ともに法枠上を流下したりするといった問題があった。(Problems to be solved by the invention) However, this slope drainage method utilizes the difference in the density of the soil on the slope and the soil of the additional soil.
In cases where the density of the soil on the slope is low, rainwater that has permeated the soil can penetrate deep into the slope, raising the groundwater level within the slope and causing the slope to collapse. In addition, when the density of the soil is high, there is a problem in that rainwater does not permeate into the soil sufficiently and flows down along with the soil and sand over the legal framework.

This is done by filling each frame (14) to the same height as the frame (14). In addition, when planting vegetation, seeds and fertilizers mixed in soil may be filled in each frame (14) using a spraying method, or top soil may be added using a vegetation bag method. In this way, by filling each frame (14) of the slope with soil, rainwater (a) that falls on the slope (11) penetrates into the soil in the frame (I4) and is collected. This collected rainwater (a) reaches the drainage material (16)-H installed under the soil, passes through the water-permeable sheet (17) on the surface layer of this drainage material (16), and then (17), enters the water passage body (18) provided in the water passage body (18), is guided to the slope end (llb) of the slope (11) through this water passage body (18), and is drained. ing.
