Fiabilit\u00e9 et rapidit\u00e9: le r\u00e9sultat de la connaissance et de l’organisation<\/h2>\n

Le pont sur le fleuve Tagliamento se compose de deux ponts (un dans chaque direction) dont chacun a une largeur de 20,30 m. L’ouvrage consiste en deux viaducs c\u00f4te \u00e0 c\u00f4te, chacun avec une chauss\u00e9e de 1 520 m de long compos\u00e9e de 19 trav\u00e9es sur 20 piles, avec une port\u00e9e typique de 81,6 m. Le tablier a une hauteur typique de 3,20 m avec une augmentation pr\u00e8s des piliers jusqu’\u00e0 une hauteur maximale de 4,00 m. Le type de pr\u00e9contrainte utilis\u00e9 est celui m\u00e9lang\u00e9 avec des c\u00e2bles internes et externes. L’assemblage a \u00e9t\u00e9 r\u00e9alis\u00e9 en porte-\u00e0-faux \u00e9quilibr\u00e9s. La disposition statique finale des tabliers est donc une poutre continue divis\u00e9e par des joints de dilatation. Les longueurs des voussoirs, qui ont un poids maximum de 110 tonnes, ont des valeurs variables: 1,60 m pour les segments de pieux, 2,67 m pour les segments de section variable et 2,85 m pour les segments de section constante.<\/p>\n

Les segments ont \u00e9t\u00e9 r\u00e9alis\u00e9s dans une usine de pr\u00e9fabrication de 33 000 m2, construite sp\u00e9cifiquement pour les travaux et situ\u00e9e \u00e0 proximit\u00e9 de la zone d’installation finale.<\/p>\n

Le transport des segments de la zone de pr\u00e9fabrication \u00e0 la zone d’installation a eu lieu avec des chariots en caoutchouc tandis que l’assemblage a \u00e9t\u00e9 r\u00e9alis\u00e9 avec une poutre de lancement sp\u00e9cialement con\u00e7ue.<\/p>\n

Le grand niveau d’organisation et de contr\u00f4le, en plus de la haute qualit\u00e9 des syst\u00e8mes de pr\u00e9fabrication, a permis la production de segments avec des tol\u00e9rances de fabrication de +\/- 2 mm et un assemblage tr\u00e8s rapide, r\u00e9duisant consid\u00e9rablement le temps initialement pr\u00e9vu.<\/p>\n","protected":false},"featured_media":1022,"template":"","tipo-impalcato":[25],"impiego":[16],"area-geografica":[3,40,27],"class_list":["post-199","referenze","type-referenze","status-publish","has-post-thumbnail","hentry","tipo-impalcato-conci","impiego-pont-autoroutier","area-geografica-italia","area-geografica-latisana","area-geografica-udine"],"acf":[],"yoast_head":"\nNouveau pont sur la rivi\u00e8re Tagliamento - Extension de l'Autostrada A4 - SPIC s.r.l.<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.spicsrl.com\/fr\/references\/nouveau-pont-sur-la-riviere-tagliamento-extension-de-lautostrada-a4\/\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Nouveau pont sur la rivi\u00e8re Tagliamento - Extension de l'Autostrada A4 - SPIC s.r.l.\" \/>\n<meta property=\"og:description\" content=\"Fiabilit\u00e9 et rapidit\u00e9: le r\u00e9sultat de la connaissance et de l’organisation Le pont sur le fleuve Tagliamento se compose de deux ponts (un dans chaque direction) dont chacun a une largeur de 20,30 m.
