TEMPORARY COFFERING FACILITY FOR REPAIRING FLOOD SPILLWAY GATE OF DAM BODY
PROBLEM TO BE SOLVED: To provide a temporary coffering facility for repairing a flood spillway gate of a dam body that satisfactorily performs damming-up function at a time of normal water level, conducts water safely and securely at a time of flood, and offers high workability and economic efficiency.SOLUTION: A temporary coffering facility 25 is for reforming a flood spillway gate of a dam body 30. A damming-up mechanism comprises a rotatable door body 5 supported by a flexible hinge sheet 7 on a top surface of a foundation base 38, and flexible bag bodies 12 (A,B) installed on a downstream side of the door body 5. A flap gate 3 is configured such that when the bag bodies 12 (A,B) expand, a top part of the door body 5 is rotated to an erected position U at a height almost equivalent to a top part of a flood spillway gate 31, and when the bag bodies 12 (A,B) contract, a front surface of the door body 5 is rotated to a falling position D at a height almost equivalent to a bottom part of the flood spillway gate 31.SELECTED DRAWING: Figure 2
【課題】平水量時には堰止め機能を確実に発揮し、洪水時には安全かつ確実に通水させる機能を発揮し、施工性や経済性に優れたダム堤体の洪水吐ゲート改修用仮締め切り設備を提供する。【解決手段】ダム堤体３０の洪水吐ゲート改修用仮締め切り設備２５である。堰止め機構は、基礎台３８の上面に可撓性のヒンジシート７で支持された回動可能な扉体５と、扉体５の下流側に設置された可撓性の袋体１２（Ａ，Ｂ）とで構成されている。袋体１２（Ａ，Ｂ）の膨張で、扉体５の上部が洪水吐ゲート３１の上部に略相当する高さの起立位置Ｕに回動されるとともに、袋体１２（Ａ，Ｂ）の収縮で、扉体５の前面部が洪水吐ゲート３１の下部に略相当する高さの倒伏位置Ｄに回動されるようになった起伏ゲート３である。【選択図】図２
