新疆金沟河排沙工程涡管排沙技术的应用

Application of Sediment Release by Vortex Tube to the Sediment Release Project of Jingou River in Xinjiang

根据金沟河涡管排沙工程的布置形式及排沙要求,提出了排沙涡管开口宽度、涡管直径、涡管与渠道轴线夹角、涡管开口长度、涡管纵向坡度等技术指标的确定方法,计算并分析了排沙涡管截沙率及排沙效果。结果表明:通过对排沙涡管进行改进,金沟河排沙平均耗水量占引进水量的4.51%,符合原设计的技术指标。

According to the Jingouhe River basin sediment release by the vortex tube arrangement form of engineering and effective demand,it put forward the open width of vortex tube,sediment vortex tube diameter,the vortex tube and channel axis Angle and the vortex tube length,opening the vortex tube and technical indexes of vertical gradient method for the calculation and analysis of the vortex tube sand and effective in desilting rate effect.Through to the vortex tube sand improved,Jingouhe River basin water consumption accounts for an average ditch introduction of water by 4.51%,being in line with the original design technology indicators.
