Description
Technical field
The present invention relates to " sponge city " permeable pavement fields, a kind of porous pavement more particularly, to quaternity and its
Preparation method.
Background technique
The propulsion of urbanization process makes city produce many ecological environment problems after exploitation, wherein occupying on people influences most
Big environmental problem is superfluous no more than surface sealing road surface, although the road surfaces such as cement, concrete, pitch facilitate going out for the people
Row, but the problem also directly results in city water percolating capacity deficiency when in face of rainfall, and water percolating capacity deficiency further results in city
A series of problems, such as waterlogging, traffic paralysis, water pollution.To solve problems, country proposed construction " sponge in 2012
The theory in city ".So-called " sponge city ", that is, require city to focus on harvesting, discharge, utilizing for municipal water in development process
Deng.Permeable pavement is mentioned extensively as the front end for solving the problems, such as city " cavernous body " under the overall background in construction " sponge city "
Out.Permeable pavement has 1, good permeable, permeability, and rainwater can be made to rapidly permeate into underground, supplements the soil water and underground water,
Soil moisture is kept, the life condition of urban ground plant and edaphon is improved.2, it is can absorb moisture and heat, adjustably
The temperature and humidity of table local space has biggish effect to adjusting urban microclimate, alleviating urban heat land effect.3, it can reduce city
Draining and pressure of flood have good effect to the pollution that prevents public waters and processing sewage, make on road not ponding.Its
Middle permeable pavement brick is even more to have obtained unprecedented concern as city and the contact point of resident.
But water-permeable brick needs to carry out prefabrication molding, be then transported to need to carry out the place of municipal permeable pavement into
Row construction, it is not only uneconomical a series of problems, such as facing workshop organizational system, brick stacking storage in this process, transport, simultaneously
Also more discharges have been manufactured, very not environmentally；And using the porous pavement of water-permeable brick due to the isolating property between water-permeable brick,
The isolating property of water-permeable brick and subbase course material, the intensity that will lead to entire ground surface material are difficult to be promoted.
Quaternity porous pavement of the invention can effectively combine surface material with base material, by this
Method can efficiently solve the above problem and more economical, more environmentally-friendly, while can also manufacture successional porous pavement, simultaneous
Care for mechanical property, comfort property, performance attractive in appearance.
