[0070] like Image 6 As shown in the figure, a pumping station hub adopts a parallel arrangement of gates and stations. The pumping station 2 of the pumping station hub is equipped with 5 sets of vertical axial flow pump units, and the diameter of the pump impeller is D. 0 The length of the pumping station 2 is 24.5m in the downstream direction, the width in the vertical direction is 38.9m, and the angle between the centerline 9 of the pumping station and the centerline 10 of the diversion river is β=10°. The control gate 1 of the pumping station hub is divided into 5 holes, each hole has a net width of 10m, the length of the gate body along the water flow direction is 24.5m, and the width in the vertical water flow direction is 53.6m. According to the needs of the structural arrangement of the cleaning machine bridge, the length and width of the pier 12 of the originally designed cleaning machine bridge are 10m and 1m respectively.
[0071] The pier 12 of the cleaning machin...
