Description

Technical Field

[0001] This invention relates to the field of ecological protection technology, and in particular to a V-shaped slope ecological protection structure. Background Technology

[0002] Slope ecological protection mainly involves using plants or a combination of plants and engineering materials to reinforce, protect, and restore various slopes. Some slopes are prone to soil erosion, landslides, and collapses, threatening the surrounding ecological environment. Currently, slope protection is mainly divided into engineering protection and ecological protection. Traditional engineering protection primarily uses masonry slope protection, concrete slope protection, and the addition of anchor structures for reinforcement. While these methods offer strong erosion resistance and structural strength, they close off the slope surface and hinder plant growth, resulting in an unsatisfactory ecological environment. Therefore, with increasing awareness of ecological protection, ecological protection technologies are now being applied more extensively.

[0003] However, existing ecological protection structures have several unresolved problems: First, slope surfaces are often uneven, with local rock protrusions or depressions. Traditional protection structures are mostly fixed-size flat plate structures or mesh mats, which cannot fit the uneven slope surface, thus weakening the support and protection capacity of the slope and making it prone to seepage and causing local collapses. Second, existing protection structures use a large number of anchors (such as expansion bolts, anchor rods, etc.) for fixing on the slope surface, which is cumbersome and complex to install. Additional connecting parts such as hanging rings and ear plates are required, and the protection components are laid independently with poor interconnectivity. Finally, they cannot be adapted to different slope shapes, and on-site installation is not flexible enough and inefficient.

[0004] Therefore, based on customer feedback regarding the shortcomings of the existing device, the inventors made further improvements to overcome the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a V-shaped slope ecological protection structure that can adapt to uneven slopes, is easy to install, has strong overall structural stability, is flexible to assemble, and is suitable for various slope conditions.

[0006] The objective of this invention is achieved through the following technical solution: a V-shaped slope ecological protection structure, comprising: A bottom mesh structure is provided and fitted onto the surface of the slope, and the bottom mesh structure adapts to the unevenness of the slope surface. A plastic skeleton structure, wherein the plastic skeleton structure is made of plastic with a certain rigidity and strength, and the bottom of the plastic skeleton structure is connected to the bottom mesh structure to form a rigid spatial unit I that can hold soil.

[0007] As a preferred technical solution of this application, the plastic skeleton structure has a limiting structure; the limiting structure includes an upper limiting structure and a lower limiting structure, with the upper limiting structure opening downwards and the lower limiting structure opening upwards; when multiple rigid area spaces I are laid on the slope, the connecting wires / twisted rope mesh are pushed into the upper limiting structure through the lower opening and into the lower limiting structure through the upper opening -- forming a structure for rapid installation and laying.

[0008] As a preferred technical solution of this application, the plastic skeleton structure includes a first side plate and a second side plate, and the first side plate and the second side plate are connected to form a V-shaped skeleton structure; and from the side view, the extension direction of the ridge line of the V-shaped structure forms an acute angle with the opening direction of the V-shaped structure.

[0009] As a preferred technical solution of this application, both the first side plate and the second side plate are wavy curved surfaces, and the undulating structure of the wavy curved surface itself forms a reinforcing rib; the convex surface of the wavy curved surface forms a corresponding upper limit structure and a lower limit structure through slots.

[0010] As a preferred technical solution of this application, the fixed end of the bottom mesh structure is connected to the bottom of the first side plate and the second side plate respectively, thereby forming a rigid region unit I with an acute triangular shape.

[0011] As a preferred technical solution of this application, the bottom mesh structure includes two layers of flexible mesh, both layers of mesh having a fixed end and a free end, and the fixed edge of each mesh is used to connect with the V-shaped frame, while the free end fits against the uneven slope surface.

[0012] As a preferred technical solution of this application, the connection between the first side plate and the second side plate is formed by opening a notch to create an installation opening, thereby creating clearance space for connecting wires / twisted rope mesh to pass through.

[0013] As a preferred technical solution of this application, the two layers of mesh in the bottom mesh structure are overlapped and staggered, and multiple mesh holes are opened on each mesh, which are set as circular mesh holes or rectangular mesh holes.

[0014] A slope ecological protection system, comprising: A twisted rope grid, wherein the twisted rope grid is formed by interlacing multiple twisted ropes with a certain rigidity to form a grid-like structure; First, the twisted rope grid is laid on the slope surface. Then, multiple V-shaped slope ecological protection structures as described in any one of the claims are connected to the connecting wires in the twisted rope grid through their respective limiting structures, so that multiple V-shaped slope ecological protection structures are arranged along the slope surface. Among them, multiple V-shaped slope ecological protection structures are spliced ​​and combined in the twisted rope grid to form one or more combinations of a rhomboid grid structure or a W-shaped continuous structure according to the slope geological conditions.

[0015] As a preferred technical solution of this application, the adjacent V-shaped slope ecological protection structures are connected to each other in the rope grid by connecting wires being pulled into the limiting structure, so that multiple V-shaped slope ecological protection structures and rope grid form an overall protection system and achieve stable installation.

[0016] The present invention has the following advantages: (1) In this scheme, a double-layer overlapping bottom net structure is set up, and each of the two bottom nets is connected to the bottom edge of the skeleton at only one end, while the other end is freely overlapping, which can naturally fit the uneven rock slope surface; at the same time, this scheme also adopts a limiting structure to avoid the problem of traditional protection structures relying on anchor rods, hanging rings and other decentralized connecting parts, which are cumbersome to install; by prefabricating a multi-directional limiting structure at the crest of the wave-shaped side plate, the plug-and-play installation of the rope grid is realized, which is more convenient and simple. (2) In this solution, a semi-circular notch is assembled into an installation port at the V-shaped skeleton ridge line, which can also properly place the corner of the connecting wire and serve as a positioning rod for insertion. Its design simplifies the on-site operation process and effectively improves structural safety and work efficiency. (3) In this scheme, the side plate adopts a wave-shaped curved surface instead of a flat plate shape, which improves the rigidity of the mechanism and is also suitable for setting a limit structure. In addition, according to actual needs, the skeleton structure in this scheme can be manufactured and processed using different polymer plastic materials, which improves the rigidity and stability of the structure, and is low in cost and easy to manufacture.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0019] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use, or the orientation or positional relationship in which those skilled in the art would conventionally understand it. Such terms are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0021] (Example 1) Therefore, based on the above issues, please refer to Figure 1 This invention proposes a V-shaped slope ecological protection structure to solve the problem.

[0022] See Figures 1-4 The proposed implementation plan includes a V-shaped slope ecological protection structure, a plastic frame structure, a bottom mesh structure 3, and a limiting structure. Among them, see Figure 1 and Figure 2 The plastic skeleton structure is V-shaped, and the V-shaped skeleton includes a first side plate 1 and a second side plate 2. The side edges of the first side plate 1 and the second side plate 2 are connected together, and its bottom is connected to the bottom net structure. Thus, they are set together on the slope and form an acute-angled triangular soil-holding area with the slope surface. This not only avoids rainwater from directly eroding the slope surface, but also retains some water in the rigid area space unit I for plant growth. Among them, see Figures 1-2 The bottom mesh structure 3 is installed on the bottom surface of the V-shaped frame. The bottom mesh structure 3 consists of two overlapping mesh layers, namely the upper mesh 4 and the lower mesh 5. One side of the upper mesh 4 is connected to the bottom edge of the first side plate 1, while one side of the lower mesh 5 is connected to the bottom edge of the second side plate 2. The other side of each mesh layer is a free end, which fits into the uneven slope surface. Among them, see Figure 1 and Figure 3 The limiting structure is set on the V-shaped frame and on the side plate surface of the first side plate 1 and the second side plate 2, for connection and fixation with the external connecting wire 11; wherein, the connecting wire 11 is installed in the opening of the limiting structure.

[0023] It should be noted that the connecting wire 11 is made of steel wire rope, so that multiple steel wire ropes are intertwined and form a twisted rope grid 12.

[0024] Currently, existing slope ecological protection structures cannot effectively fit uneven slopes, resulting in poor adaptability. Furthermore, these structures require numerous anchors for fixation, making installation cumbersome. This solution proposes a V-shaped slope ecological protection structure. By assembling a V-shaped frame and cooperating with the bottom net and limiting structure, it can be quickly installed and engaged with the twisted rope grid 12. The structure is simple and easy to install. The double-layered, non-fully fixed bottom net structure 3 can adapt to uneven slope surfaces, improving installation and usage efficiency.

[0025] In this embodiment, see Figure 1 For the V-shaped frame, the V-shaped frame is mainly composed of a first side plate 1 and a second side plate 2. The first side plate 1 and the second side plate 2 are integrally molded structures. The side plates are made of polypropylene (PP) material by injection molding, which has a certain strength. From the side view, the extension direction of the ridge line of the V-shaped structure forms an acute angle with the opening direction of the V-shaped structure. At the same time, the first side plate 1 and the second side plate 2 are both wavy curved surfaces 13. The crests and troughs of the wavy curved surfaces 13 are arranged alternately, and their length direction is parallel to the line direction. By setting the side plates to be curved, the bending stiffness of the side plates can be improved, making them less prone to deformation when subjected to pressure.

[0026] Furthermore, in this solution, the limiting structure is set on the outer surface of the first side plate 1 and the second side plate 2. The limiting structure includes an upper limiting structure 6 and a lower limiting structure 8, wherein the upper limiting structure 6 has an opening facing downward and the lower limiting structure 8 has an opening facing upward, so that the connecting wire 11 is pushed into the upper limiting structure 6 from the lower opening 7 of the upper limiting structure 6, and pushed into the lower limiting structure 8 through the upper opening 9 of the lower limiting structure 8.

[0027] Furthermore, a gap 10 is provided between the two upper limit structures 6 and the two lower limit structures 8 arranged in parallel. The gap 10 does not have a limiting protrusion to facilitate the installation of the connecting wire 11. Each opening has a certain gap width, which is slightly larger than the diameter of the connecting wire 11 to be matched, so that the connecting wire 11 can be smoothly inserted. At the same time, the gap also has a certain gap height, so that the twisted rope grid 12 can move up and down, be flexibly installed, and be easy to use.

[0028] It should be noted that the slots in the limiting structure are all opened on the protruding surface (i.e., the crest position) of the wavy curved surface 13, using the undulating structure of the curved surface itself as the opening surface of the limiting structure, without the need to set up additional bosses; thus, this design makes the limiting structure and the wavy curved surface 13 an integrated structure, which simplifies the structure and ensures the strength of the limiting structure.

[0029] In this embodiment, see Figures 1-3 For the bottom mesh structure 3, the bottom mesh structure 3 is composed of two overlapping mesh layers (the upper mesh layer 4 and the lower mesh layer 5, respectively). In this scheme, both mesh layers are made of polypropylene (PP) material, and the mesh holes on the mesh are circular mesh holes 15. One side of the first mesh layer is connected to the bottom edge of the first side plate 1, and one side of the second mesh layer is connected to the bottom edge of the second side plate 2. The connection method is to embed the mesh into the edge of the side plate to achieve an integrated connection.

[0030] During installation, first, lay the external twisted rope grid 12 on the cleaned slope surface, then place the V-shaped frame on the slope surface with its bottom facing the slope surface and the ridge line forming an acute angle with the slope surface; align the rope segments in the twisted rope grid 12 with the limiting structures, and respectively insert them into the upper limiting structure 6 with the lower opening 7 and the lower limiting structure 8 with the upper opening 9; the upper and lower limiting structures respectively restrict the connecting wires 11 from detaching upwards and downwards, thereby forming a reliable engagement.

[0031] It should be noted that after the V-shaped frame is completed, planting substrate can be filled into the space between the frame and the slope. Finally, grass seeds or shrub seedlings are sown on the substrate surface and then routine maintenance is carried out.

[0032] Meanwhile, this solution uses a V-shaped skeleton and bottom mesh structure made of PP material, which has the following advantages: low density, resulting in light weight of individual pieces, making it easy to transport and handle on site; good chemical corrosion resistance, resisting acid and alkali substances in the soil; good fatigue resistance, not prone to fatigue failure; and low cost, making it suitable for large-scale promotion and application.

[0033] (Example 2) This embodiment is basically the same as embodiment 1, except that the bottom mesh structure 3 in this embodiment is made of polyethylene (PE) material.

[0034] In this embodiment, see Figure 4 The two layers of mesh in the bottom mesh structure 3 are made of PE material. The mesh is also evenly opened with multiple rectangular mesh holes 16. The PE material has excellent flexibility and low temperature toughness. Even in a low temperature environment of -30℃, it can still maintain good flexibility and will not crack. Therefore, it is suitable for use and construction in cold regions during winter.

[0035] (Example 3) This embodiment is basically the same as Embodiment 1, except that the V-shaped skeleton is made of polyethylene terephthalate (PET) material.

[0036] Specifically, the V-shaped frame is made of PET material. Due to the high strength of PET material, this embodiment can reduce the thickness of the side plate while still maintaining sufficient structural rigidity, thereby further reducing the structural weight. At the same time, PET material has good heat resistance and can be used for a long time in high-temperature environments, making it suitable for hot climates.

[0037] The limiting structure, which needs to withstand the tension and friction of the connecting wire 11, uses the same PET material as the skeleton. Its high strength and high wear resistance ensure that the limiting structure will not wear out or fail during long-term use. In addition, the bottom mesh structure 3 can still use PP or PE material to maintain flexibility.

[0038] (Example 4) This embodiment is basically the same as Embodiment 1, except that the V-shaped skeleton is made of polycarbonate (PC) material.

[0039] Specifically, the V-shaped skeleton is made of PC material, which has extremely high impact strength, dozens of times that of ordinary plastics, and maintains good toughness even in low-temperature environments.

[0040] This embodiment uses PC material, which is suitable for slope protection projects with the risk of rockfall. When a rockfall hits the V-shaped frame, the high toughness of the PC material can absorb the impact energy, prevent structural breakage, and ensure the integrity of the protection system. Even if large deformation occurs, the PC material is not easy to break and can continue to play a protective role.

[0041] (Example 5) This embodiment is an improvement on embodiment 1. The two layers of mesh in the bottom mesh structure 3 are arranged in a staggered manner, and the mesh holes on them are of different diameters.

[0042] Specifically, see Figure 3 The bottom mesh structure 3 includes an upper mesh 4 and a lower mesh 5, which are staggered in a direction perpendicular to the ridge line. The upper mesh 4 is connected to the bottom edge of the first side plate 1, and the lower mesh 5 is connected to the bottom edge of the second side plate 2. The staggered arrangement makes the free ends of the two meshes different in length, so that the free end of the upper mesh 4 is longer and the free end of the lower mesh 5 is shorter.

[0043] Furthermore, when installed on uneven slopes, the two layers of mesh form a stepped coverage; in the depressions of the slope, the mesh, due to its longer free end, can hang down to the bottom of the depression to achieve a close fit; in the convex areas of the slope, the lower mesh 5, due to its shorter free end, may be pushed up, but the upper mesh 4 can still remain in contact; thus achieving full coverage of the uneven deformation of the slope.

[0044] Furthermore, in this embodiment, the mesh apertures 15 of the two mesh layers are set differently: the mesh aperture D1 of the upper mesh 4 is larger; the mesh aperture D2 of the lower mesh 5 is smaller, thus creating a difference in aperture.

[0045] Therefore, when rainwater washes over the slope, large particles (such as gravel) can pass through the large holes of the upper mesh 4 smoothly, but are intercepted by the small holes of the lower mesh 5; while medium-sized particles are blocked by the wires of the upper mesh 4 and remain between the two meshes, effectively reducing soil erosion.

[0046] (Example 6) This embodiment is an improvement on embodiment 1. A semi-circular notch is added to the connecting edge of the first side plate 1 and the second side plate 2, and the two notches form an installation port 14.

[0047] The connecting edges of the first side plate 1 and the second side plate 2 are symmetrically notched with semi-circular notches; when the two semi-circular notches of the first side plate 1 and the second side plate 2 are opposite each other at the ridge line, a nearly circular mounting opening 14 is formed.

[0048] When the rope mesh 12 is laid in the limiting structure, the connecting wire 11 often needs to be bent at the turning point. Placing the corner of the connecting wire 11 at the installation port 14 can avoid the problem of the corner of the connecting wire 11 not being able to be properly placed, and there is no need to open a separate placement gap. Secondly, when a positioning rod can be inserted at the installation port 14, the positioning rod passes through the installation port 14 and extends into the drilled hole on the slope surface to further reinforce the skeleton structure. The positioning rod can be made of steel bars or glass fiber reinforced plastic (FRP) rods.

[0049] It should be noted that the design of mounting port 14 makes full use of the existing structure at the side panel splice, without the need for additional components.

[0050] (Example 7) This embodiment is basically the same as embodiment 1, except that the V-shaped frame adopts a split structure, and the first side plate 1 and the second side plate 2 are assembled at the ridge line through a detachable connection structure; and multiple V-shaped frames are spliced ​​together on the slope to form a diamond grid structure.

[0051] It should be noted that the first side plate 1 and the second side plate 2 are formed independently, and the two are provided with a mortise and tenon connection structure at the ridge line: the connecting edge of the first side plate 1 is provided with a protruding tenon, and the connecting edge of the second side plate 2 is provided with a corresponding mortise. During installation, the protruding tenon is inserted into the mortise to achieve a detachable connection. The split design facilitates transportation and storage, and is especially suitable for mountain construction sites with inconvenient transportation.

[0052] Preferably, multiple V-shaped frames are arranged on the slope in a diamond grid pattern: each V-shaped frame serves as one side of a diamond, thus forming a continuous diamond grid. This arrangement gives the structure good stress performance when subjected to the sliding force of the slope and is suitable for soil or rock slopes with moderate slope.

[0053] (Example 8) This embodiment is basically the same as embodiment 1, except that multiple V-shaped frames are spliced ​​together on the slope to form a continuous W-shaped structure.

[0054] See Figure 6 Multiple V-shaped skeletons are arranged continuously along the longitudinal direction of the slope to form a W-shaped broken line structure; specifically, the ridge direction of adjacent V-shaped skeletons changes alternately; this arrangement can effectively slow down the flow velocity and increase infiltration, and is particularly suitable for steep slopes that require enhanced soil and water conservation.

[0055] (Example 9) Based on Example 1, this embodiment adapts and adjusts the opening shape and size of the limiting structure to accommodate different specifications of connecting wires 11.

[0056] The opening shape of the limiting structure can be adjusted according to the cross-sectional shape of the connecting wire 11: when a circular cross-section connecting wire 11 is used, the opening is set to a U-shape or semi-circle, while when a stranded connecting wire 11 is used, the opening is set to a wavy shape that matches the stranded shape; the opening width is determined according to the diameter of the connecting wire 11, and generally the opening width is larger than the diameter of the connecting wire 11, which ensures that the connecting wire 11 can be inserted smoothly, while avoiding excessive gaps that may cause loosening.

[0057] Firstly, existing slope protection structures cannot effectively conform to uneven slope surfaces (where the rock mass has local protrusions or depressions). Furthermore, existing structures are cumbersome to install and have numerous connectors, making on-site installation inconvenient and reducing work efficiency. Therefore, this solution employs a double-layered, overlapping mesh as the bottom mesh structure 3. Each layer of mesh is connected to the side plate only on one side, with the other side being a free end. This design allows the mesh to adaptively conform to the local unevenness of the slope surface, avoiding gaps between the traditional rigid bottom plate and the slope surface, and effectively preventing runoff infiltration. To address the cumbersome installation issue, this solution uses a V-shaped frame with limiting structures. These limiting structures are integrated into the protruding surface of the wavy side plate, using an upper limiting structure 6 and a lower limiting structure 8. This design achieves rapid engagement and multi-directional positioning of the twisted rope mesh 12 without the need for additional connecting parts such as hanging rings or ear plates. Simultaneously, the symmetrical semi-circular notches on the side panel splicing edges form a near-circular mounting opening 14 at the ridge line, accommodating the corners of the connecting wires 11 and allowing for the insertion of positioning rods for further reinforcement—a single opening serving multiple purposes. Furthermore, the wavy shape of the side panels enhances rigidity and provides openings for the positioning structure. Finally, this design utilizes high-molecular materials such as PP, PE, PET, ABS, and PC, which offer advantages over structural materials, including lower density (reducing structural weight and facilitating transportation and installation) and corrosion resistance (requiring less frequent maintenance). Different materials can be selected based on the functional requirements of different parts (e.g., high-strength PET for the skeleton and flexible PE for the bottom mesh), improving structural performance.

[0058] Finally, it should be noted that the above descriptions 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.
