DRAIN PUMP STATION AND DRAINAGE METHOD
PROBLEM TO BE SOLVED: To provide a drain pump station, which can be downsized while ensuring safety, and a drainage method.SOLUTION: A drain pump station (100) comprises: an inflow channel (1); a suction sump (2) into which water discharged from the inflow channel (1) flows and which is connected to an outlet of the inflow channel and wider in width than the inflow channel; a pump suction channel (3) into which water flows from the suction sump (2); barriers (31a-31d), which are disposed in the pump suction channel (3) and form multiple channels (61-64); pumps (32a-32d), which are disposed respective channels (61-64) and discharge water in the channels (61-64); a cutoff wall (21), which is an end part of the suction sump (2) and extends in a direction perpendicular to a water flow direction at the outlet of the inflow channel (1). An inlet of the pump suction channel (3) and an outlet of the inflow channel (1) are formed on the same side of the cutoff wall (21).SELECTED DRAWING: Figure 1
【課題】安全性を確保しつつ、小型化が可能な排水機場および排水方法を提供する。【解決手段】流入水路（１）と、流入水路（１）から排出された水が流れ込む吸込水槽（２）であって、流入水路の出口と接続され、流入水路より幅広である、吸込水槽（２）と、吸込水槽（２）からの水が流れ込むポンプ吸込水路（３）と、ポンプ吸込水路（３）に配置されて複数の水路（６１〜６４）を形成する隔壁（３１ａ〜３１ｄ）と、複数の水路（６１〜６４）のそれぞれに配置され、各水路（６１〜６４）内の水を排水するポンプ（３２ａ〜３２ｄ）と、吸込水槽（２）の端部をなし、流入水路（１）の出口における水の流線方向と交差する方向に延びる止水壁（２１）と、を備え、ポンプ吸込水路（３）の入口と、流入水路（１）の出口とが、止水壁（２１）に対して同じ側に設けられている、排水機場（１００）が提供される。【選択図】図１
