[0002] Reservoir water intake pumping stations are usually built on the shore of the reservoir. Depending on their functions and the environment they are in, there are many problems, such as underwater construction, structural safety, and environmental protection. Depending on the construction relationship between the pumping station and the reservoir, the layout type adopted by the pumping station is also different. When the pumping station and the reservoir are built at the same time, the commonly used layout types are open channel water diversion and pressurized water diversion. However, at present, many water intake pumping stations draw water from built reservoirs, and the layout type of water intake buildings is greatly affected by topographic and geological conditions, reservoir water level changes, and water source environment. If the layout type of the water intake pumping station is not appropriate, it will cause problems such as increased investment, increased construction difficulty, or unchanged operation and management. This pump room layout type is suitable for water intake from built reservoirs, and has the advantages of saving investment, convenient equipment installation, and convenient operation and maintenance.
