Description

Technical Field

[0001] The invention relates to the technical field of slope protection, in particular to an ecological slope protection structure for a fissured rock mass slope, aiming to improve the stability of the slope and promote the ecological restoration of the slope. Background Art

[0002] In the field of slope protection, the stability of fractured rock slopes has always been an urgent problem to be solved. Fractured rock mass is vulnerable to external factors such as rain erosion, wind erosion, earthquakes and other natural forces due to its developed internal fissures and loose structure, which can lead to slope instability, landslides, mudslides and other natural disasters, posing a serious threat to people's lives and property.

[0003] Traditional slope protection methods mostly use single engineering measures, such as building retaining walls and spraying slope protection. Although these methods can improve the stability of the slope to a certain extent, they have many shortcomings. For example, a single retaining wall structure is often unable to withstand the huge earth pressure generated by the long-distance slope surface, which can easily lead to local damage; at the same time, traditional slope protection methods often ignore the importance of ecological restoration, causing the slope to lose its original ecological function during the protection process, which is not conducive to the sustainable development of the ecological environment.

[0004] Therefore, there is an urgent need for an ecological slope protection technology for fractured rock slopes. This technology should be able to fully utilize the advantages of engineering measures and ecological restoration to form a stable protection system, while promoting the ecological restoration of the slope and achieving slope stability and sustainable development. Summary of the invention

[0005] The purpose of the present invention is to provide an ecological slope protection for a fractured rock mass slope, aiming to improve the stability of the fractured rock mass slope and promote the ecological restoration of the slope.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: An ecological slope protection for a fractured rock mass slope, comprising: A plurality of retaining walls are erected on the slope, wherein the bottom of each retaining wall is buried below the slope surface; An upper reinforcement net, which covers the slope and is lifted up by the retaining walls on each side. The upper reinforcement net located between two adjacent retaining walls hangs down until it contacts the slope. The upper reinforcement net has a wavy structure as a whole and is fixed to the retaining walls and the slope. A lower reinforcement net, the lower reinforcement net having an overall wave-like structure, wherein the trough end is buried below the slope surface and pressed below the bottom end of the retaining wall, and the crest end protrudes above the slope surface between the two adjacent retaining walls and is fixed to the upper reinforcement net; Plant seeds are sown on the slope between the retaining walls.

[0007] In some embodiments, the top connecting line or the bottom connecting line of each retaining wall is consistent with the extension direction of the slope.

[0008] In some embodiments, the retaining wall is a trough-like structure with an open top, a planting cavity is left inside the retaining wall, and the planting cavity is filled with planting soil.

[0009] In some embodiments, a plurality of through openings are formed through the bottom of the implant cavity.

[0010] In some embodiments, a reinforcement wall is provided between each two adjacent retaining walls.

[0011] In some embodiments, the reinforcement wall is in an arch shape, the top of the arch structure faces the retaining wall at a higher position, and two arch feet are both against the retaining wall at a lower position.

[0012] In some embodiments, the lower reinforcement net protruding above the slope between two adjacent retaining walls is fixed to the upper reinforcement net by a plurality of positioning nails.

[0013] In some embodiments, the plant seeds are herbaceous plant, shrub or tree seeds.

[0014] In some embodiments, both the upper reinforcement web and the lower reinforcement web are kept in a relaxed state.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention divides a long slope into multiple shorter sections by erecting multiple retaining walls built on the slope, so that the pressure on each section of the slope is more uniform, avoiding local damage caused by concentrated pressure. The setting of the multiple retaining walls forms a layer-by-layer progressive support system, and the external pressure is gradually dissipated and absorbed during the transmission process, further enhancing the stability of the slope. In addition, the upper reinforcement net and the lower reinforcement net are combined with the multiple retaining walls to jointly construct a three-dimensional protection system, which effectively improves the overall disaster resistance of the slope system.

[0016] The present invention sows plant seeds on the slope surface, and utilizes the growth of plants and the reinforcement net to form an entangled structure. This synergistic effect not only reinforces the plants themselves to prevent them from being damaged by natural disasters, but also enhances the stability of the slope through the growth activities of the plants. As the plants grow, their stems, leaves and roots form a complex ecological network structure with the reinforcement net. This network helps to prevent soil erosion and landslide disasters on the slope by increasing the soil's anti-scouring ability and promoting soil and water conservation. The growth of plants can also penetrate and restrain unstable parts in the fractured rock mass, thereby increasing the integrity and stability of the rock mass. At the same time, the combined effect of the reinforcement net and the plant layer can also enhance the fractured rock mass's anti-weathering and anti-erosion ability, thereby extending its service life.

[0023] See also Figure 1-6 This embodiment provides an ecological slope protection for a fractured rock mass slope, including: Multiple retaining walls 1 are erected on the slope, and the bottom of each retaining wall 1 is buried below the slope surface. By setting multiple retaining walls 1 on the slope surface, the long slope surface is divided into multiple shorter sections. This can make the pressure on each section of the slope surface more uniform, avoiding local damage caused by concentrated pressure. The setting of multiple retaining walls 1 also forms a layered support system, so that the external pressure is gradually dissipated and absorbed during the transmission process, further enhancing the stability of the slope; Flexible upper reinforcement net 3 and lower reinforcement net 4, the upper reinforcement net 3 covers the slope surface and is lifted up by the retaining walls 1 on each side, the upper reinforcement net 3 located between two adjacent retaining walls 1 hangs down to contact the slope surface, the upper reinforcement net 3 is in a wavy structure as a whole, the upper reinforcement net 3 and the retaining wall 1 and the slope surface are all fixed, the lower reinforcement net 4 is in a wavy structure as a whole, the trough end of which is buried below the slope surface and pressed under the bottom end of the retaining wall 1, and the crest end protrudes above the slope surface between the two adjacent retaining walls 1 and is fixed to the upper reinforcement net 3; Plant seeds are sown on the slope between the retaining walls 1. The introduction of plant seeds allows the stems, leaves and roots of the plants that grow subsequently to be entangled with the reinforcement net. This synergistic effect not only reinforces the plants themselves to prevent them from being damaged by natural disasters, but also enhances the stability of the slope through the growth activities of the plants. As the plants grow, their stems, leaves and roots form a complex ecological network structure with the reinforcement net. This network helps prevent soil erosion and landslide disasters on the slopes by increasing the soil's ability to resist scour and promoting soil and water conservation. Such a dense and complex network structure can penetrate and restrain the unstable parts in the fractured rock mass, increase the integrity and stability of the rock mass, and the combined effect of the reinforcement net and the plant layer can also enhance the weathering and erosion resistance of the fractured rock mass and extend its service life.

[0024] In the present invention, the upper reinforcement net 3 and the lower reinforcement net 4 are combined with the multi-faceted retaining wall 1 to jointly construct a three-dimensional protection system. This system not only provides stable support in the horizontal direction, but also enhances the overall stability of the slope in the vertical direction through the deep burial of the retaining wall 1 and the coverage of the reinforcement net. The upper reinforcement net 3 and the lower reinforcement net 4 are fixed on the slope at multiple points, and can also resist the impact force along the slope surface. Specifically, the upper reinforcement net 3 and the lower reinforcement net 4 are tensioned and fixed in the extension direction of the slope surface to form a protective barrier that is close to the slope surface. These reinforcement nets have high tension and durability and can withstand various stresses of the external environment, such as wind force, water flow scouring force, etc. The reinforcement net is fixed on the slope surface and the retaining wall 1 at multiple points to ensure that uniform and continuous support can be provided throughout the entire slope surface. This fixing method effectively prevents the displacement of the reinforcement net, thereby maintaining the integrity of the protection system.

[0025] The reinforcement net is preferably made of high-strength material with excellent durability and impact resistance. Its wavy structural design increases the flexibility and buffering capacity of the material, so that the slope can more effectively disperse and absorb the impact force when facing external impact. This structure can deform when subjected to external impact, thereby absorbing and buffering the impact force, and this buffering effect helps to reduce the damage to the slope caused by natural disasters such as landslides and mudslides. The wavy structure also has good elastic recovery ability, and can quickly return to its original state even after a large impact, and continue to play a protective role.

[0026] Moreover, the upper reinforcement net 3 and the lower reinforcement net 4 are fixed on the retaining wall 1 at multiple points, which significantly enhances the structural stability of the retaining wall 1. Specifically, the reinforcement net can effectively disperse the soil pressure and external impact force borne by the retaining wall 1, preventing the retaining wall 1 from being damaged due to uneven force. The combination of the reinforcement net and the retaining wall 1 makes the entire slope protection structure form a stable whole, thereby improving the overall disaster resistance of the slope system.

[0027] In addition, as a flexible material, the reinforcement net can deform and absorb part of the kinetic energy when impacted by falling rocks, thereby reducing the destructive power of falling rocks on the slope. The densely grown plant layer can also play a certain buffering role, reducing the direct contact and impact between falling rocks and the slope.

[0028] In summary, the present invention forms a stable three-dimensional support system through the combination of the upper reinforcement net 3, the lower reinforcement net 4 and the multi-faceted retaining wall 1. This system can effectively disperse the external pressure and improve the stability of the slope. Secondly, by sowing plant seeds on the slope, the growth of plants and the reinforcement net form an entangled structure, which further enhances the stability of the slope. This artificial and natural reinforcement system can not only resist the impact of natural disasters, but also promote the ecological restoration of the slope, forming a sustainable and self-repairing slope protection system.

[0029] In some embodiments, Figure 4 As shown, the top or bottom connection line of each retaining wall 1 is consistent with the extension direction of the slope. First, when the top or bottom connection line of the retaining wall 1 is consistent with the extension direction of the slope, the entire slope protection structure is more coordinated visually, giving people a neat and unified aesthetic feeling. This design not only improves the practicality of the slope protection, but also takes into account the aesthetics. In addition, such a design can also ensure the uniformity and continuity of the force during the transmission process, avoiding the stress concentration phenomenon caused by structural incoordination.

[0030] In some embodiments, Figure 4 As shown in Figure 6, the retaining wall 1 is a trough-shaped structure with an opening at the top, and a planting cavity 101 is left inside. The planting cavity 101 is filled with planting soil. The planting soil in the planting cavity 101 provides a direct growth matrix for the plants, promotes the healthy growth of the plants, increases the vegetation coverage of the slope, and improves the diversity and stability of the ecosystem. The retaining wall 1 with a trough-shaped structure, the filled planting soil and the growing plants together form an integrated ecological slope protection system, which enhances the integrity and continuity of the slope protection structure, and the presence of the planting soil and plants also plays a buffering role, which can absorb and disperse part of the impact force and reduce the risk of slope damage.

[0031] In addition, since the upper reinforcement net 3 covers the slope surface and is supported by the retaining walls 1, when the plants planted in the retaining wall 1 grow, their stems and leaves will naturally extend and entangle with the upper reinforcement net 3. This entangled structure not only reinforces the plants themselves to prevent them from being easily damaged by natural disasters (such as wind, rain, snow, etc.), but also forms a tighter and more stable protective layer through the mutual entanglement of the stems and leaves of the plants and the reinforcement net. The combination of the stems and leaves of the plants and the reinforcement net enhances the ability of the slope to resist external impact force, because the stems and leaves of the plants can absorb and disperse part of the impact force, while the reinforcement net provides additional support and fixation.

[0032] Preferably, Figure 4 As shown in Fig. 6, a plurality of through-holes 102 are provided at the bottom of the planting cavity 101. The through-holes 102 allow rainwater and irrigation water to quickly drain out of the planting cavity 101, effectively preventing water from accumulating in the planting cavity 101, and avoiding plant root rot or soil oversaturation caused by excessive water. Good drainage performance ensures the healthy growth of plant roots and improves the survival rate and growth quality of plants. The through-holes 102 also provide a direct contact channel between the soil in the planting cavity 101 and the rock mass below, promoting material exchange and microbial activity between the soil and the rock mass. This interaction helps to enhance the bonding between the soil and the rock mass and improve the overall stability of the slope.

[0033] In addition, the plant roots can extend below the slope through the through hole 102 and be entangled with the lower reinforcement net 4 pressed at the bottom of the retaining wall 1. The combination of the plant roots and the lower reinforcement net 4 forms a three-dimensional support network, which can disperse and absorb the stress on the slope and reduce the risk of local damage. At the same time, this combination also enhances the overall continuity of the slope, making the slope more stable in the face of natural disasters. Moreover, the entanglement of the plant roots with the lower reinforcement net 4 not only reinforces the plants themselves, but also enhances the stability of the reinforcement net through the growth activities of the plants. This synergistic effect makes the ecological slope protection system more tough and durable, and can maintain the stability of the slope for a long time.

[0034] In some embodiments, Figure 2 As shown, a reinforcement wall 2 is built between each two adjacent retaining walls 1. The reinforcement wall 2 enhances the integrity and continuity of the entire slope protection structure. It makes the multiple retaining walls 1 no longer isolated individuals, but an integral system that supports and acts together. This enhancement of integrity helps to improve the ability of the slope protection structure to resist external impact forces, making the slope more stable when facing natural disasters (such as earthquakes, landslides, etc.). In addition, the reinforcement wall 2 can disperse and absorb the stress transmitted from the slope surface to avoid local damage caused by stress concentration. It acts like a barrier, evenly dispersing the stress to the adjacent retaining walls 1, thereby reducing the pressure on a single retaining wall 1. This stress dispersion mechanism helps to extend the service life of the slope protection structure and improve the stability of the slope.

[0035] Preferably, Figure 2As shown, the reinforcing wall 2 is arched, the arch top of the arched structure faces the retaining wall 1 located at a high position, and the two arch feet are against the retaining wall 1 located at a low position. The arched structure itself has excellent stability and bearing capacity, and can effectively disperse the soil pressure and water flow impact force from above to the two arch feet, and then transmit it to the adjacent retaining wall 1. The design of the arch top facing the high retaining wall 1 enables the arched structure to better adapt to the inclination angle of the slope, provide a more stable support force, and prevent the retaining wall 1 from tilting or collapsing due to uneven force. In addition, the stress distribution of the arched structure is more uniform, which can effectively reduce the local stress concentration phenomenon and avoid the damage of the reinforcing wall 2 due to excessive stress. The two arch feet are against the low retaining wall 1, forming a stable support point, which further enhances the stability of the entire slope protection structure. In addition, the top of the arched structure faces the high retaining wall 1, which is conducive to the discharge of rainwater and surface water. Rainwater can flow to both sides along the surface of the arch structure, reducing the accumulation of water on the slope and thus reducing the risk of soil erosion.

[0036] In some embodiments, Figure 4 As shown in or 5, the lower reinforcement net 4 protruding above the slope between the two adjacent retaining walls 1 is fixed together with the upper reinforcement net 3 by a plurality of positioning nails 5. First, the positioning nails 5 serve as connecting parts to tightly fix the upper reinforcement net 3 and the lower reinforcement net 4 together, ensuring a firm connection between the two. This connection strength enables the reinforcement net to resist as a whole when facing external impact forces, reducing the risk of local damage caused by loose connection. Secondly, before the plants have grown into shape or fail to provide sufficient support, the positioning nails 5 serve as temporary fixing parts to tightly connect the upper reinforcement net 3 and the lower reinforcement net 4 together, ensuring the stable shaping of the reinforcement net on the slope. This shaping effect prevents the reinforcement net from shifting or deforming due to external factors such as wind and water flow, and maintains the integrity of the slope protection structure.

[0037] In some embodiments, the plant seeds are specifically seeds of herbaceous plants, shrubs or trees that are suitable for local climate and soil conditions. Preferably, the plant seeds have the characteristics of drought resistance, barrenness resistance, well-developed root system and rapid growth. This improves the survival rate of plants, enhances the stability of slopes, promotes ecological restoration, improves the durability of slope protection systems, forms a natural protective barrier and enhances the landscape effect, and also makes the ecological slope protection system more complete, reliable and beautiful, providing effective protection for fractured rock slopes.

[0038] In some embodiments, Figure 4As shown in Figure 5, the upper reinforcement net 3 and the lower reinforcement net 4 are both in a relaxed state. First, the reinforcement net in a relaxed state can better adapt to the slight deformation of the slope caused by natural factors (such as temperature changes, water infiltration, soil settlement, etc.). This adaptability reduces the stress concentration of the reinforcement net caused by the deformation of the slope, and avoids the damage or failure of the reinforcement net. Secondly, when the slope is subjected to external impact forces (such as falling rocks, wind flow, water flow, etc.), the reinforcement net in a relaxed state can absorb part of the energy through deformation, thereby reducing the impact on the slope body. This energy absorption mechanism helps to reduce the risk of slope damage and improve the impact resistance of the slope protection system. In addition, since the reinforcement net is in a relaxed state, it is subjected to less stress, thereby reducing material fatigue and aging caused by long-term stress. This design helps to extend the service life of the reinforcement net and reduce the maintenance cost of the slope protection system. Moreover, the reinforcement net in a relaxed state is easier to adjust its position during installation, adapting to the shape and curvature of the slope, and improving the construction efficiency. At the same time, the reinforcement net in a relaxed state has a better tolerance for errors during the construction process, reducing the difficulty of construction.

[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
