In the background art, a block made of a natural stone or an artificial stone; A vegetation sheet disposed at a lower portion of the block and having a predetermined width and length and having plant seeds attached to its surface; A coconut fiber mat disposed between the block and the vegetation sheet and made of a coconut shell and having a surface woven in a lattice pattern using jute; A grid disposed at a lower portion of the vegetation sheet and having a net shape; And a set anchor penetrating through the grid and being press-fitted into the block.

However, the background art has a problem that the vegetation stone net is not fixed to the slope side, and the flow is lost if the flow velocity of the stream increases.

Korean Patent Registration No. 10-1224159 (module type stone net assembly) is proposed as another background of the present invention. In the above background art, there is provided a supporting net having a rectangular plate-like net structure, a plurality of stones, and a stone rest section for fixing the stones to the supporting net, Comprising: a stonet module; A module mutual fixing unit for mutually connecting and fixing neighboring supporting nets in a state in which the stone net modules are arranged in combination; And a plurality of first module ground fixing parts for fixing the support net to the installation surface, wherein after the stone net modules are disposed on the installation surface in combination, the respective stone net modules are connected and fixed through the module mutual fixing parts And each of the stone net modules is fixed to the mounting surface by the first module ground fixing part.

In this technique, if the ridge line is fixed with an anchor or the stone is resistant to the flow velocity, the fixing part is weakened, and the stone net may be lost.
