摘要
排沙漏斗是高含沙河流水利工程中的重要泥沙处理工程手段,具有广泛的工程应用前景。在排沙漏斗设计中,在悬板非溢流区开孔可以获得更好的水沙分离性能。以某灌区渠首排沙漏斗为工程背景,探讨不同悬板开孔率对排沙漏斗工程效果的影响。结果表明,10%的悬板开孔率工程效果最佳,推荐在工程设计中选用。
Sand funnel is an important sediment treatment engineering means in water conservancy projects of high sediment laden rivers,which has a wide range of engineering application prospects.In the desilting funnel design,better water sediment separation performance can be obtained by opening holes in the non overflow area of the suspended plate.Taking the sediment discharge funnel at the head of an irrigation area as the engineering background,this paper discusses the influence of different opening rates of suspended plates on the engineering effect of sediment discharge funnel.The calculation results show that the 10%opening rate of the suspended plate has the best engineering effect,and it is recommended to be selected in the engineering design.
