The relationship between the diversion pier and inlet and outlet hydraulic performance of two-way water flow side inlet and outlet was studied. Through the hydraulic model test and comparison, the shape and arrangement of the branch pier were studied on the flow and velocity distribution and the head loss coefficient Aiming at the characteristics that the water level of the pumped storage power station changes greatly and the water flow direction is opposite at the power generation and pumping conditions, a number of experimental schemes have been drawn up, and different schemes of water flow at high water level and low water level Direction of the hydraulic performance of the experimental comparison.The study shows that the shape and location of the diversion pier and the two-way flow side of the water inlet and outlet hydraulic properties are closely related
