Description
Technical field
The present invention relates to a kind of road surface, the double useless pervious concrete pavements of especially a kind of novel sponge body.
Background technology
Its original looks is gradually changed with continuous flourishing and development, the earth of World Economics.Urban construction day is new
The moon different, fast development, public building, house, road construction cause ground surface environment to harden, and almost change the life for building ground completely
State environment, atmospheric evaporation circulation are affected, and cause air humidity in urban area to reduce, and temperature rise, form " heat island effect
Should ".This " tropical island effect " is such that city is sultryyer in summer, and dust increases in air, and people's life is increasingly felt not
Comfortably, the health of the mankind is threaten, hardened ground causes rainwater almost water can not be descended to be supplemented over the ground, and water resource utility model will
Cause arid, sandstorm year by year further frequent.The many north cities in China, including capital Beijing, sand and dust frequently occur in recent years
Sudden and violent phenomenon is exactly the example that environmental ecology wrecks.The ecology that city water resource is destroyed and is lost in as becoming increasingly conspicuous is asked
Topic, mainly there is the reason for five aspects：
1st, sewage is directly discharged into urban river, lake, causes a large amount of clean surface water to become sewage, loses value；
2nd, the natural environment of ground water is destroyed, and Wetland Area is reduced, river course hardening etc. so that Ecology occurs
Change, water loses self-purification function；
3rd, garbage loading embeading, herbal sprinkling, snowfall salting etc.；
4th, industry, inhabitation colony exhaustive exploitation underground water, level of ground water decline and land subsidence are caused so that urban architecture
It is on the hazard；
5th, road surface hardening prevents rainwater from permeating the ground, and in excess surface water, influences urban health and traffic, or heavy rain it
Afterwards, the water for flowing into sewer increases, and increases huge processing load to the drainage pipeline in city and sewage treatment plant.
How to solve water resource ecological environment problem, protect our area so that people have a full ecological, from
So, comfortable living environment, the problem of just having to pay much attention in the process of sustainable development as people.And green ring
Health care material also just turns into the first choice of urban construction.
After Bartlit, cement, conventional ceramic square brick etc. pave road, because they are waterproof and airtight, rain
When, these hardening road surfaces can not drink up the rain in time, but in vain allow substantial amounts of rainwater to flow to rivers, in high temperature evaporation
Under, the road surface of this hardening is due to no water retaining function, it is impossible to has moisture evaporation, so as to destroy the water circulation of the earth, makes
The air exchange and air humidity for obtaining road surface reduce, and air quality is deteriorated, and promotes " urban heat land effect " to a certain degree, also unfavorable
In the haze phenomenon for improving puzzlement China most cities.
In the last few years, rain is met flooded to evolve as the chronic illness of China big and medium-sized cities.Conventional curing road surface, due to a large amount of
Rainwater can not permeate the ground in time, turn into one of main pushing hands of urban waterlogging.On the one hand, urban rainwater crossing current overflows and can melted
Enter substantial amounts of urban pollutant, such as automobile emission, house refuse, dust and toxic compounds matter on construction site, city
Agricultural chemicals of meadow sprinkling etc., it is all these to flow directly into rivers, significantly river pollution can be caused.On the other hand, greatly
The city ponding of area, not only influences the appearance of the city, influences normal work and the life of people, and prolonged ponding can grow mosquitos and flies,
The health in strong influence city, easily cause the prevalence of infectious disease.Because a variety of causes, road surface can constantly go out in urban construction
Condition of construction is now repeated, if floor slab uses common material (pitch, cement, stone material), these materials are usually cannot
Reuse, so not only increasing municipal works expense, and produce a large amount of rubbish and inevitably produce other
Pollution.
2014, house town and country construction portion externally issued《Sponge urban construction technical manual》, it means that China from now on
Rainwater will be become the wealth that quenches one's thirst from burden, build reason by the construction of urban drainage prevention waterlogging system no longer based on " repairing big pipe "
Thoroughly transformation will be occurred by reading.It is that conservation culture is built to build with nature accumulation, naturally osmotic, the sponge city of self-purification function
If important content, be the important embodiment for realizing urbanization and environmental resource coordinated development, and China's urban construction from now on
Significant task.
As its name suggests, sponge city refers to that city can adapt to environmental change and reply disaster freely as sponge
Etc. have good " elasticity ", water suction when rainy, water storage, infiltration, water purification, it is necessary to when by the water stored " release " and be subject to
Utilize.Sponge urban construction should follow the principles such as Ecology Precedence, and natural way is combined with artificial measures, ensure city row
On the premise of water prevention waterlogging safety, accumulation, infiltration and purification of the rainwater in urban area are realized to greatest extent, promotes rainwater resource
Utilization and ecological environmental protection.In sponge Process of Urban Development, the system of natural precipitation, surface water and groundwater should be planned as a whole
Property, coordinate each links of water circulation use such as feedwater, draining, and consider its complexity and chronicity.
Building sponge city will have " cavernous body ".City " cavernous body " both includes the water systems such as river, lake, pond, also including green
Ground, garden, city auxiliary facility as permeable road surface.Rainwater by being oozed under these " cavernous bodies ", it is stagnant store, purification, reuse,
Last remainder runoff, so as to effectively improve the standard of sewerage system, is extenuated in city by being arranged outside pipe network, pumping plant
The pressure of flood.
Existing porous pavement substantially meets the requirement of " cavernous body ", compensate for the impermeability of prevailing roadway.It with
Existing certain compression strength unlike prevailing roadway, has certain permeable breathable again.Such as Chinese invention patent
CN200981968Y discloses a kind of water penetration pavement, includes the surface layer that does of porous pavement brick of porosity 10~15%
Single Stone or sand-free coarse porous concrete gap cement concrete are punished with the cement of porosity 18~20%.Because porosity is larger, because
This improves the water penetration on road surface, but it is more complicated to prepare macroporous technique, and its higher crushing resistance of porosity is poorer, and
Protection to ecological environment is also very limited.
