FLOOD DISASTER RESISTING FACILITY WITH FLOOD RESISTING WALL
To provide an economical flood disaster resisting facility with a high safety which can resist an assumption water immersion depth and water pressure while minimizing a height of a flood resisting wall itself by combining a banking and the flood resisting wall.SOLUTION: A flood resisting wall 2 is constructed so that an upper end is equal to or greater than an assumption water immersion depth in the shape of surrounding a plurality of buildings 1a, 1b, 1c and 1d, when a water disaster occurs, an isolated space is formed between the building and the flood resisting wall by blocking an opening of the flood resisting wall to prevent damage inside. A range in which the flood resisting wall surrounds is arranged so that a banking E with a height of approximately 1.5 m is established and a height of an upper end of the flood resisting wall constructed on the banking soil is equal to or greater than an assumption water immersion depth, an inclined banking part Et as a transition zone T with the height increasing gradually toward the flood resisting wall is established outside of the flood resisting wall, and a safety design of the flood resisting wall is facilitated as a height of the flood resisting wall itself can be minimized for a height of the banking and a water pressure or wave pressure applied to the flood resisting wall 2 is reduced in the water disaster.SELECTED DRAWING: Figure 1
【課題】盛土と耐洪水塀を組み合わせることで、耐洪水塀自体の高さを抑えつつ、想定浸水深および水圧に耐え得る、経済的で安全性の高い耐水害施設を提供する。【解決手段】複数の建物１ａ、１ｂ、１ｃ、１ｄを取り巻く形で、上端部が想定される浸水深以上の高さとなるように耐洪水塀２を構築し、水害発生時には耐洪水塀の開口部を閉塞することで、建物と耐洪水塀との間に隔離された空間を形成し、内部への被害を防止する。耐洪水塀が取り巻く範囲は、例えば１．５ｍ程度の高さの盛土Ｅを造成し、盛土上に構築される耐洪水塀の上端部の高さが浸水深以上の高さとなるようにし、耐洪水塀の外側には耐洪水塀に向けて徐々に高さが増加する遷移区域Ｔとして勾配を有する盛土部分Ｅtが造成され、盛土の高さ分、耐洪水塀本体の高さを抑えることができ、水害時に耐洪水塀２受ける水圧や波圧も小さくなるため、耐洪水塀の安全設計が容易となる。【選択図】図１
