Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, and in particular to a slope vegetation protective netting. Background Technology

[0002] In the field of slope ecological protection technology, firstly, although traditional rigid vegetation slope protection structures (such as concrete retaining walls) can provide initial stability, their poor ecological integration with vegetation and susceptibility to rainwater erosion leading to structural damage have long existed. While existing flexible vegetation protection nets improve slope protection capacity through a three-dimensional mesh structure, they are susceptible to damage when subjected to strong winds or falling rocks. This is because the protection nets lack flexible buffering solutions with anchoring devices. Consequently, on the one hand, the connection between the protection nets and anchoring devices is prone to breakage due to stress concentration; on the other hand, direct impact from external forces may cause the protection net body to tear. At the same time, the positioning devices (also known as anchoring devices) of the protection nets are prone to loosening under heavy rain. Based on the above, the current rigid slope protection structures and flexible protection nets have poor protective effects.

[0003] Secondly, in both rigid and flexible vegetation slope protection structures, the metal connectors are prone to electrochemical corrosion due to long-term exposure to rainwater. Furthermore, the lack of buffer mechanisms in rigid / flexible vegetation protection structures further exacerbates the fatigue fracture of the connectors under repeated impacts, ultimately leading to their failure. If an external force is directly applied to the metal connectors (such as when a rock falls on them), the connectors are also prone to breakage and failure. Therefore, the protective effect of these two types of structures cannot be guaranteed.

[0004] To overcome the above-mentioned shortcomings, the inventor invented a slope vegetation protection net. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a slope vegetation protection net that achieves good ecological integration with vegetation, is not easily eroded by rainwater, and incorporates a flexible buffer scheme between the protection net and the anchoring device. In the event of strong winds or falling rocks, i.e., when external forces act on the protection net, stress concentration rarely occurs at the connection between the net and the ground anchoring device. The positioning device (also known as the anchoring device) of the protection net is not easily loosened under heavy rain. The metal connectors are not exposed to the rainwater environment, and therefore, the metal connectors are less prone to electrochemical corrosion. Because this application adds a flexible buffer mechanism, after repeated impacts on the protection net, the buffer mechanism bears most of the impact, thus the metal connectors are less prone to fatigue damage. External forces are difficult to directly act on the metal connectors, so the metal connectors are less likely to break or fail, ensuring the protective effect.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A slope vegetation protection net includes a protective net connected to a first right-angled iron plate. The first right-angled iron plate is connected to the top of a spring, and the bottom of the spring is connected to a second right-angled iron plate. The second right-angled iron plate is connected to an adjacent protective net. The two right-angled iron plates and the spring are respectively sleeved on positioning piles. Baffles are respectively set at the top and middle of the positioning piles. The spring and the right-angled iron plate are accommodated between the two baffles. A positioning cylinder is embedded at the bottom of the positioning pile.

[0008] As a further implementation, connecting holes are provided at both ends of the first and second right-angled iron sheets.

[0009] As a further implementation, the upper end of the positioning cylinder is a hollow cylinder, the outer diameter of the positioning stake is the same as the inner diameter of the upper end of the positioning cylinder, and the bottom of the positioning cylinder is conical.

[0010] As a further implementation, a protective cover is detachably connected to the top of the positioning pile.

[0011] As a further implementation, movable through holes are provided on both sides of the protective cover surface, and the cross-section of the movable through holes is rectangular.

[0012] As a further implementation, the height of the movable through hole is greater than the distance between the two baffles, and the width of the movable through hole is greater than the distance between the two ends of the right-angled iron sheet.

[0013] As a further implementation, the bottom of the positioning cylinder is provided with positioning holes at equal intervals, and the positioning plates can be embedded in and penetrate the positioning holes.

[0014] As a further implementation, positioning pieces are evenly spaced on the outer surface of the inner cylinder, and the positioning pieces can slide in along the upper port of the positioning cylinder.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model connects a protective net to a first right-angled iron plate, which in turn connects to the top of a spring. The bottom of the spring connects to a second right-angled iron plate, which in turn connects to an adjacent protective net. The two right-angled iron plates and the spring are respectively fitted onto positioning posts. Baffles are installed at the top and middle of the positioning posts, adding a flexible buffer scheme between the protective net and the anchoring device. In windy weather or when rocks fall, i.e., when external forces act on the protective net, the first and second right-angled iron plates transfer the dynamic load (such as water impact, falling rocks, or strong winds) on the protective net to the spring, preventing stress concentration that could lead to tearing of the protective net. This design achieves force relief, i.e., unloading the external forces acting on the protective net. Stress concentration rarely occurs at the connection between the net and the ground anchoring device because this application adds a flexible buffer mechanism. Therefore, after repeated impacts on the protective net, the buffer mechanism bears most of the impact, making the metal connectors less prone to fatigue damage. Attached Figure Description

[0024] Example 1

[0025] This embodiment provides a slope vegetation protection net, such as Figure 1-4As shown, it includes a protective net 1, which serves as the main protective structure. The protective net 1 fixes the soil and promotes the growth of vegetation roots through its three-dimensional mesh shape, forming a composite protective layer of vegetation and protective net 1. Ultimately, it achieves erosion resistance, soil stabilization, and ecological restoration. The protective net 1 is connected to the first right-angled iron plate 2, which is connected to the top of the spring 3. The bottom of the spring 3 is connected to the second right-angled iron plate 4. The spring 3 expands and contracts within the space defined by the baffle 6, absorbing the deformation energy of the slope when subjected to external forces (such as strong winds, rainstorms, and vegetation growth), and reducing the risk of fatigue damage at the nodes of the protective net 1.

[0026] The first and second right-angled iron plates have connecting holes 8 at both ends. The first and second right-angled iron plates 2 and 4 serve as transitional components between the protective netting 1 and the flexible buffer mechanism. These two right-angled iron plates are designed in a right-angle shape to match the corners of the protective netting 1, facilitating their connection. The connecting holes 8 at both ends enable a mechanical connection between the protective netting 1 and the spring 3. The second right-angled iron plate 4 connects to the adjacent protective netting 1. The first and second right-angled iron plates 2 and 4 transfer the dynamic loads (such as water flow impact, falling stones, and strong winds) on the protective netting 1 to the spring 3, preventing stress concentration that could lead to tearing of the protective netting 1. This design achieves stress relief and prevents fatigue failure of the fixed connection points between the protective netting 1 and the ground due to continuous external force.

[0027] Two right-angled iron pieces (first right-angled iron piece 2 and second right-angled iron piece 4) and a spring 3 are respectively fitted onto the positioning pile 5. Baffles 6 are respectively installed at the top and middle of the positioning pile 5, with the spring 3 and the right-angled iron pieces (first right-angled iron piece 2 and second right-angled iron piece 4) accommodated between the two baffles 6. This design restricts the vertical displacement of the spring 3 and the right-angled iron pieces, preventing structural failure due to excessive compression or tension of the spring 3. A positioning cylinder 7 is embedded at the bottom of the positioning pile 5. The bottom of the positioning cylinder 7 is conical, which enhances vertical penetration into the ground, facilitating penetration of hard rock layers or loose soil layers, resisting rainwater erosion, and withstanding strong winds. The upper end of the positioning cylinder 7 is a hollow cylinder, with the outer diameter of the positioning pile 5 being the same as the inner diameter of the upper end of the positioning cylinder 7. The hollow cylindrical upper end of the positioning cylinder 7 matches the outer diameter of the positioning pile 5, ensuring guiding accuracy during vertical embedding.

[0028] The bottom of the positioning cylinder 7 is provided with positioning holes 11 at equal intervals around the circumference. The positioning holes 11 can be embedded and penetrated by the positioning pieces 12. Then the positioning pieces 12 enter the surrounding soil layer. This method of placing the positioning holes 11 first and then penetrating the surrounding soil layer causes less damage to the firmness of the soil layer around the positioning cylinder 7. Therefore, it has a better vertical grip on the ground. The positioning pieces 12 embedded in the inner cylinder 13 form multi-point anchoring, which increases the firmness of the contact between the positioning cylinder 7 and the ground and enhances the lateral anti-slip ability of the positioning cylinder 7 and the foundation. Each positioning piece 12 forms a lateral support point after penetrating the soil layer.

[0029] The existing positioning cylinder (Chinese patent document CN202020614664.8 "A new type of ecological vegetation blanket slope protection net") uses barbs 601 on the outer surface to increase the bottom firmness. The barbs 601 require a relatively large diameter pit to be dug during installation. The barbs 601 penetrate the soil from top to bottom and will damage the firmness of the surrounding soil. This application first installs the positioning cylinder 7, resulting in a smaller pit diameter (the pit diameter only needs to be the same as the outer diameter of the positioning cylinder 7). After the positioning cylinder 7 is installed, the positioning pieces 12 are evenly spaced on the outer surface of the inner cylinder 13. The positioning pieces 12 can slide in along the upper port of the positioning cylinder 7. The installation of the positioning pieces 12 is an installation scheme from the inside to the outside of the positioning cylinder 7. After the inner cylinder 13 is embedded into the positioning cylinder 7, the positioning stake 5 is then embedded into the positioning cylinder 7. The bottom of the positioning stake 5 contacts the upper surface of the inner cylinder 13. Finally, bolts are passed through the threaded holes on the positioning cylinder 7 and the positioning stake 5 respectively to fix the inner cylinder 13 inside the positioning cylinder 7. The circumferentially distributed positioning holes 11 form multi-point anchoring by embedding the positioning pieces 12, which enhances the lateral anti-slip ability of the positioning cylinder 7 and the foundation. Therefore, this application causes less damage to the firmness of the surrounding soil, and the bonding strength between the scheme of this application and the soil is higher (that is, the grip of the positioning cylinder 7 is relatively stronger). The positioning device of the protective net 1 is not easy to loosen under the erosion of heavy rain.

[0030] Example 2

[0031] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that a protective cover 9 is detachably connected to the top of the positioning pile 5. The detachable protective cover 9 covers the top of the positioning pile 5 to prevent rainwater from directly acting on the connection nodes on the positioning pile 5, thus avoiding metal corrosion. At the same time, it blocks gravel from directly impacting the first right-angle iron plate 2, the second right-angle iron plate 4, and the spring 3. Under the action of external force, the integrity of the connecting components of this application is guaranteed.

[0032] In existing technologies, the connection between the positioning stake 5 and the protective net 1 generally lacks a dedicated protective device. However, the protective cover 9 of this application provides protection against external forces and rainwater erosion. External forces are unlikely to directly act on the metal connectors, and the metal connectors are not exposed to rainwater, thus reducing the risk of electrochemical corrosion. The metal connectors in this application specifically refer to: the first right-angled iron plate 2, the second right-angled iron plate 4, and the spring 3.

[0033] Movable through holes 10 are provided on both sides of the surface of the protective cover 9. The cross-section of the movable through holes 10 is rectangular. The height of the movable through holes 10 is greater than the distance between the two baffles 6, and the width of the movable through holes 10 is greater than the distance between the two ends of the right-angled iron pieces (specifically: the first right-angled iron piece 2 and the second right-angled iron piece 4). The rectangular movable through holes 10 are designed to allow the spring 3, the first right-angled iron piece 2, and the second right-angled iron piece 4 to freely extend and retract within the limiting range of the two baffles 6. The height and width of the movable through holes 10 are greater than the distance between the baffles 6 and the distance between the ends of the two right-angled iron pieces (the first right-angled iron piece 2 and the second right-angled iron piece 4), ensuring that when an external force impacts this application, the metal connecting parts between this application and the protective net 1 are exposed to the external force, that is, it can prevent falling rocks from hitting the metal connecting parts. At the same time, even under the action of external force, the protective effect of the protective net of this application is guaranteed to be implemented normally. Other settings in Embodiment 2 are the same as in Embodiment 1.

[0034] The length, height, and curvature of the lines of the positioning cylinder 7, the protective cover 9, and the inner cylinder 13 in the attached drawings are for illustrative purposes only. Those skilled in the art can make adaptive adjustments according to actual usage.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
