PROBLEM TO BE SOLVED: To improve a drum-like levee shaper for restoring an original levee by applying mud for levee plastering cut by a filling body and supplied to an original levee part to the original levee while rotating.SOLUTION: (1) For a drum-like levee shaper 15 applied to an original levee to restore the original levee while rotating mud supplied by a filling body 5, a plurality of levee-shaping boards 15a are arranged at regular intervals circumferentially toward an outer peripheral side from the center of rotation, and the respective levee-shaping boards 15a are mutually connected by connection members 15b, 15c to form a step 15d at boundary parts of the respective levee-shaping boards 15a. (2) The levee-shaping boards 15a to which a levee-shaping drum is adjacent mutually have predetermined overlapping, and the vertical step 15d is formed at the overlapped part. (3) The plurality of levee-shaping boards 15a are connected together by the plurality of connection members 15b, 15c to form the levee-shaping drum. (4) A plurality of connection members 25c are composed in a plurality of sets, and at least one set of them is made attachable to and detachable from a levee-shaping board 25a. (5) For at least one set 28b from among a plurality of sets of connection members 28a, 28d, a fixed position 28c to a levee-shaping board 28a can be changed. |
