Description

Technical Field

[0001] This utility model relates to the field of loess slope restoration technology, and in particular to a vegetation net mat for loess slope restoration. Background Technology

[0002] Due to its soil characteristics, the loess region has loose soil with large pores and poor resistance to erosion. Under the influence of natural factors (such as rainfall and wind erosion) and human factors (such as over-cultivation and engineering construction), soil erosion on loess slopes is extremely serious. For example, in the construction of highways in some mountainous areas, loess slopes formed by excavating mountains often lack timely and effective protective measures. During rainfall, large amounts of soil are washed away, leading to the destruction of the slope's soil structure and even triggering geological disasters such as landslides. This not only damages the local ecological environment but also threatens the surrounding infrastructure and the safety of residents.

[0003] Currently, one type of vegetation netting for loess slope restoration uses support blocks for fixing the two ends of the netting body. However, the length of the support blocks is fixed, making it inconvenient to connect and adjust them. Furthermore, the support blocks are only used for single fixing, resulting in limited functionality and poor practicality. In addition, another type of vegetation netting for loess slope restoration uses multiple positioning bolts to fix the position of the netting body. Due to the mesh structure of the netting body, the positioning bolts may become unstable, further reducing its practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the two ends of the main body of the netting are fixed by support blocks. The length of the support blocks is fixed, which is inconvenient for docking and adjustment. In addition, the support blocks are only used for single fixation and have limited functions. The main body of the netting is fixed by multiple positioning bolts. However, due to the grid structure of the main body of the netting, the positioning bolts may be unstable. Therefore, this utility model proposes a vegetation netting for loess slope restoration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vegetation netting for loess slope restoration, comprising two first support blocks, a second support block installed at one end of the first support block, a flow groove being provided in both the second and first support blocks, a connecting groove being provided on one side of the flow groove at one end of both the second and first support blocks, a clamping plate being fixed at the other end of both the second and first support blocks, a netting body being provided between the two sets of clamping plates, and multiple mounting sleeves being installed in the netting body.

[0006] Preferably, the main body of the netting has a vegetation layer, a substrate layer is attached and fixed to the bottom of the vegetation layer, a netting layer is attached and fixed to the bottom of the substrate layer, and an isolation layer is fixed to the bottom of the netting layer.

[0007] Preferably, both ends of the first support block are fixed with snap-fit ​​plates, and both ends of the second support block are provided with snap-fit ​​grooves that match the snap-fit ​​plates. The snap-fit ​​plates are fixed to the second support block by bolts.

[0008] Preferably, a protective sleeve is fixed on the inner wall of the second support block outside the bolt, and both the snap-fit ​​plate and the second support block are provided with screw holes that match the bolt.

[0009] Preferably, both the snap-fit ​​plate and the second support block have screw holes that match the bolts.

[0010] Preferably, the card plate has multiple mounting holes, and the first support block and the second support block are both fixed with a baffle plate on the inner wall of the connecting groove, and the two flow grooves are connected.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the snap-fit ​​plate, snap-fit ​​groove, and bolts allow for the arbitrary connection of different first and second support blocks according to actual needs, facilitating adjustments based on the length of the netting body and enhancing practicality. The flow channel and connecting channel guide rainwater from the slope top during rain, allowing it to flow through the connecting channel into the flow channel for drainage, preventing rainwater erosion and slope collapse. This enhances functionality. Furthermore, the mounting sleeve, installed inside the netting body, prevents deformation such as enlargement when the positioning pin penetrates the sleeve to fix the netting body, ensuring stable positioning of the netting body.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-4 As shown, this utility model provides a vegetation netting for loess slope restoration, including two first support blocks 1. A second support block 2 is installed at one end of the first support block 1. Both the second support block 2 and the first support block 1 have flow grooves 7. One end of the second support block 2 and the first support block 1 has a connecting groove 8 on one side of the flow groove 7. The other end of the second support block 2 and the first support block 1 is fixed with a clamping plate 10. A netting body 13 is provided between the two sets of clamping plates 10. Multiple mounting sleeves 14 are installed inside the netting body 13.

[0021] The overall effect of Embodiment 1 is that, through the setting of the flow channel 7 and the connecting channel 8, rainwater on the top of the slope can be guided during rain, allowing the rainwater to flow into the flow channel 7 through the connecting channel 8 and be discharged, thus preventing rainwater from eroding the top of the slope and causing the slope to collapse. It is more functional. With the setting of the mounting sleeve 14, and the mounting sleeve 14 is installed inside the netting body 13, when the positioning pin passes through the mounting sleeve 14 to fix the netting body 13 in position, the mounting sleeve 14 will not expand or deform, so that the positioning pin can stably fix the position of the netting body 13.

[0022] Example 2, as Figure 1-4As shown, the main body 13 of the netting has a vegetation layer 15 inside. The bottom end of the vegetation layer 15 is attached to and fixed with a matrix layer 16. The bottom end of the matrix layer 16 is attached to and fixed with a net body layer 17. The bottom end of the net body layer 17 is fixed with an isolation layer 18. Both ends of the first support block 1 are fixed with snap-fit ​​plates 3. Both ends of the second support block 2 are provided with snap-fit ​​grooves 4 that match the snap-fit ​​plates 3. The snap-fit ​​plates 3 are fixed to the second support block 2 by bolts 5. The inner wall of the second support block 2 is fixed with a protective sleeve 6 outside the bolts 5. Both the snap-fit ​​plates 3 and the second support block 2 are provided with screw holes 12 that match the bolts 5. Both the snap-fit ​​plates 3 and the second support block 2 are provided with screw holes 12 that match the bolts 5. The snap-fit ​​plate 10 is provided with multiple mounting holes 11. Both the first support block 1 and the second support block 2 are fixed with a barrier plate 9 on the inner wall of the connecting groove 8. The two flow grooves 7 are connected.

[0023] The overall effect of Embodiment 2 is as follows: the vegetation layer 15 contains selected plant seeds suitable for slope environment growth. These seeds are drought-resistant, cold-resistant, and tolerant of poor soil, and can germinate and grow under relatively harsh environmental conditions on the slope. The substrate layer 16 provides the necessary material basis for the germination of vegetation seeds and the growth of seedlings. The isolation layer 18 is mainly used to prevent adverse interactions between the vegetation netting and the slope soil, making it more practical. The mounting holes 11 allow screws to be inserted to fix both ends of the netting body 13. The snap-fit ​​plate 3, snap-fit ​​groove 4, and bolts 5 allow different first support blocks 1 and second support blocks 2 to be connected according to actual needs, making it easy to adjust according to the length of the netting body 13, making it more practical. The barrier plate 9 prevents soil from the top of the slope from entering the flow channel 7 and causing blockage. The protective sleeve 6 protects and isolates the bolts 5, preventing water in the flow channel 7 from corroding the bolts 5.

[0024] Working principle: When using this device, the main body 13 of the netting is placed on a slope. First support blocks 1 and second support blocks 2 are placed at both ends of the main body 13. Screws are driven into the mounting holes 11 of the clamping plate 10 to fix both ends of the main body 13. The first support blocks 1 and second support blocks 2 are fixed in position by pre-embedded or external screws. Through the clamping plate 3, clamping groove 4, and bolts 5, different first support blocks 1 and second support blocks 2 can be freely connected according to actual needs, facilitating adjustments based on the length of the main body 13. The adjustment enhances practicality. The inclusion of the flow channel 7 and connecting channel 8 allows rainwater to be guided from the top of the slope during rainfall. The rainwater flows through the connecting channel 8 into the flow channel 7 for drainage, preventing rainwater erosion and slope collapse. Furthermore, the installation sleeve 14, installed inside the netting body 13, ensures that the sleeve will not expand or deform when the positioning pin penetrates it to fix the netting body 13. This allows the positioning pin to stably fix the netting body 13 in place.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
