Abstract: A vacuum consolidation dredging method has been developed in which an airtight loading box with a bottom opening is used and which involves vacuum consolidation and dredging in a single series. There are many different types of dredged soil, but, as a characteristic of said box, it is necessary to perform consolidation within an extremely short time, before the water content ratio of the soil being dredged is less than or equal to a liquid limit. Further, loading and unloading of dredged soil is problematic for conventional vacuum consolidation dredgers. As detachable structures, this box comprises a box lid and box tubes for dealing with different types of dredged soil, and different types of dredged soil are dealt with by merely replacing the box tubes on the ship. Further, this split consolidation system has ultra-fast consolidation in which, by means of an airtight loading box with a double box structure, an external box restrains the dredged soil and an internal box moves horizontally in centimeters, repeatedly performing consolidation. Further, as for loading and unloading of dredged soil by this vacuum consolidation dredger, by providing a function of temporarily integrating with a dedicated soil transport ship as an outrigger, loading and unloading of dredged soil can be performed quickly and stably.
