Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the sponge urban ecological landscape road comprises a central green belt 4, a trunk road 1, a non-motor vehicle lane 2 and a sidewalk 3 which are symmetrically distributed on two sides of the central green belt 4, wherein a marginal green belt 4 is formed between the trunk road 1 and the non-motor vehicle lane 2 in an isolation manner; the bottom of the green belt 4 and the sidewalk 3 is paved with a drainage channel 5 and a reservoir 6, the drainage channel 5 is closely attached to the road and designed along the whole length of the road, a plurality of reservoirs 6 are arranged at the bottom of the same green belt 4 or the sidewalk 3 intermittently along the length direction of the road, and the reservoirs 6 are communicated with the top end of the drainage channel 5. When the rainy season comes, part of rainwater permeates into the ground from the road, and more accumulated water flows into the water storage tank 6 from the surface of the road for storage so as to be used for irrigating the green belt 4 in the arid season; when the reservoir 6 is full, the excess rainwater flows from the reservoir 6 into the drainage channel 5, and then the excess rainwater is drained from the drainage channel 5 to the outside.

Referring to fig. 1 and 2, the main road 1 and the non-motor vehicle road 2 are laid in the same structure, the main road 1 comprises a base soil layer 15, a cushion layer 14, a gravel layer 13, an emulsified asphalt permeable layer 12 and an asphalt concrete layer 11 which are laid in sequence from bottom to top, and the laying thickness of each layer meets the national standard or the industrial standard.

The edges of two sides of the main road 1 are inclined downwards by 15-20cm in an inclined way by 5-10 degrees so as to be beneficial to the accumulated water of the main road 1 to flow to the water reservoirs 6 at two sides of the road. The main road 1 of the non-motor vehicle lane 2 inclines downwards towards the sidewalk 3 in an inclined mode, and the inclined angle can be 2-5 degrees, so that accumulated water on the non-motor vehicle lane 2 can flow towards a water storage tank 6 at the bottom of the sidewalk 3.

Referring to fig. 2 and 3, the water reservoir 6 and the water drainage channel 5 are arranged side by side, a rain grate 10 is fixed between the top end of the water reservoir 6 and the road surface, a flow guide member 9 is fixed at the top of the water drainage channel 5, and the top surface of the flow guide member 9 is an inclined surface which is inclined downwards from the edge of the road surface to the water reservoir 6, so that the accumulated water on the road flows into the water reservoir 6 along the flow guide member 9 through the rain grate 10. The rain grate 10 can prevent sundries such as fallen leaves on a road from entering the water storage tank 6, the rain grate 10 is vertically fixed on the edge of the road, when part of the fallen leaves are blocked by the rain grate 10 and then can be stacked on the lower part of the rain grate 10, rainwater can still flow to the water storage tank 6 from holes in the upper part of the rain grate 10, and the possibility that the rain grate 10 is blocked by the sundries such as the fallen leaves is reduced.

Referring to fig. 4, at least one inflow opening 91 for communicating the water reservoir 6 with the drainage channel 5 is penetratingly provided on the inclined surface of the flow guide member 9, where the number of the inflow openings 91 may be 3-5, a fence 92 is fixed on the inclined surface at a side of each inflow opening 91 close to the rain grate 10, and the fence 92 may be curved, V-shaped, or the like, so that the water current on the flow guide member 9 bypasses the inflow openings 91 along the fence 92 to preferentially flow into the water reservoir 6, and when the water in the water reservoir 6 is accumulated until the water level reaches the inflow opening 91, the excessive rainwater flows into the drainage channel 5 through the inflow opening 91 and is drained.

Referring to fig. 3 and 4, an irrigation assembly 7 for watering vegetation in the green belt 4 is installed in the green belt 4, the irrigation assembly 7 comprises a water suction pump fixedly supported on the ground of the green belt 4, a water inlet pipe inserted into a water storage tank 6 is connected to a water inlet of the water suction pump, and an atomization nozzle is installed at a water outlet of the water suction pump through a water pipe. The water in the reservoir 6 is pumped to the water pipe by the water pump and sprayed to the green belt 4 from the atomizing nozzle, and the collected rainwater is fully utilized.

The green belt 4 is also provided with a sprinkling assembly 8 for spraying water to the road surface, and the difference between the sprinkling assembly 8 and the irrigation assembly 7 is that a spray head for a J008 type sprinkling vehicle on the market replaces an atomizing spray head, the spray head for the sprinkling vehicle is positioned 10-15cm above the edge of the road, and a spray nozzle of the spray head for the sprinkling vehicle faces the center of the road and is horizontally downwards inclined by 3-5 degrees. The water in the reservoir 6 is pumped to the water pipe by the water pump and is sprayed out from the spray head of the sprinkler at a high speed, so that the road surface can be washed and cooled in a dry season.

Referring to fig. 2, the sidewalk 3 is laid above the reservoir 6, and the sidewalk 3 can be formed by laying porous permeable bricks above the reinforcing mesh, which is beneficial for rainwater on the sidewalk 3 to directly seep into the reservoir 6. The number of the reservoirs 6 at the lower part of the sidewalk 3 is two, the bottoms of the two reservoirs 6 are communicated through the communication hole 61, and the water storage capacity of the two reservoirs 6 is increased. The water in the reservoir 6 at the bottom of the walkway 3 can be used for roadside park watering and fountain water.

The implementation principle of the sponge urban ecological landscape road is as follows: set up cistern 6 and drainage canal 5 under greenbelt 4 and pavement 3, through the water conservancy diversion piece 9 that sets up an inclined plane on drainage canal 5 for the rainwater flows to cistern 6 along road surface and water conservancy diversion piece 9 earlier, and after cistern 6 held full water, unnecessary rainwater was again through the inflow entrance 91 on the water conservancy diversion piece 9 with ponding drainage canal 5, can also have good anti flood ability when the rainwater was collected in the preferential guarantee. According to needs, the water in the water storage tank 6 can be used for irrigating green plants in the green belt 4 through the irrigation assembly 7, and the road surface can be cleaned and dedusted through the sprinkling assembly 8 in the green belt 4.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
