PROBLEM TO BE SOLVED: To provide a levee shaping machine capable of shaping an unshaped part of a levee caused by the length of a travelling machine body by stopping travelling of the travelling machine body and moving a levee shaping mechanism forward by a reciprocating mechanism while driving the levee shaping mechanism, and capable of continuously shaping the levee by driving the travelling machine body to turn in one direction along the levee.SOLUTION: A levee shaping mechanism 4 is dispose reciprocatably in a levee shaping direction by a guide mechanism 6 at a sideways position of a travelling machine body 1 so that an unshaped part T of a levee W caused by the machine length of the travelling machine body 1 can be shaped. A reciprocating mechanism 7 is provided for reciprocating the levee shaping mechanism. The guide mechanism has a multi-stage sliding structure D in which a plurality of moving frames 6c and 6e slide in multiple tiered stages. The reciprocating mechanism is composed of a plurality of hydraulic cylinders 7a and 7b for independently reciprocating the plurality of moving frames. |
