一座岸边水下泵站的设计布置

阐述了一座岸边水下泵站设计布置,它是根据黄河北干流山谷河段水位变幅大,以及站址地形条件而设计的。在高水位运行时段和洪水期,主厂房全部淹于水下;副厂房布置在高于校核洪水位的塔井内,塔井兼作交通井,充分利用了厂房空间,解决了水位变幅大的岸边泵站取水问题。为了缩小在黄河中构筑围堰的规模,将前池布置在厂房的一侧,进水闸轴线与前池内圆周接近相切,形成池内环流,防止泥沙淤积。文中创意可供类似工程设计参考。

Design and Layout of an Underwater Bank Pumping Station

This text expatiates the design and layout of an underwater bank pumping station which was designed according to the large variation of water level of valley reach of north main stream in Yellow River and the terrain conditions of the station site. During the running period of high water level and flood period, the main power house is all submerged in water; auxiliary powerhouse was arranged in a tower well which was higher than the check flood level. As an access well the tower well made full use of the space of the power house and the problem of water intake of bank pumping station under the condition of the large variation of water level was solved. In order to shrink the size of the cofferdam in the Yellow River, the forebay was built on one side of the power house, the axis of the intake sluice was nearly tangent to the inner circumference of the forebay and circulating flow in the bay was formed to prevent the sediment deposition. The innovation of the article can be used for engineering design references.
