Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, specifically to an ecological restoration structure and construction method for rock slopes based on water storage and soil stabilization synergy. Background Technology

[0002] Rock slopes typically refer to slope structures composed of rock with a certain angle of inclination. During engineering construction, mining, road construction, and other activities, numerous rock slopes are often formed. These rock slopes are mostly smooth, lack soil and moisture, and do not provide conditions for vegetation growth. Furthermore, due to their relatively poor stability, rock slopes are prone to safety hazards such as rockfalls, adversely affecting the surrounding ecological environment and human activities.

[0003] Currently, the main methods for treating exposed rock slopes are as follows:

[0004] Traditional hydroseeding involves spraying a mixture of soil, seeds, and fertilizer onto the slope surface to create a soil layer suitable for vegetation growth. However, this technique has several drawbacks. First, the hydroseeded soil layer has poor water retention and is relatively thin. In dry seasons or areas with low rainfall, it is insufficient to provide the vegetation with the necessary moisture, leading to slow growth or even death. Second, the hydroseeded soil layer is easily eroded by rainwater, damaging the vegetation's growing environment and making the remediation effect unsustainable.

[0005] Rigid support structures: These structures use reinforced concrete and other materials to reinforce rock slopes. While they can improve slope stability, this type of structure is incompatible with ecological restoration. Rigid support structures occupy space, restrict the growth range of vegetation, and block rainwater infiltration, hindering water absorption by plant roots and soil retention, thus impeding ecological restoration.

[0006] Slope reduction and gradient lowering projects reduce the danger of slopes by decreasing their height and gradient. However, this method involves a large area of ​​damage and can severely disrupt the existing ecosystem of the mountain. Furthermore, slope reduction and gradient lowering projects require significant investment of funds, manpower, and time, involving a massive amount of work. The construction process may also trigger new geological hazards such as landslides and mudslides, threatening the surrounding environment and the safety of construction workers.

[0007] Stepped planting troughs and floating platforms: These methods primarily avoid large-scale construction on rock faces, creating space for plant growth at specific points. However, these methods are insufficient in water retention capacity, failing to provide adequate moisture for vegetation. They also have structural stability issues, making them unsuitable for the ecological restoration needs of steep rock slopes.

[0008] In summary, existing rock slope treatment technologies suffer from numerous problems, such as poor soil water retention capacity, incompatibility with ecological restoration, large damaged areas, large engineering workload, high costs, and difficulty in achieving lasting treatment effects. Therefore, developing an ecological restoration technology for rock slopes that avoids large-scale construction, has good soil and water conservation capabilities, and is structurally stable is of significant practical importance for improving the ecological environment and ensuring slope safety. Summary of the Invention

[0009] (a) Technical problems to be solved

[0010] To address the shortcomings of existing technologies, this invention provides an ecological restoration structure and construction method for rock slopes based on water storage and soil stabilization synergy. Platforms are uniformly excavated on the rock slope and enclosed with ecological bags to form soil trenches for planting shrubs or small trees. A water storage pond is set up on the platform, and the ecological bags and the water storage pond form a water storage and infiltration channel, constituting a graded water storage and infiltration system. This provides soil and water security for vegetation growth. Simultaneously, the ecological bags are stacked with a gentle outer layer and a steep inner layer, forming a self-stabilizing arch system. The ecological bags are placed on the rock wall, which has sufficient load-bearing capacity. The entire device is highly safe and solves the problems of large-scale earthwork, slow greening effects, suspended installations, and difficulty in maintaining the greening effect in conventional greening technologies.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, the present invention provides the following technical solution: an ecological restoration structure for rock slopes based on water storage and soil stabilization synergy, comprising a rock slope with a smooth inclined structure, wherein the rock slope is an original bare mountain body, and the slope surface of the rock slope is excavated with several platforms, and on each of the several platforms, several ecological bags are stacked to form planting troughs for planting, and the interior of the planting troughs is filled with planting soil for vegetation planting.

[0013] A water storage tank was excavated on the side of the platform near the rock wall, and the inside of the water storage tank was filled with graded crushed stone.

[0014] Preferably, several of the eco-bags are stacked in layers near the edge of the platform, arranged in a two-stretcher-one-twill pattern, with each layer receding approximately 50mm to enhance the stability and firmness of the wall formed by the eco-bags. Furthermore, the eco-bags on the platform are connected and fixed together by fasteners.

[0015] The interior of the ecological bag is filled with planting soil, which is rich in organic matter and contains added nutrients and water-retaining agents.

[0016] Preferably, protective mechanisms are provided on several platforms, which are used to reinforce the wall formed by several eco-bags.

[0017] Preferably, the protective mechanism includes a mesh protective frame, which is fitted and installed on the outer side of a wall formed by several eco-bags.

[0018] Preferably, the planting trough is provided with a water-draining component, which is used to drain rainwater that enters the planting trough.

[0019] When the rainwater inside the planting trough reaches full capacity and can no longer receive rainwater, the excess rainwater is discharged through the hydrophobic component.

[0020] When the rainfall is heavy and the rate at which rainwater seeps into the planting soil is less than the rate at which the planting trough receives rainwater, the excess rainwater is directly channeled into the depths of the planting soil through the hydrophobic components.

[0021] Preferably, the hydrophobic component includes several straight pipes buried in the planting soil, and the several straight pipes are arranged vertically. The top of each of the several straight pipes is provided with a water filter membrane, and the outer surface of the several straight pipes is provided with several through holes. The bottom of the several straight pipes is located inside the water storage tank.

[0022] Preferably, the hydrophobic component further includes a hydrophobic plate fixed to the inner side of the platform, and the hydrophobic plate is located above the planting soil and is used to eliminate the impact force of rainwater during the slope sliding process.

[0023] An overflow frame is fixedly connected inside the platform. The bottom of the overflow frame is pressed against the top of a wall formed by several ecological bags. The overflow frame is filled with filter sand and gravel, and several strip-shaped holes are provided inside the overflow frame.

[0024] The construction method for ecological restoration structures of rock slopes based on water storage and soil stabilization synergy includes the following steps:

[0025] S1. Multiple platforms are uniformly excavated on the surface of the original bare rock slope with a smooth and inclined structure;

[0026] S2. Stack the ecological bags on the platform near the edge, fill the ecological bags with planting soil, and stack them in layers in a two-header-one-stretcher pattern, with each layer receding about 50mm to ensure the stability and firmness of the ecological bag wall.

[0027] S3. Excavate a water storage tank on the side of the platform near the rock wall, and fill the water storage tank with graded crushed stone;

[0028] S4. Fill the space between the ecological bag and the rock slope with planting soil, which is rich in organic matter and contains nutrients and water-retaining agents.

[0029] S5. Sow an appropriate amount of seeds of shrubs such as Caragana korshinskii and Leymus chinensis between each layer of ecological bags, and plant native trees such as Elm and Pinus tabuliformis in the planting troughs formed by the ecological bag enclosure and the rock slope. At the same time, plant Virginia creeper for shade and greening on the side near the rock wall, and plant Forsythia suspensa for hanging greening on the side near the open side, so as to achieve rapid and lasting greening of the slope.

[0030] (III) Beneficial Effects

[0031] Compared with existing technologies, this invention provides an ecological restoration structure and construction method for rock slopes based on water storage and soil stabilization synergy, which has the following beneficial effects:

[0032] This invention involves uniformly excavating platforms on rocky slopes and enclosing them with eco-bags to create soil trenches for planting shrubs or small trees. A water storage pond is set up on the platform, and the eco-bags and the water storage pond form a water storage and infiltration channel, constituting a graded water storage and infiltration system. This provides soil and water security for vegetation growth. At the same time, the eco-bags are stacked in a gentle outer and steep inner manner to form a self-stabilizing arch system. The eco-bags are placed on the rock wall, which has sufficient load-bearing capacity. The entire device is highly safe and overcomes the shortcomings of conventional greening technologies, such as large-scale earthwork, slow greening effect, suspended installation, and difficulty in maintaining the greening effect. It can achieve rapid and long-term greening of steep rock slopes.

[0033] This invention uses several steel ropes to further secure the mesh protective frame, thereby improving the stability of the mesh protective frame in reinforcing the ecological bag wall. This solves the problem of the ecological bag wall tilting and collapsing due to the developed root system of vegetation or excessive rainfall during ecological restoration planting. Moreover, the steel ropes can enhance the protective strength of the mesh protective frame for the wall formed by several ecological bags, replace the initial reinforcement of the planting soil by the tree roots, and be used for the later reinforcement of the tree roots within the planting soil.

[0034] This invention utilizes a snap-fit ​​mechanism consisting of a connecting plate and three sets of positioning shafts. This mechanism facilitates the clamping of three adjacent eco-bags, ensuring the stability of the eco-bag wall. As shown in the attached diagram, the connecting plate of the snap-fit ​​mechanism is positioned between three adjacent eco-bags. The three sets of positioning shafts are then inserted into the interior of the three eco-bags to form a lock, providing a quick and easy assembly and tightening function. The connecting plate is fixed to the mesh protective frame using fastening bolts and two fastening nuts, further enhancing the stability of the eco-bag wall and preventing inward concavity in the eco-bag wall caused by soil erosion in the planting area or by the stepped stacking of the eco-bags, which could compromise the protective function.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1:

[0050] See attached document Figures 1 to 9The ecological restoration structure for rock slopes based on water storage and soil stabilization includes a rock slope 1 with a smooth and inclined structure. The rock slope 1 is the original bare mountain. Several platforms 2 are carved out on the slope surface of the rock slope 1. On each of the platforms 2, several ecological bags 3 are stacked to form planting troughs 4 for planting. The planting troughs 4 are filled with planting soil 5 for planting vegetation. A water storage pool 6 is carved out on the side of the platform 2 near the rock wall. The water storage pool 6 is filled with graded crushed stone 7.

[0051] Platform 2 is evenly excavated on the rock slope 1 and enclosed with ecological bags 3 to form a soil trench for planting shrubs or small trees. A water storage pool 6 is set up on platform 2. The ecological bags 3 and the water storage pool 6 form a water storage and infiltration channel, which constitutes a graded water storage and infiltration system, providing soil and water security conditions for vegetation growth.

[0052] Meanwhile, the ecological bags 3 are stacked in a gentle outer and steep inner manner to form a self-stabilizing arch system. When the ecological bags 3 are placed on the rock wall, the rock wall has sufficient load-bearing capacity, and the whole device is highly safe.

[0053] It overcomes the shortcomings of conventional greening technologies, such as large-scale earthwork, slow greening effect, suspended installation, and difficulty in maintaining the greening effect. It can achieve rapid and long-lasting greening of steep rock slopes.

[0054] By excavating several platforms 2 on the slope surface of the rock slope 1, and by stacking several ecological bags 3 on the platform 2 to form a wall, an ecological restoration planting area can be formed in conjunction with the platform 2, thereby improving the convenience of ecological restoration.

[0055] Compared to traditional ecological restoration methods that involve directly creating planting trenches on the rock slope 1, this method can significantly reduce the difficulty of excavation.

[0056] Compared to the traditional ecological restoration method of directly building walls on platform 2 to form planting trenches, this method can greatly reduce its operation cycle and costs.

[0057] See attached document Figures 2 to 3 Several eco-bags 3 are stacked in layers on the platform 2 near the edge, arranged in a two-stretcher-one-twill pattern, with each layer receding about 50mm to enhance the stability and firmness of the wall formed by the eco-bags 3. The eco-bags 3 on the platform 2 are connected and fixed together by fasteners 10.

[0058] The interior of the ecological bag 3 is filled with planting soil. Both the planting soil 5 and the planting soil are rich in organic mountain soil and contain added nutrients and water-retaining agents to ensure that the soil's viscosity, permeability, nutrients, pH value and other properties meet the requirements for vegetation growth.

[0059] See attached document Figures 1 to 3Each of the platforms 2 is equipped with a protective mechanism 8, which is used to reinforce the wall formed by the multiple eco-bags 3.

[0060] The protective mechanism 8 is used to further enhance the stability of the wall formed by several eco-bags 3, and to prevent the wall from turning outward, thus preventing the failure of ecological restoration.

[0061] See attached document Figures 1 to 3 The protective mechanism 8 includes a mesh protective frame 81, which is attached to the outer side of the wall formed by several eco-bags 3.

[0062] The mesh protective frame 81 is used to attach to the outer side of the wall formed by several ecological bags 3, which not only further reinforces the wall and ensures the stability of the planting area, but also facilitates the drainage of rainwater, thereby preventing the collapse problem caused by excessive water in the planting area when there is a large amount of rain during the rainy season.

[0063] Several steel ropes 82 are fixedly connected to the inner side of the platform 2. One end of each steel rope 82 passes through the wall formed by the ecological bag 3 and is fixed to the mesh protective frame 81.

[0064] By setting up several steel ropes 82, the mesh protective frame 81 is further fixed, thereby improving the stability of the mesh protective frame 81 in reinforcing the ecological bag 3 wall. This solves the problem that the ecological bag 3 wall may tilt and collapse due to the developed root system of the vegetation or excessive rainfall during ecological restoration planting.

[0065] Several steel ropes 82 are used to enhance the protective strength of the mesh protective frame 81 against the wall formed by several ecological bags 3, to replace the reinforcement of the planting soil 5 by the tree root system in the early stage, and to reinforce the tree root system inside the planting soil 5 in the later stage.

[0066] By setting up several steel ropes 82, the protective strength of the mesh protective frame 81 against the wall formed by several ecological bags 3 can be enhanced.

[0067] By setting up several steel cables 82, the roots of the trees and vegetation could not penetrate and anchor properly to the planting soil 5 because they were not deeply developed during the initial planting. The steel cables 82 can replace the roots in penetrating and anchoring the planting soil 5 in the early stage, thereby increasing the shear strength of the soil.

[0068] By setting up several steel ropes 82, the root system in the planting soil 5 can be reinforced in the later stage. Specifically, when the plant grows, its root system will be wrapped with the planting soil 5 and several steel ropes 82 to form a reinforcement, preventing the trees and vegetation from being uprooted and damaged by strong winds during typhoons and other windy seasons. It has good wind and rain resistance performance.

[0069] See attached document Figures 1 to 4 The planting trough 4 is equipped with a water-draining component 9, which is used to drain rainwater that enters the planting trough 4.

[0070] The hydrophobic component 9 is used to manage rainwater during the rainy season, reduce the damage of rainwater to the ecological restoration area, and improve the utilization rate of rainwater in the ecological restoration area.

[0071] When the rainwater inside the planting trough 4 reaches full capacity and can no longer receive rainwater, the excess rainwater is discharged through the drainage component 9 to prevent the water inside the planting trough 4 from carrying mud and sand out when it is full, which would cause soil erosion. In the long run, this could easily lead to the problem of exposed plant roots.

[0072] When the rainfall is heavy and the rate at which rainwater seeps into the planting soil 5 is less than the rate at which the planting trough 4 receives rainwater, the excess rainwater is directly guided into the depths of the planting soil 5 through the drainage component 9. This solves the problem that the planting soil 5 has a high hardness, which leads to low rainwater infiltration efficiency and water leakage before the rainwater has fully infiltrated when the rainfall is heavy. This method is suitable for use in the event of intermittent heavy rain.

[0073] The construction method for ecological restoration structures of rock slopes based on water storage and soil stabilization synergy includes the following steps:

[0074] S1. Multiple platforms 2 are uniformly excavated on the surface of the original bare rock slope 1, which has a smooth and inclined structure;

[0075] First, it is necessary to completely remove the dangerous rocks on the slope. On the rock slope 1, a platform 2 should be excavated. The platform 2 should be no less than 2m*2m in size and the angle between the platform 2 and the rock mass should not be greater than 75°. It should be naturally exposed on the original slope line. The platforms should be spaced 4m*4m apart and arranged in a quincunx pattern. Alternatively, the original micro-topography platform 2 of the rock slope 1 can be used to enclose soil bags, store soil in troughs, and plant trees and shrubs for revegetation.

[0076] S2. Stack the ecological bags 3 in layers near the edge on platform 2. The ecological bags 3 are made of 200g / m² product with a size of 840mm×400mm. The ecological bags 3 are filled with planting soil, and the size after filling with soil is 600mm×300mm×150mm. The ecological bags 3 are connected by buckles 10 and stacked in layers in a two-stretcher-one-header manner, with each layer receding about 50mm to ensure the stability and firmness of the ecological bag wall.

[0077] S3. Excavate a water storage tank 6 on the side of platform 2 near the rock wall. The water storage tank 6 is about 20cm deep and has an area of ​​not less than 1 square meter. The water storage tank 6 is filled with graded crushed stone 7. Specifically, after laying HDPE composite waterproof board at the bottom of the tank, graded crushed stone 6 is filled in layers, a leveling fine stone layer is laid and covered with filter non-woven fabric.

[0078] S4. Fill the space between the ecological bag 3 and the rock slope 1 with planting soil 5. The planting soil 5 is rich in organic matter and contains nutrients and water-retaining agents to ensure that the soil viscosity, permeability, nutrients, pH value and other properties meet the requirements for vegetation growth.

[0079] S5. Sow an appropriate amount of seeds of shrubs such as Caragana korshinskii and Leymus chinensis between each layer of ecological bags 3, and plant native trees such as elm and Pinus tabuliformis in the planting troughs formed by the ecological bag 3 enclosure and the rock slope 1. At the same time, plant Virginia creeper for shade and greening on the side near the rock wall, and plant Forsythia suspensa for hanging greening on the side near the open side, so as to achieve rapid and lasting greening of the slope.

[0080] Example 2: The difference from Example 1 is that;

[0081] See attached document Figures 1 to 4 The hydrophobic component 9 includes several straight pipes 91 buried in the planting soil 5, and the several straight pipes 91 are arranged vertically. The top of each of the several straight pipes 91 is provided with a filter membrane 92, and the outer surface of the several straight pipes 91 is provided with several through holes 93. The bottom of the several straight pipes 91 is located inside the water storage tank 6.

[0082] The top of the straight pipe 91 is slightly higher than the top surface of the planting soil 5, and the top of the straight pipe 91 is lower than the height of the wall of the ecological bag 3. This allows the rainwater to enter the water storage tank 6 directly through the straight pipe 91 when the rainwater accumulates on the top of the planting soil 5 and is higher than the straight pipe 91, so that the rainwater can be used quickly and the problem of rainwater waste can be prevented. When draining water through the straight pipe 91, the water can enter different layers of the planting soil 5 through several through holes 93, further increasing the rainwater infiltration effect.

[0083] The drainage component 9 also includes a drainage plate 94 fixed to the inner side of the platform 2, and the drainage plate 94 is located above the planting soil 5 and is used to eliminate the impact force of rainwater during the slope sliding process.

[0084] The drainage plate 94 is used to receive rainwater during the slope sliding process, and prevents the water source from creating holes in the planting soil 5 when the impact force of the high-speed flowing water is large, which would lead to the problem of exposed roots.

[0085] The platform 2 is fixedly connected to an overflow frame 95. The bottom of the overflow frame 95 is pressed against the top of the wall formed by several ecological bags 3. The overflow frame 95 is filled with filter sand and gravel, and the overflow frame 95 has several strip holes inside.

[0086] By filling the interior of the overflow frame 95 with filter sand and gravel, the overflow frame 95 can block water and soil when there is sufficient water, and filter rainwater, so that rainwater will not carry soil when it is discharged, thus ensuring the integrity of the planting soil 5.

[0087] Example 3: The difference from Example 1 is that;

[0088] See attached document Figures 5 to 7 The fastener 10 includes a connecting plate 101. A row of positioning shafts 102 are fixedly connected to both sides of the top and the bottom of the connecting plate 101. A through hole 103 is opened inside the connecting plate 101, and a fastening bolt rod 104 is inserted into the through hole 103. Fastening nuts 105 are threaded on both ends of the fastening bolt rod 104. The connecting plate 101 is fixedly connected to the mesh protective frame 81 through the fastening bolt rod 104 and the two fastening nuts 105.

[0089] The fastener 10, consisting of a connecting plate 101 and three sets of positioning shafts 102, facilitates the clamping of three adjacent eco-bags 3, ensuring the stability of the eco-bag 3 wall. Specific operation instructions are attached. Figure 6 As shown, the connecting plate 101 of the buckle 10 is placed between three adjacent ecological bags 3, and the three sets of positioning shafts 102 are inserted into the interior of the three ecological bags 3 to form a lock, which has the function of quick assembly and locking, and improves the convenience of operation.

[0090] The connecting plate 101 is fixedly connected to the mesh protective frame 81 by fastening bolts 104 and two fastening nuts 105, which facilitates further improvement of the stability of the ecological bag 3 wall and prevents the ecological bag 3 wall from easily becoming concave due to soil erosion in the planting area and the step-like stacking of the ecological bag 3 wall, thus losing the wall protection.

[0091] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
