Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a quick-assembly protective net for the protection and management of saline soil slopes. Background Technology

[0002] Saline soil slopes are susceptible to wind erosion, rain, and freeze-thaw cycles due to their high salt content, leading to loosening, peeling, and even landslides of the surface soil. Traditional protective structures (such as concrete grids and masonry) suffer from problems such as long construction periods, poor adaptability, and high maintenance costs.

[0003] Although existing modular protective nets can be assembled quickly, they are prone to loosening under salt and alkali corrosion and vibration environments, resulting in a decrease in the overall integrity of the protective net. The net panels lack a supporting structure and are prone to fatigue and breakage after long-term scouring. Most existing protective nets are integral structures, which require replacement of the entire piece after damage, increasing maintenance costs.

[0004] Therefore, there is an urgent need for a protective net that can resist salt and alkali corrosion, adapt to vibration environments, has a good support structure, and is easy to repair and replace locally. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a quick-assembly protective net for the protection and management of saline soil slopes.

[0006] The technical solution of this utility model is: a quick-assembly protective net for the protection and treatment of saline soil slopes, including several protective frames, locking connectors for connecting two adjacent protective frames, and a protective net plate snapped into the protective frame;

[0007] The protective frame adopts a regular polygon structure with an even number of sides, and one half of the side walls of the protective frame are provided with insertion recesses, while the other half of the side walls are provided with insertion strips corresponding to the insertion recesses.

[0008] The locking connector includes a U-shaped locking rod that passes through the insertion notch and the corresponding insertion strip, a locking block with a through insertion interface on the side wall corresponding to the two free ends of the U-shaped locking rod, and elastic posts on the two free ends of the U-shaped locking rod.

[0009] Furthermore, the protective mesh panel includes an outer mounting frame snapped into the protective frame, a protective mesh disposed within the outer mounting frame, and several protective rods disposed within the outer mounting frame and located at the bottom of the protective mesh and distributed in an alternating manner.

[0010] Instructions: When using the protective netting, the outer frame is snapped into the protective frame for secure installation, facilitating quick disassembly or replacement of the netting and ensuring its protective effect on saline soil slopes. The netting prevents saline soil from being washed away by wind erosion, rain, or water flow, reducing the risk of soil erosion. Protective rods are installed at the bottom of the netting to distribute the stress, reducing wear or fatigue damage and lowering the frequency of replacement.

[0011] Furthermore, the protective frame has receiving recesses on both the front and rear sides corresponding to the insertion recess position. The horizontal section of the U-shaped locking rod is placed in the receiving recess on the front side of the protective frame, and the locking block is placed in the receiving recess on the rear side of the protective frame.

[0012] Explanation: When two adjacent protective frames are connected by a locking connector, a U-shaped locking rod passes through both protective frames. The through-hole interface on the locking block is aligned with the free end of the U-shaped locking rod and pushed in. At this time, the elastic columns on the two free ends of the U-shaped locking rod are compressed at the corresponding through-hole interfaces and slide along the through-hole interfaces. When the elastic columns slide out of the through-hole interfaces, the elasticity is restored and the locking block and U-shaped locking rod are fixed in place. The above process realizes the rapid installation, vibration resistance, corrosion resistance and maintenance-free operation of adjacent protective frames in the saline soil slope protection system through the elastic self-locking mechanism. It is especially suitable for long-term stable use in harsh outdoor environments. By setting receiving recesses on the front and back sides of the protective frame and placing the horizontal section of the U-shaped locking rod and the locking block in the corresponding receiving recesses, on the one hand, there are no exposed protrusions, making the outer surface of the protective frame smooth, reducing the risk of sharp corner scratches, and improving aesthetics. On the other hand, it provides buffer space for the U-shaped locking rod and the locking block to avoid connection failure due to deformation.

[0013] Furthermore, the two elastic columns are distributed on the outer walls of the two free ends of the U-shaped locking rod, and an arc-shaped sliding surface is provided at the end position of the elastic column.

[0014] Explanation: By placing the elastic posts on the outer walls of the two free ends of the U-shaped locking rod, it is convenient for workers to compress the two elastic posts simultaneously and push the two free ends of the U-shaped locking rod at the same time during disassembly, so as to separate it from the locking block. This simplifies the disassembly process and improves maintenance efficiency. At the same time, by limiting the end position of the elastic posts to an arc-shaped sliding surface, when the arc-shaped sliding surface contacts the inner wall of the through insertion interface of the locking block, the compression process is guided by the curved surface, avoiding the jamming phenomenon caused by right-angle edges, making the elastic posts easier to press in.

[0015] Furthermore, the inner wall of the through-hole interface of the locking block is provided with anti-slip texture.

[0016] Explanation: The anti-slip texture increases the static friction between the elastic column and the inner wall of the through-hole interface, preventing the elastic column from unexpectedly retracting and causing the connection to loosen when the slope is subjected to wind vibration, water flow, or vehicle traffic vibration.

[0017] The beneficial effects of this utility model are:

[0018] This utility model of a quick-assembly protective net for saline soil slope protection and management utilizes a modular design with interlocking notches, interlocking strips, and U-shaped locking rods to achieve rapid alignment and connection between adjacent protective frames. Combined with a self-locking mechanism of elastic posts, the connection is highly reliable and does not require loosening. During maintenance, simply pressing the elastic posts on both sides unlocks the net, allowing for tool-free fixing and significantly improving field construction efficiency. Furthermore, the protective frame adopts a regular polygonal structure with an even number of sides, allowing for free combination according to the slope gradient to form continuous or stepped protective surfaces. Simultaneously, the protective net panels and frames employ a snap-fit ​​separation design, facilitating individual replacement of damaged net panels and reducing maintenance frequency and costs in saline soil environments. The staggered distribution of the protective rods distributes the stress on the net, reducing localized stress concentration and extending the net's service life. Attached Figure Description

Detailed Implementation

[0025] Example 1: As Figure 1 , 2As shown, a quick-assembly protective net for the protection and treatment of saline soil slopes includes several protective frames 1, locking connectors 2 for connecting two adjacent protective frames 1, and protective net panels 3 snapped into the protective frames 1. The protective frames 1, locking connectors 2 and protective net panels 3 can be made of stainless steel or engineering plastics, and the surfaces are coated with epoxy resin anti-corrosion coating to resist salt and alkali corrosion.

[0026] like Figure 3 As shown, the protective frame 1 adopts a regular polygon structure with an even number of sides, such as a regular quadrilateral, a regular hexagon, or a regular octagon. One half of the side walls of the protective frame 1 are provided with insertion recesses 10, and the other half of the side walls are provided with insertion strips 11 corresponding to the insertion recesses 10.

[0027] like Figure 5 As shown, the locking connector 2 includes a U-shaped locking rod 20 that passes through the insertion notch 10 and the corresponding insertion strip 11, a locking block 21 with a through insertion interface 210 on the side wall corresponding to the two free ends of the U-shaped locking rod 20, and elastic posts 200 on the two free ends of the U-shaped locking rod 20.

[0028] Two elastic posts 200 are distributed on the outer walls of the two free ends of the U-shaped locking rod 20, and an arc-shaped sliding surface 201 is provided at the end of the elastic post 200. By setting the elastic posts 200 on the outer walls of the two free ends of the U-shaped locking rod 20, it is convenient for workers to compress the two elastic posts 200 at the same time and push the two free ends of the U-shaped locking rod 20 at the same time during disassembly, so as to separate it from the locking block 21, simplifying the disassembly process and improving maintenance efficiency. At the same time, by limiting the end position of the elastic post 200 to an arc-shaped sliding surface 201, when the arc-shaped sliding surface 201 contacts the inner wall of the through insertion interface 210 of the locking block 21, the compression process is guided by the curved surface, avoiding the jamming phenomenon caused by right-angle edges, making it easier for the elastic post 200 to be pressed in.

[0029] The inner wall of the through-hole interface 210 of the locking block 21 is provided with anti-slip texture. The anti-slip texture increases the static friction between the elastic column 200 and the inner wall of the through-hole interface 210, preventing the elastic column 200 from accidentally retracting and causing the connection to loosen when the slope is vibrated by wind, water flow or vehicle traffic.

[0030] like Figure 4As shown, the protective netting panel 3 includes an installation frame 30 that is snapped into the protective frame 1, a protective netting 31 that is installed in the installation frame 30, and three protective rods 32 that are installed in the installation frame 30 and located at the bottom of the protective netting 31 and are staggered. When the protective netting panel 3 is in use, the installation frame 30 is snapped into the protective frame 1 for fixed installation, which facilitates quick disassembly or replacement of the protective netting 31, ensuring the protective effect on the saline soil slope. The protective netting 31 prevents the saline soil from being lost due to wind erosion, rain or water erosion, reducing the risk of soil erosion. The protective rods 32 installed at the bottom of the protective netting 31 reduce the wear or fatigue damage of the protective netting 31 by sharing the force of the protective netting 31, thus reducing the replacement frequency.

[0031] The protective frame 1 has receiving recesses 12 on both the front and rear sides corresponding to the insertion recesses 10. The horizontal section of the U-shaped locking rod 20 is placed in the receiving recess 12 on the front side of the protective frame 1, and the locking block 21 is placed in the receiving recess 12 on the rear side of the protective frame 1. By setting receiving recesses 12 on the front and rear sides of the protective frame 1 and placing the horizontal section of the U-shaped locking rod 20 and the locking block 21 in the corresponding receiving recesses 12, on the one hand, there are no exposed protrusions, making the outer surface of the protective frame 1 smooth, reducing the risk of sharp corner scratches, and improving the aesthetics. On the other hand, it provides buffer space for the U-shaped locking rod 20 and the locking block 21 to avoid connection failure due to deformation.

[0032] The installation method of the quick-assembly protective net for saline soil slope protection and treatment of this utility model includes the following steps:

[0033] S1. Insert the outer frame 300 into each protective frame 1, take one of the protective frames 1, and connect several protective frames 1 to each insertion recess 10 on the side wall of the protective frame 1 through the insertion strip 11. Then, connect several protective frames 1 to the outside of each insertion strip 11 on the side wall of the protective frame 1 by sleeve insertion recess 10.

[0034] S2. The U-shaped locking rod 20 is inserted through the two adjacent protective frames 1, and the through insertion interface 210 on the locking block 21 is aligned with the free end of the U-shaped locking rod 20 and pushed in. At this time, the elastic columns 200 on the two free ends of the U-shaped locking rod 20 are compressed in the corresponding through insertion interface 210 and slide along the through insertion interface 210. When the elastic column 200 slides out of the through insertion interface 210, the elasticity is restored and the locking block 21 and the U-shaped locking rod 20 are limited and fixed.

[0035] S3. Securely install the connected protective frames 1 onto the saline soil slope for protection.
