导流装置的变化对自排沙廊道排沙效果的影响

The Influence of Change of Deflector Installation on Desilting Effect of Auto-desilting Gallery

通过对自排沙廊道进行浑水模型试验,分析了廊道上部排沙导流装置参数的变化对排沙耗水率及廊道出口含沙量的影响。试验得出排沙耗水率随着孔数增加而增大,与重量比含沙量变化成反比。而随着偏转角的增加,相应耗水率减小较大。

According to the turbid-water model experiments of the auto-desilting gallery,the influences of deflector installation on water consumption rate and sediment concentration are analyzed in this paper.The experiment makes a conclusion that water consumption rate will increase with the increase of the diameter,the sediment concentration will decrease on contrary.And with the increase of the installation angle of desilting bore,the water consumption rate will quickly decrease.
