CONSTRUCTION STRUCTURE OF SEAWATER INTAKE POWER GENERATION FACILITY WITH FLOW SUPPRESSIVE COVERED CONDUIT CONSTRUCTION
PROBLEM TO BE SOLVED: To provide a construction structure of a flow suppressive covered conduit capable of ensuring safety even if a big wave during typhoon and a large heave of tidal wave are narrowed into the suppressive covered conduit.SOLUTION: A construction structure can cope with a heave and a wave force by placing thick steel pipes horizontally to a levee crown at a levee crown part of a suppressive covered conduit, filling concrete in the steel pipes, connecting a head part of a large-diameter type II port erection steel pipe in portal shape and the horizontal thick steel pipe by bolting and electric welding, applying reinforced-concrete jacketing to the connected part to be a floor panel with corner, stacking a mound aggregate on the floor panel to be unified on which 2,5 m deep reinforced-concrete panel is casted, in order to respond to a destructive force applied from the inside of the suppressive covered conduit to the outside when heaving seawater is narrowed into the suppressive covered conduit. In order to respond to ejecting seawater at a drain port part, an open channel width is widened and a height of an upper part of the drain port is increased to widen the drain port width, and drop-based power generating turbine is overhung to become freely slidable.
【課題】台風時の大波、津波時の大きいうねりを抑制型暗渠水路に絞り込んでも安全性が確保できる抑制型暗渠水路の構築構造を提供する。【解決手段】抑制型暗渠排水路へうねり海洋水を絞り込む際の抑制型暗渠水路内部から外側へかかる破壊力に対し、抑制型暗渠水路の天端部は肉厚鋼管を天端に水平に並べ、その鋼管内部にはコンクリートを詰め込み、更に、門型形状立て込み大口径２型港湾鋼管頭部と水平肉厚鋼管部はボルト締め、電気溶接で連結し、その部分は鉄筋コンクリート巻きのコーナー付き床盤とし、その上にマウンド骨材を積み重ねて一体化し、更にその上に鉄筋コンクリートの床盤を２，５ｍ打ち、うねり、波力に対応出来る構築構造にした。又、排水口部の海洋水の突出に対しては開水型水路幅を拡張し排水口上部の高さを大きくとり、排水口幅を広げ、落差発電タービンを張り出し、スライドが自在に出来る構造とした。【選択図】図１
