SIPHON DRAINAGE FACILITY
To provide a practical siphon drainage facility easy to use a large-bore siphon drain.SOLUTION: A drain pipeline is water-sealed by setting the discharge end C of a siphon drain pipe 11 higher than a draining pipe bore and opened, a pipe line part water-sealing with residual water is provided to the drain pipe 11 upstream the discharge end C to discharge, the discharge pipe line is water-sealed by connecting a gas/water discharge pipe end 51B of an ejector 51 air-intaking by a water jet provided outside the pipeline to the drain pipe 11 and passing. Inner water in the same water suction range 2 as the siphon drain pipe 11 is supplied to the siphon piping 11 as driving water of the ejector 51 and used, and water of an outer water source is pressurised and used, an air intake port of the ejector 51 is continued to the vicinity of a head part of the siphon drain pipe 11 and water is sucked by evacuating the siphon drain pipe 11 to actuate a siphon drainage facility. An amount of injection water of the ejector driving water is small, and a small diameter pipe manually handled is enough.SELECTED DRAWING: Figure 1
【課題】大口径サイフォン排水を使用しやすくする実用的なサイフォン排水設備を提供する。【解決手段】サイフォン排水管１１の吐出端Ｃを該排水管口径よりも高くして開口させ、該吐出端Ｃ上流の排水管１１に滞留水で封水する管路部分を設けて吐出させ、該管路外に併設した水噴射で吸気するエジェクター５１の気水排出管端５１Ｂを排水管１１に接続流入させて該排水管路を封水し、エジェクター５１の駆動水に、サイフォン排水管１１と同一吸水域２内水をサイフォン配管１１して給水して使用することや、外部水源水を加圧して使用し、該エジェクター５１の吸気口をサイフォン排水管１１の頭頂付近に接続連通して該サイフォン排水管１１内を抽気し呼び水して、サイフォン排水設備を稼働させる。エジェクター駆動水の呼び水は、注水量も少なく、人力で取り扱いできる程度の小径で容易である。【選択図】図１
