中文摘要

某市拟拆除土桥旧站,新建一座抽水站,作为江堤达标建设的附属配套工程,兼挡洪、灌溉、排涝于一体,设计流量22m3/s。该站的主要任务是与十二圩泵站联合运行,抽引江水,补给淮水水源的不足,解决该市境内13个乡近50万耕地的灌溉用水,并结合仪扬河以南圩区64平方公里面积的排涝任务,要求在上下游水位组合允许时,能实现自流和自排,保证该地区社会与经济的可持续发展。

本设计泵站以灌溉为主,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。

考虑泵站的多重任务,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,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

Abstract

Some cities intend to dismantle the old station of soil bridge , one Xin Jian pump station , are 22 m3/s blocking flood , irrigation , draining waterlogged farmland in an integral whole , designing rate of flow concurrently as the affiliation auxiliary projects that the river dike builds up to the standard. Be the major task standing's turn to be to unite with twelve country fair pump stations working , to shrink to attract river water, deficiency replenishing Huaihe River water with a source of water, almost 500,000 13 countryside cultivated land irrigation resolving that city within the territory uses water , join draining waterlogged farmland spreading River 64 square kilometers to the south country fair area area combining with an instrument the mission, can realize the sustainable development flowing by itself and swear to owe area society and economy from the row when requiring that water level combination allows in upper lower reaches,. Originally, design that the pump station gives first place to irrigation , belong to the medium-sized pump station , select and use a piece Consider multiple pump station mission , design is adopted two-way pass in and out of streams saying that self quotes from a row in order to satisfying a pump station ,and two-way request carrying water. Enter streams being able to be that the water pump provides fine water-entering condition. Two-way runner arrangement has Zhan field area merit such as small , economizing project investment , centralized management easy to. Design that the pump station gives first place to irrigation originally , simultaneously, have

blocking flood , drain waterlogged farmland the mission, belongs to the medium-sized pump station ,

select and use a piece base the architectural pump house of type, is that streams says and the pump house bottom board entirety concrete move forward , the form of block infrastructure forming

one is entire pump house basis. Capital is designed adopt water-entering forward direction front

pool, front pool streams direction and the streams direction with entering pool are consistent, the

streams stream state smooth-going, the pool structure is simple , construction is convenient
