The joint construction of sluice stations in the coastal plain area is widely used, but due to the complex inflow conditions, it is easy to produce reflux, vortex and other undesirable flow patterns, which have extremely adverse effects on the operation of pumping station units. For a sluice station project into the flow pattern problem, the model test to optimize the flow pattern of the front pool of the pumping station, the pumping station forebay with additional flow isolation pier program. The study found that: rectification scheme, pumping station before the pool flow pattern has a more obvious improvement, 1#, 2# inlet flow uniformity distribution increased by 9% and 2%. There will be no obvious adverse effects on the inflow conditions of the sluice. The optimized scheme has better inlet flow conditions than the original scheme, and the proposed optimized scheme can provide reference experience for other similar projects.
