Abstract

PURPOSE:To perform excavation and dredging work without lifting a bucket up to the water surface by using a system in which the suction pipe port of a vacuum pump is attached to the inside of the bucket of clamshell. CONSTITUTION:A bucket 2 is opened by operating a clamshell 1 on a base ship 4. Dredging work is performed while sucking up excavated soil and san through a suction pipe port 3 provided inside the bucket 2 by operating a vacuum pump unit 5 provided on the land.
