- 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.
