According to the requirement of engineering construction and in order to comprehensively test the rationality of engineering general arrangement and arrangement of architectural structure,the paper carried out the experiments of water division, flood discharge and scouring to some headwork. The results have shown that the flood discharge and over current ability of hub can meet the requirements under different inflows and intakes, the effect of energy dissipation and sour prevention of river sluice is favorable and the general and architectural structure arrangement of the engineering are reasonable. Meanwhile, it also optimized sand prevention and discharge arrangement of hub and presented the best operation mode of gate.
