The two useless pervious concrete pavement of a kind of Novel sponge body
Technical field
The present invention relates to a kind of road surface, the two useless pervious concrete pavement of especially a kind of Novel sponge body.
Background technology
Along with continuous prosperity and the development of World Economics, the earth changes its original looks gradually.Urban construction is maked rapid progress, fast development, and public building, house, road construction make ground surface environment harden, almost change the ecological environment building ground completely, atmospheric evaporation circulation is affected, and causes air humidity in city area to reduce, temperature raises, and is formed " heat island effect ".This " heat island effect " makes city in summer sultryyer, in air, dust increases, people's life more and more feels uncomfortable, threaten the health of the mankind, hardened ground makes rainwater almost cannot supplement underground water, water resource utility model will cause arid year by year, and sandstorm is further frequent.The many North Cities of China, comprise Beijing, capital, and frequently sandstorm phenomenon occurring in recent years is exactly the example that environmental ecology wrecks.City water resource is destroyed and the ecological problem becoming and become increasingly conspicuous that runs off, and mainly contains the reason of five aspects:
1, sewage directly enters urban river, lake, causes a large amount of clean surface water to become sewage, loses value;
2, the natural environment of ground water is destroyed, and Wetland Area reduces, river course sclerosis etc., and Ecology is changed, and water loses self-purification function;
3, garbage loading embeading, herbal sprinkling, snowfall salting etc.;
4, industry, inhabitation colony exhaustive exploitation underground water, causes groundwater table to decline and land subsidence, urban architecture is on the hazard;
5, road surface sclerosis makes rainwater not permeate the ground, and in excess surface water, affects municipal sanitary and traffic, or after heavy rain, the water yield flowing into sewer increases, and increases huge processing load to the drainage pipe in city and Wastewater Treatment Plant.
How to solve water resource ecological environment problem, protect our area, make people have a full ecological, natural, comfortable living environment, just become the problem that people must pay much attention in the process of sustainable development.And green structural material also just becomes the first-selection of urban construction.
After Bartlit, cement, conventional ceramic square brick etc. pave road, because they are waterproof and airtight, when raining, the road surface of these sclerosis can not drink up the rain in time, but a large amount of rainwater that allows in vain flows to rivers, under high temperature evaporation, the road surface of this sclerosis is not owing to having water retaining function, moisture can not be had to evaporate, thus destroying the water circulation of the earth, the interchange of air on road surface and air humidity are reduced, and air quality is deteriorated, to a certain degree promote " urban heat land effect ", be also unfavorable for the haze phenomenon improving puzzlement China most cities.
In the last few years, rain is met flooded must to develop into the chronic illness of China big and medium-sized cities gradually.Conventional curing road surface, because a large amount of rainwater can not permeate the ground in time, one of main pushing hands becoming urban waterlogging.On the one hand, urban rainwater crossing current overflows and can incorporate a large amount of urban pollutants, as automobile emission, household garbage, the dust on building site and toxic compounds matter, agricultural chemicals that meadow, city is sprayed etc., all these flow directly into rivers, can cause river pollution significantly.On the other hand, large-area city ponding, not only affects the appearance of the city, and affect normal work and the life of people, long ponding can grow mosquitos and flies, affects the health in city greatly, easily causes the popular of infectious disease.Due to a variety of causes in urban construction, road surface constantly can duplicate condition of construction, if floor slab uses common material (pitch, cement, stone material), these materials are generally cannot be reusable, so not only increase municipal engineering expense, and produce a large amount of rubbish and the inevitable pollution producing other.
2014, house town and country construction portion externally issues " sponge urban construction technical manual ", this means that the construction of the system of China's urban drainage prevention waterlogging from now on will no longer based on " repairing large pipe ", rainwater is become from burden the wealth that quenches one's thirst, the theory of construction will occur thoroughly to change.Build have nature accumulations, naturally osmotic, self-purification function sponge city be the important content of Ecological Civilization Construction, being realize the important embodiment that urbanization and environmental resource develop in harmony, is also the significant task of China's urban construction from now on.
As its name suggests, sponge city refers to that city can as sponge, conforming change and tackle and freely have good " elasticity ", water suction when raining, retaining, infiltration, water purification in disaster etc., is used by the water stored " release " when needing.Sponge urban construction should follow the principles such as Ecology Precedence; natural way is combined with artificial measures; under the prerequisite guaranteeing urban sewerage and drainage prevention waterlogging safety, realize the accumulation of rainwater in city area, infiltration and purification to greatest extent, promote utilization and the ecological environmental protection of rainwater resource.In sponge Process of Urban Development, the systematicness of natural precipitation, surface water and groundwater should be planned as a whole, coordinate each links of water circulation use such as feedwater, draining, and consider its complexity and chronicity.
Build sponge city will have " cavernous body ".City " cavernous body " had both comprised the water systems such as river, lake, pond, also comprised the city ancillary facility that greenery patches, garden, permeable road surface are such.Rainwater by oozing under these " cavernous bodies ", stagnantly to store, purify, reuse, last remainder footpath flows through pipe network, pumping plant is arranged outward, thus effectively can improve the standard of urban sewerage and drainage system, extenuates the pressure of urban waterlogging.
Existing porous pavement meets the requirement of " cavernous body " substantially, compensate for the impermeability of prevailing roadway.It and prevailing roadway, unlike existing certain compressive strength, have again certain water-permeable and air permeable.Such as, Chinese invention patent CN200981968Y discloses a kind of water permeability pavement, and the cement of the surface layer that the porous pavement brick comprising porosity 10 ~ 15% does and porosity 18 ~ 20% punishes single Stone or sand-free coarse porous concrete gap cement concrete.Because porosity is comparatively large, therefore improve the water permeability on road surface, but it is more complicated to prepare macroporous technique, and porosity its crushing resistance higher is poorer, and also very limited to the protection of ecological environment.
