3、。进水流道能够为水泵提供良好的进水条件。双向流道布置具有占地面积小、节省工程投资、便于集中管理等优点。本设计泵站以灌溉为主，兼有挡洪、排涝任务，属中型泵站，选用块基型结构的泵房，即进水流道与泵房底板整体浇筑，形成一块状基础结构作为整个泵房的基础。本设计采用正向进水前池，前池的水流方向和与进水池的水流方向一致，水流的流态平顺，池的结构简单、施工方便。本设计采用双向进出水流道，以满足泵站自引、自排及双向提水的要求。进水流道能够使水流从前池进入水泵叶轮室的过程中更好地转向和加速，为水泵提供良好的进水条件。双向流道布置具有占地面积小、节省工程投资、便于集中管理等优点；缺点是对进水流道设计要求较高，否则
4、，容易增加阻力损失，进水流道易产生涡带，导致水泵及站房振动，严重时可能危及机组和站身安全。本设计将检修间和配电间分别布置在泵房的两端。在泵站排涝期间，为防止水草等杂物进入进水流道，在内河侧设置清污机，以保证泵站的有效运行。清污机具有自动化程度高、工作效率高等优点。 关键词: 泵站 灌溉AbstractSome cities intend to dismantle the old station of soil bridge , one Xin Jian pump station , are 22 m3/s blocking flood , irrigation , draining water
