The invention discloses a submersible type lift pump
station. The submersible type lift pump
station comprises a pump room, the pump room is internally provided with an inflow
sediment buffering area and a
sediment deposition and water pump absorption area. The
sediment deposition and water pump absorption area is internally provided with multiple pump pits at intervals in the direction parallel to the water running direction, and the multiple pump pits are each internally provided with a submersible
sewage pump; water outlet pipes of the submersible
sewage pumps are each provided with a sediment reverse rinsing
pipe, and water outlet ends of the sediment reverse rinsing pipes extend into the pump pits; the water outlet ends of the sediment reverse rinsing pipes are arranged to be a U-shaped or annular
pipe heads, the sediment reverse rinsing pipes are arranged surrounding submersible pumps and along the walls of the pump pits, and each U-shaped or annular
pipe head is provided with multiple holes in the pipe body direction. The submersible type lift pump
station is particularly applicable to a high-water-level-change sediment-laden river in a hilly region, water lift work can be successfully conducted in flood reasons, and the phenomena of sediment accumulation and damage of submersible
sewage pumps in the pump room cannot be caused. The construction difficulty and
engineering investment cost of lift pump station of the high-water-level-change sediment-laden river in the hilly region are further drastically reduced.
