DRAINAGE PUMPING STATION AND DRAINAGE METHOD
PROBLEM TO BE SOLVED: To provide a drainage pumping station capable of being downsized while securing safety, and a drainage method.SOLUTION: A drainage pumping station (100) is provided that comprises: a suction water tank (2) which is the suction water tank (2) in which water from an inflow channel (1) flows in, and which is wider than an inflow channel (1) and deeper than the inflow channel (1); a pump suction channel (3) which is the pump suction channel (3) in which the water from the suction water tank (2) flows in, and which is shallower than the suction water tank (2); partition walls (31a-31d) arranged in the pump suction channel (3)and forming a plurality of channels (61-64); pumps (32a-32d) arranged in the plurality of channels (61-64) respectively and draining the water in each of the channels (61-64); and a wall (21) which is in the suction water tank (2) and extends substantially orthogonal to the water flow, whose lower end is at a position lower than the bottom of the inflow channel (1), but which does not come into contact with the bottom of the suction water tank (2).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）からの水が流れ込む吸込水槽（２）であって、前記流入水路（１）より幅広であり、かつ、前記流入水路（１）より深い、吸込水槽（２）と、前記吸込水槽（２）からの水が流れ込むポンプ吸込水路（３）であって、前記吸込水槽（２）より浅い、ポンプ吸込水路（３）と、前記ポンプ吸込水路（３）に配置されて複数の水路（６１〜６４）を形成する隔壁（３１ａ〜３１ｄ）と、前記複数の水路（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（３１ａ〜３１ｄ）と、前記吸込水槽（２）内にあって水の流れと略直交して延びており、下端が前記流入水路（１）の底より低い位置にあるが、前記吸込水槽（２）の底には接しない壁（２１）と、を備える排水機場（１００）が提供される。【選択図】図１
