Description

Technical Field

[0001] This application relates to the field of river water and soil protection, and in particular to a riverbank revetment net. Background Technology

[0002] In natural river channels, particularly in sections with rapid currents, such as river bends, the swift flow often causes severe erosion of the riverbanks, leading to soil erosion, natural widening of the river channel, gradual destruction of surrounding farmland, impact on the surrounding ecological environment, and making restoration difficult.

[0003] Existing methods for preventing soil erosion in rivers include constructing cement retaining walls along riverbanks in sections prone to soil erosion and planting greenery in the area surrounding the cement retaining walls.

[0004] In the process of implementing this application, it was found that the above-mentioned technology has at least the following problems: the cement retaining walls built at the riverbanks are mostly located above the river surface, and the riverbanks below the river surface are still subject to the scouring of the turbulent water flow. Over time, the riverbanks below the cement retaining walls will still suffer from soil erosion, which will lead to the collapse of the riverbanks and the cement retaining walls on them. The planted greenery will also be unable to continue to play a role in preventing soil erosion. It is evident that the methods for preventing soil erosion of riverbanks need to be improved. Summary of the Invention

[0005] To facilitate the prevention of soil erosion along riverbanks, this application provides a riverbank slope protection net.

[0006] The riverbank protection net provided in this application adopts the following technical solution:

[0007] A riverbank protection net includes a wire mesh frame with a partitioned wire assembly connected to the frame. The partitioned wire assembly divides the area within the frame into an erosion prevention zone and a soil reinforcement zone. The erosion prevention zone contains erosion-resistant plastic sheeting connected to the wire mesh frame and the partitioned wire assembly, which covers the riverbank surface above and below the river. The soil reinforcement zone contains a biodegradable retaining net connected to the wire mesh frame and the partitioned wire assembly.

[0008] By adopting the above technical solution, the riverbank protection net is positioned at the riverbank requiring protection, while the anti-erosion plastic sheeting in the anti-erosion zone covers the riverbank surface above and below the river surface. This helps prevent the river water from eroding the soil on the riverbank surface above and below the river surface. At the same time, the biodegradable retaining net in the soil reinforcement zone covers the riverbank surface above the river surface, thus preventing the soil on the riverbank surface above the river surface from sliding into the river. In summary, by preventing the river water from eroding the soil on the riverbank surface above and below the river surface, and by preventing the soil on the riverbank surface above the river surface from sliding into the river, the protection of riverbanks prone to soil erosion is easily achieved.

[0009] In one specific implementation scheme, the anti-erosion plastic oil paper has several water-permeable holes, and the anti-erosion plastic oil paper has a water-permeable cotton layer on the side wall facing the river embankment.

[0010] By adopting the above technical solution, water passage holes are opened on the anti-erosion plastic oil paper to allow some river water to enter the riverbank soil covered by the anti-erosion plastic oil paper. The water-permeable cotton layer helps to prevent the riverbank from suddenly flowing into the river water through the water passage holes. This can achieve the conservation of the riverbank soil, thereby facilitating the reinforcement of the riverbank above and below the river surface.

[0011] In one specific implementation scheme, the anti-erosion zone is provided with a wire mesh bag connected to the wire mesh frame and the partition wire assembly, and the anti-erosion plastic oil paper and the water-permeable cotton layer are both placed in the wire mesh bag.

[0012] By adopting the above technical solution, the steel wire anti-detachment net bag can easily capture the anti-erosion plastic oil paper and the water-permeable cotton layer, thereby playing a positioning role for the anti-erosion plastic oil paper and the water-permeable cotton layer connected in the anti-erosion zone, and improving the stability of the riverbank slope protection net against erosion.

[0013] In one specific implementation scheme, the soil reinforcement zone is provided with a spring net composed of several spring net units, and each spring net unit is provided with the biodegradable soil retaining net.

[0014] By adopting the above technical solution, the spring net composed of several spring net units has high elasticity and is easy to adapt to the uneven conditions of the riverbank.

[0015] In one specific implementation, the spring mesh unit includes at least three connecting rings, with stainless steel springs connecting adjacent connecting rings.

[0016] By adopting the above technical solution, the tightness of the spring mesh unit can be easily achieved through the connecting ring and the stainless steel spring, thereby facilitating the elasticity of the spring mesh.

[0017] In one specific implementation, each of the connecting rings is connected to an elastic cord, and a plurality of the elastic cords are connected together to the biodegradable retaining net located between the stainless steel springs in the spring net unit.

[0018] By adopting the above technical solution, the tension rope helps to prevent the deformation of the biodegradable retaining net when the spring net unit deforms due to the unevenness of the riverbank surface. This helps to prevent the biodegradable retaining net from being damaged due to large deformation and helps to improve the safety and stability of the biodegradable retaining net.

[0019] In one specific implementation, a biodegradable planter is connected to the inner ring of the connecting ring, and the side wall of the biodegradable planter has several interactive holes.

[0020] By adopting the above technical solution, green plants can be planted in biodegradable planters, and the soil in the biodegradable planters can be exchanged with the soil in the river embankment through the interactive holes, thereby improving the stability of the green plants planted on the river embankment, which in turn facilitates the improvement of the ecological environment of the river embankment and enhances the effect of preventing soil erosion.

[0021] In one specific implementation, the inner ring of the connecting ring is provided with a positioning protrusion, and the side wall of the biodegradable plant pot is provided with a positioning groove for the positioning protrusion to be inserted.

[0022] By adopting the above technical solution, the positioning protrusion can be engaged with the corresponding positioning groove to fix the biodegradable plant pot on the connecting ring, thereby improving the stability when initially positioning the biodegradable plant pot on the riverbank.

[0023] In one specific implementation, the corners and edge areas of the wire mesh frame are fixed with several clips.

[0024] By adopting the above technical solution, the snap-fit ​​mechanism facilitates the connection of the riverbank slope protection net with other riverbank slope protection nets, thereby making it easy to change the length and width of the overall slope protection net composed of several riverbank slope protection nets, and thus adapting to the size of the riverbank that needs protection.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Facilitates the prevention of soil erosion along riverbanks;

[0027] 2. Improved the stability of the riverbank slope protection net against scouring and erosion;

[0028] 3. It is easy to adapt to the size of the riverbanks and areas requiring protection. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0040] This application discloses a riverbank revetment mesh. (Refer to...) Figure 1The riverbank protection net includes a steel wire skeleton structure 1, which is divided into an anti-scour zone and an adjacent soil reinforcement zone. The anti-scour zone is equipped with anti-scour components 2 to prevent the soil of the riverbank above and below the river surface from being eroded. The soil reinforcement zone is equipped with soil reinforcement components 3 to reinforce the soil of the riverbank above the river surface. Both the anti-scour components 2 and the soil reinforcement components 3 are connected to the steel wire skeleton structure 1.

[0041] Reference Figure 2 The wire mesh frame structure 1 includes a wire mesh frame 11, which is square in shape. A partitioned wire assembly 12 is connected between a set of parallel frame edges of the wire mesh frame 11. The partitioned wire assembly 12 is used to divide the area inside the wire mesh frame 11 into the aforementioned erosion prevention zone and soil reinforcement zone. Specifically, the partitioned wire assembly 12 includes two wedge rings, referred to as the first wedge ring 121 and the second wedge ring 122, respectively. A first wire 123 is connected between the first wedge ring 121 and one frame edge of the wire mesh frame 11. A second wire 124 is connected between the first wedge ring 121 and the second wedge ring 122. A third wire 125 is connected between the second wedge ring 122 and the other frame edge of the wire mesh.

[0042] It should be noted that the wedge ring is used for the corresponding wedge nail to pass through, and the wedge nail is used to wedge into the soil of the riverbank, thereby facilitating the positioning of the steel wire skeleton structure 1 at the predetermined position on the riverbank.

[0043] It should be noted that the area of ​​the riverbank requiring the coverage of the revetment mesh needs to be determined based on actual conditions through surveying. To ensure that the revetment mesh can completely cover the corresponding riverbank surface, refer to... Figure 3 The steel wire mesh frame 11 has several clips 4 on its corners. Different riverbank slope protection nets can be connected to each other by the clips 4, so that the length and width of the overall slope protection net composed of different riverbank slope protection nets can be flexibly changed so that the overall slope protection net can adapt to the needs of the riverbank size covered by the riverbank slope protection net.

[0044] Reference Figure 4 The anti-erosion component 2 includes a connecting clip 21 connected to the wire mesh frame 11 and the partitioned wire assembly 12. Specifically, the connecting clip 21 includes a wire clip 211 fixed to the wire mesh frame 11, the first wire 123, the second wire 124 and the third wire 125. Each wire clip 211 is fixed with a ring buckle 212. All the above ring buckles 212 are connected to an anti-erosion plastic oil paper 22. The anti-erosion plastic oil paper 22 is used to cover the riverbank from 1m above the river surface to the bottom of the riverbed. The edge of the anti-erosion plastic oil paper 22 is provided with perforations for the corresponding ring buckles 212 to pass through.

[0045] In order to facilitate the continued nourishment of the riverbank covered by the anti-erosion plastic sheet 22, several water passage holes 221 are evenly opened on the anti-erosion plastic sheet 22. Through the water passage holes 221, a small amount of river water in the river channel can still enter the soil of the covered riverbank, thereby continuing to nourish the soil of the riverbank.

[0046] To prevent river water entering the water passage 221 from eroding and washing away the riverbank soil, a water-permeable cotton layer 23 is attached to the side wall of the anti-erosion plastic oil paper 22 close to the riverbank. In this way, the water-permeable cotton layer 23 can facilitate the interaction between the river water in the river channel and the water in the soil layer at the bottom of the riverbank. In addition, the water-permeable cotton layer 23 can also filter the riverbank soil, thereby preventing the soil at the bottom of the riverbank from being eroded and washed away.

[0047] To further enhance the positional stability of the anti-erosion plastic oil paper 22 and the water-permeable cotton layer 23, based on the existing positioning of the anti-erosion plastic oil paper 22 and the water-permeable cotton layer 23 on the steel wire frame structure 1 via the connecting clip 21, and in conjunction with... Figure 5 A wire mesh anti-detachment net bag 24 is wrapped around the wire mesh frame 11 and the partitioned wire mesh assembly 12. Specifically, the wire mesh anti-detachment net bag 24 includes an upper net surface 241 that is pressed onto the upper surface of the anti-erosion plastic oil paper 22, and a lower net surface 242 that is connected to the upper net surface 241 and pressed onto the surface of the water-permeable cotton layer 23 close to the riverbank.

[0048] In implementation, the anti-erosion component 2 is laid on the riverbank in the area from 1m above the river surface to the bottom of the riverbed. The anti-erosion component 2 is positioned by positioning the entire riverbank slope protection net. The positioning method of the entire riverbank slope protection net includes: First, passing the pre-set wedge nails that are used with the wedge rings through the corresponding wedge rings and wedging them into the riverbank to position the entire riverbank slope protection net; Second, passing the pre-set wedge nails that can pass through the clips 4 connected to the wire mesh frame 11 through the corresponding clips 4 and wedging them into the riverbank soil until they are fixed to a fixed state to position the entire riverbank slope protection net; Third, both passing the wedge nails that are used with the wedge rings through the corresponding wedge rings and wedging them into the riverbank, and passing the wedge nails that can pass through the clips 4 connected to the wire mesh frame 11 through the corresponding clips 4 and wedging them into the riverbank soil to position the entire riverbank slope protection net.

[0049] After the overall positioning of the riverbank protection net is completed, on the one hand, the river water in the channel is difficult to directly scour the riverbank which is prone to soil erosion, but can only scour the anti-scour plastic oil paper 22. This helps to prevent the soil covered by the anti-scour plastic oil paper 22 from being further lost. On the other hand, through the water passage holes 221 on the anti-scour plastic oil paper 22, the water in the channel can interact with the water in the soil at the bottom of the riverbank, thereby nourishing the soil at the bottom of the riverbank and improving the stability of the soil at the bottom of the riverbank. The setting of the permeable cotton layer 23 can prevent the soil on the bottom wall of the riverbank from being lost through the water passage holes 221 while water is interacting.

[0050] Reference Figure 6 The soil reinforcement component 3 includes a spring net 31 composed of several spring net units 311, which is used to trap the soil on the riverbank surface above the river level; combined with Figure 7 Taking one of the spring mesh units 311 as an example, in this embodiment, the spring mesh unit 311 includes four connecting rings 3111. The centers of the four connecting rings 3111 are respectively located at the four corners of a preset square. Each connecting ring 3111 is connected to the two connecting rings 3111 closest to it by a stainless steel spring 3112. The four stainless steel springs 3112 correspond one-to-one with the four sides of the preset square and are located on the corresponding sides of the preset square. The four connecting rings 3111 and the four stainless steel springs 3112 form a square frame.

[0051] The spring net 31, composed of spring net units 311, has appropriate elasticity and can adapt to the unevenness of the riverbank, thereby facilitating the capture of the riverbank soil, improving the stability of the riverbank soil, and preventing soil loss above the river surface.

[0052] To prevent soil from escaping from the area within the box mentioned above, refer to... Figure 8 Each spring net unit 311 has four connecting rings 3111 connected to elastic ropes 32. The ends of the four elastic ropes 32 away from their respective connecting rings 3111 are connected to a biodegradable retaining net 33. The elastic ropes 32 allow the biodegradable retaining net 33 to adapt to the unevenness of the riverbank without causing significant deformation. This allows the biodegradable retaining net 33 to not only prevent soil from escaping from the frame area, but also to avoid deformation that could damage it due to the unevenness of the soil.

[0053] Reference Figure 9Each connecting ring 3111 has a positioning protrusion 5 coaxially connected to its inner ring wall. Each connecting ring 3111 has a through hole for inserting a corresponding biodegradable planter 6. The biodegradable planter 6 contains plants such as flowers and grasses used to improve the ecological environment of the riverbank. Each planter 6 has a positioning groove 61 on its side wall for the corresponding positioning protrusion 5 to extend into. Each biodegradable planter 6 has an interactive hole 62 on its side wall and bottom wall. The interactive hole 62 allows for the exchange of soil and water between the planter 6 and the riverbank soil and water outside the planter before the planter 6 degrades.

[0054] In implementation, the biodegradable planter 6 is inserted into the corresponding connecting ring 3111, thus positioning the biodegradable planter 6 on the corresponding connecting ring 3111; then, the riverbank protection netting is laid on the corresponding riverbank surface, followed by manually burying the biodegradable planter 6 in the riverbank and planting greenery in the biodegradable planter 6; during the stage before the biodegradable planter 6 degrades, the interaction between the sidewall and bottom wall of the biodegradable planter 6 facilitates the interaction between the soil and water inside the planter and the soil and water of the riverbank outside the planter, thus making it easier for the biodegradable planter 6 to initially integrate with the riverbank; subsequently, after the biodegradable planter 6 has basically degraded, the soil and water inside the biodegradable planter 6 will also completely integrate with the soil and water of the riverbank, thus achieving stable rooting of the greenery on the riverbank, which not only improves the ecological environment. The horizontal effect also helps prevent soil erosion along riverbanks. It should be noted that existing technologies often achieve the purpose of preventing soil erosion by directly planting greenery on the riverbanks. However, this does not take into account that the planted greenery needs a certain growth period to play a role in preventing soil erosion. Therefore, as the process of soil erosion progresses, the planted greenery will also disappear. In this application, the greenery is first planted in biodegradable plant pots 6 and then fixed on spring nets 31. This can prevent the greenery from moving due to water loss when the roots are not yet firmly established. During the degradation process of the biodegradable plant pots 6, the greenery fixed in a certain position will gradually complete the rooting process and gradually play a role in preventing soil erosion.

[0055] The implementation principle of a riverbank protection net in this application embodiment is as follows: the riverbank protection net is fixed at the riverbank where soil erosion is prone, and the anti-scour component 2 is fixed in the area from the upper and lower positions of the river surface to the bottom of the riverbed. The anti-scour component 2 can prevent the river water from continuing to impact the easily eroded soil of the riverbank, and at the same time, it can also achieve the function of conserving the soil at the bottom of the riverbank, thereby enhancing the stability of the soil at the bottom of the riverbank and making it less prone to erosion. At the same time, the soil reinforcement component 3 is fixed on the surface of the riverbank above the river surface. While it can help to block easily eroded soil, it can also improve the ecological environment and prevent soil erosion by planting green plants.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
