RAINWATER STORAGE TANK
PROBLEM TO BE SOLVED: To provide a technology for enhancing strength in a vertical direction of a tank for resolving a problem with conventional tanks made of resin blocks that the tank could induce a creep phenomenon due to weight of a soil cover placed on top of the tank and fail to ensure sufficient strength in the vertical direction for long-term use.SOLUTION: A rainwater tank of the present invention is built in the following steps for: laying a block at a bottom part of the tank in underground, the block being assembled vertically and having a vertical guide hole; inserting a column member into the guide hole for making a support post for the tank; placing a ceiling member on the column member for forming a ceiling part; installing a wall member so as to surround the block on an outer periphery, thus forming a rainwater storage space; and wrapping the storage space with a sheet. A creep phenomenon of the resin block is not of a concern, because the column member ensures sufficient strength in the vertical direction.SELECTED DRAWING: Figure 1
【課題】樹脂製のブロックを配設した槽は槽の上部に存在する覆土の重量によりクリープ現象を起こし、長期使用の際十分な鉛直強度が保たれないおそれがある。その心配を解消する槽の鉛直強度を高める技術の提供にある。【解決手段】本発明は、地下に、上下に組立て可能でかつ垂直なガイド孔を有するブロックを槽の底部に配設し、前記ガイド孔に柱部材を挿入して槽の支柱とし、柱部材に天井部材を載置し天井部を形成し、外周辺のブロックを囲むように壁部材を配設して壁部を形成することで雨水等の貯留空間を形成し、当該貯留空間をシートで包んだ雨水等の貯留槽である。柱部材で鉛直強度を確保するため、樹脂製のブロックのクリープ現象を考慮する必要がない。【選択図】図1
