Since this embodiment has the above structure,
When the traveling machine body 1 is run along the old ridge and the power take-off shaft 9 is rotated, the embankment rotor 19 of the embankment mechanism 17 continuously lifts up the mud of the ridge and the old ridge W onto the old ridge to raise it. On the other hand, the rectifying mechanism 4 is driven by using the power take-out shaft 9 of the traveling machine body 1 as a drive source, and the arranging body 16 is brought into rotational contact with the ridge surface and the ridge W surface can be tightened by the rotary arranging. By increasing the rotation speed of the rotary ridged body 15 as the ridged body 16 with respect to the traveling speed of the rotary ridged body 15, the rotary ridged body 15 makes a rotational sliding contact with the ridge W surface, and the rotary sliding contact makes the ridge W surface smooth and smooth.
