Tunnels<\/strong><\/h1>\r\n

Innovation dans la gestion des d\u00e9blais des tunnels<\/em><\/h2>\r\n

\r\n\t\t\tAper\u00e7u de la question\t<\/h3>\r\n\t

Les tunneliers \u00e0 pression de terre \u00e9quilibr\u00e9e (EPB) sont utilis\u00e9s dans la construction de tunnels ferroviaires, de m\u00e9tros, de tunnels autoroutiers et d'autres projets o\u00f9 le tunnel sera construit en partie ou en totalit\u00e9 dans un sol meuble.<\/p>\r\n

Dans de nombreux projets de creusement de tunnels, une grande quantit\u00e9 de boue est g\u00e9n\u00e9r\u00e9e. Des lubrifiants de forage \u00e0 base de bentonite, des mousses lubrifiantes et d'autres additifs sont utilis\u00e9s pour maintenir la pression sur la surcharge et r\u00e9duire la friction sur les grandes t\u00eates de coupe rotatives situ\u00e9es \u00e0 l'avant des tunneliers.<\/p>\r\n

La quantit\u00e9 de lubrifiant utilis\u00e9e d\u00e9pend de la g\u00e9ologie travers\u00e9e. Le lubrifiant facilite \u00e9galement le transport des d\u00e9bris g\u00e9n\u00e9r\u00e9s vers l'arri\u00e8re du tunnelier, o\u00f9 ils sont achemin\u00e9s vers la surface par un syst\u00e8me de convoyeur ou un chariot \u00e0 boue. Lorsque ces d\u00e9chets arrivent \u00e0 la surface, ils ont la consistance d'une boue, dont l'\u00e9limination est souvent difficile et co\u00fbteuse.<\/p>\r\n

Le processus d'\u00e9limination de la boue se d\u00e9roule souvent de la mani\u00e8re suivante :<\/p>\r\n

    \r\n
  1. Des camions aspirateurs sp\u00e9cialis\u00e9s transportent la boue jusqu'\u00e0 une station de transfert.<\/li>\r\n
  2. Des agents de gonflement tels que la sciure de bois sont utilis\u00e9s (ils gonflent g\u00e9n\u00e9ralement la boue de 50-200%).<\/li>\r\n
  3. Les camions-bennes transportent l'augmentation de la charge de d\u00e9chets vers un site d'\u00e9limination finale.<\/li>\r\n<\/ol>\r\n

    Cela signifie plus de camions n\u00e9cessaires, plus de temps perdu, plus d'\u00e9missions de gaz \u00e0 effet de serre et des co\u00fbts d'\u00e9limination plus \u00e9lev\u00e9s. Les m\u00e9thodes traditionnelles peuvent \u00e9galement produire des d\u00e9chets au pH \u00e9lev\u00e9, cr\u00e9er des d\u00e9chets corrosifs et dangereux, et modifier la classification des d\u00e9chets.<\/p>\r\n

    \r\n\t\t\tOverview of MetaFLO’s product\t<\/h3>\r\n\t

    MetaFLO fournit des r\u00e9actifs de solidification inertes* et non toxiques qui absorbent rapidement l'eau sur le site et aident les d\u00e9chets \u00e0 passer le test du filtre \u00e0 peinture (PFT). Ils peuvent \u00eatre appliqu\u00e9s \u00e0 la boue g\u00e9n\u00e9r\u00e9e par les tunneliers EPB afin de solidifier les d\u00e9chets plus efficacement que les m\u00e9thodes traditionnelles. Le dosage varie en fonction du taux d'humidit\u00e9 de la boue.<\/p>\r\n

    Avec MetaFLO, l'\u00e9limination de la boue est optimis\u00e9e :<\/p>\r\n

      \r\n
    1. MetaFLO’s technology solidifies the slurry on-site<\/li>\r\n
    2. La boue solidifi\u00e9e est transf\u00e9r\u00e9e dans des camions-bennes pour \u00eatre transport\u00e9e directement vers le site d'\u00e9limination final.<\/li>\r\n<\/ol>\r\n

      Our solidification reagents can be applied at the surface, or at the source, using muck conveyor belts to begin the solidification process early-saving time and labour.<\/p>\r\n

      *La classification des produits peut varier d'une juridiction \u00e0 l'autre dans les diff\u00e9rents pays.<\/em><\/p>\r\n\t\t\t\t\"M\u00e9thode-FR\"\r\n

      2. Am\u00e9lioration de l'efficacit\u00e9 des transports pour \u00e9vacuer les mat\u00e9riaux secs des sites de projet<\/li>\r\n
      3.
