Abstract

The invention discloses a green belt with an initial rainwater road surface runoff purifying function and the water storage function and relates to the technical field of surface source pollution control. Pebbles or gravel is laid on the portion, lower than the road surface, at the bottom of the green belt. The pebbles or the gravel is covered with sand to form a water storage layer (5). Soil used for planting plants is laid on the sand. A curb (1) is arranged on the side, towards a road, of the green belt. Water passing holes (2) provided with filtering screens (3) are formed in the curb and incline to the green belt, and the bottoms of the water passing holes (2) are slightly lower than the road surface. A seepage ditch (4) is built between the curb and the soil and is communicated with the water storage layer (5). Pebbles or gravel is placed in the seepage ditch (4), and plants strong in vitality and resistant to flooding and pollution are planted on the soil to form green land (6). The green belt has the advantages that initial rainwater is absorbed, high-concentration pollutants, directly entering a municipal gutter inlet (7), in initial rainwater road surface runoff are reduced, rainwater is stored, and the amount of water used for irrigating the green land is reduced.

Description

A kind of greenbelt with purifying rainwater Road surface Initial runoff and water storage function
Technical field
The invention belongs to field of surface source pollution control technology, be specifically related to a kind of greenbelt with purifying rainwater Road surface Initial runoff and water storage function, be applicable to the Road surface Initial runoff processing road at different levels, a small amount of high-concentration sewage that cleaning road surface, daily sprinkling truck produces can be processed simultaneously.
Background technology
At present, most of municipal sewage pipe network carries out rain dirt shunting, and pavement runoff collects process through Storm Sewer Network.Road surface Initial runoff pollution concentration is high, and its pollution loading amount accounts for the absolute number value of time rainfall gross contamination load, is the important sources of water environment pollution.Along with the increase of amount of precipitation, road surface amount of pollutants reduces, pollutant levels reduce, and the degree of contamination of pavement runoff to environment alleviates thereupon greatly.Therefore, it is a kind of from Sources controlling pavement runoff and pollution of area source, cost-effective kind of Best Management Practices for processing Road surface Initial runoff.
The main purpose of road green belt is protection traffic safety, environment purification and beautifying city.Road green belt common at present generally exceeds road surface, and closed road kerb is concordant with greenery patches, not only can not cut down pavement runoff, and the runoff in greenbelt also easy overflow enters inlet for stom water, increases the pollution load of pavement runoff and the discharge pressure of municipal Storm Sewer Network.Therefore, be necessary to propose a kind of effective ways making full use of road green belt, focus on high concentration Road surface Initial runoff.
Summary of the invention
The object of the invention is, a kind of greenbelt with purifying rainwater Road surface Initial runoff and water storage function is provided, this greenbelt improves relative less with Road surface Initial runoff pollution amount, that relative concentration is high feature day by day for existing road landscape planting rate, the pavement runoff treatment system reducing pollutant based on landscape green space is provided, and can retaining, to reduce the water supply volume in pouring greenery patches.
In order to achieve the above object, the present invention adopts following technical scheme:
There is a greenbelt for purifying rainwater Road surface Initial runoff and water storage function, it is characterized in that: this greenbelt comprises road kerb, water hole, filter screen, infiltration ditch, reservoir bed and greenery patches, greenbelt is placed in centre or the both sides of road, lay cobble or the gravel of 15 ~ 20 centimetres lower than road surface 30 ~ 40 centimeters bottom greenbelt, cobble or gravel cover the sand of 2 ~ 3 cm thicks, cobble or gravel and sand form reservoir bed, sand is laid the earth being used for planting plants, road kerb is placed in the face of road side at greenbelt, road kerb is arranged the water hole of band filter screen, water hole tilts to greenbelt, bottom is a little less than the road surface of road, the infiltration ditch of 5 ~ 10 centimetres wide is built between road kerb and earth, infiltration ditch communicates with reservoir bed, cobble or gravel is placed in infiltration ditch, earth is planted vitality strong, the resistance to plant flooding resistant is greenery patches.
Compared with existing greenbelt, advantage of the present invention is: receive early-stage rainwater, reduces the high density pollution thing directly entered in municipal inlet for stom water Road surface Initial runoff; Savings rainwater, reduces the water supply volume in pouring greenery patches.
Accompanying drawing explanation
Fig. 1 is a kind of sectional drawing with the greenbelt of purifying rainwater Road surface Initial runoff and water storage function.
Wherein: 1 is road kerb, 2 is water hole, and 3 is filter screen, and 4 is infiltration ditch, and 5 is reservoir bed, and 6 is greenery patches, and 7 is municipal inlet for stom water.
Fig. 2 is a kind of sectional view with the greenbelt of purifying rainwater Road surface Initial runoff and water storage function.
Wherein: 1 is road kerb, 2 is water hole, and 3 is filter screen, and 4 is infiltration ditch, and 5 is reservoir bed, and 6 is greenery patches, and 7 is municipal inlet for stom water.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Have a greenbelt for purifying rainwater Road surface Initial runoff and water storage function, this greenbelt comprises road kerb 1, water hole 2, filter screen 3, infiltration ditch 4, reservoir bed 5 and greenery patches 6, greenbelt is placed in centre or the both sides of road, cobble or gravel is laid lower than road surface place bottom greenbelt, cobble or gravel cover sand, cobble or gravel and sand form reservoir bed 5, sand is laid the earth being used for planting plants, road kerb 1 is placed in the face of road side at greenbelt, road kerb is arranged the water hole 2 of band filter screen 3, water hole 2 tilts to greenbelt, bottom is a little less than the road surface of road, infiltration ditch 4 is built between road kerb and earth, infiltration ditch 4 communicates with reservoir bed 5, cobble or gravel is placed in infiltration ditch 4, earth is planted vitality strong, the resistance to plant flooding resistant is greenery patches 6.
The bottom of above-mentioned greenbelt lower than 30 ~ 40 centimetres, road surface, lay cobble or gravel thickness be 15 ~ 20 centimetres, cover sand thickness be 2 ~ 3 centimetres.
The width of above-mentioned infiltration ditch (4) is 5 ~ 10 centimetres.
Effect of the present invention is: the water hole 2 of Road surface Initial runoff on road kerb 1 that rain confluxes from high to low naturally into greenbelt, rubbish etc. in filter screen 3 road pavement runoff on water hole tentatively filters, through infiltration ditch 4 permeate, cushion after enter reservoir bed 5, penetrate into greenery patches 6 again, through processes such as plant absorption and soil filtrations in greenery patches 6, permeate and purify pavement runoff.In the rainfall middle and later periods, when greenery patches 6 intake concordant with road surface close to saturated, water level after, runoff enters greenbelt and is obstructed, then unnecessary runoff automatically enters municipal inlet for stom water 7 and collects through Storm Sewer Network.
