摘要
沉沙池是一种重要的泥沙处理工程设施,其作用是沉降含沙水流中有害粒径的泥沙。泥沙在沉沙池中沉降效果的好坏,与池内水流流场分布直接有关。为使沉沙池内水流流场分布更利于泥沙的沉降,对传统沉沙池进行了改进,在沉沙池工作段首部加设调流板来对入池水流进行调节,并用室内模型试验检验调节效果。对试验结果进行分析,表明经过调流板调节后的水流流场分布更利于泥沙在沉沙池内的沉降,可为工程设计提供参考。
Sediment basin is an important sediment processing faclity, it＇s function is to depositethe unprofitable sand in flow. The effection of sand＇s deposition is relation with the distribution of flow field in basin. In order to make the distribution of flow field good for sand＇s deposition, the traditional sediment basin has been improved by adding a adjusting flow board in forepart basin to adjust the flow entering sediment basin and the adjusting effection was verified by model experiment. Analyzing the results of experiment, it indicated that the adjusted distribution of flow field was better for sand＇s deposition in sediment basin, the improved measures can be used for project designing.
