Description of the Related Art A spraying method is known in which mortar or concrete is sprayed on a slope to stabilize the slope in order to prevent weathering or collapse of the rock mass. In addition, as one of the slope stabilization methods, there is also known a vegetation method in which after forming a legal framework on the slope, the slope is covered with sediment called soil, and then seeds and plants are planted in the soil.

【発明が解決しようとする問題点】前記した従来の斜面
安定化工法には次のような問題点がある。The conventional slope stabilizing method described above has the following problems.

Therefore, water sprinkling can be considered as a measure for preventing the death of plants and the like, but the human burden and the economic burden are large.

う。<D> In the vegetation method, it takes a considerable amount of time for the soil to form an integral layer with the ground on the slope. Moreover, the permeability of the ground on the slope is poor for the soil. Therefore, if there is rainfall that cannot be absorbed by the soil, it will wash away the sediment inside the soil when it flows down the surface of the slope.

Permeate into the water and flow down along the water-permeable mat 4. If the water-permeable mat 4 does not exist, rainfall may flow down the surface of the protective layer 1 and the lower layer of the soil 8 may be washed away. However, since the water-permeable mat 4 is interposed between the protective layer 1 and the soil 8, a drainage channel is formed inside the water-permeable mat 4, and the above-mentioned flow of the soil 8 can be effectively prevented. .

In such a situation, water is supplied to the soil 8 from the water supply rope 5 buried in the soil 8. If water is included in the water permeable mat 4 as well as the water supply rope 5,
Since water is supplied from the water-permeable mat 4 to the soil 8, it is possible to maintain a suitable growth environment for the plants even if the sunshine continues for a long time.
