Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment: a kind of urban water-through road structure 1, its structure is as shown in Figure 1: comprising: anti-blocking porous pavement layer 11, be provided with basic unit 13 on open gradation bed course 12, open gradation below anti-blocking porous pavement layer 11 successively, open gradation goes to a grassroots level 14 and non-compacted foundation soil 17;
Described open gradation go to a grassroots level 14 inside be provided with band perforate gutter 15.
As preferably scheme, be provided with between described open gradation lower floor 14 and non-compacted foundation soil 17 prevent soil particle block open gradation go to a grassroots level 14 geotextile layer 16.
Under normal precipitation event, first rainwater filters through anti-blocking porous pavement layer 11, and bulky grain is trapped, and makes the rainwater infiltration of relative clean.Rainwater is gone to a grassroots level after 14 through basic unit 13 and open gradation on open gradation bed course 12, open gradation again and is entered gutter 15, carries from gutter 15 to follow-up subsystem.
According to different needs, anti-blocking porous pavement layer 11 is that anti-blocking water-permeable brick or other carriers with water permeability are paved and formed.
Under large rainfall precipitation event, likely cause gutter 15 to be in full load condition, then the rainwater not entering gutter 15 will gravitate, oozes under after geotextile layer 16 and non-compacted foundation soil 17, supplements urban groundwater.
Non-compacted foundation soil 17 essence is soil particle, and after water infiltrates, soil particle exists the possibility of upwards adsorbing.But because the existence of geotextile layer 16, open gradation is gone to a grassroots level and 14 achieves relative isolation with non-compacted foundation soil 17, prevent soil particle from blocking open gradation and go to a grassroots level 14, ensure that land drainage is smooth and easy.
The present invention makes network of underground draining single for urban pavement into network of underground draining synchronous with road surface, and then the situation of road surface flood passage when there will not be city to meet large rainfall precipitation.
As shown in Figure 5: present invention also offers a kind of novel rainwater catchment system exhaust system, this rain water collecting system comprises rainwater purification subsystem 2 and overflow discharge subsystem 5, and rainwater purification subsystem 2 is connected with the gutter 15 in above-mentioned urban water-through road structure 1 respectively by pipeline with overflow discharge subsystem 5;
Rainwater purification subsystem 2, by after the Water warfare that transports in gutter 15, is delivered to again rainwater savings subsystem 3, uses in order to rainwater reuse subsystem 4 and/or overflow discharge subsystem 4.
As shown in Figure 2: described rainwater purification subsystem comprises bio-aeration pool 21 and disinfection by ultraviolet light pond 22, pervious concrete wall can be adopted to realize synchronous filtering.This part utilizes two heavy caliber concrete through transformation or plastics pipeline section composition, and wherein first paragraph installs aerator and suspension of biofilm ball filler, forms BAF; Second segment is installed ultraviolet disinfecting and is carried out ultraviolet disinfection, and the rainwater after sterilization has been removed organic pollution and heavy metal, then is delivered to rainwater savings subsystem 3.
The essence of rainwater purification subsystem 2 saves subsystem 3 for being connected urban water-through road structure 1 with rainwater, water quality after process is up to state standards, rainwater COD, SS index after the process specified in the afforestation of city water supply standard namely in " urban sewage reutilization-urban reclaimed water water quality " (GB/T18920-2002) and " building with community rainwater utilization project technical specification " (GB50400-2006).
As shown in Figure 3: described rainwater savings subsystem 3 comprises upper strata original soil layer 31, is provided with upper strata sand bed 32, rainwater-collecting module, lower floor's sand bed 37 and lower floor's original soil layer 38 under upper strata original soil layer 31 successively.
When meet rainfall time, rainwater from upper strata original soil layer 31 under ooze, filtered by upper strata sand bed 32, permeate the ground through lower floor's sand bed 37 and lower floor's original soil layer 37 again after walking around rainwater-collecting module, supplement urban groundwater.
Rainwater-collecting module comprises the rainwater collection header 35 of multiple modularity assembling, and all rainwater collection headers 35 are all coated by geomembrane 33, and the rainwater while preventing the rain water runoff collected in guarantee rainwater collection header 35 and the external world breathe freely;
Described rainwater collection header 35 is connected with outlet 36 with inlet tube 34 respectively, and the water of rainwater purification subsystem 2 imports by inlet tube 34, and water is delivered to rainwater reuse subsystem 4 and/or overflow discharge subsystem 5 by outlet 36.
Rainwater collection header is that renewable environmental protection PP (polypropylene) is made, and has intensity high, the feature of stable chemical nature.Modular assembling mode is very flexible, can carry out efficiently assembled according to actual needs, not limit by place size.Because module adopts the method for splicing mutually, construction is simple, without the need to big machinery, and can become case by Assembling, can realize excavating backfill on the same day same day.Whole Eco-Environment System can not be destroyed behind the buried underground of rainwater collection header of PP material, safeguard simple, and can be recycled.
As shown in Figure 4: rainwater reuse subsystem 4 can comprise the common middle water storing mechanisms such as greening shower nozzle 41, city fountain nozzle 42 and community reservoir 43.Each middle water storing mechanism can be communicated with outlet 36 respectively by pipeline.This spline structure can improve the effective rate of utilization of city undrinkable water, alleviates the situation of urban water shortage greatly.
As another kind of Land use systems, rainwater reuse subsystem 4 also can comprise the devices such as city car-washing reservoir, road sweeper filler and factory cooling pond.
Described overflow discharge subsystem 5 can be city natural bioremediation or city artificial swamp.Heavy rain also directly can be disposed to wetland by independent pipeline by the gutter 15 in a kind of urban water-through road structure 1.Wetland is the transitional area unified between aquatic ecosystem at terrestiral ecosystem, under soil is immersed in the specific environment in water, grows the feature plant of a lot of wetland.
After have employed said structure, the present invention utilizes the high pore structure of water-permeable pavement that rainwater can be allowed effectively to permeate the ground, reduce city overland runoff, by rainwater " ooze, store, only, with, arrange " combine, realize the sustainable development in city.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can be without departing from the spirit or scope of the present invention, realize in other embodiments, the part be not described in detail, for prior art, do not repeat at this.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and feature.
