PROBLEM TO BE SOLVED: To provide a levee plastering machine for facilitating an attaching and detaching operation of an upper levee-shaping body from a side levee-shaping body. SOLUTION: The levee plastering machine is equipped with a pretreatment part for cutting away a former levee and heaping up soil and a levee-shaping body 50 for plastering the heaped-up soil on the former levee, from which the heaped-up soil is cut away, while rotation. The levee-shaping body 50 has a conical side levee-shaping body 60 for forming the side of the former levee and a cylindrical upper levee-shaping body 51 for forming the upper part of the former levee. The upper levee-shaping body 51 is movable between an operation position Ps in which the upper levee-shaping body is supported through a supporting member 70 having a tip part rotating in the vertical direction by extension and contraction of a detachable cylinder 74 and connected to the side levee-shaping body 60 to form the upper part of the former levee and a nonoperation position Pn in which the upper levee-shaping body is retreated to a position not to be brought into contact with the side of the former levee when the side of the former levee is formed only by the side levee-shaping body 60. The detachable cylinder 74 is remote controlled by an operation from an operation switch attached to a traveling machine body. COPYRIGHT: (C)2009,JPO&INPIT
