Description

Technical Field

[0001] The invention belongs to the technical field of bank protection support, in particular to a bank protection support device for river ecological protection. Background Art

[0002] With the acceleration of urbanization and frequent human activities, river ecosystems are facing tremendous pressure. River bank protection can prevent the river bank from being washed and eroded by water flow and maintain the stability of the river bank. This is crucial to protecting the buildings, infrastructure and the lives and property of residents on the river bank. For example, during the flood season, bank protection can effectively prevent floods caused by rising river water levels and reduce or avoid property losses and personal injuries suffered by residents due to floods.

[0003] Traditional bank protection projects mostly use hard materials, such as concrete or stone stacking. Although this type of bank protection can resist the erosion of water flow to a certain extent, it seriously damages the natural ecological environment of the river. For example, hard bank protection blocks the material exchange between soil and water, making it difficult for aquatic organisms to live on the shore. It also destroys the habitats of many terrestrial organisms, leading to a reduction in biodiversity.

[0004] Traditional bank protection lacks vegetation coverage, and plant roots are unable to play the role of conserving soil and water, making it easy for riverbank soil to be washed away by rainwater and flow into the river channel, causing soil erosion, which in turn affects the water quality and flood-carrying capacity of the river channel.

[0005] Therefore, river channel ecological protection revetment support devices came into being, but the existing river channel ecological protection revetment support devices are not reasonably designed and lack an effective internal support system. Under the long-term scouring of water flow, fluctuations in water levels, and lateral soil pressure, structural defects such as cavities and cracks are prone to occur inside the revetment. The connections between the components of some revetment structures are not firm, and they are prone to loosening and disconnection under the impact of water flow or other external forces, thus affecting the overall stability of the revetment. Summary of the invention

[0006] In view of the above-mentioned problems, the present invention provides a bank support device for river ecological protection.

[0007] The technical solution of the present invention is: a bank protection support device for river ecological protection, comprising a bank protection body, an internal protection component arranged in the bank protection body, and an external ecological protection component arranged on the side wall of the bank protection body;

[0008] The side wall of the revetment body is provided with a plurality of protection installation openings in a matrix shape, and the internal protection assembly includes a plurality of first protection frames arranged in each of the protection installation openings, a plurality of second protection frames corresponding to the protection installation openings one by one and flush with the surface of the side wall of the revetment body, a vertical protection connecting plate inserted at the upper end of the revetment body and opposite to the inclined surface of the revetment body, a protection horizontal bar arranged on the side wall of the vertical protection connecting plate and located between two adjacent rows of protection installation openings, and a reinforcement connecting piece arranged on the protection horizontal bar and connected to each of the first protection frames adjacent to each other above and below;

[0009] The number of first protection frames arranged in each protection installation opening distributed from top to bottom increases successively, and a grid protection frame distributed in a grid shape is arranged in the first protection frame, and the grid protection frame is filled with protection materials, and the side wall of the second protection frame and flush with the side wall surface of the revetment body is planted with protection plants;

[0010] The external ecological protection component includes a plurality of installation grooves arranged on the left and right sides of the revetment body and distributed sequentially from top to bottom, a protection installation ring arranged in each of the installation grooves, and an external protection net laid on the side wall of the revetment body and connected to each of the protection installation rings.

[0011] Furthermore, the lengths of the protective horizontal bars distributed from top to bottom increase successively, the reinforcing connectors are composed of a plurality of sliding plug-in strips arranged at the upper and lower ends of the protective horizontal bars, and the upper and lower ends of each second protective frame are provided with limiting sliding grooves corresponding one-to-one to the sliding plug-in strips.

[0012] Description: By limiting the lengths of each protective cross bar distributed from top to bottom to increase in sequence, the purpose is to match the horizontal length of the gradually downwardly inclined side of the revetment body, thereby ensuring the supporting effect on the interior of the revetment body, and providing sliding plug-in strips on the protective cross bar that are connected to the upper and lower ends of each second protective frame, thereby further increasing the compactness of the connection between the protective cross bar and the second protective frame, so that the internal protective assembly forms a more stable overall structure, thereby improving the protective effect of the internal protective assembly on the interior of the revetment body, being able to more effectively prevent damage to the internal structure of the revetment body, and extending the service life of the revetment body.

[0013] Furthermore, the left and right sides of the sliding plug strip are provided with serrated limit strips, and the inner wall of the limit sliding groove is provided with limit serrations corresponding to the serrated limit strips.

[0014] Description: When the protective cross bar is connected to the corresponding limiting sliding groove on the second protective frame through the sliding plug-in bar, the mutual misalignment restriction between the serrated limiting bar and the limiting serrations can prevent the lateral displacement of the protective cross bar and the second protective frame after the connection, thereby increasing the connection firmness and more effectively protecting the internal structure of the bank protection body.

[0015] Furthermore, a through hole is provided on the external protective net corresponding to each second protective frame, a clamping ring spreading outward is provided at the upper end of the second protective frame, and a protective clamping frame located at the bottom end of the clamping ring and connected to the clamping ring is provided at the through hole.

[0016] Description: The external protective net shields and protects the side walls of the main body of the revetment, stabilizes the soil, and effectively prevents the loss of soil on the side walls of the main body of the revetment. A through hole is set on the external protective net corresponding to each second protective frame, in order to provide necessary growth space for the protective plants at the second protective frame. A coordinated protection system is formed by the protective plants and the external protective net to jointly improve the protection effect of the side walls of the main body of the revetment. A protective clamping frame connected to a clamping ring is set at the through hole to clamp the external protective net at the through hole to prevent it from loosening or shifting when subjected to external force, thereby enhancing the stability of the external protective net.

[0017] Furthermore, a compression protection frame is connected between two adjacent second protection frames located in the same horizontal direction on the side wall of the revetment body, and a plurality of snap-in recesses are provided on the side wall of the revetment body and corresponding to the lower ends of each frame of the compression protection frame, and a snap-in protrusion corresponding to the snap-in recesses is provided at the lower end of each frame of the compression protection frame.

[0018] Description: Two adjacent second protection frames in the same horizontal direction are connected by a compression protection frame to form a more stable overall structure, which can effectively resist external pressure and impact force and prevent the second protection frame from displacement or deformation, thereby improving the stability and safety of the bank protection body. When installing, the compression protection frame can be clamped together by the one-to-one correspondence between the clamping protrusions and the clamping recesses, which can effectively reduce the position error during the installation process and ensure that the compression protection frame is accurately connected between the two adjacent second protection frames, thereby ensuring the integrity and effectiveness of the entire protection structure.

[0019] Furthermore, each of the compression protection frames located in the same straight line direction is connected by a compression protection strip.

[0020] Note: After connecting the two adjacent second protection frames by means of a compression protection frame, the two adjacent compression protection frames are connected again by means of a compression protection strip, which is equivalent to adding another layer of connection structure on the basis of the original reinforcement. This multi-level reinforcement method can make the entire protection structure more stable, better resist external pressure and impact force, and further reduce the possibility of displacement or deformation of the second protection frame.

[0021] Furthermore, the protective materials filled in the grid protection frame are stones and concrete blocks, and the protective plants planted in the second protection frame are one or more of reeds, water bamboo, calamus, willow, poplar or metasequoia, wherein the weight ratio of stones to concrete blocks is 2 to 3:1.

[0022] Description: The interior of the first protection frame is supported by a grid protection frame to provide a stable frame structure. At the same time, stones and concrete blocks are filled inside it. Stones and concrete blocks are filled in this frame structure. Stones and concrete blocks themselves have a certain weight and hardness, which can further increase the filling density inside the first protection frame, thereby enhancing the overall structural strength of the first protection frame and improving the protection effect on the inside of the revetment body. The second protection frame is set at the opening of the protection installation port on the revetment body, and protective plants are planted on the upper end. The roots of the plants consolidate the soil, reduce slope runoff, and prevent soil erosion. At the same time, the presence of plants can also beautify the environment, provide habitats for wild animals and plants, and promote ecological balance.

[0023] Furthermore, a plurality of buffer platforms are provided on the inclined side walls of the revetment body from top to bottom, each of the buffer platforms is provided with a horizontal water storage trough, and a vertical water guide trough is provided on the inclined side walls of the revetment body, and the bottom end of the vertical water guide trough is connected to the horizontal water storage trough.

[0024] Description: When it rains, the vertical water guide trough on the inclined side wall of the revetment body can guide the rainwater to flow downward. Since its bottom is connected to the horizontal water storage tank, the rainwater will be collected in the horizontal water storage tank. The horizontal water storage tanks on several buffer platforms can disperse and collect the rainwater. When a large amount of rainwater flows down, this dispersed collection method can disperse the concentrated water flow impact force to each horizontal water storage tank, avoiding damage to the revetment body caused by excessive water flow impact force at one place.

[0025] Furthermore, a protective platform structure is provided on the revetment body at the front side of the buffer platform located at the bottom.

[0026] Description: The protective platform structure can change the direction and speed of the water flow, so that it forms a relatively stable flow state at the bottom of the revetment body, reducing the erosion effect of the water flow on the revetment body.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] When the bank protection support device for river ecological protection of the present invention is in use, the protective crossbar is connected to the second protection frame through a reinforcement connecting piece, the sliding plug-in strip of the reinforcement connecting piece cooperates with the limiting sliding groove, and the serrated limiting strips on both sides of the sliding plug-in strip and the limiting serrations are mutually offset and restricted, ensuring the compactness and stability of the connection between the protective crossbar and the second protection frame, effectively preventing lateral displacement, so that the internal protection component forms a stable overall structure, improves the support effect on the interior of the bank protection body, prevents internal structure damage, and extends the service life of the bank protection body; the external protection net of the external ecological protection component is laid on the side wall of the bank protection body through a protection mounting ring, and the through-hole on the protection net is connected to the clamping ring of the second protection frame through a protection clamping frame, which can not only provide growth space for protective plants, but also prevent the protection net from loosening or shifting, stabilize the soil, and reduce soil loss on the side wall of the bank protection body; internal structure damage is prevented by internal protection, and external protection reduces external soil loss. The synergistic effect of internal and external protection reduces the influence of various damaging factors on the bank protection. This comprehensive protection effect enables the revetment to remain in good condition for a longer period of time, effectively extending its service life and reducing its maintenance cost and renewal frequency.

DETAILED DESCRIPTION

[0036] In order to further understand the content of the present invention, the present invention is described in detail below through examples.

[0039] The lengths of the various protective cross bars 23 distributed from top to bottom increase in sequence. The reinforcement connector 24 is composed of a plurality of sliding plug-in strips 240 arranged at the upper and lower ends of the protective cross bars 23. The upper and lower ends of each second protective frame 21 are provided with a limiting sliding groove 200 corresponding to the sliding plug-in strips 240. By limiting the lengths of the various protective cross bars 23 distributed from top to bottom to increase in sequence, the purpose is to match the horizontal length of the gradually downwardly inclined side surface of the revetment body 1 to ensure the supporting effect on the inside of the revetment body 1. The sliding plug-in strips 240 connected to the upper and lower ends of each second protective frame 21 are arranged on the protective cross bars 23, which further increases the compactness of the connection between the protective cross bars 23 and the second protective frames 21, so that the internal protective component 2 forms a more stable overall structure, improves the protective effect of the internal protective component 2 on the inside of the revetment body 1, can more effectively prevent the damage to the internal structure of the revetment body 1, and extend the service life of the revetment body 1.

[0040] like Figure 5 As shown, the left and right sides of the sliding plug strip 240 are provided with serrated limit strips 241, and the inner wall of the limit sliding groove 200 is provided with limit serrations 242 corresponding to the serrated limit strips 241. When the protective horizontal bar 23 is connected with the corresponding limit sliding groove 200 on the second protective frame 21 through the sliding plug strip 240, the serrated limit strip 241 and the limit serrations 242 are mutually displaced and restricted, so that the lateral displacement of the protective horizontal bar 23 and the second protective frame 21 after connection can be prevented, thereby increasing the connection firmness and more effectively protecting the internal structure of the revetment body.

[0041] The number of first protection frames 20 arranged in each protection installation opening 10 distributed from top to bottom increases successively, and a grid protection frame 25 distributed in a grid shape is arranged in the first protection frame 20, and the grid protection frame 25 is filled with protection materials, and the side wall of the second protection frame 21 and flush with the side wall surface of the revetment body 1 is planted with protection plants;

[0042] The protective materials filled in the grid protection frame 25 are stones and concrete blocks, and the protective plants planted in the second protection frame 21 are reeds, water bamboo, calamus, willow, poplar, and metasequoia, wherein the weight ratio of stones to concrete blocks is 2:1. The grid protection frame 25 supports the interior of the first protection frame 20 to provide a stable frame structure, and at the same time, stones and concrete blocks are filled inside it. Stones and concrete blocks are filled in this frame structure. Stones and concrete blocks themselves have a certain weight and hardness, which can further increase the filling density inside the first protection frame 20, thereby enhancing the overall structural strength of the first protection frame 20 and improving the protective effect of the interior of the revetment body 1. The second protection frame 21 is arranged at the opening of the protective installation port 10 on the revetment body 1, and protective plants are planted on the upper end. The roots of the plants can consolidate the soil, reduce slope runoff, and prevent soil erosion. At the same time, the presence of plants can also beautify the environment, provide habitats for wild animals and plants, and promote ecological balance;

[0043] like Figure 2 , 3 As shown, the external ecological protection component 3 includes a plurality of installation grooves 30 arranged on the left and right sides of the revetment body 1 and distributed sequentially from top to bottom, a protection installation ring 31 arranged in each installation groove 30, and an external protection net 32 ​​laid on the side wall of the revetment body 1 and connected to each protection installation ring 31;

The external protection net 32 ​​shields and protects the side wall of the revetment body 1, stabilizes the soil, and effectively prevents the loss of the soil on the side wall of the revetment body 1, and a through hole 320 is provided on the external protection net 32 ​​corresponding to each second protection frame 21. The through opening 320 is used to provide necessary growth space for the protective plants at the second protective frame 21. The protective plants and the external protective net 32 ​​form a coordinated protective system to jointly improve the protective effect of the side wall of the revetment body 1. A protective pressing frame 321 connected to the pressing ring 210 is provided at the through opening 320 to press the external protective net 32 ​​at the through opening 320 to prevent it from loosening or shifting when subjected to external forces such as water flow, wind, etc., thereby enhancing the stability of the external protective net 32;

[0047] S2, the sliding plug strip 240 in the reinforcement connector 24 is connected to the limiting sliding grooves 200 at the upper and lower ends of the second protection frame 21, and the serrated limiting strips 241 on both sides of the sliding plug strip 240 and the limiting serrations 242 on the inner wall of the limiting sliding groove 200 are mutually offset and restricted to prevent the lateral displacement of the protective horizontal strip 23 after being connected to the second protection frame 21, ensuring that the internal protection component 2 forms a stable overall structure;

[0048] S3, planting one or more protective plants selected from reed, water bamboo, calamus, willow, poplar or metasequoia on the side wall of the second protective frame 21, the plant roots consolidate the soil, reduce slope runoff, prevent soil erosion, and beautify the environment;

[0049] S4. A protective mounting ring 31 is arranged in the mounting groove 30 of the external ecological protection component 3, and an external protective net 32 ​​is laid. The external protective net 32 ​​is connected to the protective mounting ring 31 to shield and protect the side wall of the revetment body 1, stabilize the soil, and prevent the soil loss of the side wall of the revetment body 1;

[0050] S5. A through hole 320 is set on the external protective net 32 ​​to provide a growth space for the protective plants at the second protective frame 21, so that the protective plants and the external protective net 32 ​​form a coordinated protection system, and jointly improve the protection effect on the side wall of the bank protection body 1. A protective clamping frame 321 is set at the through hole 320 and connected to the clamping ring 210 at the upper end of the second protective frame 21 to clamp the external protective net 32 ​​at the through hole 320 to prevent it from loosening or shifting when subjected to external forces such as water flow and wind, thereby enhancing the stability of the external protective net 32.

[0051] Embodiment 2: This embodiment differs from Embodiment 1 in that:

[0052] The protective materials filled in the grid protection frame 25 are stones and concrete blocks, and the protective plants planted in the second protection frame 21 are reeds, water bamboo, calamus, willow, poplar and metasequoia, wherein the weight ratio of stones to concrete blocks is 3:1.

[0053] Embodiment 3: This embodiment differs from Embodiment 1 in that:

[0054] like Figure 1 , 4 As shown, a compression protection frame 11 is connected between two adjacent second protection frames 21 on the side wall of the revetment body 1 in the same horizontal direction, and four clamping recesses 12 are provided on the side wall of the revetment body 1 and at the lower ends of each frame corresponding to the compression protection frame 11, and a clamping protrusion 13 corresponding to the clamping recess 12 is provided at the lower end of each frame of the compression protection frame 11;

[0055] Each compression protection frame 11 located in the same straight line direction is connected by a compression protection strip 14. After the two adjacent second protection frames 21 are connected by the compression protection frame 11, the two adjacent compression protection frames 11 are connected again by the compression protection strip 14, which is equivalent to adding another layer of connection structure on the basis of the original reinforcement. This multi-level reinforcement method can make the entire protection structure more stable, better resist external pressure and impact force, and further reduce the possibility of displacement or deformation of the second protection frame 21.

[0056] Three buffer platforms 15 are arranged from top to bottom on the inclined side wall of the revetment body 1, and each buffer platform 15 is provided with a horizontal water storage tank 150.

When rain occurs, the vertical water guide tank 16 on the inclined side wall of the revetment body 1 can guide rainwater to flow downward. Since its bottom end is connected with the horizontal water storage tank 150, rainwater will be collected in the horizontal water storage tank 150. The horizontal water storage tanks 150 on several buffer platforms 15 can disperse and collect rainwater. When a large amount of rainwater flows down, this dispersed collection method can disperse the concentrated water flow impact force to each horizontal water storage tank 150, so as to avoid damage to the revetment body 1 caused by excessive water flow impact force at a certain place;

[0057] A protective platform structure 17 is provided on the front side of the buffer platform 15 located at the bottom of the revetment body 1. The protective platform structure 17 can change the direction and speed of the water flow, so that a relatively stable flow state is formed at the bottom of the revetment body 1, thereby reducing the erosion effect of the water flow on the revetment body 1.
