Abstract
Description
Technical Field
[0001] This disclosure relates to the field of urban design technology, and more specifically, to a road green belt structure. Background Technology
[0002] In recent years, the concept of "sponge city" has been proposed, aiming to achieve the goals of infiltration, retention, storage, purification, utilization, and drainage through various engineering measures in urban construction. Roadside green belts serve as the carrier for realizing sponge cities. In conventional designs, roadside green belt structures mostly consider reserving certain blocks for direct planting of green crops.
[0003] However, when there is heavy rainfall in the green belt, poor drainage causes rainwater to accumulate in the green belt, posing a certain threat to the flowers, trees and shrubs in the green belt, causing them to drown.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0005] The purpose of this disclosure is to provide a road green belt structure that improves drainage.
[0006] According to one aspect of this disclosure, a road green belt structure is provided, the road green belt structure comprising:
[0007] The main body of the green belt is located between the road and the sidewalk along its width. Along its length, the main body includes a first planting area, multiple infiltration areas, and a second planting area. The first planting area extends along the length, and the second planting area and the infiltration areas are alternately distributed along the length and located on either side of the first planting area along the width. In the height direction of the main body, the height of the first planting area is greater than the height of the second planting area. The infiltration areas are equipped with overflow outlets.
[0008] Multiple first curb stones are located between the main body of the green belt and the sidewalk, and the height of the first curb stones in the height direction is not greater than the height of the sidewalk.
[0009] Multiple second curb stones are located between the main body of the green belt and the road, and the height of the second curb stones is greater than the height of the road in the vertical direction; the second curb stones are arranged adjacent to the infiltration zone, and rainwater inlets are provided on the second curb stones adjacent to the infiltration zone;
[0010] Multiple rainwater drainage pipes are provided, and each of the multiple rainwater drainage pipes is configured to correspond one-to-one with the multiple infiltration zones; the inlet of each rainwater drainage pipe is located in the first planting area near the first curbstone, and the outlet is located in the infiltration zone.
[0011] In one exemplary embodiment of this disclosure, the height of the infiltration zone is less than the height of the first planting area, the second planting area, and the road.
[0012] In one exemplary embodiment of this disclosure, the height of the first planting area decreases in the direction from the side of the first curbstone closer to the second curbstone.
[0013] In one exemplary embodiment of this disclosure, the height of the second planting area decreases towards both sides along the length direction, and / or the height of the second planting area decreases in the direction of the first curbstone and the second curbstone near both sides.
[0014] In one exemplary embodiment of this disclosure, the road green belt structure further includes:
[0015] A filtration device is provided at the inlet of the rainwater drainage pipe.
[0016] In one exemplary embodiment of this disclosure, the first planting area extends in an S-shape along the length direction.
[0017] In one exemplary embodiment of this disclosure, the first planting area is a shrub planting area, and / or the second planting area is a tree planting area.
[0018] In one exemplary embodiment of this disclosure, the maximum height difference between the first planting area and the second planting area is 40cm to 60cm, and / or the maximum height difference between the second planting area and the infiltration area is 50cm to 70cm.
[0019] In one exemplary embodiment of this disclosure, in the length direction, the length of the second planting area is 4.5m to 6m, and the length of the infiltration area is 6m to 12m.
[0020] In one exemplary embodiment of this disclosure, the length of the rainwater inlet is 1m to 2m, and the distance between two adjacent rainwater inlets is 9m to 12m.
[0021] The road green belt structure disclosed herein includes a first curbstone located between the main body of the green belt and the sidewalk, with its height not exceeding that of the sidewalk. This allows rainwater from the sidewalk to drain into the main body of the green belt, irrigating the plants within. A second curbstone is located between the main body of the green belt and the road, with its height exceeding that of the road. The second curbstone is adjacent to an infiltration zone and has a drain inlet, allowing rainwater from the road to drain into the infiltration zone promptly. Simultaneously, multiple rainwater drainage pipes are correspondingly installed for each infiltration zone. The inlets of the rainwater drainage pipes are located in the first planting area near the first curbstone, and the outlets are located in the infiltration zones. This allows excess rainwater drained from the sidewalk into the green belt to be diverted to the infiltration zones via the drainage pipes, and then discharged into the municipal stormwater pipes through overflow outlets in the infiltration zones. This prevents excessive rainwater in the main body of the green belt from causing waterlogging and root rot in the plants.

[0036] In recent years, sponge city roads have been incorporated into urban road systems based on the concept and measures of sponge cities. Sponge road systems, in conjunction with sponge city construction, achieve the low-impact development control targets and indicators proposed in relevant plans. In sponge cities, road runoff rainwater is systematically collected and transported, pre-treated through interception and other processes, and then introduced into green belts. After treatment by low-impact development facilities located within these green belts, primarily for retention, storage, and regulation, the rainwater is discharged into rivers and lakes via municipal stormwater pipes.
[0037] In road systems, bioretention ponds and other sponge city measures are installed in roadside green belts. By controlling runoff channels, these green belts retain, filter, and infiltrate rainwater from the roadway, before excess rainwater is discharged into surrounding green areas or storm drains. Simultaneously, due to the limitations of cross slopes, the central green belts of roads typically lack drainage and infiltration capabilities, thus the side medians bear a greater responsibility for rainwater collection. However, old urban areas generally suffer from excessively narrow green belts, resulting in extremely limited areas for rainwater retention and infiltration after planting trees.
[0038] A common approach to creating "sponge-like" roads involves incorporating the central green belt into a sponge city strategy. This integrates the retention ponds on both sides of the road and the central green belt, which were previously unconnected, into a new drainage and green ecosystem, taking into account the existing road cross slope. However, while the median strip often meets the requirements for rainwater collection, it cannot guarantee the growth needs of trees, thus affecting the shading of sidewalks.
[0039] To address the aforementioned technical problems, this disclosure provides a road green belt structure, such as... Figures 1-3 As shown, the road green belt structure includes: a green belt body 100, multiple first curb stones 121, multiple second curb stones 122, and multiple rainwater drainage pipes 130. The green belt body 100 is located between the road 300 and the sidewalk 200 along the width direction Y. The green belt body 100 includes a first planting area 111, multiple infiltration areas 113, and a second planting area 112 along the length direction X. The first planting area 111 extends along the length direction X, and the second planting area 112 and the infiltration area 113 are alternately distributed along the length direction X and are located on both sides of the first planting area 111 in the width direction Y. In the height direction Z of the green belt body 100, the height of the first planting area 111 is greater than the height of the second planting area 112. The infiltration area 113 is provided with an overflow outlet. 140; Multiple first curb stones 121 are located between the main body of the green belt 100 and the sidewalk 200, and the height of the first curb stones 121 in the height direction Z is not greater than the height of the sidewalk 200; Multiple second curb stones 122 are located between the main body of the green belt 100 and the road 300, and the height of the second curb stones 122 in the height direction Z is greater than the height of the road 300; The second curb stones 122 are set adjacent to the infiltration area 113, and the second curb stones 122 adjacent to the infiltration area 113 are provided with rainwater inlets 123; Multiple rainwater drainage pipes 130 are set one-to-one with multiple infiltration areas 113; The inlet 131 of the rainwater drainage pipe 130 is located in the first planting area 111 near the first curb stone 121, and the outlet 132 is located in the infiltration area 113.
[0040] The road green belt structure disclosed herein includes a first curbstone 121 located between the main body of the green belt 100 and the sidewalk 200, with the height of the first curbstone 121 in the Z-direction not exceeding the height of the sidewalk 200. This allows rainwater from the sidewalk 200 to drain into the main body of the green belt 100 through the first curbstone 121, irrigating the plants planted in the main body of the green belt 100. A second curbstone 122 is located between the main body of the green belt 100 and the road 300, with the height of the second curbstone 122 in the Z-direction exceeding the height of the road 300. The second curbstone 122 is adjacent to the infiltration zone 113. The stone 122 is equipped with a rainwater inlet 123, which allows rainwater from the road 300 to be discharged into the infiltration area 113 in a timely manner. At the same time, multiple rainwater drainage pipes 130 are set up one-to-one with multiple infiltration areas 113. The inlet 131 of the rainwater drainage pipe 130 is located in the first planting area 111 near the first curb stone 121, and the outlet 132 is located in the infiltration area 113. Excess rainwater discharged from the sidewalk 200 into the green belt can be diverted to the infiltration area 113 through the rainwater drainage pipe 130, and then discharged into the municipal rainwater pipe through the overflow outlet 140 in the infiltration area 113. This avoids the problem of waterlogging and root rot in the plants caused by excessive rainwater in the main body of the green belt 100.
[0041] Specifically, the first planting area 111 is a shrub planting area, and / or the second planting area 112 is a tree planting area. The height of the first planting area 111 is greater than the height of the second planting area 112. The first planting area 111 can be a shrub planting area, and the second planting area 112 can be a tree planting area. This ensures that the water-tolerant plants in the main body of the green belt 100 can be fully irrigated, while avoiding the problem of waterlogging and root rot in water-intolerant plants.
[0042] The infiltration zone 113 can be a layer of sand and gravel, which is conducive to drainage; of course, water-tolerant plants and lawns can also be planted in the infiltration zone 113.
[0043] The overflow outlet 140 on the infiltration zone 113 can be located at the lowest point of the infiltration zone 113 so that rainwater can be discharged through the overflow outlet 140.
[0044] The overflow outlet 140 on the infiltration zone 113 can be equipped with a filter to filter out impurities in the rainwater and prevent them from clogging the rainwater pipe connected to the overflow outlet 140. The filter can be a filter plate, filter screen, or filter cover, etc.
[0045] Specifically, such as Figures 1-3As shown, the first planting area 111 extends in an S-shape along the length direction X, meaning the planted shrubs can extend in an S-shape along the extension direction of the road 300 to enhance the aesthetics of the green belt. Through the S-shaped shrub planting area, tree planting areas and infiltration areas 113 can be set up on both sides of the shrub planting area, allowing the tree planting areas and infiltration areas 113 to alternate along the length direction X. The tree planting areas are all located on the side closer to the first curb 121, and the infiltration areas 113 are all located on the side closer to the second curb 122. That is, the tree planting areas are far from the infiltration areas 113 and also far from the road 300, closer to the sidewalk 200. The sidewalk 200 receives relatively less rainwater, thus further preventing waterlogging and root rot problems in water-intolerant trees and shrubs. The infiltration zone 113 is located close to the road 300, which can promptly and directly discharge rainwater flowing from the road 300 into the main body of the green belt 100 through the overflow outlet 140, avoiding soaking of the tree planting area, and thus further preventing water-intolerant trees and other plants from being soaked and rotting.
[0046] The maximum height difference between the first planting area 111 and the second planting area 112 is 40cm to 60cm, for example, 40cm, 45cm, 50cm, 55cm, 60cm, etc., which will not be listed here. The height range of the first planting area 111 can be -200mm to 300mm, for example, -200mm, -100mm, 0, 100mm, 200mm, etc.; the height range of the second planting area 112 can be 300mm to 400mm.
[0047] The maximum height difference between the second planting area 112 and the infiltration area 113 is 50cm to 70cm, for example, 50cm, 55cm, 60cm, 65cm, 70cm, etc., which will not be listed here. The height range of the first planting area 111 can be -200mm to -100mm.
[0048] The length of each second planting area 112 is 4.5m to 6m, such as 4.5m, 5m, 5.5m, 6m, etc., which will not be listed here.
[0049] The length of the infiltration zone 113 is 6m to 12m, such as 6m, 7m, 8m, 9m, 10m, 11m, 12m, etc., which will not be listed here in this disclosure.
[0050] The length of the rainwater inlet 123 is 1m to 2m, such as 1m, 1.2m, 1.5m, 1.8m, 2m, etc., which will not be listed here.
[0051] The distance between two adjacent rainwater inlets 123 is 9m to 12m, such as 9m, 10m, 11m, 12m, etc., which will not be listed here.
[0052] In one embodiment, the height of the infiltration zone 113 is less than the height of the first planting area 111, the second planting area 112, and the road 300, i.e., the infiltration zone 113 is set at a lower elevation. By setting the infiltration zone 113 at a lower elevation, it is beneficial to drain water quickly through the infiltration zone 113, avoiding waterlogging and root rot in the plants in the second planting area 112. At the same time, it is beneficial to facilitate the timely drainage of rainwater from the sidewalk 200 into the main body of the green belt 100 through the rainwater drainage pipe 130 into the infiltration zone 113, further preventing waterlogging and root rot in the plants in the second planting area 112.
[0053] When the height of the road at 300 is used as the reference height of the horizontal plane, the height of the infiltration zone 113 can be -300mm to -100mm, such as -300mm, -250mm, -200mm, -150mm, -100mm, etc., which will not be listed here. Of course, the height of the infiltration zone 113 can be less than -300mm or greater than -100mm, and this disclosure does not impose any restrictions on it.
[0054] It is understood that the dimensions of the above-described structures are merely preferred examples, and those skilled in the art may select dimensions outside the above numerical range. This disclosure does not impose any restrictions on this, and all changes in dimensions fall within the protection scope of this disclosure.
[0055] Among them, such as Figure 2 and Figure 3 As shown, the first planting area 111 decreases in height in the direction from the first curb 121 towards the second curb 122. By making the first planting area 111 decrease in height in the direction from the first curb 121 towards the second curb 122, it is beneficial for rainwater flowing in from the sidewalk 200 to flow down into the infiltration area 113, thus avoiding soaking of the planting area.
[0056] Among them, such as Figure 2 and Figure 3 As shown, the height of the second planting area 112 decreases towards both sides along the length direction X. By making the height of the second planting area 112 decrease towards both sides along the length direction X, rainwater on the second planting area 112 can flow to the first planting areas 111 on both sides, avoiding excessive rainwater accumulation on the second planting area 112, thereby further preventing waterlogging and root rot problems for water-intolerant trees and other plants planted in the second planting area 112.
[0057] Among them, such as Figure 2 and Figure 3As shown, the second planting area 112 decreases in height near the second curbstone 122. By making the second planting area 112 decrease in height near the second curbstone 122, rainwater on the second planting area 112 can flow to the side of the road 300, that is, flow into the infiltration area 113, avoiding excessive accumulation of rainwater on the second planting area 112, thereby further preventing waterlogging and root rot problems for water-intolerant trees and other plants planted on the second planting area 112.
[0058] It is understood that the aforementioned height reduction can be a continuous height reduction structure or a stepped height reduction structure, and this disclosure does not impose any restrictions on it.
[0059] Specifically, the road green belt structure also includes a filter device, which is installed on the inlet 131 of the rainwater drainage pipe 130 to filter the rainwater flowing into the inlet 131 of the rainwater drainage pipe 130 and prevent debris from entering the rainwater drainage pipe 130 and causing the rainwater drainage pipe 130 to become blocked.
[0060] The filtration device can be a filter plate, filter screen, or filter cover, etc.
[0061] The outlet 132 of the rainwater drainage pipe 130 can be located in the infiltration zone 113, guiding rainwater to the infiltration zone 113 and then flowing into the overflow port 140 in the infiltration zone 113; or, the outlet 132 of the rainwater drainage pipe 130 can be directly connected to the overflow port 140, that is, the rainwater passing through the rainwater drainage pipe 130 can be directly discharged into the rainwater pipe through the overflow port 140.
[0062] In summary, the technical solution adopted in this disclosure involves the rational planning of the topography of the planting area, soil mounding, planting layout, and plant varieties, as follows:
[0063] 1. Apart from water-tolerant and flood-resistant trees such as bald cypress, maple, and elm, most of the trees used for roadside trees in my country are not water-tolerant. To avoid the death of tree roots and stems or growth problems caused by water accumulation, the planting area of trees in green belts should be relatively raised, and the drainage of the soil in this area should be ensured.
[0064] 2. Within a 1-3 meter wide green belt, planting areas for trees, shrubs, and water-tolerant plants can be planned and arranged at intervals. In sunken tree belts, sufficient drainage space should be ensured on both sides of the tree roots to guarantee unobstructed flow; if insufficient space is available, overflow outlets should be provided in each enclosed area. The layout should be designed in accordance with the streamlined shape of the plan and the undulating terrain to satisfy both functionality and aesthetics.
[0065] 3. Designed to integrate with road storm drains for efficient collection of road rainwater.
[0066] 4. Plant water-tolerant plants, lawns, or pave gravel in the rainwater infiltration area of the green belt, and set the overflow outlet in an area that is easy to inspect.
[0067] Compared to existing technologies, this technology ensures the growth of plants in green belts and enriches the plant landscape of roadside green belts, especially the growth of street trees in 1-3 meter wide green belts, which has a very positive effect on the growth of roadside shade trees. The design fully utilizes the combination of roads and green spaces to effectively control rainwater runoff. By absorbing, storing, infiltrating, and slowly releasing rainwater, it reduces runoff peaks, helps reduce urban flooding, and prevents trees from rotting due to waterlogging after the green belts subside. This technology is highly suitable for the renovation and upgrading of old neighborhoods, as well as neighborhoods with narrow road cross-sections that are difficult to implement sponge city systems.
[0068] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
