Abstract
The invention relates to rainwater grates capable of separating initial rainwater runoffs. The rainwater grates capable of separating initial rainwater runoffs comprises a concrete base plate (7) and water-permeable ports (6) formed in the concrete base plate, wherein water passing galleries (5) are formed at the two sides of each water-permeable port (6), the scale height of each water-permeable port (6) is larger than that of each water passing gallery (5), and arc water catchment ports (4) are formed in the two ends of each water passing gallery (5). The rainwater grates capable of separating initial rainwater runoffs has the advantages of being capable of separating the initial rainwater runoffs from the runoffs in the middle and later periods, reducing the water amount entering the city rainwater pipe network and lightening the water processing load of sewage plants on one hand, making full use of the potency that roadside green detain and absorb the initial rainwater runoffs so that road surface source pollutants can be reduced on the other hand, and being capable of effectively relieving even solving the problem of city surface source pollution due to the fact that rainwater runoffs scour roads in the rainfall process.
Description
Technical field
The invention belongs to city surface source pollution control technology field, be specifically related to a kind of rain grid made that can separate the early-stage rainwater runoff.
Background technology
Along with the continuous expansion of China's city size, huge variation is occurring in land use pattern, a large amount of waterproof ground occurred at present, and the surface runoff coefficient enlarges markedly, and the formed run-off of Urban Rain was much larger than the past.In rainfall, rainfall runoff washes away the one of the main reasons that city surface source pollution that road causes has become the urban water-body water quality deterioration.The urban highway traffic load is large, and floor space is many, and the generation intensity of its pollution of area source load is greater than the waterproof underlying surfaces such as roofing, square, the key object that should control as city surface source pollution.Wherein, the rainfall initial stage has formed first flush to road, and the formed Initial Runoff of early-stage rainwater has comprised most roadway pollutants, as long as Initial Runoff and later stage runoff detachment can be processed separately, just can greatly reduce the contaminant capacity of road pollution of area source.
China's urban road both sides adopt rain grid made to add roadside greenbelt configuration mostly, the road rain water runoff formed in rainfall sees through rain grid made and enters the municipal wastewater pipeline, on the one hand a large amount of road surface source pollutants follow rainwater to enter municipal wastewater treatment plant, load and the cost of the Sewage Plant sewerage treatment of increasing.The ability of the rainwater purification of roadside greenbelt is not fully utilized on the other hand.Process the initial rainfall runoff if can effectively utilize the effect of the pollutant purification of roadside greenbelt, can reduce the amount of rainfall that enters city planting ductwork on the one hand, reduce Sewage Plant water treatment load, the sewage clarification potential that can give full play on the other hand the roadside greenbelt absorbs the pollutant in the degraded Initial Runoff, effectively reduce surface runoff coefficient energy processing section Runoff contaminants, effective alleviation even solves the rainfall rainfall runoff and washes away the city surface source pollution problem that road causes.
Summary of the invention
Technical problem to be solved by this invention just is to provide a kind of rain grid made that can separate the early-stage rainwater runoff, it substitutes existing trackside rain grid made, the Initial Runoff that can will contain a large amount of road surface source pollutants the initial stage causes the roadside greenbelt, realize on the one hand separating of initial stage road rain water runoff and middle and later periods runoff, the sewage clarification potential of giving full play on the other hand the roadside greenbelt absorbs the pollutant in the degraded Initial Runoff, effectively reduce surface runoff coefficient energy processing section Runoff contaminants, effective alleviation even solves the rainfall rainfall runoff and washes away the city surface source pollution problem that road causes.
Solution of the present invention is to realize by such technological means, and it comprises concrete substrate and the permeable mouth be located on concrete substrate, and the water gallery was offered in described permeable mouthful of both sides, and permeable mouthful of absolute altitude was greater than water gallery absolute altitude.
Because permeable mouthful of absolute altitude in the present invention was greater than water gallery absolute altitude, the rainfall Initial Runoff carries most roadway pollutants and enters the roadside greenbelt through the water gallery, thereby avoided early-stage rainwater to enter municipal pipeline, along with rainfall duration increases, the rainwater on road surface runoff increases gradually, rainwater covers the rainwater gallery and enters municipal pipeline through permeable mouth, thereby has effectively realized the shunting of early-stage rainwater runoff and middle and later periods rainfall runoff.
The technique effect that the present invention has is: realize the shunting of road Initial Runoff and middle and later periods runoff, reduce in rainfall the sewage clarification potential that can give full play to again the roadside greenbelt when Sewage Plant rainwater is processed load and absorb the pollutant in the degraded Initial Runoff, effectively reduce surface runoff coefficient energy processing section Runoff contaminants, effective alleviation even solves the rainfall rainfall runoff and washes away the city surface source pollution problem that road causes.
The accompanying drawing explanation
Accompanying drawing of the present invention is described as follows:
Fig. 1 is plan view of the present invention;
Fig. 2 is schematic three dimensional views of the present invention;
Fig. 3 is use schematic diagram of the present invention.
In figure: 1. road surface greenbelt; 2. rain grid made; 3. road; 4. arc charge for remittance mouth; 5. cross the water gallery; 6. permeable mouthful: 7 concrete substrates.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As depicted in figs. 1 and 2, the present invention includes concrete substrate 7 and be located at permeable mouthful 6 on concrete substrate, water gallery 5 was offered in described permeable mouthful of 6 both sides, and permeable mouthful of 6 absolute altitudes were greater than water gallery 5 absolute altitudes.
As depicted in figs. 1 and 2, crossing water gallery 5 two ends is arc charge for remittance mouth 4, is conducive to collect the rainwater on road surface and to the roadside greenbelt early-stage rainwater of releasing.
The agent structure that above-mentioned concrete substrate 7 is rain grid mades and main load-bearing unit.
As shown in Figure 3, after rainfall, relation due to road grade, the waterproof earth's surface of road 3 starts to form surface flow, the initial rainfall runoff has formed the first souring on the waterproof ground of road, and most of road surface source pollutants follows the initial rainfall runoff to flow through water gallery 5 after the arc charge for remittance mouth 4 of rain grid made 2 of the present invention confluxes under the effect of road grade, avoid permeable mouthfuls 6 enters roadside greenbelt 1.
Increase along with rainfall duration, the road rain water run-off increases gradually, the water yield of flowing through arc charge for remittance mouth 4 and crossing water gallery 5 increases gradually until covered water gallery 5, most middle and later periods rainfall runoff enters storm sewer through permeable mouthful 6, thereby has realized the shunting of rainfall Initial Runoff and middle and later periods runoff.
One aspect of the present invention realizes separating of initial stage road rain water runoff and middle and later periods runoff, rainfall interception initial stage road runoff reduces the Sewage Plant rainwater and processes load, the sewage clarification potential that can give full play to again on the other hand the roadside greenbelt absorbs the pollutant in the degraded Initial Runoff, effectively reduce surface runoff coefficient energy processing section Runoff contaminants, effective alleviation even solves the rainfall rainfall runoff and washes away the city surface source pollution problem that road causes.
