DRAINAGE PUMPING STATION
To provide a drainage pumping station that does not require a large installation area and can deposit sand contained in inflow water in a predetermined place with a simple configuration.SOLUTION: The drainage pumping station comprises: an inflow channel 1 that is connected to a trunk water channel 101; a plurality of pump suction channels 3 that are connected to the inflow channel 1 and are arranged adjacent to each other; a plurality of suction water tanks 5 that are connected to the respective pump suction channels 3; and a plurality of pumps 7 that discharge the inflow water in the respective suction water tanks 5. The inflow channel 1 is arranged outside the plurality of pump suction channels 3 so as to surround a part of the plurality of pump suction channels 3. Further, the inflow channel 1 has at least one deceleration part 25 that reduces a flow velocity of the inflow water to the flow velocity at which the sand contained in the inflow water can settle.SELECTED DRAWING: Figure 1
【課題】広大な設置面積を不要とし、かつ簡易な構成で、流入水に含まれる砂を所定の場所に堆積させることが可能な排水機場を提供する。【解決手段】排水機場は、幹線水路１０１に接続される流入水路１と、流入水路１に接続され、互いに隣接して配置された複数のポンプ吸込水路３と、各ポンプ吸込水路３に接続された複数の吸込水槽５と、各吸込水槽５内の流入水を排出する複数のポンプ７と、を備える。流入水路１は、複数のポンプ吸込水路３の一部を取り囲むように、該複数のポンプ吸込水路３の外側に配置されている。さらに、流入水路１は、流入水の流速を該流入水に含まれる砂が沈降可能流速まで低下させる少なくとも１つの減速部２５を有している。【選択図】図１
