Description

Technical Field

[0001] This utility model relates to the field of ecological revetment technology, and more specifically, to a combined ecological restoration revetment structure. Background Technology

[0002] The existing natural waterways and artificially channelized waterways generally face the following comprehensive problems: Poor hydrological stability: Affected by seasonal rainfall and floods, river levels fluctuate rapidly between drought and flood. During the flood season, the water flow erodes the riverbanks severely, causing soil erosion and shoreline retreat; during the dry season, large areas of the riverbed are exposed, and habitats dry up. Ecological degradation: Unstable hydrological conditions and a monotonous physical structure lead to sparse and homogeneous riparian plant communities with weak root systems that cannot effectively resist erosion. Furthermore, the lack of diverse habitats makes it difficult to support a variety of aquatic and terrestrial organisms, resulting in low biodiversity and a fragile food chain.

[0003] Traditional engineering drawbacks: Although the rigid revetments (such as concrete slope protection) used in the past can prevent floods and resist erosion, they sever the connection between water and land ecology, exacerbate ecological degradation, and have a rigid shape, lack water accessibility, and cannot meet the ecological and landscape requirements of modern cities for waterfront spaces.

[0004] Therefore, current governance efforts have shifted towards seeking solutions that harmonize safety, ecology, and accessibility to water. However, a single form of ecological revetment often struggles to meet the complex needs of different sections of the river. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a combined ecological restoration revetment structure. This revetment structure constructs a revetment system that integrates stable protection, ecological restoration, and landscape creation, effectively overcoming the drawbacks of traditional hard revetments, such as weak ecological function and monotonous landscape effect.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A combined ecological restoration revetment structure includes a gabion retaining wall, geotextile, a first landscape stone, a second landscape stone, scattered riverbed stones, a crushed stone cushion layer, a concrete cushion layer, a topsoil layer, and a vegetation layer. The gabion retaining wall is a retaining wall structure made of metal mesh and filled with boulders; the geotextile is placed on the back side of the gabion retaining wall; the first landscape stone is arranged in the upper area of ​​the gabion retaining wall; the second landscape stone is arranged at intervals with the first landscape stone; the scattered riverbed stones are arranged in the area between the first landscape stone and the second landscape stone; the crushed stone cushion layer and the concrete cushion layer are arranged in sequence below the second landscape stone; the second landscape stone is surrounded by the planting soil layer, and the vegetation layer is arranged on the planting soil layer.

[0007] The gabion retaining wall is composed of at least two layers of gabion units stacked from bottom to top, and the width of the upper gabion unit is smaller than the width of the lower gabion unit.

[0008] The gabion unit is filled with stones with a particle size of 100mm to 250mm.

[0009] The uppermost gabion unit has a height of 100mm to 300mm below the normal water level.

[0010] The distance between the first scenic stone and the second scenic stone is 3 to 10 meters.

[0011] A compacted slope is formed in the area between the first scenic stone and the second scenic stone, and the scattered riverbed stones are placed on the compacted slope, with a particle size of 50mm to 150mm.

[0012] The vegetation layer includes a variety of aquatic and terrestrial plants.

[0013] The revetment structure can be implemented in at least one of the following forms: a combination of gabion retaining walls and vegetation layers, a combination of gabion retaining walls and first and second landscape stones, or a combination of first and second landscape stones and vegetation layers.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By systematically integrating engineering protective structures such as gabion retaining walls and geotextiles with ecological landscape elements such as scenic stones, vegetation, and scattered riverbed stones, a revetment system integrating stable protection, ecological restoration, and landscape creation has been creatively constructed, effectively overcoming the shortcomings of traditional hard revetments, such as weak ecological function and monotonous landscape effect. The presence of a gabion layer below the water surface, a scattered riverbed stone area, and a diverse vegetation layer provides valuable habitats and refuges for aquatic organisms and insects. The establishment of plant communities promotes root stabilization, absorption of nutrients from the water, and purification of water quality, thereby effectively restoring and enhancing the biodiversity and self-purification capacity of the river channel. The use of multi-layered terraced gabion retaining walls as the core support structure not only provides good overall stability and strong erosion resistance, but also allows for better adaptation to slight foundation deformation due to its flexibility. The combination of rubble filling and geotextile filter layer ensures smooth drainage within the structure, effectively preventing soil erosion and bank collapse, and significantly improving the long-term safety and durability of the revetment.

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 4 As shown, a modular ecological restoration revetment structure includes a gabion retaining wall 1, geotextile 3, a first landscape stone 4, a second landscape stone 8, scattered riverbed stones 5, a crushed stone cushion layer 6, a concrete cushion layer 7, a soil layer 9, and a vegetation layer 10. These components, through scientific combination and layout, together constitute a functionally integrated ecological restoration system.

[0019] The gabion retaining wall 1, as the core protective structure, is composed of metal mesh boxes filled with rubble 2. In a preferred embodiment, the gabion retaining wall 1 is constructed by stacking at least two layers of gabion units from bottom to top, forming a stepped structure, where the width of the upper gabion unit is smaller than the width of the lower gabion unit. This stepped design significantly enhances the overall stability and erosion resistance of the retaining wall. The rubble 2 used for filling is preferably hard, weather-resistant stone, with a particle size range controlled between 100mm and 250mm to ensure the density and structural strength of the gabions.

[0020] Preferably, geotextile 3 is tightly laid on the back side of the gabion retaining wall 1, that is, the side closest to the bank slope soil. Geotextile 3 is preferably a reverse filter type geotextile, whose core function is to prevent soil erosion on the bank slope, while allowing groundwater to drain smoothly and avoiding the accumulation of water pressure on the back side, thus playing a key role in water permeability and soil conservation.

[0021] In terms of landscape design, a first scenic stone 4 is placed above the gabion retaining wall 1. The first scenic stone 4 and the second scenic stone 8 downstream are set at intervals, and the net distance between them can be adjusted within the range of 3 to 10 meters according to the meandering shape of the riverbank and the visual landscape requirements, thereby breaking the monotony of the revetment landscape.

[0022] Preferably, in the area between the first scenic stone 4 and the second scenic stone 8, the slope surface is first prepared and compacted to form a gentle slope. Scattered riverbed stones 5 are placed on this compacted slope surface. The particle size of these pebbles 5 is preferably 50mm to 150mm. They not only enhance the slope's resistance to erosion, but their natural appearance also blends into the surrounding environment, enriching the texture of the shoreline.

[0023] Preferably, the second landscape stone 8, as another important landscape node, is arranged more stably. Beneath it, from bottom to top, are a gravel cushion layer 6 and a concrete cushion layer 7, which together form a solid supporting foundation, ensuring the long-term stability of the second landscape stone 8. Around the second landscape stone 8, a layer of planting soil 9 of appropriate thickness is laid.

[0024] Preferably, a vegetation layer 10 is provided on top of the soil layer 9. This vegetation layer 10 is the main embodiment of ecological restoration, and it is composed of a variety of aquatic and terrestrial plants adapted to the local environment. The selection of plant species fully considers their water-resistance, root system for soil stabilization, and landscape ornamentation characteristics, thereby forming a self-sustaining plant community that greatly enhances the biodiversity and ecological value of the river channel.

[0025] Preferably, the uppermost gabion unit's upper surface should be positioned below the normal water level, with the height below the normal water level controlled between 100mm and 300mm. This design allows the gabion retaining wall to function as a wave absorber at the normal water level, while the gaps on it provide habitats for aquatic organisms, further enhancing the structure's ecological function.

[0026] Preferably, the revetment structure can be implemented in at least one of the following forms: a combination of gabion retaining wall 1 and vegetation layer 10; a combination of gabion retaining wall 1 and first landscape stone 4 and second landscape stone 8; or a combination of first landscape stone 4, second landscape stone 8 and vegetation layer 10.

[0027] To adapt to different river conditions and landscape requirements, the revetment structure described in this utility model can be implemented in various combinations. For example, it can form such as... Figure 2 The "gabion retaining wall 1 + vegetation layer 10 revetment" shown emphasizes simplicity and ecology; or as... Figure 3 The "gabion retaining wall 1 + first scenic stone 4, second scenic stone 8 revetment" shown emphasizes the integration of structure and landscape; it can also form a structure like... Figure 4 The "first scenic stone 4, second scenic stone 8 + vegetation layer 10 revetment" shown highlights the natural landscape effect. This diverse combination capability allows this utility model to be flexibly applied to various complex river regulation and ecological restoration projects.

[0028] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
