l\u00e2\u0080\u0099ensemble des \u00c3\u00a9tapes de r\u00c3\u00a9alisation de l\u00e2\u0080\u0099ouvrage. Les cages ont \u00c3\u00a9t\u00c3\u00a9 remplies avec des pierres extraites du site et concass\u00c3\u00a9es sur site. Pr\u00c3\u00a8s de 4000t de pierres ont ainsi \u00c3\u00a9t\u00c3\u00a9 n\u00c3\u00a9cessaires pour remplir les cages. En consid\u00c3\u00a9rant une concentration moyenne d\u00e2\u0080\u0099or de 5g\/t de pierres extraites, , le mur est constitu\u00c3\u00a9 d\u00e2\u0080\u0099environ 20kg d\u00e2\u0080\u0099or\u00c2\u00a0!<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
