根据排沙漏斗模型试验资料 ,通过对比分析排沙漏斗清、浑水流场特性 ,初步探明了排沙漏斗的水流结构和输沙机理。同时 ,排沙漏斗的原型观测和实际应用表明 ,排沙漏斗的实际工程应用是成功的 ,与曲线沉沙池和厢形沉沙池等传统工程措施相比 ,它具有截沙率高、排沙耗水量小、造价低等特点
According to the sand funnel model test data, the water flow structure and sediment transport mechanism of sediment funnel were preliminarily identified through comparative analysis of the characteristics of mudflow and muddy water flow field. At the same time, the prototype observation and practical application of sediment hopper showed that the practical engineering application of the sand funnel was successful. Compared with the traditional engineering measures such as curve settling tank and sand tank, it has the advantages of high sand cutting rate, Sand water consumption, low cost and so on
