Abstract

PURPOSE:To perform dredging work while excavating the ground by a rotary bucket by using a system in which the suction pipe of a vacuum pump is attached to the inside of a wheel cutter attached to the tip of the ladder of a wheel cutter ship. CONSTITUTION:Dredging work is performed while sucking up soil and sand excavated by a rotary bucket 2 through a suction pipe port 3 in the inside of the rotary bucket 2 by the operation of a vacuum pump 4 in a wheel cutter ship 9.
