Description

A kind of permeable pavement structure
Technical field
The utility model relates to a kind of road structure, relates in particular to a kind of permeable pavement structure with good ecological benefits.
Background technology
In recent years, road is all built in each city, the whole nation in a large number, and this is very easy to people's trip and has promoted Chinese economic development.But, also brought the problem of many traffic and environment aspect to the city because urban road substantially all adopts fluid-tight hard surface (i.e. " cementization " road surface).
Because the road surface can not penetrating rainwater, make rainwater be blocked, and the city is owing to the collection underground water that all exceeds standard every year, if rainfall can not replenish again timely and effectively to phreatic replenishing, will form the surface settlement district, geology and building constructions etc. is caused huge damage.Hard surface also can bring serious harm to ecology: because it makes the interchange of air on ground and air humidity reduce, quickened the formation of urban heat land effect, and hardened ground is " death ground ", can influence the ecosystem on ground, it makes the aquatic attitude factor can't normal circulation, break the balance of urban ecological system, made the normal growth of vegetation be damaged; Rainwater is that first drainage grade or open drain, the face of land by ground enters sewer during rainfall, rainwater will just can enter the city underdrainage system through the surface flow of longer distance before entering sewer, this process makes the rainwater of relative cleaning dissolve in a large amount of urban surface pollutants, cause in the process of surface flow, producing secondary pollution, if the rainwater after the secondary pollution is entered the peripheral ground natural water by urban sewerage and drainage system, will increase the weight of the degree of contamination of these natural waters; In addition, rainwater compiles on ground, concentrates in a large number on motor vehicle and the cycleway, and rainwater runs off from ground or is evaporated, and city raised dust pollution grows worse, the rising of ground average temperature, energy consumption are strengthened.
In addition, because the serious hysteresis of China's urban infrastructure development, make rainwater during season, the urban sewerage and drainage facility can not effectively satisfy the requirement of draining and flood control, the waterproof road surface of mating formation will be increased the weight of the pressure of flood of urban sewerage and drainage system undoubtedly, and this also is a lot of cities of present China produce city waterlogging during rainy season a key factor; The waterproof in addition road surface surface area water when the rainy day of mating formation, motor vehicle easily produces " floating cunning " when current, " splashing " reaches phenomenons such as " dazzles ", also can increase the potential safety hazard of urban traffic.
All drawbacks based on the above-mentioned waterproof road surface of mating formation, the waterproof more and more requirement of being adopted now of incompatibility urban ecology physical environment sustainable development of road surface of mating formation, therefore, mat formation in building at urban road that we should consider the road surface with better water permeability of selecting a kind of ecological benefits good.
