Description

Technical Field

[0001] This utility model relates to the field of slope stabilization planting technology, specifically an ecological bank protection method based on tree root systems for slope stabilization. Background Technology

[0002] Currently, traditional riverbank protection structures are mostly constructed using hard materials such as concrete and masonry. While they possess a certain degree of erosion resistance and structural stability, they are significantly lacking in ecological benefits. These types of bank protection structures disrupt the natural connection between the river and the bank slope, leading to a decline in the water's self-purification capacity, loss of biological habitats, and an unnatural visual appearance that is difficult to harmonize with the surrounding natural environment.

[0003] While existing ecological bank protection technologies have included attempts to use vegetation for slope protection, most remain at the level of surface greening or simply planting herbaceous plants. These plants have shallow root systems and limited soil-stabilizing capabilities, making them unsuitable for long-term effective resistance to water erosion and slope slippage. Particularly in areas with fluctuating water levels and at the toe of the slope, plant survival rates are low, making it difficult to guarantee the effectiveness of bank protection. Furthermore, current technologies lack sufficient measures for guiding and securing plant roots, resulting in poor overall integrity and durability of the bank protection structure, and failing to form a stable and sustainable ecological bank protection system.

[0004] To address the problems raised in the background art, those skilled in the art have proposed an ecological bank protection method based on tree root systems for slope stabilization. Summary of the Invention

[0005] The purpose of this utility model is to provide a new type of ecological revetment based on tree root system stabilization, which ensures the stability of the revetment while also having ecological restoration functions, strong environmental adaptability and simple construction, so as to solve the problem that it is difficult to balance ecological and structural aspects in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ecological bank protection system based on tree root system for slope stabilization, including a riverbank embankment, one side of which is provided with a side guard plate for connecting with the river water, the inner side of which is planted with soil-stabilizing tree species, and the inner wall of which is provided with a fixing component for fixing the soil-stabilizing tree species.

[0007] Ecological bags are also installed on the inner side of the riverbank embankment to degrade organic waste in the soil, and anchoring structures are also installed inside the side guard plate to enhance the overall stability of the bank protection.

[0008] Preferably, the fixing components include shallow root reinforcement and deep root anchoring, which are installed in two layers inside the riverbank embankment to fix the root system of the soil-stabilizing tree species in layers.

[0009] Preferably, galvanized catalpa netting and geotextile netting are also provided between the side guard plate and the riverbank embankment to enhance the erosion resistance of the bank edge and prevent soil erosion.

[0010] Preferably, the anchoring structure includes multiple sets of horizontally and vertically intersecting binding steel bars, which are placed on the inner side of the side retaining plate, and soil stabilization anchors are provided at their joints to enhance the integrity and stability of the revetment structure.

[0011] Preferably, the eco-bag is made of biodegradable material and filled with an organic matrix that promotes microbial growth, thereby accelerating the decomposition of organic matter in the soil.

[0012] Preferably, the root system of the soil-stabilizing tree species, together with the fixing components, galvanized netting, and geotextile netting, forms a composite soil-stabilizing system, enhancing the ecological stability and erosion resistance of the revetment.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, by setting up a layered fixing component that combines shallow root reinforcement and deep root anchoring, can effectively guide and fix the root development of soil-stabilizing tree species, significantly enhance the integrity and shear resistance of the root-soil composite, thereby improving the structural stability and erosion resistance of the revetment.

[0015] 2. This utility model effectively strengthens the protection of the bank edge and reduces soil erosion by setting galvanized catalpa netting and geotextile coconut netting between the side protection plate and the riverbank embankment. At the same time, its porous structure provides space for plant root growth, which is conducive to the function of ecological functions.

[0016] 3. By adopting an anchoring structure with built-in reinforcing steel bars and soil anchoring, this utility model significantly enhances the overall rigidity and stability of the side protection plate, enabling it to better resist water flow impact and lateral soil pressure, and extending the service life of the revetment.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1: This utility model provides an ecological bank protection based on tree root system for slope stabilization, including a riverbank embankment 1. A side guard plate 2 is provided on one side of the riverbank embankment 1 for connecting with the river water. Soil-stabilizing tree species 3 are planted on the inner side of the riverbank embankment 1. A fixing component is provided on the inner wall of the riverbank embankment 1 for fixing the soil-stabilizing tree species 3.

[0027] Ecological bags 21 are also installed on the inner side of the riverbank embankment 1 to degrade organic waste in the soil, and anchoring structures are also provided in the side guard plate 2 to enhance the overall stability of the bank protection.

[0028] During the work, the workers first installed the prefabricated side protection panels 2 onto the water-facing side of the riverbank embankment 1 using anchoring structures, and then backfilled the inner side of the embankment 1 with planting soil suitable for the growth of soil-stabilizing tree species 3 in layers. Subsequently, the soil-stabilizing tree species 3 were planted at the designated locations, and their root systems were initially fixed and guided using fixing components. Finally, ecological bags 21 were placed on the slope and root area. Through the above steps, a collaborative bank protection system guided by the engineering structure and actively reinforced by plant roots was constructed. This system can not only effectively resist water erosion and soil slippage, but also continuously improve the soil environment through ecological bags, achieving a unity of bank protection structural stability and ecological health.

[0029] 1. In one embodiment of the present invention, the fixing component includes shallow root reinforcement 11 and deep root anchoring 12, which are respectively installed in the upper and lower layers of the riverbank embankment 1 for layered fixing of the root system of the soil-stabilizing tree species 3.

[0030] During the work, workers first lay a mesh or grid-like shallow root reinforcement 11 in the upper soil layer to restrain and guide the lateral expansion of the shallow roots of the soil-stabilizing tree species 3, forming a reinforcement mesh. Then, pile-like or tubular deep root anchors 12 are buried in the lower soil layer to guide the main roots to penetrate deeply downwards. This layered fixing method effectively utilizes the different growth characteristics of tree roots, transforming the shallow root system into a reinforcement mesh and the deep root system into anchor piles. This greatly enhances the pull-out resistance and shear strength of the root system and soil composite, thereby significantly improving the deep stability of the slope.

[0031] 2. In one embodiment of this utility model, a galvanized wire mesh 22 and a geotextile mesh 23 are also provided between the side guard plate 2 and the riverbank embankment 1 to enhance the erosion resistance of the bank edge and prevent soil erosion.

[0032] During the work, before installing the side retaining plate 2, the workers first laid geotextile coconut mesh 23 and galvanized catalpa mesh 22 in layers at the interface between the side retaining plate 2 and the soil of the riverbank embankment 1. The geotextile coconut mesh 23 is close to the soil, and its natural fiber structure promotes the entanglement of fine roots and the attachment of microorganisms; the outer galvanized catalpa mesh 22 provides higher tensile strength and erosion resistance. Through the combined use of these two materials, a flexible reinforcing strip is formed at the edge of the revetment, which can effectively disperse the impact of water flow and prevent the soil at the bank edge from being eroded. Its porous structure also provides a channel for plant roots to penetrate, realizing the combination of engineering protection and ecological function, and effectively preventing soil erosion in the long term.

[0033] 3. In one embodiment of the present invention, the anchoring structure includes multiple sets of horizontally and vertically intersecting binding steel bars 25. The binding steel bars 25 are arranged on the inner side of the side guard plate 2, and soil stabilizing anchors 24 are provided at their joints to enhance the integrity and stability of the revetment structure.

[0034] During the construction process, workers first embed multiple sets of steel bars 25, tied in a cross pattern of horizontal and vertical lines, inside the concrete of the side retaining plate 2. At all the cross points of the steel bars, soil anchorage 24 is installed using welding or special fasteners. This dense internal steel reinforcement framework greatly enhances the structural rigidity and integrity of the side retaining plate 2, enabling it to effectively transfer the soil pressure and water flow impact through the anchorage points to the stable soil behind it. This prevents deformation, displacement, or overturning of the retaining plate itself, ensuring the long-term stability and safety of the waterfront revetment structure.

[0035] 4. In one embodiment of the present invention, the ecological bag 21 is made of biodegradable material and is filled with an organic matrix that promotes the growth of microorganisms, thereby accelerating the decomposition of organic matter in the soil.

[0036] During the process, workers first lay eco-bags 21 filled with organic substrates such as straw, sawdust, and humus on the slopes surrounding the root zone of the soil-stabilizing tree species 3. The biodegradable outer shell of the eco-bags 21 gradually decomposes under the influence of soil moisture and microorganisms, releasing the internal organic substrate and mixing it with the surrounding soil. This process not only provides abundant carbon and nutrients for soil microorganisms, promoting their proliferation, but also accelerates the decomposition and transformation of residual organic waste (such as plant debris and organic pollutants) in the soil, thereby continuously improving the soil environment in the root zone and creating favorable conditions for the healthy growth of the soil-stabilizing tree species 3.

[0037] 5. In one embodiment of this utility model, the root system of the soil-stabilizing tree species 3, together with the fixing component, the galvanized net 22, and the geotextile net 23, forms a composite soil-stabilizing system, which enhances the ecological stability and erosion resistance of the revetment.

[0038] During the process, workers first select and plant native soil-stabilizing tree species 3 with well-developed root systems and strong adaptability. Guided by the fixing components (shallow root reinforcement 11, deep root anchoring 12), their roots penetrate deeply and spread horizontally, forming a natural reinforced anchoring network. Simultaneously, some roots penetrate and entwine with the geotextile coconut netting 23 and galvanized catalpa netting 22, tightly integrating with these engineering materials. Through the life activities of the plant roots, the originally independent engineering structures (fixing components, netting materials) are organically linked to the soil into a unified, dynamic composite soil-stabilizing system. This system not only provides immediate strength through the engineering materials but also provides continuously enhanced anchoring force and erosion resistance through the constantly growing and strengthening root network, achieving long-term synergistic effects on the ecological benefits and engineering stability of the revetment structure.

[0039] Working principle: In actual use, the planted crop is anchored by shallow root reinforcement 11 and deep root anchoring 12 to fix its root system. The root system helps to fix the soil. The geotextile netting 23, galvanized netting 22 and soil anchoring 24 set in the side guard plate 2 also play a certain role in fixing the soil.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
