Description

Technical Field

[0001] The utility model relates to the technical field of road rainwater utilization, in particular to an urban road with a rainwater utilization function. Background Art

[0002] Urban roads are roads that connect various areas of the city, provide transportation and pedestrian use within the city, facilitate residents' lives, work, cultural and entertainment activities, and connect with roads outside the city to carry external traffic. With the development of sponge cities, people have begun to collect and utilize rainwater on urban roads to alleviate the pressure of irrigation water for road green belts.

[0003] The patent with announcement number CN206266977U discloses "an integral large-cavity bottom trough for collecting rainwater on urban roads. Permeable concrete cover plates are used on the sidewalk pavements on both sides of the urban roads to form a temporary water storage and drainage layer with the integral large-cavity bottom trough. The beneficial effects of the utility model are simple structure, good force performance, and easy processing. The road rainwater collection and drainage system can effectively solve the problem of easy water accumulation on existing roads. A large number of quick-collection temporary water storage cavities can quickly collect and store water through permeable holes, and through long-term infiltration and purification over a period of time, efficient rainwater utilization and disaster prevention are achieved."

[0004] With regard to the above-mentioned related technologies, the inventor believes that as rainwater washes the road surface, the rainwater flowing into the road rainwater collection well will contain a certain amount of sediment. The rainwater containing sediment will flow into the temporary storage layer for road rainwater collection through the drainage pipe. After long-term use, as the sediment accumulates, the water storage capacity of the temporary storage layer for road rainwater collection will deteriorate. Due to the obstruction of the concrete slabs in the storage layer, it is inconvenient to clean the sediment in the temporary storage layer for road rainwater collection, so it needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an urban road with rainwater utilization function. The specific technical solution is as follows:

[0006] An urban road with rainwater utilization function comprises a roadbed, a rainwater collecting culvert pre-buried in the roadbed, a permeable sidewalk surface arranged on the top of the roadbed and used to discharge rainwater from the road surface into the rainwater collecting culvert, and a road rainwater collecting well arranged on the top of the roadbed and used to replenish water to the rainwater collecting culvert, wherein a top plate is fixedly arranged on the top of the inner wall of the rainwater collecting culvert, two groups of symmetrically distributed reinforcing rods are fixedly arranged between the bottom of the top plate and the bottom of the inner wall of the rainwater collecting culvert, a plurality of drainage holes are opened between the top plate and the top of the rainwater collecting culvert, a sediment pump for extracting sediment and water to irrigate surrounding green plants is fixedly arranged on the bottom of the inner wall of the rainwater collecting culvert, and an indicating mechanism for indicating the water level in the rainwater collecting culvert to people is arranged on the top of the roadbed.

[0007] By adopting the above technical scheme, the middle part of the rain-collecting culvert can be strengthened by reinforcing rods and top plates, and the reinforcing rods have a smaller shielding range for silt, which makes it easier for the silt pump to extract the silt deposited at the bottom of the rain-collecting culvert. The silt pump can also extract the rainwater collected in the rain-collecting culvert to be used as irrigation water for surrounding green plants.

[0008] Optionally, the indicating mechanism includes a floating plate arranged inside the rain-collecting culvert, and a square rod fixed on the top of the floating plate and with the top end penetrating through and extending to the outside of the roadbed. An indicating sign is fixed on the top of the square rod for people to observe conveniently, and a roller is rotatably provided on one side of the square rod for cooperating and abutting against the inner wall of the rain-collecting culvert.

[0009] By adopting the above technical solution, through the buoyancy of the floating plate caused by rainwater in the rainwater collecting culvert and the connection of the square rods, the signboard can be raised and lowered with the water level in the rainwater collecting culvert, making it convenient for people to decide the amount of irrigation for the surrounding green plants by observing the water level on the road.

[0010] Optionally, a water inlet pipe is fixedly provided between one side of the rainwater collecting culvert and the inner wall of the road rainwater collecting well, and a water inlet grate for filtering rainwater is provided on the top of the inner wall of the road rainwater collecting well.

[0011] By adopting the above technical solution, excess rainwater in the road rainwater collection well will flow into the rainwater collecting culvert through the water inlet pipe to replenish water in the rainwater collecting culvert.

[0012] Optionally, a municipal pipeline is pre-buried in the roadbed, and a drainage pipe is fixedly provided between the side of the rainwater collecting culvert away from the road rainwater collection well and the top of the municipal pipeline.

[0013] By adopting the above technical solution, excess rainwater in the rainwater collecting culvert will be discharged into the municipal pipeline through the drainage pipe, and then sent to the external rainwater treatment equipment by the municipal pipeline for subsequent treatment.

[0014] In summary, the present invention has at least one of the following beneficial effects:

[0015] 1. The middle part of the rainwater collecting culvert can be strengthened by reinforcing rods and top plates, and the reinforcing rods have a smaller shielding range for silt, which makes it easier for the silt pump to extract the silt deposited at the bottom of the rainwater collecting culvert, making cleaning more convenient. The rainwater collecting culvert can collect rainwater discharged from the road surface and sent into the road rainwater collection well. The silt pump can also extract the rainwater collected in the rainwater collecting culvert to use as irrigation water for surrounding green plants, thereby collecting and utilizing rainwater and improving the utilization rate of resources.

[0016] 2. Through the buoyancy of the floating plate by rainwater in the rainwater collecting culvert and the connection of the square rod, the signboard can be raised and lowered with the water level in the rainwater collecting culvert, so that people can decide the amount of irrigation for the surrounding green plants by observing the water level on the road surface. The operation is convenient. The roller can limit the floating plate so that the floating plate is not easy to swing, and the roller can reduce the resistance of the floating plate when it is raised and lowered by rotating.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model embodiment discloses an urban road with rainwater utilization function, referring to Figure 1 , including a roadbed 1, a rainwater collecting culvert 2 pre-buried in the roadbed 1, a permeable sidewalk pavement 3 provided on the top of the roadbed 1 and used to discharge rainwater from the road surface into the rainwater collecting culvert 2, and a road rainwater collection well 5 provided on the top of the roadbed 1 and used to replenish water to the rainwater collecting culvert 2. The rainwater collecting culvert 2 can be prefabricated with reinforced concrete, and the permeable sidewalk pavement 3 can be composed of a crushed stone layer, a sand and gravel layer and a permeable brick layer laid in sequence from bottom to top, wherein the permeable sidewalk pavement 3 is a public technology and will not be described in detail here. The road rainwater collection well 5 can collect rainwater flowing down from the surrounding roads.

[0023] Reference Figure 1 A top plate 21 is fixedly provided on the top of the inner wall of the rain-collecting culvert 2, and two groups of symmetrically distributed reinforcing rods 22 are fixedly provided between the bottom of the top plate 21 and the bottom of the inner wall of the rain-collecting culvert 2. The two groups of symmetrically distributed reinforcing rods 22 form an "X" shape and are located in the middle of the inner side of the rain-collecting culvert 2. The two groups of reinforcing rods 22 can reinforce the middle part of the rain-collecting culvert 2, and the reinforcing rods 22 cooperate with the top plate 21 to support the top of the rain-collecting culvert 2 more evenly, thereby improving the bearing capacity of the top of the rain-collecting culvert 2.

[0024] Reference Figure 1-2 A plurality of drainage holes 23 are provided between the top plate 21 and the top of the rainwater collecting culvert 2 . Rainwater flowing down from the permeable pavement 3 of the sidewalk will flow into the bottom of the inner side of the rainwater collecting culvert 2 through the drainage holes 23 , and the rainwater will be collected by the rainwater collecting culvert 2 .

[0025] Reference Figure 1 A water inlet pipe 51 is fixedly provided between one side of the rainwater collecting culvert 2 and the inner wall of the road rainwater collecting well 5. A water inlet grate 52 for filtering rainwater is provided on the top of the inner wall of the road rainwater collecting well 5. Excess rainwater in the road rainwater collecting well 5 will flow into the rainwater collecting culvert 2 through the water inlet pipe 51 to replenish water in the rainwater collecting culvert 2. The water inlet grate 52 can filter the rainwater entering the road rainwater collecting well 5 and block larger foreign objects such as leaves.

[0026] Reference Figure 1 A sediment pump 24 for extracting sediment and pumping water to irrigate surrounding green plants is fixedly provided at the bottom of the inner wall of the rain-collecting culvert 2. The sediment pump 24 can extract the sediment deposited in the rain-collecting culvert 2 to clean the rain-collecting culvert 2. When extracting sediment, since the contact area between the bottom end of the reinforcing rod 22 and the inner bottom of the rain-collecting culvert 2 is small, the reinforcing rod 22 is not easy to block the sediment, thereby making it easier to extract the sediment at the inner bottom of the rain-collecting culvert 2.

[0027] Reference Figure 1 A municipal pipeline 6 is pre-buried in the roadbed 1, and a drainage pipe 61 is fixedly arranged between the side of the rainwater collecting culvert 2 away from the road rainwater collection well 5 and the top of the municipal pipeline 6. Excess rainwater in the rainwater collecting culvert 2 will be discharged into the municipal pipeline 6 through the drainage pipe 61, and then sent to the external rainwater treatment equipment by the municipal pipeline 6 for subsequent treatment.

[0028] Reference Figure 1-3 An indicating mechanism for indicating the water level in the rain-collecting culvert 2 to people is provided on the top of the roadbed 1. The indicating mechanism includes a floating plate 4 arranged inside the rain-collecting culvert 2, and a square rod 41 fixed on the top of the floating plate 4 and with the top end penetrating and extending to the outside of the roadbed 1. A sealing member can be provided at the connection between the square rod 41 and the rain-collecting culvert 2. The rain-collecting culvert 2 and other components can also limit the square rod 41, so that the square rod 41 can be lifted and moved but cannot be rotated. The floating plate 4 will rise and fall with the water level in the rain-collecting culvert 2 under the buoyancy.

[0029] Reference Figure 1 and Figure 3 A signboard 42 is fixedly provided on the top of the square rod 41 for people to observe conveniently. The square rod 41 can connect the floating plate 4 and the signboard 42, so that the signboard 42 can also rise and fall with the water level in the rainwater collecting culvert 2, thereby indicating the water level of the rainwater collecting culvert 2 to people on the road.

[0030] Reference Figure 1 and Figure 3 A roller 43 that cooperates and abuts against the inner wall of the rain-collecting culvert 2 is rotatably provided on one side of the square rod 41. The roller 43 abutting against the inner wall of the rain-collecting culvert 2 can limit the floating plate 4, so that the floating plate 4 is not easy to swing with the water in the rain-collecting culvert 2, and the roller 43 can reduce the resistance of the floating plate 4 when it is raised and lowered by rotating.

[0031] The implementation principle of an urban road with rainwater utilization function in the embodiment of the utility model is:

[0032] When it rains, rainwater flowing down the permeable pavement 3 of the sidewalk will flow into the inner bottom of the rainwater collecting culvert 2 through the drainage hole 23, and the rainwater will be collected by the rainwater collecting culvert 2. Rainwater flowing down the surrounding roads will enter the road rainwater collecting well 5. Excessive rainwater in the road rainwater collecting well 5 will flow into the rainwater collecting culvert 2 through the water inlet pipe 51 to replenish water in the rainwater collecting culvert 2. Excessive rainwater in the rainwater collecting culvert 2 will be discharged into the municipal pipeline 6 through the drainage pipe 61.

[0033] People can use the sediment pump 24 to pump out the sediment deposited in the rain collecting culvert 2 to clean the rain collecting culvert 2. The sediment pump 24 can also pump out the rainwater collected in the rain collecting culvert 2 to use it as irrigation water for surrounding green plants, thereby collecting and utilizing rainwater. During irrigation, people can also judge the water level and the remaining amount of rainwater in the rain collecting culvert 2 by observing the height of the indicator sign 42, which is convenient for operation.
