Description

Technical Field

[0001] The utility model belongs to the technical field of sponge cities, and particularly relates to a sponge city park based on a lake body and a wet pond. Background Art

[0002] Short-term heavy rainfall is likely to cause urban waterlogging, which not only increases the drainage pressure of urban municipal pipe networks but also easily causes personal and property losses. To avoid urban waterlogging, the municipal construction has adopted various mitigation methods, among which there is the concept of sponge cities.

[0003] Building a sponge city requires "sponge bodies". Urban "sponge bodies" include not only water systems such as rivers, lakes, and ponds but also urban supporting facilities such as green spaces, gardens, and permeable road surfaces. Rainwater infiltrates, stores, purifies, and is reused through these "sponge bodies", and finally the remaining part of the runoff is discharged through pipe networks and pumping stations, thereby effectively improving the standard of the urban drainage system and alleviating the pressure of urban waterlogging.

[0004] In cities, how to combine multiple types of "sponge bodies" and create a beautiful environment has become an urgent problem to be solved in this field. Summary of the Utility Model
