本文提出了分流槽中侧向堰孔装置(隔板堰)的流动分析方法。为了便于分析,只考虑单个侧堰孔组合装置。运用现有的二元水槽侧向分流的水力模型求得矩形侧堰孔装置的出流量.文中对一定进流量下如何设计相应的侧堰孔装置作了讨论。结果表明,只要恰当地设计侧堰孔装置,就能在一定上游水深范围内保证所希望的出流量与主槽流量为某一比值。试验槽中所取得的实测资料证实了堰孔出流的几何要素与水力要素之间的理论关系.对于宽度一直加大到与主槽等宽的侧堰孔装置的出流,该预测的关系式都是正确的.
This paper presents a method for the flow analysis of lateral weir devices (spacer weir) in a shunt tank. For ease of analysis, only a single side weir assembly is considered. The outflow of the rectangular side weir hole device is obtained by using the existing hydraulic model of lateral diversion of the binary sink.This paper discusses how to design the corresponding side weir hole device at a certain inflow rate. The results show that as long as the side weir hole device is properly designed, it is possible to ensure a desired ratio of the outflow to the main tank flow within a certain upstream water depth. The measured data obtained in the test tank confirms the theoretical relationship between the geometrical elements of the outflow from the weir hole and the hydraulic elements.For the outflow of the weir hole device whose width has been increased to be equal to that of the main groove, the predicted relationship The style is correct.
