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

Innovazione nella gestione dei rifiuti in galleria<\/em><\/h2>\r\n

\r\n\t\t\tIl problema in sintesi\t<\/h3>\r\n\t

Le TBM (Earth Pressure Balance Tunnel Boring Machines) sono utilizzate nella costruzione di gallerie ferroviarie, metropolitane, autostradali e in altri progetti in cui la galleria sar\u00e0 costruita in parte o completamente in terreno soffice.<\/p>\r\n

In molti progetti di scavo di gallerie, si genera una grande quantit\u00e0 di fango. I lubrificanti di perforazione a base di bentonite, le schiume lubrificanti e altri additivi vengono utilizzati per mantenere la pressione sul sovraccarico e ridurre l'attrito sulle grandi teste di taglio rotanti situate nella parte anteriore delle frese per tunnel.<\/p>\r\n

La quantit\u00e0 di lubrificante utilizzata dipende dalla geologia attraversata. Il lubrificante facilita anche il trasporto dei detriti generati verso la parte posteriore della fresa, dove vengono trasportati in superficie da un sistema di trasporto o da una macchina del fango. Quando questi rifiuti arrivano in superficie, hanno la consistenza del letame, spesso difficile e costoso da smaltire.<\/p>\r\n

Il processo di smaltimento del letame \u00e8 spesso simile a questo:<\/p>\r\n

    \r\n
  1. Autocarri specializzati nell'aspirazione trasportano il letame in una stazione di trasferimento.<\/li>\r\n
  2. Vengono utilizzati agenti di carica, come la segatura (che di solito aumenta la massa del liquame del 50-200%).<\/li>\r\n
  3. I dumper trasportano l'aumento del carico di rifiuti in un sito di smaltimento finale.<\/li>\r\n<\/ol>\r\n

    Ci\u00f2 significa pi\u00f9 camion necessari, pi\u00f9 tempo sprecato, maggiori emissioni di gas serra e maggiori costi di smaltimento. I metodi tradizionali possono anche produrre rifiuti con un pH elevato, creare rifiuti corrosivi e pericolosi e modificare la classificazione dei rifiuti.<\/p>\r\n

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

    MetaFLO fornisce reagenti di solidificazione inerti* non tossici che assorbono rapidamente l'acqua in loco e aiutano i rifiuti a superare il Paint Filter Test (PFT). Possono essere applicati al fango generato dalle TBM EPB per solidificare i rifiuti in modo pi\u00f9 efficiente rispetto ai metodi tradizionali. Il dosaggio varia in base al contenuto di umidit\u00e0 del fango.<\/p>\r\n

    Con MetaFLO, lo smaltimento del letame \u00e8 ottimizzato:<\/p>\r\n

      \r\n
    1. MetaFLO’s technology solidifies the slurry on-site<\/li>\r\n
    2. Il liquame solidificato viene trasferito su autocarri ribaltabili per essere trasportato direttamente al sito di smaltimento finale.<\/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 classificazione dei prodotti pu\u00f2 variare a seconda delle giurisdizioni dei diversi Paesi.<\/em><\/p>\r\n\t\t\t\t\"Metodo-EN\"\r\n

      Il nostro collaudato processo MetaFLO offre chiari vantaggi:<\/strong><\/h3>\r\n
        \r\n
      1. Riduzione dell'ingombro operativo in siti urbani congestionati per una rapida gestione dei rifiuti<\/li>\r\n
      2. Miglioramento dell'efficienza di trasporto per la rimozione del materiale secco dai siti di progetto<\/li>\r\n
      3. Spazzatura solidificata che soddisfa i criteri normativi per essere destinata direttamente a siti di riempimento puliti Minori emissioni di gas serra, migliore logistica urbana, gestione responsabile del suolo in eccesso<\/li>\r\n<\/ol>\r\n\t\t\t\t\"reagenti\r\n\t
