Description
サイホン管端に上昇水路部分を設けた放流管を経て放流することは、管端のシール性を確保して、確実にサイホン効果を得られることは勿論であるが、通水開始時の排気時間の短縮、吸水口の吸水状況変化時の放流端の安定を保ち、更に、サイホン管端を溜め桝内に開放す場合のような沈殿物の堆積や、放流口に逆止弁を設ける場合のような木枝異物の詰り、引っ掛かりがない。
Be discharged through a discharge pipe provided on the rising water passage portion siphon tube end, to ensure the sealing of the tube end, certainly it obtained the siphon effect is, of course, exhaust water passing through the start To reduce the time, maintain the stability of the discharge end when the water intake status of the intake port changes, and deposit sediments such as when opening the siphon tube end into the reservoir and installing a check valve at the discharge port There is no clogging or catching of foreign matter like tree branches.
尚、長期間堆積した沈殿物jは吸引され難いため、補吸水管4Dの下方端に下方、或いは前方に向けたノズルを配設して、別途用意した圧力水をフラッシングする。
また、この圧力水をフラッシングする方法は、他の実施例の場合にも必要に応じて採用できるが、通常はダム湖堰堤近くの沈殿物は、軽質微細な物であり備える必要はない。
In addition, since the deposit j accumulated for a long period of time is difficult to be sucked, a nozzle directed downward or forward is disposed at the lower end of the auxiliary water suction pipe 4D, and separately prepared pressure water is flushed.
Further, the method of flushing the pressure water can be adopted as needed in the case of other embodiments, but usually, the sediment near the dam lake dam is light and fine and does not need to be provided.
Claims (6)
At the end of the pipe that pumps and drains using siphon pipes and the pipe over the mountain of the pump (middle and high pipes), the pipe that discharges downwards is provided with an upward pipe at the end of the pipe the reservoir with a freely water in the tube body between portions of dissipating flow tube end is provided, punched on the bottom tube upper edge of the upward turning part, or a slit-shaped hole opens toward the downstream riser section An outlet device for siphon piping that is constricted and communicates between the reservoir and the pipe.
