Description

A prefabricated green belt structure

technical field

The utility model relates to the field of road construction, in particular to an assembled green belt structure.

Background technique

In recent years, the country has vigorously developed and built sponge cities to alleviate the urban heat island effect, improve the functions of urban ecosystems and reduce the occurrence of urban flood disasters. Very important content. In the process of urban development, a large number of hard pavements have changed the original ecological characteristics, making the rainfall unable to infiltrate in time, thus forming surface runoff. The traditional urban drainage system is difficult to adapt to the runoff peak formed during heavy rainfall, resulting in Urban flooding. Reducing the hard pavement of the road surface and the ground is a way to reduce surface runoff, but if the water flow directly seeps under the road, it will cause instability or even damage to the foundation soil under the road surface, which will affect the normal use of the road. Technical seepage cannot make the water flow on the road surface drain quickly. Therefore, there is a need for a fast channel to assist the rapid discharge of surface runoff and accumulated water on the road, so that light rain does not accumulate water, heavy rain does not cause waterlogging, and promotes the development of urban rainwater circulation channels. The green belt in the middle of the road is a strip for greening, which can eliminate visual fatigue, purify the environment, beautify the city, reduce traffic accidents, etc., and occupies an irreplaceable important position in the city.

In addition, the quality of traditional curb laying is directly related to the laying technology level of the workers. The cement joints between the curbs will affect the appearance. At present, after a certain period of laying of traditional curbstones, 80% of the curbstones will be damaged to varying degrees, such as falling blocks, cracks, etc., which will affect the appearance and use of the city. The replacement of traditional curbstones is relatively time-consuming and laborious. Although the soil layer of the green belt has a certain water permeability function, it mainly depends on the penetration of the pores in the soil, which is greatly affected by the nature of the soil, the size of the pores, the connectivity of the pores, and the degree of saturation of the soil. According to the green belt, it is impossible to realize the rapid drainage and discharge of short-term heavy rainfall and heavy rain.
