Description

Technical Field

[0001] This utility model relates to the field of embankment engineering technology, and in particular to a composite resilient embankment structure for green spaces. Background Technology

[0002] The composite resilient embankment surrounding the green space is designed by combining ecological materials with engineering structures. Through multi-level gentle slopes and soil stabilization by vegetation roots, it forms a flexible boundary that can buffer the impact of water flow and adapt to changes in water level. The embankment integrates landscape walkways and ecological habitats, which not only enhances the area's flood control capacity but also provides living space for animals and plants, achieving an organic unity of safety, ecology, and recreation.

[0003] In existing technologies, traditional urban river or lake embankments are mostly made of hard structures such as reinforced concrete and masonry blocks. This not only blocks the exchange of matter and energy between aquatic and terrestrial ecosystems, leading to the loss of riparian habitats and a decline in biodiversity, but also fails to provide an environment for aquatic plants and microorganisms to attach and grow, resulting in weak water self-purification capacity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as rigid structures that block the exchange of matter and energy between aquatic and terrestrial ecosystems, fail to provide an environment for aquatic plants and microorganisms to attach and grow, and have weak water self-purification capabilities. Therefore, this invention proposes a composite resilient embankment structure for green spaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite resilient embankment structure around a green space, comprising: The main body of the embankment consists of a base layer, an underwater purification layer, an energy dissipation zone, a buffer zone, and a slope. The underwater purification layer and the energy dissipation zone are located between the river water and the base layer. The energy dissipation zone is located above the underwater purification layer. The base layer and the slope are located on the side of the underwater purification layer and the energy dissipation zone away from the river water. The buffer zone and the slope are both located above the base layer.

[0006] In one possible design, the underwater purification layer consists of gabion cages and a riprap bed, with the gabion cages located above the riprap bed. The gabion cages are filled with gravel and ecological ceramsite to adsorb pollutants, and submerged plants are planted on the surface of the gabion cages to absorb pollutants and inhibit algae growth.

[0007] In one possible design, the energy dissipation zone is dry-laid from multiple porous eco-concrete blocks, and the energy dissipation zone is stepped. The holes in the energy dissipation zone are filled with soil and planted with flood-tolerant wetland plants to reduce wave energy and provide habitat for riparian organisms.

[0008] In one possible design, the buffer zone consists of a walkway and a permeable concrete layer, the walkway being paved with permeable bricks and the permeable concrete layer being configured to allow water accumulated on the walkway to seep into the ground.

[0009] In one possible design, the slope consists of a ramp and an L-shaped wall, the L-shaped wall being L-shaped and the ramp being located above the L-shaped wall. The slope is covered with three-dimensional geocells, in which grass seeds are sprayed to fix the soil. The L-shaped wall is a reinforced concrete structure and provides stable support for the slope.

[0010] In one possible design, a drainage ditch is provided on the top of the base layer, and the drainage ditch is located between the walkway and the slope to collect water flowing down the slope surface and prevent water accumulation.

[0011] In this application, a riprap bed is laid underwater near the shore. The voids formed inside the riprap bed can provide refuge and survival space for aquatic organisms. A gabion cage is placed above the riprap bed, filled with crushed stone and ecological expanded clay pellets. Submerged plants can be planted on the surface of the riprap bed to further absorb pollutants and inhibit algae growth. Above the riprap bed is an energy dissipation zone constructed of porous ecological concrete blocks. The porous structure of the energy dissipation zone effectively reduces wave energy and minimizes water erosion on the bank slope. At the same time, the holes provide habitats for riparian insects, amphibians, and small fish. The energy dissipation zone is stepped, and flood-tolerant wetland plants can be planted in the holes. A buffer zone is laid on the base layer on one side of the underwater purification layer and the energy dissipation zone. The buffer zone consists of a walkway and a permeable concrete layer. The walkway is laid on the base layer through the permeable concrete layer, and water accumulated on the walkway can seep into the ground through the permeable concrete layer. A drainage ditch is provided between the buffer zone and the slope to collect water flowing down the slope surface. The slope is located above an L-shaped wall, which provides stable support for the slope.

[0012] Beneficial effects: In this utility model, the composite resilient embankment structure around the green space has an underwater riprap bed that provides refuge space for aquatic organisms. The gravel and ecological ceramsite in the gabion cages, combined with the submerged plants planted on the surface, can absorb pollutants and inhibit algae growth. The porous structure of the energy dissipation zone not only reduces wave energy and water erosion, but its holes also provide habitats for various organisms. The stepped design is conducive to planting flood-tolerant wetland plants and promotes biodiversity. In this utility model, the composite resilient embankment structure around the green space has a buffer zone where the walkway is laid on the base layer through a permeable concrete layer, which allows water to seep into the ground and effectively drain the water. The drainage ditch can collect water flowing down the slope surface to avoid water accumulation. The L-shaped wall is a reinforced concrete structure that provides stable support for the slope. The stepped structure of the energy dissipation zone and the base layer enhance the overall stability and adapt to different environments. This utility model has both ecological protection and engineering benefits. Ecologically, it creates habitat and reproduction space for a variety of organisms and improves the aquatic environment. In terms of engineering, it effectively drains and collects water flow, has a stable and reliable structure, and can adapt to the complex environment around green spaces, thus achieving a harmonious unity between ecology and engineering.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1 and Figure 3 A composite resilient embankment structure for green spaces is used in embankment engineering. The base layer 5 serves as the foundation of the entire embankment structure and must ensure its flatness and stability. A drainage ditch 12 is constructed on top of the base layer 5, located between the subsequent walkway 10 and the slope 6, to collect water flowing down the surface of the slope 6 and prevent water accumulation.

[0017] Reference Figure 1 and Figure 2An underwater purification layer 2 is constructed by laying a riprap bed 9 near the shore. The riprap bed 9 is made of appropriately sized stones, and the gaps between the stones provide refuge and living space for aquatic organisms. Gabion cages 8 are placed above the riprap bed 9. The gabion cages 8 are made of woven wire mesh and filled with gravel and ecological expanded clay pebbles. Submerged plants are planted on the surface of the gabion cages 8. These submerged plants can absorb pollutants in the water, inhibit algae growth, and improve the aquatic environment.

[0018] Reference Figure 1 The construction of Energy Dissipation Zone 3. Energy Dissipation Zone 3 is constructed by dry-laying multiple porous ecological concrete blocks, forming a stepped structure. The porous structure of the porous ecological concrete blocks effectively reduces wave energy and minimizes the erosion of the bank slope by the water flow. At the same time, these holes provide habitats for riparian insects, amphibians, and small fish. Soil is filled into the holes of Energy Dissipation Zone 3 and flood-tolerant wetland plants are planted. The stepped design promotes the growth of flood-tolerant wetland plants and enhances biodiversity.

[0019] Reference Figure 1 and Figure 3 Buffer zone 4 is located above base layer 5, on the side away from the river water, between underwater purification layer 2 and energy dissipation zone 3. Buffer zone 4 consists of walkway 10 and permeable concrete layer 11. The permeable concrete layer 11 is laid first, as it has good permeability, allowing water accumulated on walkway 10 to seep into the ground. Permeable bricks are then laid on the permeable concrete layer 11 to form walkway 10, ensuring both walking comfort and effective drainage.

[0020] In another embodiment: Reference Figure 1 and Figure 4 An improvement upon Example 1: Slope 13 is also located above base layer 5. Slope 13 consists of a sloping slope 6 and an L-shaped wall 7. The L-shaped wall 7 is a reinforced concrete structure, L-shaped, providing stable support for the sloping slope 6. Slope 6 is located above the L-shaped wall 7. Three-dimensional geocells are covered on the slope of slope 6, and grass seeds are sprayed into the cells. After the grass seeds grow, they can fix the soil, prevent soil erosion, and increase the ecological properties of the slope.
