Description of the Related Art Conventionally, as a method of preventing the collapse of the ground such as a slope of a river embankment or the slope of a mountain or the like and greening, a lawn is vegetated on the surface of the ground and the surface is strengthened by a binding force of a root. A method to cover the ground with a concrete structure, cover the surface of the ground with a concrete structure, build up the soil on the surface and vegetate grass, or cover the surface of the ground with a porous concrete structure. A method of growing grass has been developed.

た。In the conventional methods as described above, in the case where vegetation such as lawn is directly applied to the ground surface, the surface protection is often insufficient. In addition, the conventional method of embedding the soil on the surface of a concrete structure and applying vegetation thereto requires a large amount of soil and is easily washed away by rainwater. There is a problem that it is not suitable for a part that can be washed.

問題があった。[0006] A conventional method of planting grass on artificial mat-shaped artificial soil and transplanting the same together with the artificial soil can be considered as a method of greening the ground protection surface with a concrete structure. The growth of grasses due to simplicity of transplanting, and especially in the case of a mat made of synthetic resin fiber, is advantageous in terms of the large amount of soil retained, but when this is used on slopes such as embankments However, there has been a problem that the entire mat is easily peeled off by running water, and is easily washed away when the water is increased.

In particular, the purpose of the present invention is to provide a revegetation base and a revegetation method in which a sufficient revetment function is obtained in a portion of the embankment that is exposed to flowing water at the time of rising water, and the revetment is hard to be washed away by flowing water.
