ROOFTOP GREENING RAINWATER TEMPORARY STORAGE DEVICE
To provide a rooftop greening rainwater temporary storage device that, by temporarily storing rainwater poured on a rooftop of a building in the case where concentrated torrential rainfall occurs for example, can delay drainage onto the ground, eventually flowing into a river, and can suppress river flooding or flood disaster.SOLUTION: A rooftop greening rainwater temporary storage device that is constructed on a rooftop of a building structure of a water-resistant layer of a roof, and arranged in a greening region including soil has: a filter layer which is arranged below a gravity direction of the greening region, and restricts passing of soil but allows permeation of water; a water passage part which is arranged below a gravity direction of the filter layer; a storage part which is arranged in a horizontal direction for the greening region with a sidewall laid between them, and stores water which has permeated through the filter layer and entered via the water passage part; and a drainage port which discharges water from the storage part.SELECTED DRAWING: Figure 1
【課題】例えば集中豪雨が発生したような場合に、建物の屋上に降り注いだ雨水を一時的に貯留することにより、地上への排水、ひいては河川への流入を遅延させ、河川の氾濫や浸水害を抑制できる屋上緑化雨水一時貯留装置を提供する。【解決手段】建造物の屋上または屋根の防水層上に構築され、土壌を含む緑化領域内に配置される屋上緑化雨水一時貯留装置は、前記緑化領域の重力方向下方に配置され、土壌の通過を制限するが、水の透過を許容するフィルター層と、前記フィルター層の重力方向下方に配置された通水部と、前記緑化領域に対して水平方向に側壁を隔てて配置され、前記フィルター層を透過し、前記通水部を介して進入した水を貯留する貯留部と、前記貯留部から水を排出する排水口と、を有する。【選択図】図１
