Abstract
A dredging tube system includes a tube unit and a plurality of spaced-apart sediment-trapping units. The tube unit includes a tube structure that has an inner surrounding surface surrounding a longitudinal axis. The sediment-trapping units are mounted fixedly on the inner surrounding surface and are arranged along the longitudinal axis. Each of the sediment-trapping units includes a plurality of sediment-trapping members that cooperatively form an annular ring structure. Each of the sediment-trapping members has an abutment portion that has a curved outer surface entirely abutting against the inner surrounding surface of the tube structure, and a projecting portion that extends radially and inwardly from the abutment portion.
