Zusammenfassung:PROBLEM TO BE SOLVED: To provide a dredging method which can efficiently perform work by enhancing a mud content and reducing the number of operations of scooping sediment when dredging is performed at a predetermined depth. SOLUTION: The dredging is performed with a finishing depth t left with respect to a preset dredging depth D by means of a first bucket lifted and lowered via a hanging wire 10a by a winch device 13. After that, a finishing bucket 1, which has a maximum digging depth set smaller than that of the first bucket and has a maximum opening area set larger than that of the first bucket is attached to the hanging wire 10a in place of the first bucket, and finishing digging is performed at the finishing depth t by means of the finishing bucket 1.
