[0070] Such as Figure 6 As shown, a pumping station hub adopts the arrangement of gates and stations side by side. 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 pumping station 2 has a length of 24.5m along the flow direction and a width of 38.9m in the vertical flow direction. The angle β between the centerline 9 of the pumping station and the centerline 10 of the diversion river is 10°. The control gate 1 of the pump 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 of the vertical water flow direction is 53.6m. According to the needs of the structure layout of the cleaning machine bridge, the length and width of the pier 12 of the cleaning machine bridge in the original design are 10m and 1m respectively.
[0071] The pier 12 of the cleaning machine bridge orig...
