Cinder permeable formation 23 permeates up rainwater, meanwhile, boulder bed 24 is designed with to certain gradient, to away from sump 11
Tilted with the side of screened well 12, this ensure that rainwater can be penetrated into fully in the greenbelt under whole bridge；Oozed in cinder
The top of permeable layers 23 sets one layer of mud to isolate geotextiles 22, can effectively prevent from gushing on mud permeable while, final to ensure to ooze
Meet to irrigate to the rainwater in planting soil layer 21 thoroughly and require.
The course of work of the present utility model is：
Rainwater on viaduct pier cushion cap 1 is flowed into sump 11 by rainwater collection collector 4, treats rainwater-collecting to one
Rainwater runs past filter bores 6 and flowed into screened well 12 when quantitative, and the rainwater flowed into screened well 12 passes through the first screen pack again
13.1st, the second screen pack 13.2 and the 3rd screen pack 13.3 be flowed into it is anti-under ooze green plants carried out in greenbelt plantation layer 20
Pour, when bridge floor amount of rainfall is excessive, more than during greenbelt ability to arrange jobs, unnecessary rainwater then passes through overflow pipe 30 and flows into row under bridge
In well 31, it is discharged to finally by branch drain 32 in urban road drainage pipeline.To ensure landscape effect, the top of gully 31
It should not expose and greenbelt plantation layer 20 is oozed under preventing, the length of overflow pipe 30 should combine the vegetation type of greenbelt under overpass and prevent
Under ooze greenbelt plantation layer 20 water-holding capacity consider.
Compared with existing greenbelt rainwater utilization system, the utility model will be collected into rainwater by sump 11 and filtering
After the multistage filtering and precipitation of well 12, debris has been substantially removed in rainwater, and harmful substance contents are greatly reduced, and is fully met
To the watering requirement of greenbelt plant under bridge, ensure that plant being capable of healthy growth in greenbelt；It is arranged on sump 11, screened well
Removable cover on 12, it can periodically open removable cover and carry out artificial desilting, construction operation is i.e. convenient and safe, this
Outside, the advantages of the utility model also has i.e. ecology and environmentally friendly, and without any electric power facility, and construction and maintenance cost are low.
The part not illustrated in specification is prior art or common knowledge.It is new that the present embodiment is merely to illustrate the practicality
Type, rather than limitation the scope of the utility model, the equivalent replacement that those skilled in the art are done for the utility model etc.
