沉沙池水力特性的研究

Study of Hydraulic Characteristics on Sediment Basin

[目的]为了使水流流场更加均匀,泥沙在沉沙池中的沉淀效率更高。[方法]改进沉沙池工作段的水流流场,即在沉沙池首部加设调流板。[结果]通过室内模型试验,检验了调流板调节水流流场的调节效果。[结论]调流板不仅能提高泥沙的沉淀效率,而且能缩短沉沙池过渡段的距离。

[Objective] The research aimed to make the flow field more uniform,and sediment precipitation in sediment basin have a higher efficiency.[Method] The flowfield of the work section of sediment basin was improved,which was adding adjusting flow board.[Result] The basins were verified by model test plate adjustment to study the flow field adjustment effect.[Conclusion] Adjusting flow board not only could improve the deposition efficiency of sediment basins board,but also shorten the distance setting basin in the transitional period.
