Abstract

PURPOSE:To perform excavation and dredging work without lifting the bucket of an oil-pressure shovel up to the water surface by using a system in which the suction pipe of a vacuum pump is attached to the inside of the bucket. CONSTITUTION:A bucket 2 is wound and retreated by the operation of an oil- pressure shovel 1. Dredging work is performed while sucking up excavated soil and sand through a suction pipe port 3 inside the bucket 2 by operating a vacuum pump unit 4.
