Description

Technical Field

[0001] The utility model relates to the technical field of river bank protection, in particular to an urban river bank protection structure integrating landscape and ecological functions. Background Art

[0002] Ecological revetment technology, as an important innovation in the field of revetment protection, integrates the key principles of engineering mechanics, soil science, ecology and botany, and aims to enhance the structural stability of slopes or revetments. This technology forms a stable plant-rock and soil ecological relationship through the close integration of plant roots and engineering structures. The powerful anchoring function of plant roots provides a natural biological protection layer for the slope, which not only penetrates deep into the soil, enhances the shear strength and cohesion of the soil, and effectively resists soil erosion and landslide risks, but also improves the physical and chemical properties of the soil through the growth activities of the root system, thereby improving the overall stability of the revetment.

[0003] Current ecological revetment technologies rely on several specific structural forms in regulating river landscape and ecological functions: (1) Ecological concrete, a material made of specially graded concrete aggregates mixed with low-alkalinity cement, with a specific porosity, including plant growth bricks suitable for slope grass planting and retaining wall bricks for retaining wall construction. These materials must ensure appropriate porosity while maintaining structural durability to achieve high permeability and provide sufficient space for plant root growth. (2) Open-hole concrete blocks, with a filter structure on the soil side, and blocks connected by interlocking, hinged, cement mortar grooves, etc. The holes in the blocks below the normal water level are often filled with crushed stone or aquatic plants to prevent soil erosion; the holes above the normal water level are filled with planting soil to provide an ideal growth environment for vegetation. (3) Self-locking ecological revetment blocks, this solid concrete block has a locking structure, which can form an overall interlocking effect after installation to limit the movement between blocks. After the slope protection is formed, multiple ecological holes will be formed on the slope surface, and anti-filtration structures can be set up as needed to meet the needs of plant growth. Holes below the normal water level are also filled with gravel or aquatic plants to prevent soil erosion; holes above the normal water level are filled with planting soil and greening projects are carried out in conjunction.

[0004] However, although these technologies enhance structural stability through the plant-rock-soil system, the planted green plants remain unchanged during the river's flood, normal and dry seasons, lacking the ability to adapt. During the dry season, some submerged plants may be inhibited or even damaged by strong light and high water temperatures due to their growth to the water surface or the upper layer of the water body. On the contrary, during the flood season, the roots or the entire plant of the bank protection plant may suffer from lack of oxygen due to long-term immersion in water, resulting in inability to breathe normally, and eventually causing root rot. These problems not only affect the greening effect, but may also shorten the growth life of the plant.

[0005] At the same time, drainage measures are often overlooked in the process design of river bank protection. This results in rainwater directly washing away the slope during heavy rainfall seasons, causing soil erosion and water accumulation on local slopes, which has an adverse effect on the stability of bank protection and green plant growth. Utility Model Content

[0006] In order to enhance the diversity and adaptability of the plant-rock-soil system in conventional technologies, solve the challenges of plant life and landscape effects in different water levels (flood season, normal water season, and dry season) in rivers, and deal with the problems of local water accumulation and instability of bank slopes and green plant growth caused by rainwater scouring during heavy rainfall seasons, this utility model proposes an urban river bank protection structure that integrates landscape and ecological functions. This structure aims to achieve environmentally friendly and multifunctional river bank protection, ensuring the long-term stability and beauty of the river.

[0007] The urban river bank protection structure with integrated landscape and ecological functions provided in this application adopts the following technical solutions:

[0008] An urban river bank protection structure integrating landscape and ecological functions comprises a slope and a green plant module. A plurality of supporting structures are evenly arranged on both sides of the slope along the inclination direction of the slope. The top surfaces of the supporting structures are arranged horizontally. The two ends of the bottom wall of the green plant module are respectively mounted on the top walls of two supporting structures at the same height.

[0009] Furthermore, the top wall of the green plant module is flush with the top wall of the supporting structure located above.

[0010] Furthermore, a plurality of guide grooves are arranged on the slope along the horizontal direction, and the extension direction of the guide grooves is parallel to the inclination direction of the slope.

[0011] Furthermore, the bottom wall of the green plant module is partially fitted with the slope.

[0012] Furthermore, an inclined surface is provided in the green plant module, and the inclination direction of the inclined surface is parallel to the inclination direction of the slope.

[0013] Furthermore, a through groove is provided at the bottom of the green plant module.

[0014] Furthermore, a covering film is provided at the bottom of the green plant module, and water permeable holes are provided on the covering film.

[0015] Furthermore, a sand and gravel filter material layer and a rainwater storage module layer are provided in the green plant module, and the rainwater storage module layer is provided above the sand and gravel filter material layer.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. The top wall of the green plant module is designed to be flush with the supporting structure above, which ensures the visual unity and aesthetics of the revetment structure. During the flood season, if the roots or the entire plant of the lowest layer of green plant modules are immersed in water for a long time due to rising water levels, causing hypoxia and respiratory obstruction, the staff can easily pull out the green plant module and re-place it on the top layer. This flexible module position adjustment mechanism not only improves the survival rate of green plants, but also helps maintain the landscape effect of the revetment;

[0018] 2. The diversion trough can effectively guide the water flow and prevent the water flow from directly scouring the slope. In the green plant module, excess water will enter the trough through the water permeable holes, and then be discharged into the river through the diversion trough to ensure the orderly discharge of rainwater. In addition, the sand and gravel filter layer and rainwater storage module layer in the green plant module can significantly slow down the instantaneous impact of the water flow during heavy rainfall, thereby reducing the impact pressure of the water flow on the slope. At the same time, the two-layer structure can also effectively intercept pollutants in rainwater, which helps to reduce point source pollution and improve the quality of the water environment;

[0019] 3. The bottom wall of the green plant module fits closely with the slope, which significantly enhances the stability of the module, thereby effectively reducing the risk of module displacement caused by natural factors such as wind and rain erosion. At the same time, the inclined surface inside the green plant module not only ensures the stability of the plant during its growth, but also facilitates the natural discharge of rainwater, further ensuring good ventilation and air permeability of the plant roots, providing a more favorable environment for its healthy growth.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The embodiment of the present application discloses an urban river bank protection structure integrating landscape and ecological functions.

[0027] Reference Figure 1 and Figure 2 An urban river bank protection structure integrating landscape and ecological functions comprises a slope 1 and a plurality of green plant modules 2. A plurality of supporting structures 3 are evenly arranged on both sides of the slope 1 along the inclination direction of the slope 1. The top surfaces of the plurality of supporting structures 3 are all arranged horizontally. The two ends of the bottom wall of the green plant module 2 are respectively mounted on the top walls of two supporting structures 3 at the same height. The top wall of the green plant module 2 is flush with the top wall of the supporting structure 3 located above.

[0028] The use of the green plant module 2 can make the entire bank protection structure more visually unified and beautiful. When the green plant module 2 located at the bottom layer is in the flood season, the water level rises and the roots of the plants or the entire plants are immersed in water for a long time, causing hypoxia and respiratory obstruction. The green plant module 2 located at the bottom layer can be pulled out and placed on the top layer, thereby realizing free adjustment of the position of the green plant module 2, which is beneficial to improving the greening life and landscape effect.

[0029] Reference Figure 1 , Figure 3 and Figure 4 The bottom wall of the green plant module 2 is partially fitted with the slope 1, an inclined surface 4 is arranged inside the green plant module 2, the inclination direction of the inclined surface 4 is parallel to the inclination direction of the slope 1, a through groove 5 is arranged at the bottom of the green plant module 2, a covering film 6 is arranged at the bottom of the green plant module 2, and a water permeable hole 7 is arranged on the covering film 6.

[0030] A sand and gravel filter material layer 9 and a rainwater storage module layer 10 are arranged in the green plant module 2 , and the rainwater storage module layer 10 is arranged above the sand and gravel filter material layer 9 .

[0031] The bottom wall of the green plant module 2 is partially in contact with the slope 1, which can increase the stability of the green plant module 2 and avoid the displacement of the green plant module 2 due to natural factors such as wind and rain; the inclined surface 4 in the green plant module 2 can make the green plants more stable during the growth process, and is also beneficial to the discharge of rainwater and the ventilation of the plant roots.

[0032] Reference Figure 1 , Figure 3 and Figure 4 A plurality of guide grooves 8 are arranged on the slope body 1 in the horizontal direction, and the extension direction of the plurality of guide grooves 8 is parallel to the inclination direction of the slope body 1 .

[0033] The setting of the diversion groove 8 can guide the water flow and prevent the water flow from directly eroding the slope 1. It is also beneficial to the discharge of rainwater. The excess water in the green plant module 2 also flows through the water-permeable holes 7 to the through groove 5, and then is discharged into the river through the diversion groove 8.

[0034] The implementation principle of the urban river bank protection structure integrating landscape and ecological functions in the embodiment of the present application is as follows: first, the shape and size of the slope 1 are designed according to the specific conditions of the river, and a number of support structures 3 are evenly arranged on both sides of the slope 1 along the inclination direction of the slope 1; then, according to the height and position of the support structure 3, the green plant module 2 is designed and manufactured so that the two ends of its bottom wall can be erected on the top walls of the two support structures 3 at the same height, and the top wall of the green plant module 2 is flush with the top wall of the support structure 3 located above. When the green plant module 2 located at the bottom layer is in the flood season, the water level rises, causing the roots of the plants or the entire plants to be immersed in water for a long time, causing hypoxia and respiratory obstruction, the green plant module 2 located at the bottom layer can be pulled out and placed on the top layer, realizing the free adjustment of the position of the green plant module 2, which is beneficial to improving the greening life and landscape effect.

[0035] The urban river bank protection structure with integrated landscape and ecological functions of the present invention can not only realize traditional functions such as flood control and scouring prevention, but also add landscape beauty to the urban river and promote the improvement of the ecological environment. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
