The flood drainage integrated precast pump station is mainly composed of glass fiber reinforced plastic cylinder, sewage lifting pump, crushing grate, intelligent control system, operation platform, and related accessories such as manhole covers.

‍The first parameter to determine for an integrated precast pumping station for flood drainage is the flow rate of the station, which is determined based on the wastewater volume to be treated. Once the flow rate is established, we select the appropriate pump set based on the flow rate, typically using three to four wastewater lift pumps (including backup pumps). The selection of the pump is based on flow rate and head.

Each rainy season, flood control and drainage become a top priority for the department. Certain areas, with low-lying terrain and pipelines that lack powered waste water transportation, are particularly prone to flooding, which can淹没 roads and residential areas. In extreme cases, wastewater backflow can occur, causing inconvenience to residents and economic losses. With the implementation of disaster prevention and reduction projects, the construction of sluice gates, embankments, and drainage pump stations has enhanced the city's flood control and drainage capabilities.
2. In traditional drainage pump stations, the drainage pumps cannot filter out sediments and stones from the water during the pumping of rain and wastewater, which increases the viscosity of the fluid, thereby reducing the lift height of the pump and increasing energy consumption. Additionally, sediments and debris in the water can cause blockages in pipes and damage to the pump impeller, thereby shortening the lifespan of the drainage pump.
3. Regarding the aforementioned technology, the inventor believes that traditional drainage pumps cannot filter out silt and stones from rainwater, which would increase the energy consumption of the entire drainage station.

(1) Excavation of the foundation pit is carried out using machinery, with manual assistance for cleaning. The soil is transported in conjunction with excavators and dump trucks, being transported externally to the soil stacking area. To ensure the safety of soil excavation and prevent collapses, the foundation pit is graded at a 1:0.67 slope. The layout and leveling work is closely coordinated with manual soil excavation. Special attention must be paid to controlling the elevation of the pool bottom during construction. It is mandatory to leave a 20cm buffer of soil, which will be cleared manually. It is strictly prohibited to dig, disturb, or damage the original soil condition, as this may affect load-bearing capacity.
