Le secteur des travaux est localis\u00e9 au lieu-dit Pas des Aigues, en bordure de l\u2019Orb, sur la commune de S\u00e9rignan le long de la voie cyclable entre la RD37E11 et les Orpelli\u00e8res. Les pr\u00e9sents travaux concernent la restauration et la protection des berges de l\u2019Orb au droit de deux \u00e9rosions, localis\u00e9es aux Pas des Aigues amont et pas des Aigues aval. Ces \u00e9rosions avaient provoqu\u00e9 \u00e0 certains endroits le glissement de la chauss\u00e9e. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Afin de renforcer la protection anti-affouillement au niveau des zones sensibles, des matelas gabion d\u2019\u00e9paisseur 30cm ont \u00e9t\u00e9 dispos\u00e9s en fond de lit sur un lin\u00e9aire de berge de 70 m et une largeur de 16 m afin de couvrir environ 1\/3 du lit. Cette protection n\u00e9cessitant une installation en eau, la confection et la mise en \u0153uvre des Matelas Reno s’est faite depuis le haut de berge \u00e0 la grue mobile. Pour ce type d’application, Maccaferri propose le Matelas Reno double diaphragme \u00e0 d\u00e9bords, muni d’un double fond encapsulant le g\u00e9otextile en sous face, de suspentes de levage int\u00e9gr\u00e9es et de d\u00e9bords assurant la jonction entre chaque matelas pos\u00e9s c\u00f4te \u00e0 c\u00f4te. Une plateforme a \u00e9t\u00e9 am\u00e9nag\u00e9e afin de proc\u00e9der aux op\u00e9rations d’assemblage et remplissage des structures. Manutentionn\u00e9s \u00e0 l’aide d’un palonnier, les Matelas Reno double diaphragme \u00e0 D\u00e9bords ont \u00e9t\u00e9 pos\u00e9s avec l\u2019accompagnement de plongeurs pour assurer l’emplacement de chaque matelas de 4x2m suivant le calepinage pr\u00e9vu. Les matelas ont \u00e9t\u00e9 agraf\u00e9s ou ligatur\u00e9s en eau au moyen d\u2019un c\u00e2ble inox 8mm afin de ne constituer qu\u2019un bloc entre le pied de berge et l\u2019axe du lit. Les diff\u00e9rents l\u00e9s ont \u00e9t\u00e9 agraf\u00e9s entre eux au niveau de la berge dans les secteurs o\u00f9 la hauteur d\u2019eau est inf\u00e9rieure \u00e0 1 m, soit sur une bande de 2 \u00e0 3 m. En pied de berge, les matelas ont \u00e9t\u00e9 fix\u00e9s sur un rang de pieux bois de longueur 4 m avec un c\u00e2ble inox. Le grillage double torsion constituant les matelas est rev\u00eatu de Polimac, le rev\u00eatement Polym\u00e8re d\u00e9velopp\u00e9 par Maccaferri ultra r\u00e9sistant \u00e0 l’abrasion.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
