Description

A kind of construction method on sponge urban ecology diafiltration ground
Technical field
The invention belongs to urban construction field of environment protection, more particularly to a kind of construction method on sponge urban ecology diafiltration ground.
Background technology
As urban construction develops rapidly, the construction of large amount of building and road etc. makes city hardened ground area quickly increase Add, at present, the paving design of the most of urban road in China, public square etc. is used with " developing in harmony naturally, ecological good Property cycle " the impermeable water type close-graded concrete disagreed of theory and stone slab paving structure.The large area of this paving Using that can be adversely affected to urban ecological environment, the normal circulation of water resource is destroyed, it is straight to prevent rain (snow) water It connects and infiltrates through ground, blocked supplement of rain (snow) water to urban groundwater resource;The negative climatic effect in city is exacerbated, is deteriorated Urban ecology, it is this it is fluid-tight mat formation and surrounding cities building collective effect, can increase city " tropical island effect " and city City's noise;Security risk is increased, with increasingly sharpening for city " rainwater disease ", the ground pavement of these surface compacts is in the rainy day Since hardened ground prevents to cause large area ponding from timely draining at hypsography low-lying, generate " water drift phenomenon ", the rainy day is made to drive a vehicle Phenomena such as generating " drift is slided ", " splashing ", " Night Glare ", to pedestrian's trip and vehicle traveling is made troubles and security risk. The gradient suitable for when, due to the Quick drainage pattern of hardened ground, aggravate urban water shortage phenomenon, be unfavorable for adjusting mesoclimate. With the proposition of sponge city concept, people are more desirable to can have a kind of ecotypic road surface to replace existing hard surface, lead to These can be solved the problems, such as by crossing ecological diafiltration techniques, and the ecotype is laid with extensively dankly using ecological diafiltration techniques in city Face, this has become the common practice of many ecocities in the world.Environmental pervious surface can reduce the tropical island effect in city, adjust Mesoclimate is saved, is also beneficial to the precipitation in city, city can be helped to store more rainwater.This can mitigate city water resource danger Machine, and the water content in soil can be increased, regulated the climate, so as to improve the ecological environment in city.
Invention content
It is above-mentioned there are problem the purpose of the present invention is being directed to, provide a kind of ecology, environmental protection, green sponge urban ecology ooze The construction method on ground is filtered, this method can increase the porosity on ground and rain penetration rate, infiltrate the rainwater of soil, not only may be used With recharging groundwater, it can also mitigate city rain flood load, hence it is evident that improve urban ecological environment.
Technical scheme of the present invention:
A kind of construction method on sponge urban ecology diafiltration ground, the sponge urban ecology diafiltration ground by underlayment, Base, filter layer, pervious surface composition, construction method include the following steps:
1) it is percolated the preparation of material
Diafiltration material is made using natural material, obsolete material and artificial material combination, and wherein natural material is natural Sandy soil, zeolite, quartz sand, timber, meadow soil or sub- sandy soil, obsolete material are coal ash, crab shell or solid waste, artificial material Expect for tunica fibrosa, activated carbon or Zero-valent Iron, according to percolation effect, with reference to economy, natural material, obsolete material and artificial material Material mixture ratio be 7:1-2:0.5-1;
2) underlayment and base are laid with
Roadbed is excavated according to the requirement of design, clears up the earthwork, checks longitudinal slope, horizontal slope and sideline, modifies roadbed, it is levelling to roll Closely knit, compacting factor is at least up to 95%, underlayment is laid with above the roadbed excavated, underlayment is by lime, flyash and soil Composition, the weight ratio of lime, flyash and soil is 10:24:66, levelling compacting after underlayment is completed, compacting factor is at least up to 95%, before end is rolled, once make its longitudinal direction pleasantly with land leveller is flat eventually, road camber and superelevation meet design requirement, finally Pine is gently harrowed on surface, and moistening of sprinkling water, be then laid with base, base is cement stabilized macadam layer, is stablized with cement, flyash, cement It is accurately weighed with gathering materials, is blended according to continuous grading ratio, record mixing time plus water time and amount of water ensure blending matter Amount, levelling compacting after uniformly paving, compacting factor are at least up to 93%, and compacting rear surface answers smooth no wheelmark or protuberance, and section Correctly, road camber meets the requirements, and after completion of works, the surface of Construction of Cement Stabilized Macadam should keep smooth, cleaning;
3) ground underlay diafiltration material-paving filter layer
The laying of filter layer is the diafiltration material prepared on ground and both sides of the road shallow-layer ground surface consolidation, thickness 3- 10cm, making be percolated material before, base should clean up, diafiltration material through pave with after integer, immediately in overall with range It inside carries out rolling 6-8 times, both sides multiple pressure 2-3 times on road surface, in roller compaction process, tide will be remained by being percolated the surface of material It is wet;
4) kerbstone is installed and is laid with pervious surface
Kerbstone is laid with before pervious surface is laid with, there are 5cm gaps every 10m for kerbstone, and cement mortar is used after paving Then jointing and in time backfill protection are laid with pervious surface, the material of pervious surface is water-permeating pitch mixed material or Regenerated Bone Expect water-permeable brick, use spreading thickness during water-permeating pitch mixed material as 1.0-1.2cm.
It is an advantage of the invention that:The sponge urban ecology diafiltration ground construction method that this method provides is ecological, environmentally friendly, green Color has preferable repeatability and showing property, can increase the porosity on ground and rain penetration rate, infiltrate the rainwater of soil, no Only can recharging groundwater, can also mitigate city rain flood load, hence it is evident that improve urban ecological environment;Significantly improve road surface and surrounding soil The water storage performance of earth and pollutant purification ability, reduce the generation of water pollutant and road safety accident, and appropriateness adjusts part Weather, hence it is evident that the problems such as slowing down city " rainwater disease ", " tropical island effect " and soil water shortage and city noise is solving city life While state, environmental and safety problems, good reference function is played to structure urban ecology road.
