Description

Technical Field

[0001] The utility model relates to the technical field of rain gardens, in particular to a rain garden in a community. Background Technique

[0002] Rainwater is not only an important way to supplement groundwater in nature, but also the main source of domestic and production water in modern cities. With the continuous development of urbanization, the gradual increase in the impervious area of the urban surface has led to a continuous reduction in biological habitats, the obstruction of the self-benign cycle path of rainwater, and frequent urban waterlogging disasters, becoming a major hidden danger threatening urban safety. Therefore, different garden structures need to be built according to different building environments, and the garden next to big trees needs to prevent the damage caused by the tree roots of big trees to the garden.

[0003] Traditional rain garden designs usually focus on aesthetics, but lack consideration in terms of structural stability and functionality. For example, the lack of effective edge protection measures makes the garden vulnerable to damage by human or natural factors; at the same time, the design of tree pits often ignores the importance of air permeability for tree growth. These problems not only affect the service life of rain gardens, but also limit their wider application in urban greening. Content of the Utility Model
