Les travaux faisant l’objet du pr\u00e9sent march\u00e9 concernaient la construction de l’ouvrage Passerelle BUS dans le cadre de l’am\u00e9nagement de la gare de p\u00e9age de l’ile de R\u00e9. Cet ouvrage est situ\u00e9 sur la commune de LA ROCHELLE. Il est destin\u00e9 \u00e0 permettre le franchissement de la RD 735 par les bus. L’ouvrage est du type PSIDP (Passage Sup\u00e9rieur ou inf\u00e9rieur Dalle Pr\u00e9contrainte), et d’une longueur totale de 51.70m. Des ouvrages de sout\u00e8nement devaient \u00eatre r\u00e9alis\u00e9s de part et d\u2019autres des rampes d\u2019acc\u00e8s \u00e0 la passerelle.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Maccaferri a r\u00e9alis\u00e9 les prestations de dimensionnement, de fourniture et pose des ouvrages. L\u2019ouvrage est un remblai renforc\u00e9 \u00e0 parement min\u00e9ral sub-vertical ayant une hauteur variable entre 1m50 et 4m suivant les profils. Cet ouvrage en remblai renforc\u00e9 est de type Terramesh System, avec un parement min\u00e9ral de type gabion, qui se prolonge par une nappe de grillage m\u00e9tallique en arri\u00e8re de 3m de longueur. Ces structures sont associ\u00e9es \u00e0 des g\u00e9ogrilles de renfort de type Paragrid 50 de longueur 3m ayant pour fonction de reprendre le surcroit d\u2019effort apport\u00e9 en cas accidentel en cas d\u2019impact de v\u00e9hicule sur le dispositif de s\u00e9curit\u00e9. Les \u00e9l\u00e9ments Terramesh ont une hauteur de 50cm et de 1m. Le parement gabion et la nappe de renfort sont r\u00e9alis\u00e9s avec une seule et m\u00eame nappe de grillage, \u00e0 base de grillage double torsion \u00e0 maille hexagonale de type 8×10 avec un fil galvanis\u00e9 2.7\/3.7mm de type GalMac (alliage Zn95%\/Al5%) de classe A et rev\u00eatu de polym\u00e8re (selon normes NF EN 10244 et 10245). Les structures Terramesh System sont certifi\u00e9es CE selon le R\u00e8glement des Produits de la Construction UE 305\/2011. Les g\u00e9ogrilles de renforts PARAGRID 50 sont des structures planes monodirectionnelles r\u00e9sultant de la soudure de bandes g\u00e9osynth\u00e9tiques entre elles. Les bandes g\u00e9osynth\u00e9tiques sont compos\u00e9es de faisceaux de fibres polyester de haute t\u00e9nacit\u00e9 enrob\u00e9es d\u2019une gaine en poly\u00e9thyl\u00e8ne. Elles sont certifi\u00e9es CE selon la Directive des Produits de construction 89\/106\/CEE, Asqual et BBA. Ces ouvrages ont \u00e9t\u00e9 mis en \u0153uvre par les \u00e9quipes de Maccaferri selon la norme de mise en \u0153uvre NFP 94325-1 et la certification Asqual sur la r\u00e9alisation des ouvrages en gabions (ROG).<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
