As a further improvement on the present invention, the filtration include be sequentially arranged from top to bottom permeable dielectric layer, Loaded filter, gravel layer, for realizing that naturally osmotic is purified.
As a further improvement on the present invention, second flow guiding structure is perforation water-permeable pipe, and it is located at filtration Bottom, the water for getting off is permeated in undertaking filtration.
As a further improvement on the present invention, second flow guiding structure is located in gravel layer, for excluding greening groove bottom Portion's rainwater.
As a further improvement on the present invention, the soil permeability of the permeable dielectric layer is not less than 100mm/ hours, by Sand and the uniform mix of planting soil, preferably by 40% medium coarse sand, 40% planting soil and the 20% uniform mixs of coconut palm Kang, the content of organic matter meets Apolegamy demand of plant growth.
As a further improvement on the present invention, first flow guiding structure includes at least one pipeline.
As a further improvement on the present invention, the gutter top sets grille mesh cover and rain grid capping, is used for Intercept bridge floor debris.
As a further improvement on the present invention, the close side roof part of catch basin one of the greening groove sets discharge opening, for inciting somebody to action Exceeded rainwater is incorporated into catch basin in greening groove.
As a further improvement on the present invention, the water plug is suction pump, and suction pump is also associated with sprinkler tip, is stored In tank after the rainwater of purification is through pumped of drawing water, vegetation is poured by sprinkler tip.
As a further improvement on the present invention, the catch basin top sets overflow pipe, overflow pipe and vertical drainage Pipe is connected, for excluding the rainfall later stage exceeded rainwater of bridge floor(It is directly discharged under bridge), the elevation of overflow pipe must be less than sluicing Mouth elevation.
Beneficial effects of the present invention:
1. greening groove being set outside guardrail can not only store deck runoff rainwater, and deck runoff pollution can also be filtered Purification punishment.
2. rainwater is oozed under after the setting perforation water-permeable pipe in greening trench bottom gravel layer can be purified with drainage.
3. when rainfall is larger, rainwater is emitted into catch basin by discharge opening in greening groove.
4. the rainwater in catch basin after purification can be used for vegetation and irrigate through pumped of drawing water by sprinkler tip.
5. catch basin can carry out interim storage delay, when water level is higher than catch basin overflow pipe, exceeded rainwater to rainwater Discharged by overflow pipe.
