A kind of have the rain inlet structure cutting dirty and diverter function
Technical field
The present invention relates to urban road rainwater treatment technical field, the rain inlet structure particularly in a kind of urban road rain processing system, specifically a kind of have the rain inlet structure cutting dirty and diverter function.
Background technology
China is in the critical period of building a well-off society in an all-round way, and construction speed is unprecedented, and scale is unprecedented.Road occupies very important status in city construction planning and building, and under Rapid Urbanization, road impermeable surface area constantly increases, and rainwater cannot ooze down and cause surface rain runoff to increase.At present, the ratio that China's urban road accounts for construction land is generally 10 ~ 15%, and abroad some city is even more than 30 ~ 40%.Therefore, in order to coordinate the contradiction in urban development between human and environment, how to hold the relation of road and the urban environment day by day increased, deal carefully with interference and impact that road construction brings environment, water resource etc., just become a significant problem being worth taking seriously.
At present, the road drainage in China city design or based on pipe drainage, in some outskirts of a town or the combination area of city and country based on irrigation canals and ditches draining, the thought total to rainwater is still embodied on " row " word.And the drawback that the quickening of urbanization process makes traditional cities road drainage is day by day obvious, thisly just expose following subject matter with the road drainage system simply discharged as single mode and target:
1, the road pressure that drains off floodwaters is large: in urban sprawl process, the sclerosis underlying surface that a large amount of natural ground is progressively included road replaced, and road perimeter zone hardening ratio also increases day by day; The increase of Permeable stratum area causes city integrated runoff coefficient to increase, heavy rain confluxes rapidly, run-off and runoff peak value are multiplied, road drainage system is also usually responsible for the draining task of periphery gathering ground, therefore the discharge pressure of road must be strengthened, flooding risk increases, and road safety coefficient also declines thereupon; The many cities of China annual rainy seasons causes huge loss and ill effect due to road flood, and the serious ponding etc. as the flood on the road flood damage in Jinan in 2007 and the ground such as Anhui, Chongqing, Beijing many places road, overpass bridge in recent years causes huge the economic loss even loss of people's lives and properties;
2, pavement runoff is seriously polluted: it is the main source that city overland runoff pollutes that pavement runoff pollutes, and city overland runoff pollution is the second largest non point source of pollution being only second to agricultural pollution; Account for the road of city gathering ground about 20%, 50% and 30% are respectively to the contribution of receiving water body suspension and hydrocarbon contamination; The U.S. about has the river of 60% relevant with non-point pollution with the lake pollution of 50%, realizes the city of secondary treatment, and water body BOD load is about 40%-80% from rainfall runoff; Road is very serious to the water pollution of periphery along the line; In rainwater on road surface runoff except containing heavy metal, hydrocarbon etc. to except the large pollutant of environmental hazard, the pollutants such as the oils that vehicle operating brings, the refuse that pedestrian abandons, the chip and pollutant etc. be washed into from garden and other open ground on street, finally all will migrate in water environment under rainwater drip washing, souring, and very large harm will be produced to these waters; Have the place of ecological responsive urban conservation area and important water conservation district at periphery, roadway pollutants more needs to take seriously to biological and diversity and water quality potential threat;
