Technical Field
[0001] The utility model relates to the technical field of sponge city design, in particular to a road used in a sponge city. Background Art
[0002] At present, the construction of sponge cities is constantly deepening, and the concept of sidewalks with sponge city functions has been deeply rooted in people's minds. Generally speaking, sponge cities mainly achieve low-impact or low-impact development through steps such as "infiltration, stagnation, storage, purification, use, and discharge" to achieve the construction effect of sponge cities. Urban roads, as the main carrier of sponge city construction, also need to be combined with engineering measures to carry out sponge construction according to the timing conditions such as road grade and regional environment.
[0003] At present, the construction of sponge-like sidewalks in urban roads is widely used. However, the existing road design has problems such as infiltration blockage and unreasonable collection, which easily lead to the accumulation of mud and sand on the road surface. Utility Model Content
[0004] Based on the above description, the utility model provides a road for a sponge city to solve the deficiencies in the prior art.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] A road for a sponge city, comprising:
[0007] Non-motorized vehicle lanes shall be provided with rainwater inlets connected to sewer pipes on their road surfaces;
[0008] The vehicle lane is set on one side of the non-motorized vehicle lane, and a rainwater inlet connected to the sewer pipe is set at its edge;
[0009] The sidewalk is set on the other side of the non-motorized vehicle lane. It is a permeable paved road surface connected to a sewer pipe underneath.
[0010] On the basis of the above technical solution, the present invention can also be improved as follows.
[0011] Furthermore, prefabricated curbstones and prefabricated paving stones are provided at the edge of the permeable paved surface. The prefabricated curbstones are vertically arranged as the edge of the sidewalk. The prefabricated paving stones are laid flat on the sidewalk surface and abut against the prefabricated curbstones. The prefabricated curbstones are provided with transverse through grooves, in which filter mesh sheets are provided. The prefabricated paving stones are provided with receiving grooves, in which filter mesh sedimentation grooves are embedded.
[0012] Furthermore, the receiving groove is arranged close to the edge of the prefabricated paving stone.
[0013] Furthermore, the prefabricated kerbstone is integrally connected with the prefabricated curbstone to form an L-shaped curbstone.
[0014] Furthermore, a green belt is provided between the carriageway and the non-motorized vehicle lane.
[0015] Furthermore, a first overflow type rainwater outlet is arranged in the edge green belt, and the bottom of the first overflow type rainwater outlet is connected to the sewer pipe through a pipeline.
[0016] Furthermore, a pedestrian green belt is provided between the non-motorized vehicle lane and the sidewalk.
[0017] Furthermore, a second overflow type rainwater outlet is arranged in the pedestrian green belt, and the bottom of the second overflow type rainwater outlet is connected to the sewer pipe through a pipeline.
[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0019] Prefabricated curbstones (including filter mesh), prefabricated paving stones (including sedimentation tanks) or combined prefabricated L-shaped curbstones with filter sedimentation tanks are used on the side of the separated green belts to meet the functional needs of rainwater collection on the road surface, while also filtering and blocking lighter floating garbage such as leaves, plastic bags and other garbage in the rainwater, and settling heavier debris such as mud and sand, ensuring the effect of rainwater infiltration and collection. Under the permeable pavement of the sidewalk, engineering measures such as setting soft steel wire permeable pipes in the gravel layer under the sidewalk structure and setting finished permeable water collection inspection wells on the permeable sidewalk structure can ensure the seepage and water collection effect under the sidewalk sponge city pavement.

DETAILED DESCRIPTION
[0029] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0031] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.
[0032] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.
[0033] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.
[0034] like Figure 1-7 A road for a sponge city shown in the figure comprises a non-motorized vehicle lane 2, a carriageway 1 and a sidewalk 3. The carriageway 1 and the sidewalk 3 are located on both sides of the non-motorized vehicle lane 2, respectively. The road surface of the carriageway 1 forms a slope that descends toward the non-motorized vehicle lane 2, and a rainwater inlet connected to a sewer pipe 12 is provided on the edge of the road surface of the carriageway 1 near the non-motorized vehicle lane 2. The road surface of the sidewalk 3 is a permeable paved road surface, and the accumulated water can penetrate into the receiving and collecting structure below, and the bottom of the receiving and collecting structure is connected to the sewer pipe 12.
[0035] Specifically, a side green belt 4 is arranged between the carriageway 1 and the non-motorized vehicle lane 2, and the side green belt 4 separates the carriageway 1 from the non-motorized vehicle lane 2. In order to prevent the accumulated water in the side green belt 4 from spreading into the non-motorized vehicle lane 2, a first overflow type rainwater outlet 10 is arranged in the side green belt 4, and the bottom of the first overflow type rainwater outlet 10 is connected to the sewer pipe 12 through a pipeline.
[0036] Specifically, a pedestrian green belt 5 is set between the non-motorized vehicle lane 2 and the sidewalk 3, and the pedestrian green belt 5 separates the sidewalk 3 from the non-motorized vehicle lane 2. In order to prevent the accumulated water in the pedestrian green belt 5 from spreading to the non-motorized vehicle lane 2 and the sidewalk 3, a second overflow type rainwater outlet 11 is set in the side green belt 4, and the bottom of the second overflow type rainwater outlet 11 is connected to the sewer pipe 12 through a pipeline.
[0037] A rainwater pipe inspection well 13 is designed at a low-lying part of the road surface on the non-motorized vehicle lane 2 , and the rainwater pipe inspection well 13 is connected to the sewer pipe 12 .
[0038] In order to prevent the sediment in the green belt from entering the sidewalk 3, in this solution, prefabricated curbstones 6 and prefabricated paving stones 7 are arranged at the edge of the permeable paving surface. The prefabricated curbstones 6 are arranged vertically as the edge of the sidewalk 3. The prefabricated paving stones 7 are laid flat on the sidewalk 3 and abut against the prefabricated curbstones 6. The prefabricated curbstones 6 are provided with transverse through grooves, in which filter mesh pieces 8 are arranged. The prefabricated paving stones 7 are provided with receiving grooves, in which filter mesh sedimentation grooves 9 are embedded. When the accumulated water in the pedestrian green belt 5 reaches the height of the through groove, the accumulated water is filtered through the filter mesh pieces 8 of the prefabricated curbstones 6, leaving the sediment in the green belt. When the rainfall is too heavy, the splashing rainwater will carry mud and sand over the prefabricated curbstone 6 and enter the sidewalk 3. Therefore, a prefabricated kerb 7 with a filter sedimentation tank 9 is designed at the edge of the prefabricated curbstone 6 to filter and collect the mud and sand. The filter sedimentation tank 9 is detachably connected to the prefabricated kerb 7, and can be manually lifted up to pour out the internal mud and sand afterwards.
[0039] Preferably, the receiving tank is arranged close to the edge of the prefabricated paving stone 7. Accordingly, the slope of the prefabricated paving stone 7 decreasing in height toward the prefabricated curbstone 6 can be designed so that the position of the filter sedimentation tank 9 is at the lowest. The structure and shape of the receiving tank can be designed in different types according to the needs, for example Figure 6 The middle of the edge shown, Figure 4 The top of the edge shown in the figure just keeps the filter screen sedimentation tank 9 at the lowest point.
[0040] Preferably, the prefabricated kerb 7 is integrally connected with the prefabricated curb 6 to form an L-shaped curb.
[0041] Since the sidewalk 3 is a paved road, it is convenient to install prefabricated paving stones 7, but it is inconvenient to install non-motorized vehicle lanes 2 and carriageways 1. Prefabricated curbstones 6 can be set on both sides of the pedestrian green belt 5 and the side green belt 4 to play a certain role in blocking sediment.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
