In the structure described in the above publication, when the embankment is compacted with respect to the old ridge, the embankment is applied with the same pressure on the conical surfaces of the inner rotary plate and the outer rotary plate or the inner rotary plate. Since it tries to compact it with, the effect of compacting the embankment while pressing it strongly against the side surface of the old ridge is small, and the embankment cannot be sufficiently compacted against the side surface of the old ridge. There is a problem that the ridges are relatively softly finished, and the ridges are liable to collapse and are unfavorable for lining the ridges that are durable for a long period of time.

Therefore, it is conceivable that a conical repair surface for repairing the side surface of the old ridge is formed into a polyhedral shape, and the mud is compacted on the side surface of the old ridge by the multifaceted repair surface. However, in the configuration of this side restoration body, at each corner of the multifaceted restoration surface, the mud is scraped toward the side portion of the old ridge and pushed into the side portion of the old ridge, but at each corner of the restoration surface.
