Description

Technical Field

[0001] This utility model relates to the field of green ecological roads, and in particular to a garden green ecological road structure. Background Technology

[0002] Traditional urban roads generally use impermeable materials, which causes rainwater runoff to accumulate rapidly, easily causing considerable trouble for people traveling, especially in parks and other places where people stroll and play. If rainwater cannot be effectively drained from these roads, the experience of nearby residents will be very poor. Moreover, currently, the green belts on both sides of park roads are mostly in the form of isolation belts, which are separated from the road structure and make it difficult to form a coordinated rainwater management and ecological purification system.

[0003] In existing technologies, permeable pavement can alleviate drainage problems, but its filtration capacity is limited and it lacks organic integration with greening modules, making it difficult to maximize ecological benefits. Therefore, there is an urgent need for a composite road structure that integrates rainwater diversion, filtration, infiltration and ecological greening to improve the sustainability and ecological function of urban roads. Utility Model Content

[0004] The purpose of this utility model is to provide a landscape greening ecological road structure to solve the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] An ecological road structure for landscaping includes a main road and greening modules. The greening modules are arranged on both sides of the main road. The main road includes several interconnected permeable bricks. A brick-laying connecting layer is laid at the lower end of the permeable bricks. A mixed sand and gravel layer is laid at the lower end of the brick-laying connecting layer. A guide plate is fixedly installed at the bottom of the mixed sand and gravel layer. A drainage ditch is provided at the bottom of the greening module. The two ends of the guide plate are respectively connected to the corresponding drainage ditch, allowing rainwater to pass through from top to bottom and flow into the drainage ditch along the guide plate.

[0007] Preferably, the greening module includes planting soil, with a base at the bottom of the planting soil, the upper surface of the base being inclined, and plants planted on top of the planting soil. A mesh layer is installed between the planting soil and the mixed sand and gravel layer.

[0008] Preferably, the permeable brick is provided with a drainage cavity, the bottom of the drainage cavity has a through hole, and support columns are distributed and installed on the upper end surface of the drainage cavity, and a support platform is fixedly connected to the upper end surface of the support columns.

[0009] Preferably, a concave stepped platform is provided at the outer edge of the support platform and at the inner edge of the top of the permeable brick, and a filter screen is fixedly installed on the concave stepped platform.

[0010] Preferably, the permeable brick has a concave cavity at its bottom.

[0011] Preferably, the surface of the guide plate is provided with a plurality of concave guide grooves.

[0012] The advantages and positive effects of this utility model are:

[0013] This utility model combines an ecological road structure with greening modules to achieve multiple functions such as efficient rainwater diversion, filtration and purification, ecological restoration, and landscape beautification. The inclined design of the diversion plate, combined with the concave diversion channel, quickly guides rainwater to flow to the drainage ditches on both sides. The mixed sand and gravel layer has both physical filtration and support functions, improving rainwater infiltration efficiency and reducing pollutants. The planting soil of the greening module and the barrier layer work together to promote rainwater infiltration to the base and flow into the drainage system, while providing a growth environment for plants and enhancing biodiversity. The drainage cavity and filter part of the permeable brick can intercept garbage and impurities, avoid blockage, and extend the service life of the road. The greening module serves as a road decoration, increasing the urban green coverage rate and mitigating the heat island effect. At the same time, the use of ecological materials and modular design enables low-cost maintenance and resource recycling. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:

[0025] Please see Figure 1-5This utility model provides an embodiment of a garden greening ecological road structure, including a main road and greening modules. Greening modules are installed on both sides of the main road for decoration. The main road is based on a foundation 10 at its bottom. A guide plate 11 is laid on the upper part of the foundation 10, and the guide plate 11 slopes from the middle to both sides to facilitate rainwater drainage. A mixed sand and gravel layer 12 is laid on the upper side of each sloped section of the guide plate 11, through which rainwater is partially and physically drained. The system filters water through a paving brick connecting layer 14 laid on top of the mixed sand and gravel layer 12. Several permeable bricks 15 are fixedly installed on the paving brick connecting layer 14. Adjacent permeable bricks 15 are spliced ​​together to form the surface layer of the road. Rainwater can pass through the permeable bricks 15 and enter the mixed sand and gravel layer 12. A drainage ditch 20 is provided at the bottom of the green plant module. The two ends of the guide plate 11 are respectively connected to the corresponding drainage ditch 20, allowing rainwater to pass through from top to bottom and flow along the guide plate 11 into the drainage ditch 20.

[0026] It is worth mentioning that, in this embodiment, the greening module includes planting soil 22, with a base 21 at the bottom of the planting soil 22. The upper surface of the base 21 is inclined, and a plant 23 is planted on top of the planting soil 22. A barrier layer 13 is installed between the planting soil 22 and the mixed sand and gravel layer 12. When the rainfall is heavy, the rainwater will penetrate through the planting soil 22 to the upper surface of the base 21, and then flow along the upper surface of the base 21 through the barrier layer 13 and merge with the water guided by the surface of the guide plate 11 into the drainage ditch 20.

[0027] It should be noted that, in this embodiment, the permeable brick 15 is provided with a drainage cavity 16, the bottom of the drainage cavity 16 has a through hole, and support columns 19 are distributed and installed on the upper end face of the drainage cavity 16. A support platform 17 is fixedly connected to the upper end face of the support column 19. Concave stepped platforms are respectively provided at the outer edge of the support platform 17 and the inner edge of the top of the permeable brick 15. A filter screen 18 is fixedly installed on the concave stepped platform. Rainwater enters the drainage cavity 16 through the surrounding filter screen 18 and flows to the bottom for discharge. At the same time, the filter screen 18 can also intercept most of the garbage and impurities. The middle is supported by the support platform 17, so people can stand on it well. The bottom of the permeable brick 15 is provided with a concave cavity, so that rainwater can pass through the entire permeable brick 15 and enter the mixed sand and gravel layer 12.

[0028] In another embodiment, the surface of the guide plate 11 is provided with a plurality of concave guide grooves, thereby greatly improving the guidance of rainwater.

[0029] The mixed sand and gravel layer 12 is made by mixing garnet with diatomaceous earth, which can not only filter rainwater to a certain extent, but also provide support for the road.

[0030] In practice, an ecological road will be designed within the urban ecological park, connecting the visitor center with the natural wetland. The road will be 500 meters long and 8 meters wide, with green modules (3 meters wide on each side) on both sides. The main road surface will be paved with permeable bricks and equipped with a rainwater filtration system. This road will primarily be used for pedestrian and bicycle traffic, while also serving rainwater management, ecological restoration, and landscaping functions.

[0031] Among them, 23 plant species were selected:

[0032] Tree layer:

[0033] Camphor trees: They are pollution-resistant and have dense canopies that can provide shade and cool the air.

[0034] Ginkgo: Colorful autumn foliage, with strong air-purifying capabilities.

[0035] Shrub layer:

[0036] Red Photinia: Evergreen all year round, brightly colored, and highly resistant to adverse conditions.

[0037] Purple-leaved barberry: drought-resistant, creating a striking color contrast.

[0038] Ground cover plants:

[0039] Clover

[0040] Iris (Iris taurensis): Tolerates poor soil, blooms in summer, and attracts pollinating insects.

[0041] February Orychophragmus violaceus: Blooms in spring, covering bare ground in early spring.

[0042] Foundation treatment: The original soil under the road is compacted and an impermeable membrane is laid (to prevent groundwater seepage and pollution).

[0043] Deflector plate installation: High-strength concrete deflector plates (10cm thick) are used, with deflection grooves carved on the surface and an inclination angle of 1.5% to ensure that rainwater is quickly diverted to the green plant modules on both sides.

[0044] Mixed sand and gravel layer laying:

[0045] Material ratio: Diatomaceous earth (60%) + garnet (30%) + crushed stone (10%). After mixing evenly, lay a 30cm thick layer. Diatomaceous earth adsorbs suspended particles, garnet provides mechanical support, and crushed stone enhances permeability.

[0046] Permeable brick laying: The gaps between adjacent permeable bricks are filled with permeable resin adhesive to prevent displacement.

[0050] Plant arrangement:

[0051] Trees are planted at a spacing of 4 meters, with a canopy coverage of 80%.

[0052] Shrubs are planted in clusters of 3 plants per square meter to create a layered hedge.

[0053] Ground cover plants and flowers are mixed and sown together, with a coverage rate of ≥90%.

[0054] Drainage channel design: A drainage channel is set at the bottom of the green plant module, which connects to the park's artificial wetland.

[0055] Ecological wetlands: Rainwater is purified using plants such as irises and reeds, and excess water is used to replenish the park's landscape water bodies.

[0056] Permeability: The permeable bricks have a permeability rate of up to 15 L / m²·min, and the mixed sand and gravel layer has a filtration efficiency of up to 90%, reducing the annual runoff of the road by 60%.

[0057] Flood control capability: During heavy rain, rainwater is quickly discharged through the diversion plate-mixed sand and gravel layer-drainage channel system, reducing the risk of waterlogging.

[0058] Carbon sequestration capacity: The annual carbon sequestration of the tree layer reaches 2.5 kg / m², and the overall carbon sequestration of the green plant module increases by 30% (refer to the case of Yuhua South Road in Nanjing).

[0059] Biodiversity: The green plant module attracts pollinating insects such as bees and butterflies, as well as small birds, forming a miniature ecosystem.

[0060] Microclimate regulation: In summer, the surface temperature of roads is 5-8℃ lower than that of traditional asphalt pavements, mitigating the heat island effect.

[0061] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
