摘要
沉沙池排沙廊道分流量直接影响沉沙池排沙用水的多少,对整个沉沙池工程影响重大,为此对分流量的计算问题进行了专门研究,并根据试验资料分析了水流强度、排沙廊道出口开度和溢流堰的高度等因素对分流量的影响规律,结合量纲分析建立了流量系数的半经验理论计算公式,通过实测值与计算值的误差比较表明,该流量系数计算公式形式简单、计算方便、精度较高,可供设计沉沙池工程时参考。
divergent flow of the flush gallery is the direct influence on desilting water of sand basin, and has serious influence on the whole of sand basin. Therefore the problem of divergent flow for the flush gallery has been researched specially,and the influence law,which is influenced by the flow intensity Fr,the opening of flush gallery and the height of spillway crest, has also been researched. The half experience theory formula of flow coefficient has been established by dimensional analysis. At last, the results of the actual value and the predicted value error indicate that the form of this formula is simple,the computation is convenient and the precision is high,which may supply reference for designing sand basin.
