摘要:
基于物理模型试验方法，对某城镇分流制强排系统雨水泵站进水流道的水力特性进行研究，并提出了改善不良流态及消除有害漩涡的整流方案。结果表明，原设计方案进水流道内有大面积回流和漩涡，可能会影响水泵的正常运行；采用不同的整流措施进行优化发现，布设单一消力墩、防涡梁这两类整流措施优化效果有局限性，消力墩+防涡梁组合式整流措施能对进水流道内的不良流态进行全面改善，有效防止漩涡和吸入空气等现象发生。
Abstract:
Based on the physical model test method, the hydraulic characteristics of the inlet channel of a stormwater pumping station in an urban diversion and forced drainage system were investigated, and a rectification scheme to improve the undesirable flow pattern and eliminate the harmful vortex was proposed. The results showed that, in the original design, there was a large area of backflow and vortex in the inlet channel, which might affect the normal operation of the pump. Different optimized rectification measures indicated that the two kinds of rectification measures (single stilling pier and anti-vortex beam) had limitations in the optimization. The combined rectification measure of stilling pier and anti-vortex beam improved the undesirable flow pattern in the inlet channel and effectively prevented the occurrence of vortex and air intake.
