Abstract
Description
Technical Field
[0001] This utility model relates to the field of bioretention strip technology, and in particular to a bioretention strip for municipal roads in sponge cities. Background Technology
[0002] Chinese Patent CN217517752U discloses a bioretention strip for municipal roads in sponge cities. In this bioretention strip, rainwater enters the inner cavity of the bioretention frame and is filtered by a second mesh plate to remove debris such as garbage and fallen leaves. A water pump is activated to draw in rainwater and spray it upwards, thus wetting the soil layer and replenishing the water for the biological plants. Simultaneously, a forward and reverse motor drives a screw nut to periodically move left and right, which, combined with the expandable and deformable material of the telescopic water pipe, moves the nozzles left and right, fully wetting the soil layer at different locations, improving the water replenishment effect for the biological plants, reducing the labor intensity and workload of workers, facilitating rainwater recycling, and increasing energy efficiency. However, this bioretention strip for municipal roads in sponge cities, while solving the problem, has the drawback of not considering that roads in sponge cities can store more rainwater, and that the stored rainwater can be used for the maintenance of green belts along municipal roads. Therefore, this utility model designs a bioretention strip for municipal roads in sponge cities. Utility Model Content
[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0004] Therefore, one objective of this utility model is to propose a bio-retention strip for municipal roads in sponge cities, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0005] To achieve the above objectives, one embodiment of this utility model provides a bioretention strip for municipal roads in sponge cities, comprising a road, an internal regulating water tank, a green belt fixedly connected to one side of the road, three ecological tree pits inside the green belt, each ecological tree pit having an overflow outlet, a regulating drainage pipe fixedly connected to the interior of the road, six drainage pipes fixedly connected to the outer surface of the regulating drainage pipe, a watering pipe fixedly connected to the interior of each ecological tree pit, trees planted inside each ecological tree pit, several small grasses planted on one side of the green belt, and permeable cement concrete fixedly connected to one side of the road.
[0006] Preferably, in any of the above schemes, the interior of the three drainage pipes is connected to the interior of the regulating water tank.
[0007] Preferably, in any of the above schemes, the interior of the other three drainage pipes is connected to the interior of the corresponding ecological tree pool.
[0008] The technical effect achieved by adopting the above solution is that it enables the water inside the regulating reservoir and the ecological tree pool to circulate, making it convenient to adjust the water level inside the regulating reservoir and the ecological tree pool.
[0009] Preferably, in any of the above schemes, a water pump is fixedly connected to the outer surface of each watering pipe.
[0010] Preferably, each of the above-mentioned schemes has an atomizing nozzle fixedly connected to the top of each watering pipe.
[0011] The technical effect achieved by adopting the above solution is that the water inside the ecological tree pool enters the atomizing nozzle through the watering pipe and water pump, and then the water is sprayed onto the surface of the green belt through the atomizing nozzle, which facilitates the use of the water inside the ecological tree pool to maintain the green belt.
[0012] Preferably, one side of the road is fixedly connected to a curb, and the curb has several through cavities inside.
[0013] Preferably, in any of the above schemes, the height of the road is higher than the height of the green belt.
[0014] The technical effect achieved by adopting the above solution is that it enables a large amount of rainwater to enter the green belt through the cavity and then permeate into the ecological tree pool 4, thus avoiding the problem of excessive rainwater accumulation on the road and blockage of the sewer.
[0015] Preferably, one side of the road is fixedly connected to a drain pipe.
[0016] The technical effect achieved by adopting the above solution is that this utility model has the function of regulating the water level inside the water storage tank, thus avoiding excessive water pressure and damage to the road.
[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0018] 1. This device is equipped with a regulating drainage pipe. When both the ecological tree pit and the regulating water tank are filled with water, if the water level in the ecological tree pit is higher than the overflow outlet, water will flow into the regulating water tank through the drainage pipe and the regulating drainage pipe. If the water level in the ecological tree pit is lower than the overflow outlet, water from the regulating water tank can flow into the ecological tree pit through the drainage pipe and the regulating drainage pipe. The regulating drainage pipe facilitates the adjustment of the water levels in the ecological tree pit and the regulating water tank, and discharges excess water from the regulating water tank through the sewer pipe. This helps prevent excessive water pressure in the ecological tree pit and the regulating water tank, which could cause multiple gaps in the green belt and road, and helps extend the service life of the road and the green belt.
[0019] 2. This device is equipped with a water pump. When it is not raining, the water pump draws rainwater stored inside the ecological tree pool through the water pipe and water pipe, and then waters the surface of the trees and grass through the misting nozzles. This ensures that the green plants on the surface of the green belt are fully moisturized, which reduces the number of times the municipal water supply is needed to irrigate the green belt. It is conducive to the recycling of water resources and helps to maintain the green belt while saving water resources.
[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] like Figures 1 to 4 As shown, a bioretention strip for sponge city municipal roads includes a road 1, which is part of a sponge city municipal road. A regulating water storage tank 2 is located inside the road 1. Because the top of the road 1 is paved with permeable cement concrete 16, rainwater permeates the permeable cement concrete 16 and reaches the interior of the regulating water storage tank 2 during rainfall. A green belt 3 is fixedly connected to one side of the road 1. Three ecological tree pits 4 are located inside the green belt 3. During rainfall, rainwater permeates into the soil and then enters the interior of the ecological tree pits 4. Each ecological tree pit 4 has an overflow outlet 5. When both the ecological tree pit 4 and the regulating water storage tank 2 are filled with water, if the water level in the ecological tree pit 4 is higher than the overflow outlet 5, the water enters the regulating water storage tank 2 through a drainage pipe 7 and a regulating drainage pipe 6. When the water level inside the ecological tree pool 4 is lower than the overflow outlet 5, the water inside the regulating reservoir 2 can enter the interior of the ecological tree pool 4 through the drainage pipe 7 and the regulating drainage pipe 6. The regulating drainage pipe 6 is fixedly connected inside the road 1, and six drainage pipes 7 are fixedly connected to the outer surface of the regulating drainage pipe 6. A watering pipe 8 is fixedly connected inside each ecological tree pool 4. The watering pipe 8 draws water from the interior of the ecological tree pool 4 through the water pump 9 and waters the surface of the trees and grass through the atomizing nozzle 10. Trees 11 are planted inside each ecological tree pool 4. Several grasses 12 are planted on one side of the green belt 3. Permeable cement concrete 16 is fixedly connected to one side of the road 1. The permeable cement concrete 16 allows rainwater or water sprayed on the road by the sprinkler truck to seep into the regulating reservoir 2.
[0030] The interiors of three drainage pipes 7 are connected to the interior of the regulating reservoir 2.
[0031] The interiors of the other three drainage pipes 7 are connected to the interiors of the corresponding ecological tree pools 4.
[0032] A water pump 9 is fixedly connected to the outer surface of each watering pipe 8.
[0033] Each watering pipe 8 is fixedly connected to a misting nozzle 10 at its top (the misting nozzle 10 is a known technology).
[0034] A curb 13 is fixedly connected to one side of the road 1. Several cavities 14 are opened inside the curb 13. When it rains heavily, the rainwater infiltration speed is too slow. The height of the green belt 3 is lower than the height of the road 1. Most of the rainwater is discharged into the top of the green belt 3 through the cavities 14.
[0035] The height of road 1 is higher than the height of green belt 3, and the green belt adopts a sunken green space (sunken green space is a known technology).
[0036] A sewer pipe 15 is fixedly connected to one side of the road 1. When the water level inside the regulating reservoir 2 reaches the height of the sewer pipe 15, it enters the city drainage pipe through the sewer pipe 15.
[0037] The working principle of a bioretention strip for municipal roads in sponge cities is as follows:
[0038] 1) When it rains, rainwater drips onto the surface of the permeable cement concrete 16. When the rainfall is small, it directly enters the interior of the regulating water tank 2 through the permeable cement concrete 16. When the rainfall is large, the rainwater infiltration speed is too slow, and most of the rainwater is discharged into the top of the green belt 3 through the cavity 14. The rainwater nourishes the roots of the trees and grass and then flows into the interior of the ecological tree pool 4.
[0039] 2) When both the ecological tree pool 4 and the regulating water tank 2 are filled with water, if the water level in the ecological tree pool 4 is higher than the overflow outlet 5, the water will enter the regulating water tank 2 through the drain pipe 7 and the regulating drainage pipe 6. If the water level in the ecological tree pool 4 is lower than the overflow outlet 5, the water in the regulating water tank 2 can enter the ecological tree pool 4 through the drain pipe 7 and the regulating drainage pipe 6. If the water level in the regulating water tank 2 reaches the height of the sewer pipe 15, the water will enter the urban drainage pipe through the sewer pipe 15 until the water level drops below the sewer pipe 15.
[0040] 3) When it is not raining, rainwater stored inside the ecological tree pool 4 is drawn through the watering pipe 8 and the water pump 9, and then watered on the surface of the trees and grass through the atomizing nozzle 10.
[0041] Compared with the prior art, the present invention has the following advantages:
[0042] 1. This device is equipped with a regulating drainage pipe 6. When both the ecological tree pool 4 and the regulating water tank 2 are filled with water, if the water level in the ecological tree pool 4 is higher than the overflow outlet 5, the water will enter the regulating water tank 2 through the drainage pipe 7 and the regulating drainage pipe 6. If the water level in the ecological tree pool 4 is lower than the overflow outlet 5, the water in the regulating water tank 2 can enter the ecological tree pool 4 through the drainage pipe 7 and the regulating drainage pipe 6. The regulating drainage pipe 6 facilitates the adjustment of the water levels in the ecological tree pool 4 and the regulating water tank 2, and discharges excess water from the regulating water tank 2 through the drain pipe 15. This helps prevent excessive water pressure in the ecological tree pool 4 and the regulating water tank 2, which could cause multiple gaps in the green belt 3 and the road 1, and thus enhances the service life of the road 1 and the green belt 3.
[0043] 2. This device is equipped with a water pump 9. When it is not raining, the rainwater stored inside the ecological tree pool 4 is drawn through the watering pipe 8 and the water pump 9, and then watered through the misting nozzle 10 to irrigate the surface of the trees and grass, so that the green plants on the surface of the green belt are fully moistened. This reduces the number of times the municipal water supply is needed to irrigate the green belt, which is conducive to the recycling of water resources and facilitates the maintenance of the green belt while saving water resources.
