DUST COLLECTING DEVICE IN INTAKE CHANNEL
PROBLEM TO BE SOLVED: To effectively inhibit and reduce dust including drift wood flowing into an intake port, without causing increase in the size of the facility scale, trouble according to installation work and cost, and without having an adverse effect on a river environment.SOLUTION: A dust capturing device which is moored in a state of floating on an intake channel 62 for guiding storage water of a dam lake to an intake port and which captures dust that is flowing down includes: a pipe body 3 including an opening 5 for receiving the dust flowing down the intake channel to the inside; discharge means 20 for connectedly provided at one end of the pipe body and for discharging the flowing water which has flowed into the pipe body to the outside together with the dust; and dust capturing means 30 for capturing the dust discharged from the discharge means together with the flowing water, and for discharging only the flowing water to the downstream side.SELECTED DRAWING: Figure 2
【課題】設備規模の大型化、設置工事に伴う手数や費用の増大を招くこと無く、また河川環境に悪影響を与えることなく、流木を含む塵芥が取水口に流入することを効率的に阻止、低減する。【解決手段】ダム湖の貯留水を取水口へ導く取水路６２に浮いた状態で係留され、流下してくる塵芥を捕捉する塵芥捕捉装置であって、取水路を流下してくる塵芥を内部に受け容れる開口部５を備えた管体３と、管体の一端に連設されて管体内に流入した流水を塵芥と共に外部へ排出する排出手段２０と、該排出手段から流水と共に排出されてきた塵芥を捕捉して流水のみを下流に放出する塵芥捕捉手段３０と、を備える。【選択図】図２
