RAINWATER INFILTRATION PROMOTION FACILITY
To more efficiently suppress rainwater from flowing out of a site as surface drainage.SOLUTION: A rainwater infiltration promotion facility 1A according to an embodiment has a multilayer structure 60 including a planting soil layer 10 placed on top of an existing soil 2, and a promotion layer 20 disposed between the planting soil layer 10 and the existing soil 2 to facilitate drainage from the planting soil layer 10 to the existing soil 2. The water permeability of the promotion layer 20 is higher than that of the planting soil layer 10, and the capillary pressure of the promotion layer 20 is higher than that of the planting soil layer 10.SELECTED DRAWING: Figure 1
【課題】雨水が表面排水として敷地外へと流出することをより効率的に抑制する。【解決手段】第一実施形態にかかる雨水浸透促進施設１Ａは、既存の土２の上側に配置された植栽土壌層１０と、植栽土壌層１０と既存の土２との間に配置され、植栽土壌層１０から既存の土２への排水を促進する促進層２０と、を含む多層構造部６０を備え、促進層２０の透水性は、植栽土壌層１０の透水性よりも高く、促進層２０の毛管圧は、植栽土壌層１０の毛管圧よりも高い。【選択図】図１
