Abstract: With the demand of beautiful water and beautiful scenery in urban and rural areas, the construction of small bidirectional pumping projects tends to be extensive. Most of the previous studies focused on the construction of large bidirectional pumping stations at urban river mouth, but the construction of small and simple bidirectional pumping projects in urban and rural area is still lack of systematic summary. This paper summarizes and analyzes the layout scheme and application characteristics of the small-scale irrigation and drainage pumping station project in Jiangsu Province, and puts forward a new scheme, bidirectional pumping of submersible axial pump (high and low culvert combined), in view of the landscape demand. After comparing the advantages and disadvantages of various schemes, the applicable conditions, the application examples and parameters of various schemes are analyzed. It can provide a useful reference for the selection and arrangement of small pumping station with bidirectional pumping requirements, especially for the small pumping station with high landscape demand.
