Abstract

Un metodo per rinforzare e consolidare il terreno in qualsiasi direzione che comprende una fase di scavo per realizzare un foro nel terreno usando un'asta doppia di scavo composta da un membro esterno e da un membro interno mobile all'interno del membro esterno; una fase di ritrazione per ritrarre il membro interno dal membro esterno, in cui il membro esterno rimane nel foro; una fase di controllo per controllare il foro inserendovi un membro luminoso contenente una batteria; una fase di inserimento per inserire un'asta di iniezione dentro il membro esterno; una fase di regolazione della pressione nel foro; ed una fase di iniezione per iniettare un materiale rinforzante nel foro e ritrarre il membro esterno e l'asta d'iniezione consolidando il terreno.Un'apparecchiatura per attuare il metodo suddetto.
