Integrated Pump Station Cylinder Wall Function

1. The water pressure on the precast pump station cylinder wall is calculated based on static water pressure.

The corresponding design water levels for the standard water pressure values should be determined based on the data provided by the survey department and the hydrological department. For potential high and low water levels, a comprehensive consideration of changes over a period of time and the possible development trends during the engineering design reference period should be made.

The corresponding design water level for the standard value of water pressure should be determined based on the load effect on the structure, selecting either a high water level or a low water level. When a high water level is chosen, the corresponding value coefficient can be taken as the ratio of the average water level to the high water level; when a low water level is chosen, the corresponding standard value coefficient should be 1.0.
