Description

A kind of construction method on sponge urban ecology diafiltration ground
Technical field
The invention belongs to urban construction field of Environment Protection, particularly to the structure side on a kind of sponge urban ecology diafiltration ground Method.
Background technology
Along with urban construction develops rapidly, the construction of large amount of building and road etc. makes city hardened ground area fast Speed increases, and at present, the paving design of the most urban road of China, public square etc. all uses with " natural Coordinated development, benign ecological cycles " the contrary impermeable water type close-graded concrete of theory and stone slab mat formation knot Structure.Urban ecological environment can be adversely affected by the large area use of this paving, destroys water resource Normal circulation, prevent rain (snow) water and directly infiltrate through ground, blocked rain (snow) water to city Supplementing of lower water resource;Exacerbate the negative climatic effect in city, be degrading urban ecology, this fluid-tight Mat formation and the effect jointly of surrounding cities building, city " tropical island effect " and city noise can be increased;Add Potential safety hazard, along with increasingly sharpening of city " rainwater sick ", the ground pavement of these surface compacts the rainy day by In hardened ground make at hypsography low-lying can not draining in time, cause large area hydrops, produce " water drift phenomenon ", Make rainy day driving produce the phenomenons such as " drift is sliding ", " splashing ", " Night Glare ", travel to pedestrian's trip and vehicle Make troubles and potential safety hazard.When the gradient is suitable, due to the Quick drainage pattern of hardened ground, city is made to lack Water phenomenon increases the weight of, and is unfavorable for regulating mesoclimate.Along with the proposition of sponge city concept, people are more desirable to can be had A kind of ecotypic road surface replaces existing hard surface, can solve these by ecological diafiltration techniques and ask Topic, uses ecological diafiltration techniques extensively to lay environmental pervious surface in city, and this has become many in the world The common practice of ecocity.Environmental pervious surface can reduce the tropical island effect in city, regulates mesoclimate, It is also beneficial to the precipitation in city, city can be helped to store more rainwater.This can relax city water resource crisis, The water content in soil can be increased again, regulate the climate, thus improve the ecological environment in city.
Summary of the invention
It is an object of the invention to for above-mentioned existing problems, it is provided that a kind of ecology, environmental protection, green sponge city The construction method on ecological diafiltration ground, the method can increase porosity and the rain penetration rate on ground, infiltrates soil The rainwater of earth, is possible not only to recharging groundwater, also can alleviate city rain flood load, hence it is evident that improve urban ecology ring Border.
Technical scheme:
The construction method on a kind of sponge urban ecology diafiltration ground, described sponge urban ecology diafiltration ground is by base Layer, basic unit, filter layer, porous pavement composition, construction method comprises the following steps:
1) preparation of diafiltration material
Diafiltration material is to utilize natural material, obsolete material and artificial material combination to prepare, and wherein natural material is Natural sandy soil, zeolite, quartz sand, timber, meadow soil or sub-sandy soil, obsolete material be coal ash, Carapax Eriocheir sinensis or Solid waste, artificial material is fibrous membrane, activated carbon or Zero-valent Iron, according to percolation effect, integrated economics, The material mixture ratio of natural material, obsolete material and artificial material is 7:1-2:0.5-1;
2) underlayment and basic unit are laid
Requirement excavation roadbed according to design, clears up the earthwork, checks longitudinal gradient, horizontal wall inscription and sideline, repair roadbed, Levelling grinding compacting, compacting factor is at least up to 95%, lays underlayment, underlayment above the roadbed excavated Being become with local soil type by Calx, flyash, Calx, flyash are 10:24:66 with the weight ratio of soil, complete the end Levelling compacting after basic unit, compacting factor is at least up to 95%, before rolling end, once makes it with land leveller is the most flat The most pleasantly, road camber and superelevation all meet design requirement, surface is finally harrowed pine gently, and it is moistening, so to sprinkle water Rear laying basic unit, basic unit is cement stabilized macadam layer, and stable with cement, flyash, cement is accurately weighed with gathering materials, and presses According to continuous grading ratio blend, record mixing time, add water time and amount of water, it is ensured that blend quality, uniformly Levelling compacting after paving, compacting factor is at least up to 93%, and compacting rear surface should be smooth without wheelmark or protuberance, and breaks Face is correct, and road camber meets the requirements, 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 road both sides shallow-layer ground surface consolidation, and thickness is 3-10cm, before making diafiltration material, basic unit should clean up, and diafiltration material is through paving and after integer, vertical I.e. carry out rolling 6-8 time in the range of overall with, in both sides multiple pressure 2-3 time on road surface, in roller compaction process, diafiltration The surface of material to remain moist;
4) kerbstone is installed and lays pervious surface
Laying kerbstone before laying pervious surface, kerbstone leaves 5cm gap every 10m, uses after paving Pointing with cement mortar and backfill protection in time, then lays pervious surface, and the material of porous pavement is permeable drip Blue or green compound or regeneration aggregate water-permeable brick, spreading thickness when using water-permeating pitch mixed material is 1.0-1.2cm.
The invention have the advantage that sponge urban ecology diafiltration ground construction method ecology that the method provides, environmental protection, Green, has preferably repeatability and showing property, can increase porosity and the rain penetration rate on ground, infiltrates soil The rainwater of earth, not only can recharging groundwater, also can alleviate city rain flood load, hence it is evident that improve urban ecological environment; Significantly improve water-retention performance and the pollutant purification ability of road surface and surrounding soil, reduce water pollutant and road The generation of security incident, appropriate regulation mesoclimate, hence it is evident that slow down city " rainwater sick ", " tropical island effect " and The problems such as soil hydropenia and city noise, while solving urban ecology, environmental and safety problems, to structure Urban ecology road serves good reference function.
