Background
With the rapid development of urbanization, urban municipal facilities such as squares, roads and the like constructed by waterproof materials such as stone, cement, concrete and the like are covered by waterproof asphalt concrete layers with large areas on the original natural permeable underlying surface, so that rainfall runoff generated on the underlying surface of the city is difficult to seep during rainfall, the time for forming a flood peak is advanced, and urban ponding waterlogging disasters are easily caused. The proportion of the road surface in the waterproof underlying surface of the urban area is high, the rainfall runoff generated on the surface of the road surface is also large, the accumulated water generated on the road surface influences traffic, inconvenience is brought to people going out, and meanwhile the urban waterlogging risk is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough of prior art, provide a sponge city ecological road roadbed structure, concrete scheme is as follows:
a sponge urban ecological road subgrade structure comprises a road and green belts arranged on two sides of the road; the road sequentially comprises a permeable asphalt concrete layer, a slag soil layer, a first permeable concrete layer, a water storage layer and a tamping roadbed from top to bottom, wherein an aggregate layer is pressed on the surface of the tamping roadbed, a supporting plate for supporting the first permeable concrete layer is arranged on the aggregate layer, the extending direction of the supporting plate is consistent with the extending direction of the road, and a notch is formed in the bottom of the supporting plate; the green belt comprises a water-impermeable groove, a vegetable layer, a soil layer, a fine sand layer, a residue soil layer, a second water-permeable concrete layer and a water storage tank are sequentially arranged in the water-impermeable groove from top to bottom, a water diversion rope extending to the soil layer is arranged in the water storage tank, a water outlet communicated with the water storage tank and the water storage layer is formed in the side wall of the water-impermeable groove, and a filter screen is arranged at the water outlet.
On the basis, the two sides of the permeable asphalt concrete layer are provided with drainage grooves, and the upper surfaces of the drainage grooves are paved with grids.
Based on the above, the compacted roadbed and the aggregate layer on the surface of the compacted roadbed have the tendency of high middle and low two sides.
Based on the above, the first water-permeable concrete layer is formed by splicing precast slabs.
The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:
1. the utility model discloses in, the structural design of road makes the rainwater can be discharged to secret infiltration or through water drainage tank fast, effectively avoids the emergence of surface gathered water phenomenon.
2. The utility model discloses in, the structural design of greenbelt not only can make the rainwater permeate downwards fast, but also can carry out an amount of storage to the rainwater, plays the effect of using water wisely.
3. The utility model discloses in, the structural design of water-storage layer plays certain buffering effect to the rainwater infiltration in-process.
4. The utility model discloses in, the water drainage tank design of road both sides makes near water drainage tank's water discharge fast, leads to the road intermediate position infiltration volume relatively great, so will tamp road bed and surperficial aggregate layer design for be middle high, the low trend in both sides for the water of infiltration water-storage layer flows to both sides, plays a balance effect, also accelerates the infiltration speed simultaneously.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. a road; 2. a green belt; 3. a pervious asphalt concrete layer; 4. a crushed stone layer; 5. a first pervious concrete layer; 6. a aquifer; 7. a support plate; 8. a notch; 9. an aggregate; 10. a water discharge tank; 11. a grid; 12. a water impermeable tank; 13. a vegetable layer; 14. a soil layer; 15. a fine sand layer; 16. a slag soil layer; 17. a second pervious concrete layer; 18. a water storage tank; 19. a water diversion rope; 20. a water outlet; 21. a filter screen; 22. and (5) compacting the roadbed.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Examples
As shown in figure 1, the utility model provides a sponge city ecological road roadbed structure, including road 1 and the greenbelt 2 of setting in road 1 both sides.
Above-mentioned road 1 is from last down to be pervious to water asphalt concrete layer 3, metalling 4, the first pervious to water concrete layer 5, water-storage layer 6 and tamped road bed 22 in proper order, tamped road bed 22 surface pressure is equipped with aggregate 9 layer, be equipped with the support on the aggregate 9 layer the backup pad 7 of the first pervious to water concrete layer 5, the extending direction of backup pad 7 is unanimous with the 1 extending direction of road, and breach 8 is seted up to the bottom of backup pad 7.
The green belt 2 comprises a water-impermeable groove 12, a vegetation layer 13, a soil layer 14, a fine sand layer 15, a residue soil layer 16, a second water-permeable concrete layer 17 and a water storage groove 18 are sequentially arranged in the water-impermeable groove 12 from top to bottom, and a water guide rope 19 extending to the soil layer 14 is arranged in the water storage groove 18.
In order to facilitate the water in the water storage tank 18 to be discharged outwards, a water discharge port 20 communicating the water storage tank 18 and the water storage layer 6 is arranged on the side wall of the water-tight tank 12, and a filter screen 21 is arranged at the water discharge port 20.
Considering that water on the road 1 cannot penetrate downwards in time under the condition of too fast rainfall speed, drainage grooves 10 are arranged on two sides of the permeable asphalt concrete layer 3, and a grid 11 is laid on the upper surfaces of the drainage grooves 10.
Because the design of the water tanks on the two sides of the road 1 enables water near the water tanks to be quickly discharged, the water seepage amount at the middle position of the road 1 is relatively large, the rammed roadbed 22 and the aggregate 9 layers on the surface of the rammed roadbed are designed to have the tendency of high in the middle and low on the two sides, so that the water permeating into the water storage layer 6 flows to the two sides, a balance effect is achieved, and the water seepage speed is accelerated.
It should be noted that, in order to facilitate the laying of the first pervious concrete layer 5, the first pervious concrete layer 5 is formed by splicing prefabricated plates.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
