[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] like Figure 1 As shown, a roadbed slope reinforcement device of this application includes a support frame 1, which provides the main mechanical support and ensures the stability and durability of the entire device. The support frame 1 has multiple mounting interfaces 11 for fixing anchor bolts 2, reinforcement panels 3, and other components. The positions of these interfaces are rationally planned to adapt to specific engineering needs. To improve the lateral pressure resistance of the support frame 1 and enhance its resistance to complex stress environments, the support frame 1 is specially equipped with multiple layers of reinforcing ribs 12. By introducing an optimized tilt angle design at key structural parts, not only is the applied force distributed more evenly on both sides of the structure, but it also helps to prevent localized deformation due to pressure. In other words, the support frame 1 of this application has tilted flanges on both sides to increase the contact area with the ground. Furthermore, specially designed locking components are embedded to enhance the safety and reliability of the connections between components.

[0028] The reinforcing ribs 12 built into the roadbed slope reinforcement device of this application can greatly increase the moment of inertia of the section; secondly, the special inclined wing surface treatment reduces the pressure concentration effect at the tip; finally, the embedded locking member 13 ensures that the various components fit together without gaps and can be durable.

[0029] Anchor bolt 2 is connected to support frame 1 and configured to penetrate into different levels within the slope from support frame 1. This type of component is crucial for firmly locking the reinforced body into the undisturbed soil and is typically made of high-strength, corrosion-resistant metal. It must possess good penetration capability and sufficient embedment length; furthermore, it requires excellent adhesion or other mechanisms, such as an expanded end to enlarge the friction interface, ensuring long-term stability without disrupting the surrounding ecological balance. For example, anchor bolt 2 may have threads or a roughened surface to enhance its anchoring efficiency.

[0030] To ensure the reinforcing panel 3 covering the outside of the support frame 1 adheres tightly and does not loosen or detach, a shear key 4 is provided between them. A reliable connection is achieved through an interlocking toothed contact, preventing separation even under significant horizontal tensile stress or bending moment. In one embodiment, this type of device employs an interlocking mechanism, utilizing precisely matched protrusions and recesses to transfer applied loads until they share the external force, keeping the entire plane flat, firm, and stable. This effectively protects the underlying layer from damage and prevents adverse factors from being transmitted and interfering with internal stability.

[0031] This application improves the design of the internal structure. Specifically, the support frame 1, including internal reinforcing ribs 12, inclined flanges, and the application of locking components, all contribute to forming a stable support core. Simultaneously, the external combination of anchor bolts 2 and reinforced panels 3 enhances physical fixation strength and provides a reliable surface sealing effect, preventing soil erosion and further consolidating the overall performance of the roadbed slope. Specifically, the inclined angle design and embedded locking components disperse pressure from the soil sides, reducing potential damage from excessive stress at a single point. The anchor bolts 2 directly root this reinforced structure into the geology, allowing all forces to ultimately return to the soil itself, achieving efficient and stable lateral pressure resistance and ensuring safety during long-term operation.

[0032] In one embodiment, such as Figure 2 As shown, the support frame 1 of the roadbed slope reinforcement device of this application adopts a staggered arrangement of reinforcing ribs 12. This staggered arrangement ensures that the reinforcing ribs 12 can form a complex but regular spatial distribution within the support frame 1, so that the ribs not only intersect each other but are also staggered. This layout enhances the overall frame's ability to resist external lateral pressure by maximizing the use of the material's own physical properties. This design optimizes the force transmission path, avoids stress concentration in a certain area, and further ensures that the entire support system can effectively disperse the externally applied pressure.

[0033] The reinforcing ribs 12 are installed within the internal space of the support frame 1, specifically arranged in a multi-layered, multi-directional intersecting network. Due to the interlacing characteristics of the ribs, both horizontal and vertical loads are more evenly distributed to multiple contact points, greatly improving the overall rigidity of the support frame 1.

[0034] For example, during manufacturing, a combination of stamping and welding processes can be used. Pre-designed reinforcing ribs 12 are embedded within a pre-defined support frame 1. The reinforcing ribs 12 are then pressed under heating to conform to a predetermined shape and complete assembly. This ensures that all ribs are arranged strictly according to a staggered pattern without affecting the functional integrity of other components such as the mounting interface 11 or locking parts. Ultimately, this meticulous structural arrangement gives the roadbed slope reinforcement device superior stability and safety.

[0035] In one embodiment, the support frame 1 of the roadbed slope reinforcement device of this application is equipped with inclined flanges at specific angles, specifically 35° to 45°, on both sides. This design, by reasonably optimizing the angle range, effectively enhances the overall stability of the structure while ensuring convenient construction. The inclined installation method of the support frame 1 allows it to better distribute the force lines when subjected to external loads, thereby achieving the effect of dispersing and alleviating local high stress areas. This structural form is suitable for slope reinforcement needs under different geological conditions and can widely cope with engineering application scenarios in various complex environments.

[0036] In one embodiment, continue to refer to Figure 2 The embedded locking member 13 of the roadbed slope reinforcement device of this application includes a retractable locking pin. The embedded locking member 13 is located inside the support frame 1 and is mainly installed in a specific area between the reinforcing ribs 12. It is fixed in an appropriate position through pre-drilled holes or slots to ensure full contact with the connecting components and effective locking. The embedded locking member 13 consists of multiple sub-components, including an adjustable outer shell and internally integrated mechanical structures such as springs, sliding rods, and trigger components to achieve the retractable function of the locking pin. This device automatically adjusts the locking pin to the optimal working state through a preset force and maintains a stable connection.

[0037] Furthermore, the embedded locking element 13 features a unique design where the locking pin can dynamically adjust its length and the applied locking force according to actual stress conditions. When the locking pin is connected to external components such as the anchor rod 2, it adapts to different load requirements through the cooperation of internal and external structures, and ensures that each closing and opening action is just right by precisely controlling the spring pressure. For example, in the event of extreme geological changes or increased environmental pressure, the elastic element in the system allows the locking pin to retract moderately to prevent overpressure damage, and reapplies the appropriate clamping force under normal conditions, thereby ensuring connection reliability during long-term operation.

[0038] In one embodiment, the locking mechanism relies on a pair of opposing, mirror-configured moving parts to form the locking pin. When the two parts approach each other, they are drawn together by magnets or the attraction between friction surfaces until they are fully engaged; conversely, as they move away, a return spring automatically returns them to their original position, awaiting the next activation. This design ensures precise matching and a secure connection with each engagement. During this process, the locking pin provides feedback on its current position and stress value to the control system via built-in sensors, allowing for further fine-tuning to achieve optimal performance.

[0039] In one embodiment, vertically arranged support rods 17 are added to the support frame 1 of a roadbed slope reinforcement device according to this application. This design provides additional longitudinal stability. The support rods 17 are positioned within the critical load-bearing area inside the support frame 1 to enhance the performance of the entire device under external pressure. Specifically, these support rods 17 are vertically installed at the center and around the perimeter inside the support frame 1, forming a mesh-like distribution structure, thereby effectively preventing deformation or twisting of the support frame 1.

[0040] To further enhance the stability and strength of the structure, the end of the support rod 17 is rigidly connected to the support frame 1 using a special fixing method. This connection ensures that the support rod 17 can not only provide support for the entire system under static conditions, but also remain stable under dynamic changes or external impacts.

[0041] For example, the support rod 17 can be attached to the corresponding position of the support frame 1 using high-strength screws, bolts, or welding to ensure that there is no loosening or displacement between them. In addition, all contact surfaces must be smoothed and coated with an anti-rust layer so that they do not lose their mechanical properties and protective capabilities during long-term use.

[0042] In one embodiment, return to reference Figure 1 In this application, a buffer pad 18 is provided at the installation interface 11 of a roadbed slope reinforcement device. The multiple installation interfaces 11 on the support frame 1 are key components for connecting other parts. Given that these interfaces may be subjected to frequent external forces during long-term use, buffer pads 18 are specifically configured inside them to mitigate mechanical vibrations. This design significantly reduces the risk of structural fatigue caused by the transmission of external forces, improving the durability and safety of the entire system. By introducing this buffer structural element, the device's stability and reliability are ensured while enhancing its adaptability to various uncertainties under environmental changes and working conditions.

[0043] The buffer pad 18 is specifically positioned adjacent to the mounting interface 11. It is typically made of materials with high elastic modulus and weather resistance, such as rubber or special polymer materials. This material selection not only effectively isolates hard impacts in the vibration energy transmission path, but also has certain wear resistance and oxidation resistance properties, ensuring stable performance during long-term use.

[0044] For example, in a practical technical implementation, an appropriate cavity space can be reserved during the manufacturing of the support frame 1 for embedding a pre-formed buffer pad 18, and the size and shape of the pad can be customized according to the actual needs of the mounting interface 11. In this way, when external pressure or vibration is transmitted through the interface, the pad can compress and deform immediately to absorb excess energy, reducing its impact on the interface and related components.

[0045] In one embodiment, continue to refer to Figure 1 The anchor rod 2 of the roadbed slope reinforcement device of this application is provided with a helical blade 21. The helical blade 21 is designed to provide better lateral fixation when embedded in the soil layer. This design increases the friction between the anchor rod 2 and the soil layer, thereby making the entire device more firmly anchored in the roadbed slope. Through this structural reinforcement, the lateral pressure resistance is significantly improved. Specifically, the helical blade 21 is distributed in a helical shape along the surface of the anchor rod 2, forming a thread-like shape, which can cut the soil during the advancement process and further fill the gap between the anchor rod 2 and the soil to ensure a firm bond. After installation, the device can better resist lateral pressure from all directions.

[0046] Specifically, it is necessary to select an anchor rod 2 material and the thickness and spacing of the helical blades 21 that are suitable for the project requirements. For example, materials with high wear resistance and corrosion resistance can be selected to adapt to complex and variable soil environments. In practice, the anchor rod 2 with helical blades 21 is vertically driven into the surrounding rock or soft soil using specialized equipment, ensuring that the helical blades 21 are tightly attached to the soil surface, thereby enabling the device to achieve better embedding performance and stability.

[0047] In one embodiment, an expansion bolt 22 is added to the end of the anchor rod 2 of the roadbed slope reinforcement device of this application to further enhance its bonding strength with the soil. This design is achieved by introducing an expansion bolt 22 with an expansion function at the end of the anchor rod 2. After the anchor rod 2 is installed into the slope, tightening the expansion bolt 22 causes its front end to expand and tightly fit against the surrounding soil particles or rock layer, thereby effectively improving the overall anchoring effect. This connection method ensures that sufficient mechanical performance support can be provided even in relatively soft or irregular strata.

[0048] Specifically, the main body of the expansion bolt 22 is a hollow tubular structure with a series of serrated protrusions on the outside and a conical bolt inside. When the conical bolt is screwed in, its front end pushes the expansion part outward, tightly embedding it into the drilled soil, thus allowing the anchor 2 to be more stably fixed therein. For example, in actual operation, the anchor 2 is first pre-inserted to a preset depth by the drilling rig, and then the expansion bolt 22 is inserted and screwed in until the expansion part is fully expanded, ultimately achieving the reinforcement purpose.

[0049] In this design, the expansion bolt 22 not only increases frictional resistance to improve pull-out resistance but also compensates for minor deviations that may occur during construction. By directly contacting the soil and applying radial pressure, the device's performance in complex environments can be significantly improved. Therefore, this improvement helps ensure the durability and reliability of the entire reinforcement system.

[0050] In one embodiment, such as Figure 3 As shown, the surface of the reinforcing panel 3 of the roadbed slope reinforcement device of this application is treated with a sawtooth texture 31. This design significantly improves the friction of the reinforcing panel 3, thereby enhancing the anti-slip performance of the entire device. The reinforcing panel 3 is located outside the support frame 1, forming a continuous and stable protective surface that covers the entire support structure and is tightly bonded to it. By adding sawtooth texture 31 to the surface, not only can the surface roughness and contact area be effectively increased, but greater frictional resistance can also be generated when there is relative movement with the soil or fill material, improving the overall stability of the system. Especially in cases where the slope is prone to sliding or instability, this improvement helps prevent the reinforcing panel 3 from shifting due to external forces.

[0051] In practice, the reinforced panel 3 can be manufactured using various methods, such as casting, stamping, or engraving. To ensure uniform surface texture and good durability, high-strength wear-resistant materials can be selected. During construction, the integrity and precision of the serrated texture 31 must be ensured. This approach not only improves the visual appearance but also further ensures the structural safety and stability. Furthermore, during installation, the reinforced panel 3 must be tightly fitted to the outside of the support frame 1 and maintain a high degree of integration with the support frame 1 through the internal shear keys 4, allowing the synergistic effect of both to be fully realized.

[0052] In one embodiment, the shear key 4 of the roadbed slope reinforcement device of this application is made of high-strength alloy material, and has several tiny barbs on its contact surface. This design is to ensure that no relative displacement occurs when transmitting force. The shear key 4 is installed between the support frame 1 and the reinforcement panel 3, serving as an important connecting element between the two. By using high-strength alloy material, the overall mechanical properties and durability of the shear key 4 can be improved. The selection of alloy material also needs to consider the specific application environment of the material to ensure that it can resist the effects of external corrosion factors for a long time. In addition, the tiny barbs added to the contact surface of the shear key 4 can significantly increase the friction coefficient of the contact surface, effectively preventing relative sliding between the two parts due to stress.

[0053] Specifically, the barbed structure can be small, tooth-like protrusions arranged in a regular pattern on both sides or surface of the shear key 4. During installation, these protrusions penetrate into the microstructure of the surfaces of the reinforcing panel 3 and the supporting frame 1 at their joints, creating a mechanical locking effect. This not only helps to transfer the force load acting on them but also further reduces any potential risk of interface separation. For example, during installation, the barbed shear key 4 is first placed in position, and then sufficient clamping force is applied sequentially to ensure that the barbs are firmly embedded in the corresponding components, guaranteeing stability and a reliable mechanical connection. Through this structure and method, the effective operation of the entire reinforcement device is ensured, improving the stability and reliability of the overall roadbed slope reinforcement.

[0054] In one embodiment, an anti-corrosion and corrosion-resistant coating 42 is added between the reinforcement panel 3 and the support frame 1 of the roadbed slope reinforcement device of this application. This layer, installed between the two, effectively prevents moisture, corrosive gases, and particulate matter from the external environment from penetrating the internal structure. The addition of this coating ensures that the internal mechanical components of the reinforcement device maintain stable performance and sufficient durability throughout its service life, even when exposed to harsh environments for extended periods. This design allows the device to not only stabilize the slope during the initial construction phase but also reduce unnecessary wear and repair work during later maintenance.

[0055] Specifically, the anti-corrosion coating 42 is a protective film composed of high-performance materials, typically high-molecular composite materials with excellent chemical resistance and water resistance. To ensure complete coverage and tight adhesion, it is usually prepared by spraying or impregnation methods, with strict control of temperature and humidity parameters during manufacturing to ensure optimal physical properties.

[0056] For example, this anti-corrosion coating 42 can be evenly applied to the outer surface of the installed support frame 1 using a spraying device before the reinforcement panel 3 is installed. In practical applications, different thickness grades and formulation ratios of coating materials can be selected according to the specific conditions of the construction environment to achieve the optimal protective effect. In addition, for specific geological conditions, appropriate additives can be added to improve the coating's adaptability.

[0057] In this design, the coating adheres directly to the surface of the support frame 1, forming a seamless cover, while being pressed firmly onto the back of the untreated reinforcement panel 3 before installation. This arrangement ensures that the coating acts as a barrier between the two critical structural components. The reinforcement panel 3 continues to perform its intended function—fitting snugly against the support frame 1 to resist external impacts, while this intermediate protective structure further enhances the overall structural stability and lifespan.

[0058] In one embodiment, the components of the roadbed slope reinforcement device of this application are connected by threads, and anaerobic sealant is applied to the connection points to ensure a sealing effect. This design effectively prevents moisture from entering the device through the thread gaps, avoiding corrosion of metal parts due to moisture, thereby extending the service life of the overall structure. The support frame 1 is provided with multiple mounting interfaces 11 for fixing other components, while the anchor rods 2 are connected to the support frame 1 and penetrate into the soil, ensuring that the entire device can be stably anchored inside the roadbed slope. The reinforcement panel 3 is located on the outside of the support frame 1, forming a continuous protective plane. Furthermore, the connection points between the components all use high-quality standard threaded connections, ensuring mechanical performance while simplifying installation and maintenance procedures.

[0059] For example, in practical implementation, after ensuring all components are accurately assembled in their preset positions, threaded connectors of appropriate specifications are used to securely connect each component, including the support frame 1, anchor rods 2, reinforcing panel 3, and the intermediate shear key 4. Throughout the connection process, strictly following process requirements, a certain amount of high-efficiency anaerobic sealant is evenly applied to the corresponding thread surface before each tightening of the nut to achieve a waterproof seal. This not only improves the reliability of the device but also provides necessary protection for long-term exposure to outdoor environments. This approach is applicable to all critical connection points to ensure the overall device has good moisture and corrosion resistance.

[0060] In practical operation, when using this device, the support frame 1 is first placed at the location on the roadbed slope requiring reinforcement. Then, multiple anchor bolts 2 are connected to the support frame 1 and driven deep into the soil to ensure the entire device is firmly anchored within the roadbed slope. Next, a reinforcement panel 3 is installed over the support frame 1, forming a continuous plane that fits tightly against the support frame 1, thus protecting the support structure and resisting external forces. Shear keys 4 are installed between the support frame 1 and the reinforcement panel 3, using a meshing structure to effectively transfer shear force, promoting a tight connection and coordinated operation between the two, ensuring the stability of the overall structure. Furthermore, by optimizing the tilt angles on both sides of the support frame 1, stress distribution can be dispersed, further improving the overall load-bearing capacity and durability of the device. Simultaneously, the embedded locking element 13 ensures a secure connection between all structural components, thereby enhancing the overall reinforcement effect. The entire process is carried out systematically, ensuring that this roadbed slope reinforcement device effectively improves the stability and safety of the roadbed slope.

[0061] The exemplary systems and methods of the present invention have been specifically shown and described with reference to the above embodiments, which are merely examples of the best mode for implementing the systems and methods. Those skilled in the art will understand that various changes can be made to the embodiments of the systems and methods described herein without departing from the spirit and scope of the invention as defined in the appended claims when implementing the systems and / or methods.
