Description

Technical Field

[0001] The utility model relates to the technical field of sponge city construction, in particular to a rain garden on a science popularization display platform.

Background Art

[0002] In recent years, sponge cities have developed rapidly and relevant technologies have been greatly improved. Among them, the rain garden is an effective technology for natural rainwater purification and disposal. Rainwater runoff is filtered through the soil layer and then discharged downstream through a culvert or directly infiltrated into the soil, achieving multiple goals such as reducing peak flow, purifying rainwater, and realizing the control of total runoff volume, runoff peak, and runoff pollution.

[0003] At present, the application and practice of existing rain gardens still have certain limitations. Traditional rain gardens are generally designed in the shape of an arc-shaped depression and placed along roads, requiring relatively flat layout areas and being inapplicable to special sites with poor drainage, steep slopes, or other restrictions. In addition, the design forms and landscape functions of rain gardens are relatively single, and it is difficult to match the landscapes of all types of project plots only as a rainwater collection engineering technology.

[0004] The rain garden on the science popularization display platform of the utility model solves the above-mentioned practical problems, is applicable to relatively steep slope environments or relatively complex terrains, can also increase the rainwater storage volume and enhance the treatment efficiency of rainwater pollutants while saving the construction area of the rain garden. In addition, this rain garden has a science popularization display function, clearly showing people the whole process of rainwater transmission, precipitation, purification, and collection, providing an immersive science popularization experience space, and taking into account the best ecological benefits and landscape values.
