GATE DEVICE AND GATE RESTING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a new gate device for resting a gate in a midway position such as a discharge channel shaft.SOLUTION: A gate device for opening-closing a water passage comprises a gate liftably suspended by an opening-closing wire rope and opening-closing the water passage by lifting operation, a hoisting device installed above the gate, lifting the gate by hoisting the opening-closing wire rope and lowering the gate by lowering, a resting wire rope having one end fixed to the gate and extending upward on the other end side by standing up from one end in the length shorter than the length between the lowest position of the gate being a position for closing the water passage and the highest position of the gate being direct under an installation position of the hoisting device, holding means for holding the resting wire rope in a standing-up state, and a connector installed in the vicinity of the installation position of the hoisting device and detachably connected to the other end of the resting wire rope of arriving up to a height in the vicinity of the installation position of the hoisting device in response to a rise of the gate.SELECTED DRAWING: Figure 1
【課題】ゲートを放水路立坑等の途中位置で休止させる新規なゲート装置を提供する。【解決手段】水路を開閉するゲート装置は、昇降可能に開閉用ワイヤロープに吊られ、昇降動作により水路の開閉を行うゲートと、ゲートの上方に設置され、開閉用ワイヤロープを巻き上げてゲートを上昇させ、巻き下げることでゲートを下降させる巻上装置と、一端がゲートに固定され、水路を閉じた位置であるゲートの最低位置と巻上装置の設置位置直下であるゲートの最高位置との間の長さよりも短い長さで、一端から立ち上がって他端側が上方に延びる休止用ワイヤロープと、休止用ワイヤロープを立ち上がった状態に保持する保持手段と、巻上装置の設置位置近傍に設置され、ゲートの上昇に伴って巻上装置の設置位置近傍の高さにまで到達した休止用ワイヤロープの他端と脱着可能に連結する連結具とを備える。【選択図】図１
