Description
Technical Field
The utility model relates to a permeable pavement technical field, concretely relates to ecology permeable pavement structure.
Background
Along with the process of large-scale urban construction, a series of ecological environmental problems caused by urbanization are increasingly highlighted. The urbanization hydrological effect is one example. The change of the original natural ecological environment by urbanization influences the processes of rainfall, evaporation and rainwater runoff and confluence, and causes the problems of urban water resource shortage, urban non-point source pollution and the like, and the change and the confluence of the urban natural ecological environment and the urban natural ecological environment jointly form the urban hydrological effect. One important manifestation of the urbanized hydrological effect is the change of urban rainwater runoff and confluence characteristics. Due to the fact that impervious areas such as roofs and hard ground are greatly increased, rainwater runoff forming time is shortened, and rainwater flood peak flow is increased. On one hand, the problem of urban inland inundation can be caused (inland inundation caused by Beijing rainstorm in summer of 2012 is an example), and on the other hand, the problem of rainwater runoff pollution can be caused because the violent scouring action generated by rapidly formed runoff of the underlying surface brings roof pavement sediments, garbage generated by pedestrians and vehicles into urban water. More seriously, a large amount of oil stain substances on the urban motor vehicle lanes can cause the initial storm runoff to contain a large amount of carcinogenic substances, such as benzopyrene, benzanthracene and the like, and the carcinogenic substances can be enriched through a food chain after entering a water body, so that the health of human bodies is harmed.
The permeable pavement is a typical low-influence development measure for regulating and controlling urban rainwater runoff by increasing the urban permeable area. The urban rainwater runoff filter can meet the requirement of convenience of life of people, has good permeability, reduces the pollutant input of rainwater runoff on urban water, improves the urban water environment quality, and can relieve the negative influence brought by the urban process to a certain extent.
At present, the research on permeable pavement in developed countries is early and systematic, for example, a large amount of research is carried out in the aspects of permeable pavement runoff control, pollutant reduction and the like in the United states, Canada, Australia, British and the like, abundant experience is accumulated, and the developed countries are still in the starting stage in China. In recent years, under the promotion of construction of sponge cities and beautiful villages, permeable pavements are actively popularized and applied in many domestic areas, and large-area permeable pavements such as roads, parking lots and squares are constructed. However, due to the lack of long-term monitoring data and practical experience, some permeable pavements are unreasonable in design structure and only focus on the rainwater infiltration function, and the runoff regulation and control benefits are difficult to continuously and effectively exert due to incomplete removal of non-point pollutants and detailed design consideration.
