LAND-TYPE FLOATING BODY-TYPE FLAP GATE
PROBLEM TO BE SOLVED: To mitigate a load on a wire rope connecting tips of door bodies.SOLUTION: A land-type floating body-type flap gate 11 includes a plurality of continuously installed door bodies 2 supported on a rear edge side and has a tip side that rises and swings. A wire rope 3 has one end fitted on a rear edge part of each of the door bodies 2, and a weight 5 fitted on the other end. Stationary pulleys 4a, 4b are disposed on the rear edge side of each of the door bodies 2 for guiding the wire rope 3, such that the weight 5 reaches the lowermost position midway while each of the door bodies 2 is rising or falling, thereby assisting rising or falling when rising or falling starts, at the same time functioning as a resistance against rising or falling before completion of rising or falling. Of the stationary pulleys 4a, 4b disposed on the rear edge side of each of the door bodies, height position of the stationary pulley 4a disposed adjacent to the rear edge part of the door body is made variable.EFFECT: A load on the wire rope that connects tips of the door bodies is mitigated, in view of influences of sliding resistance at a door stop on a side part and a difference in rising time when a tsunami strikes.SELECTED DRAWING: Figure 3
【課題】扉体の先端を連結するワイヤロープへの負荷を低減する。【解決手段】後端側を支点として先端側が起立搖動する複数の連続配置した扉体２を有する陸上型浮体式フラップゲート１１である。それぞれの扉体２の後端部に一端を取付けたワイヤロープ３の他端にウエイト５を取付ける。それぞれの扉体２が起立又は倒伏の途中でウエイト５が最下限位置となり、起立又は倒伏の開始時には起立又は倒伏を補助する一方、起立又は倒伏の完了前には起立又は倒伏の抵抗として作用するよう、それぞれの扉体２の後端側にワイヤロープ３を案内する固定滑車４ａ，４ｂを配置する。それぞれの扉体の後端側に配置した固定滑車４ａ，４ｂのうち、扉体の後端部と隣接する位置に配置した固定滑車４ａの高さ位置を変更可能に構成する。【効果】側部戸当りとの摺動抵抗の影響や、津波作用時の起立時間差に対応して、扉体の先端を連結するワイヤロープへの負荷を低減できる。【選択図】図３
