Since the upper surface of the ridge and the upper surface of the ridge can be rotated at the same time, the upper surface of the ridge can be rotated and leveled at the same time. In the described invention, a through hole is formed between the pressing surfaces and the pressing is performed. Since the body is formed of a flexible plate, the ridge surface is more intermittently pressed by the through holes, so that the pressure can be firmly tightened and the pressing plate body bends due to flexibility. The embankment can be gradually compacted while the soil can be prevented from adhering to the outer periphery of the rotating ridge, and the ridge between the top and one side of the ridge can be squeezed well. Therefore, it is possible to perform a good ridge work and obtain a more robust ridge.

As described above, the intended purpose can be sufficiently achieved.
