In the plain region, The plain landform has lead to the longer distance between the river and the starting of the storm sewer canal and the larger the buried depth. that may increase the difficulty of construction, and the water level of the rainwater drained export pipe canal lower than the flood level. Or affected by the sea tide，We have to build the rainwater pumping. The rainwater pumping station is a pumping station setting in the rain in the pipeline system or city lowlands, in order to ruled out the city’s rainwater, and can use for prevent ponding and delivery water. The rainwater of downtown always be rule out by the pump because of the higher water level in the plain city like Shanghai. The rainwater pumping station shoulder the visual task of sewerage and prevent flood as the major institution of municipal construction and Management engineering. And the design of the pumping station will be complex, that may increase the scale of invest. The waste will unable to remedy if the design is irrational. So, select the pump station type reasonable, ascertain pump station size, design the water pump station process correctly will has vital significance for ensuring the equipment operated safety efficient and reducing the operating cost, saving power consumption and reducing project cost.
The process design for rain water pumping station is mainly according to the actual condition of Shanghai, aiming at meeting the located design acquirement of rain water pumping station. Data collection, calculation, drawings are include in the design. Above all，I should collect the rain situation of Shanghai region, and know about the service condition of rain water pumping station that already built or are being built. Analysing the case that already done. Then confirm the scale of pumping station can be sure according to the design and the actual situation. And do the overall process arrangement, the water pump’s selection. the pumping station design calculation of other structures. Last, draw the general layout drawing of pumping station, the floor plan and section of the water pumping station and related drawings.
Key Words: rain water; pumping station; design calculation; process design
