    Les fortes pluies de d\u00e9cembre 2021 sur la commune de l\u2019Alpe d\u2019Huez ont engendr\u00e9es une zone de glissement situ\u00e9e au niveau du talus du parking des Bergers. La stabilit\u00e9 de la rue du Rif Briant se trouvant juste au-dessus \u00e9tait alors engag\u00e9e. La commune de l\u2019Alpe d\u2019Huez a envisag\u00e9 une solution efficace de confortement.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Dans le cadre de la consolidation du talus des Bergers, la commune de l’Alpe d’Huez a souhait\u00e9 une solution de confortement permettant d\u2019augmenter la r\u00e9sistance au cisaillement des remblais et de reconstituer une but\u00e9e efficace sous la niche d\u2019arrachement pour s\u2019affranchir d\u2019un risque de recul du glissement. Pour atteindre cet objectif et dans un contexte topographique difficile, la solution consiste en la mise en \u0153uvre de structures de type READYMAC afin de cr\u00e9er une accroche des remblais de reprofilage dans la pente. France Maccaferri a fourni les notes de calcul de dimensionnement des ReadyMac et a su adapter ses structures de mani\u00e8re \u00e0 proposer des demi-structures \u00e0 installer en d\u00e9but et fin de talus, afin de s’adapter \u00e0 la morphologie du terrain. <\/p>\n

    Les structures ReadyMac pr\u00e9assembl\u00e9es et polyvalentes sont faciles, l\u00e9g\u00e8res et rapides \u00e0 installer. La structure en acier est fix\u00e9e au talus avec des ancrages (au centre et \u00e0 la base de la croix).<\/p>\n

    La structure souple du ReadyMac est possible gr\u00e2ce au grillage double torsion. Ce grillage poss\u00e8de un rev\u00eatement en GALFAN (95% zinc et 5% d\u2019aluminium) plus une couronne extrud\u00e9e en polym\u00e8re POLIMAC permettant d’augmenter la dur\u00e9e de vie du produit (dur\u00e9e de vie sup\u00e9rieur \u00e0 100 ans (NF EN 10223-3) dans un environnement tr\u00e8s agressif (C4-ISO 9223)) \u00e9tant donn\u00e9 que le grillage est en contact avec le terrain. Il est possible de combiner la structure ReadyMac avec d’autres \u00e9l\u00e9ments. Dans le cadre de ce chantier, un ouvrage en sol clou\u00e9 a \u00e9t\u00e9 r\u00e9alis\u00e9 avec un grillage \u00e0 haute r\u00e9sistance (SteelGrid HR 30) coupl\u00e9 avec une bionatte anti-erosive en coco (BioMac). Le SteelGrid HR 30 est un g\u00e9ocomposite m\u00e9tallique fabriqu\u00e9 avec du grillage \u00e0 mailles hexagonales double torsion et des c\u00e2bles m\u00e9talliques, tiss\u00e9s longitudinalement dans la maille au cours de la fabrication chaque 30 cm.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
