摘　　要：结合某内河港口工程,对取水泵房工艺设计中的若干难点进行研究。为减少进水管泥沙淤积,在进水管流速取值问题上引入了泥沙不淤流速计算公式;针对现行的《室外给水设计标准》对位于码头前沿取水泵房设计高程规定不明确的问题,通过对比分析相关规范,给出确定原则。结果表明,在进水管较短、水利损失较小的前提下可参照泥沙不淤流速计算公式适当提高进水管流速;入口地坪处设计高水位可在不低于港口防洪水位的基础上,结合泵站分级综合确定;浪高可参照基本不越浪的直立堤堤顶高程确定。By investigating a certain inland river port project,this paper studies several difficulties in the technological design of water intake pump houses.To reduce the sediment deposition in the inlet pipe,this paper adopts the calculation formula for the non-deposition flow velocity of sediment to determine the flow velocity in the inlet pipe.Considering that the current Standard for Design of Outdoor Water Supply Engineering fails to specify the design elevation of a water intake pump house located at the front of a wharf,this study carries out a comparative analysis of the relevant codes and presents a determination principle.The results show that when the inlet pipe is short and the hydraulic loss is small,the personnel concerned can increase the flow velocity in the inlet pipe to a proper extent according to the calculation formula for the non-deposition flow velocity of sediment.They can determine the design high water level at the entrance floor comprehensively in accordance with the classification of the pumping station on the premise that it is not lower than the flood control level of the port.They can also obtain wave height by referring to the top elevation of vertical breakwaters rarely subject to overtopping.
