PROBLEM TO BE SOLVED: To provide a levee plastering machine capable of performing attachment/detachment work of an upper-face levee shaping part easily and quickly without requiring a new tool when attaching and detaching the same.SOLUTION: A levee plastering machine comprises: a slope-face levee shaping part, which is configured by connecting a plurality of slope-face blades in a circumferential direction, for shaping a slope face of a levee by rotation around an axis; an upper-face levee shaping part, whose base end part is fastened to the top part of the slope-face levee shaping part, for shaping an upper face of the levee by rotation around an axis; and a covering upper-face levee shaping part that covers the side wall surface and the top wall surface of the upper-face levee shaping part by inserting the upper-face levee shaping part in a nesting state and is attachable and detachable to and from the upper-face levee shaping part. The attachment/detachment work can be performed by rotating the covering upper-face levee shaping part with respect to the upper-face levee shaping part. On the inner surface of the side surface of the covering upper-face levee shaping part, a plurality of guide members for keeping a distance to the side wall surface of the upper-face levee shaping part constant in the circumferential direction as well as an axial direction are provided in the axial direction.SELECTED DRAWING: Figure 10 |
