Description

Sidewalk green belt

[ technical field ] A method for producing a semiconductor device

The utility model particularly relates to a pavement green belt.

[ background of the invention ]

With the continuous advance of urbanization, the ground which can seep water originally becomes a water-tight cement land, which brings a plurality of ecological problems of urban waterlogging, ecological damage, runoff pollution and the like. Meanwhile, the greenbelt is gradually eroded, the area of wetlands such as beaches is sharply reduced, and urban inland inundation is greatly aggravated. Once a city is attacked by strong rainstorm, suddenly multiplied rainwater cannot go everywhere, the road becomes a river instantly, and a square immediately becomes a lake, so that scenes such as 'Zengguo', 'Water City', 'City seeing sea' and the like are formed. In order to solve urban inland inundation and improve urban ecological environment, China actively advocates 'sponge city' construction in recent years. The sponge city is a city which can be like a sponge, has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters and the like, absorbs water, stores water, seeps water and purifies water in the rainy period, and releases the stored water and utilizes the water when needed. The rainwater storage and release device plays roles of absorbing, storing and permeating rainwater and releasing rainwater in urban greenbelts such as sidewalk greenbelts, and is also a key part for effectively relieving urban waterlogging and strengthening rainwater ecological management.

The sidewalk green belt can eliminate visual fatigue, purify the environment, beautify the city, reduce traffic accidents and the like, and occupies an irreplaceable important position in the city. However, in the prior art, the sidewalk green belt often has no water permeable function, once a large amount of rainfall is generated, accumulated water and soil erosion are easily generated in the green belt, and urban rainfall cannot be effectively utilized.
