Description

Technical Field

[0001] This utility model relates to the field of protective embankment technology, specifically a vegetation net protective embankment. Background Technology

[0002] Traditional embankment protection primarily utilizes rigid materials such as concrete and masonry. While these methods can ensure embankment stability to a certain extent, they have numerous drawbacks, including significant environmental damage, negative impacts on the landscape, and high maintenance costs. With increasing environmental awareness and higher demands for ecological quality, there is an urgent need for a protective technology that effectively protects embankments while also providing ecological benefits. Vegetated netting embankment protection technology has emerged to address this need. It leaves 90% of the space available for filling with soil, gravel, and fine stones, allowing plant roots to grow comfortably, neatly, and evenly. Once fully grown, the turf firmly bonds the netting, turf, and soil surface, forming a robust, green, composite protective layer.

[0003] However, vegetation nets are usually fixed to the slope using anchors. Whether it is a traditional U-shaped nail or a straight rod anchor, they lack barbs or expansion structures, and have limited friction with the soil. As a result, they are easily pulled out in whole during strong winds and rainstorms due to insufficient soil pull-out resistance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vegetation net for protecting road embankments, which solves the problem mentioned in the background technology that the anchor nails have limited friction with the soil, making them easy to be pulled out as a whole during strong winds and rainstorms due to insufficient soil pull-out resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vegetation netting embankment, including a retaining wall, on which a three-dimensional vegetation netting is laid. The three-dimensional vegetation netting is fixed to the retaining wall by fasteners, which consist of an insert and a pusher. The insert includes an insert rod with a cavity inside. The periphery of the cavity is connected to the outside through perforations. Anti-slip nails are slidably installed in the perforations. One end of the anti-slip nail is connected to a compression rod through a limiting plate. The limiting plate is connected to the inner wall of the perforation through a spring. The pusher includes a push rod that is adapted to the cavity.

[0006] Preferably, a guide block is provided at the top of the cavity, and the guide block corresponds to the perforation.

[0007] Preferably, the lower end of the push rod is conical, and a vertical guide groove is provided on the periphery of the push rod, the guide groove being adapted to the guide block.

[0008] Preferably, the top end of the insertion rod is provided with a threaded tube.

[0009] Preferably, a top cover is rotatably mounted on the top of the push rod, and the top cover is helically connected to a threaded tube.

[0010] This utility model provides a vegetation net for protecting road embankments. It has the following beneficial effects:

[0011] (1) This utility model pushes the squeezing rod with the push rod, and the squeezing rod drives the limiting plate to squeeze the spring, so that the anti-slip nails pass through the through hole and extend out of the insertion rod, penetrating deep into the soil. The anti-slip nails greatly increase the degree of engagement with the soil, effectively preventing the vegetation net from being pulled out as a whole due to insufficient soil pull-out resistance in bad weather.

[0012] (2) After the push rod pushes the squeezing rod to fix the anti-slip nail in place, the top cover is rotated to make it tightly connected with the threaded tube, and the push rod is firmly locked on the insertion rod to prevent the push rod from loosening or coming out under the action of the external environment, thereby avoiding the anti-slip nail from retracting and ensuring that the vegetation net is continuously and stably fixed on the embankment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figures 1-4 This utility model provides a vegetation net protection embankment, including an embankment 1, on which a three-dimensional vegetation net 2 is laid. The three-dimensional vegetation net 2 is fixed to the embankment 1 by a fixing member 3. The fixing member 3 consists of an insert 31 and a push-in member 32. The insert 31 includes an insert rod 311, and the insert rod 311 has a cavity 312 inside. The periphery of the cavity 312 is connected to the outside through a perforation 315. An anti-slip nail 316 is slidably installed in the perforation 315. One end of the anti-slip nail 316 is connected to a compression rod 318 through a limiting plate 317. The limiting plate 317 is connected to the inner wall of the perforation 315 through a spring 319. The push-in member 32 includes a push rod 321, which is correspondingly adapted to the cavity 312.

[0023] A guide block 314 is provided at the top of the cavity 312, and the guide block 314 corresponds to the through hole 315.

[0024] The lower end of the push rod 321 is conical, and a vertical guide groove 322 is provided on the periphery of the push rod 321. The guide groove 322 is adapted to the guide block 314.

[0025] The top of the insertion rod 311 is provided with a threaded tube 313.

[0026] A top cover 323 is rotatably mounted on the top of the push rod 321, and the top cover 323 is screwed to the threaded tube 313.

[0027] Specifically, the three-dimensional vegetation net 2 is laid on and covered on the surface of the embankment 1. The insertion rod 311 of the insert 31 is passed through the corresponding hole on the three-dimensional vegetation net 2 and inserted into the embankment 1, so that the insertion rod 311 is initially fixed in the soil of the embankment 1. The push rod 321 is inserted into the cavity 312 of the insertion rod 311. The conical design at the lower end of the push rod 321 makes it easy to insert. The guide groove 322 on the periphery of the push rod 321 is adapted to the guide block 314 at the top of the cavity 312. During the insertion process, the guide block 314 is embedded in the guide groove 322 to ensure that the push rod 321 is inserted in the correct direction.

[0028] During the insertion of push rod 321, push compression rod 318 to drive limit plate 317 to compress spring 319, causing anti-slip nail 316 to extend from perforation 315 to the outside of insertion rod 311 and penetrate deep into the soil of embankment 1. Anti-slip nail 316, like barbs, tightly engages with the soil, firmly fixing the three-dimensional vegetation net 2 to embankment 1;

[0029] After the push rod 321 is fully inserted, rotate the top cover 323 at the top of the push rod 321 so that it is screwed into the threaded tube 313 at the top of the insertion rod 311, and firmly lock the push rod 321 onto the insertion rod 311 to prevent the push rod 321 from loosening or coming out, and ensure that the anti-slip nail 316 remains in the extended state to maintain the fixation of the three-dimensional vegetation net 2.

[0030] By embedding the anti-slip nails 316 deep into the soil, the friction and interlocking force with the soil are increased. Compared with traditional anchor nails, the fixing effect is significantly improved, effectively preventing the three-dimensional vegetation net 2 from being pulled out as a whole in severe weather such as strong winds and heavy rain. At the same time, the anti-slip nails 316 extending in multiple directions form a fixing structure similar to expansion, realizing multi-point fixing, making the vegetation net evenly stressed, and further improving stability.

[0031] The cooperation between the guide block 314 and the guide groove 322 ensures the accuracy of the insertion of the push rod 321, so that the anti-slip nail 316 can extend evenly from the through hole 315, avoiding problems such as uneven force and inconsistent extension length of the anti-slip nail 316 due to the offset of the push rod 321, and ensuring the reliability of the fixing effect.

[0032] The conical design at the bottom of the push rod 321 reduces insertion resistance, making it easier for construction workers to operate and improving construction efficiency. The spiral connection between the threaded tube 313 and the top cover 323 facilitates quick installation and disassembly, saving time and labor costs during the laying and subsequent maintenance of the vegetation net.

[0033] Working principle: The three-dimensional vegetation net 2 is laid flat on the surface of the embankment 1, so that the vegetation net completely covers the area to be protected. Then, according to the design spacing, the fixing points are marked on the vegetation net. The insertion rod 311 of the insert 31 is inserted vertically into the soil of the embankment 1 through the corresponding hole of the three-dimensional vegetation net 2. After reaching the predetermined depth, the insertion rod 311 is initially fixed by the friction between itself and the soil. The push rod 321 of the pusher 32 is picked up, and its conical shape at the bottom is used to align the push rod 321 with the opening of the cavity 312 of the insertion rod 311. During the insertion process, the guide block 314 at the top of the cavity 312 is embedded in the guide groove 322 on the side of the push rod 321, guiding the push rod 321 to be inserted smoothly in a straight line like a track, avoiding deviation or jamming.

[0034] As the push rod 321 penetrates deeper into the cavity 312, its bottom gradually contacts and pushes the compression rod 318. The compression rod 318 drives the limiting plate 317 to compress the spring 319. Freed from the constraint of the spring 319, the anti-slip nails 316, pushed by the limiting plate 317, quickly extend from the perforation 315 and pierce the soil of the embankment 1. The anti-slip nails 316, extending in multiple directions, grip the soil tightly like barbs, firmly connecting the three-dimensional vegetation net 2 to the embankment 1 from multiple points. After the push rod 321 is fully inserted, the top cover 323 at the top of the push rod 321 is rotated. The top cover 323 engages with the threaded tube 313 at the top of the insertion rod 311 through threads. As the top cover 323 tightens, the push rod 321 is firmly locked inside the insertion rod 311, preventing it from loosening and exiting due to external force, ensuring that the anti-slip nails 316 remain extended, continuously stabilizing the three-dimensional vegetation net 2.
