Description

Technical Field

[0001] The utility model relates to the technical field of river slope protection structures, in particular to a riverbed bank protection structure. Background Art

[0002] With the development of cities and the increasing awareness of environmental protection, the design of urban river bank protection has increasingly taken into account the protection of the ecological environment. For example, the current river bank protection is equipped with an ecological retaining wall. By setting holes on the water-facing side of the ecological retaining wall and setting the ecological retaining wall as a multi-gradient structure, each gradient structure is backfilled with planting soil and then planted with green plants, so that aquatic organisms in the river can have better growth and habitat space, thereby achieving the effect of ecological protection.

[0003] While existing ecological retaining wall structures offer numerous advantages, such as ecological, environmental, and aesthetic advantages, in practice, holes and cavities on the waterfront side of the ecological retaining wall can easily cause backfill soil to be lost due to erosion by river and rainwater, resulting in damage to the bank protection structure. Furthermore, because ecological retaining walls are primarily composed of stacked concrete blocks, the connections between the concrete blocks are unstable, resulting in poor overall stability and protection of the riverbed slope. Therefore, it is necessary to improve the existing ecological retaining wall structure to enhance its stability. Utility Model Content

[0004] The utility model aims to provide a riverbed bank protection structure to solve the problem of poor stability of the ecological retaining wall arranged on the riverbed bank protection in the prior art.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions: a riverbed bank protection structure, including an inclined slope, with an anti-filtration structure and an ecological retaining wall arranged in sequence outside the slope, the ecological retaining wall including multiple layers of ecological protection layers, the multiple layers of ecological protection layers are arranged along the inclination direction of the slope, each layer of ecological protection layer includes multiple ecological blocks, the ecological blocks are provided with an ecological containment structure connected to the water-facing side of the ecological blocks, horizontal connecting parts are provided between adjacent ecological blocks in the same layer of ecological protection layer, and vertical connecting parts are provided between the upper and lower adjacent layers of ecological protection layers.

[0006] The principle and beneficial effects of this solution are: in this application, an anti-filtration structure and an ecological retaining wall are arranged in sequence outside the slope. The anti-filtration structure is located between the ecological retaining wall and the slope. The use of the anti-filtration structure can reduce soil and water loss on the slope; at the same time, the ecological retaining wall in this application is composed of multiple layers of ecological protection layers. The multiple layers of ecological protection layers are arranged along the inclination direction of the slope. The top surface of the lower ecological protection layer protrudes a certain distance from the bottom end of the upper ecological protection layer, so that it is convenient to backfill planting soil in the protruding part of each ecological protection layer and plant suitable types of green plants, effectively improving the aesthetics of the bank protection structure.

[0007] In addition, in the present application, multiple ecological blocks are set in each ecological protection layer, and the ecological blocks are arranged adjacent to each other in sequence along the flow direction of the river, and an ecological containment structure connected to the water-facing side of the ecological block is set inside the ecological block. The ecological containment structure is used to provide growth and habitat space for aquatic organisms in the river, so that the riverbed bank protection structure has good ecology; and in the present application, when setting the ecological blocks, a horizontal connection part is set between the left and right adjacent ecological blocks in the same ecological protection layer. The horizontal connection part can be used to connect all the ecological blocks in the same ecological protection layer in the horizontal direction, and then a vertical connection part is set between the upper and lower adjacent ecological protection layers, so that the vertically adjacent ecological blocks form a connection relationship through the vertical connection part. Relying on the horizontal connection part and the vertical connection part, all the ecological blocks in the entire ecological retaining wall form a stable connection relationship after construction, effectively improving the structural strength of the entire ecological retaining wall, so that the ecological retaining wall has a more stable protection effect on the slope.

[0008] Preferably, as an improvement, the ecological containment structure includes a hollow portion arranged inside the ecological block, the hollow portion is connected to the top of the ecological block, a green plant planting trough connected to the hollow portion is provided on the water-facing side of the front side of the ecological block, and a filter element is provided between the green plant planting trough and the hollow portion.

[0009] In this solution, the hollow part is connected to the top of the ecological block. During the application process, planting soil and the like can be backfilled into the hollow part, and green plants can be planted using the planting soil backfilled in the hollow part. At the same time, a green plant planting trough connected to the hollow part is set on the water-facing side of the front side of the ecological block. Green plants can be planted in the green plant planting trough, and the planted green plants can be used to block the front side of the ecological block, thereby further improving the aesthetics of the bank protection structure. In addition, by setting a filter between the hollow part and the green plant planting trough, the filter can be used to prevent the loss of planting soil and the like in the hollow part, and at the same time, the green plants in the green plant planting trough can absorb nutrients from the planting soil in the hollow part. The structure is stable and can ensure the normal and stable growth of all green plants.

[0010] Preferably, as an improvement, the rear side of the ecological building block is provided with a rear side hole connected to the hollow part, and the rear side hole is connected to the anti-filtration structure; the two sides of the ecological building block are provided with side holes connected to the central hollow, and the side holes between the left and right adjacent ecological building blocks are connected to each other.

[0011] In this scheme, by setting side holes on the left and right sides of the ecological blocks, the ecological blocks in the same ecological protection layer are connected to each other in the horizontal direction, and then rear side holes are set on the rear side of the ecological blocks to facilitate water and soil exchange between the planting soil in the hollow part and the slope, as well as drainage of the slope.

[0012] Preferably, as an improvement, the filter element includes a three-dimensional soil and water conservation blanket fixedly connected to the inner wall of the hollow portion.

[0013] In this solution, the three-dimensional soil and water conservation blanket can be used to filter and protect the planting soil backfilled in the hollow part, effectively reducing soil and water loss.

[0014] Preferably, as an improvement, the transverse connecting portion includes a transverse slot and a transverse protrusion that are plugged into each other, the transverse slot is vertically arranged on the left or right side of the ecological building block, and the transverse protrusion is vertically arranged on the side of the ecological building block opposite to the transverse slot.

[0015] In this solution, the transverse protrusions and transverse slots are vertically arranged along the outer wall of the left or right side of the ecological building block. When the installation is completed, the transverse protrusions and transverse slots of adjacent ecological building blocks are plugged into each other. The plug-in relationship between the transverse protrusions and transverse slots is utilized to prevent the adjacent ecological building blocks on the left and right from moving horizontally at will. All ecological building blocks in the same ecological protection layer are connected together in the horizontal direction, effectively improving the structural stability of the ecological protection layer.

[0016] Preferably, as an improvement, the side wall of the transverse slot is inclined toward the inside of the ecological block, and the width of the side of the transverse protrusion away from the ecological block is greater than the side where the transverse protrusion is connected to the riverside protrusion; the number of the transverse protrusions is multiple, and the multiple transverse protrusions are arranged parallel to each other.

[0017] In this solution, the side walls of the transverse slots are tilted toward the inside of the eco-blocks, and correspondingly, the side walls of the transverse protrusions are also tilted, and the width of the transverse protrusions is larger on the side away from the eco-blocks. When installing adjacent eco-blocks, the transverse protrusions (or transverse slots) of the later-installed eco-blocks are aligned vertically with the transverse slots (or transverse protrusions) of the already-installed eco-blocks, and then the transverse protrusions of the later-installed eco-blocks are lowered and inserted into the transverse slots. After installation, the left and right adjacent eco-blocks will not separate from each other when subjected to transverse forces, thereby further improving the stability of the connection between the left and right adjacent eco-blocks.

[0018] Preferably, as an improvement, the vertical connection portion includes a vertical slot and a vertical plug post that can be plugged into each other, the vertical slot is arranged at the top of the ecological building block, and the vertical protrusion is arranged at the bottom of the ecological building block.

[0019] In this solution, a vertical slot is set at the top of the ecological block and a vertical protrusion is set at the bottom of the ecological block. When the ecological blocks of the upper and lower adjacent ecological protection layers are connected up and down, the vertical protrusion at the bottom of the ecological block in the upper ecological protection layer is inserted into the vertical slot at the top of the ecological block in the lower ecological protection layer, thereby forming a connection relationship between the upper and lower adjacent ecological protection layers, further improving the structural stability of the entire bank protection structure.

[0020] Preferably, as an improvement, there are multiple vertical slots and the multiple vertical slots are arranged along the length direction of the wide side of the top surface of the ecological building block.

[0021] In this solution, multiple vertical slots are set on the ecological building blocks, and an equal number of vertical protrusions are also set accordingly to further improve the stability of the connection between the upper and lower adjacent ecological building blocks, and multiple vertical slots are set along the length direction of the wide side of the top surface of the ecological building block, so that when the upper and lower ecological protection layer ecological blocks are connected, the upper layer of ecological building blocks can be moved a distance inward along the length of the wide side of the ecological building blocks toward the slope, so that the upper and lower ecological protection layers are arranged in a stepped manner; at the same time, by setting multiple vertical protrusions, during transportation, the multiple vertical protrusions can support and stabilize the ecological building blocks, so that multiple ecological building blocks can be neatly stacked and placed, making the transportation process more convenient and stable, and the vertical protrusions are not easily damaged during transportation.

[0022] Preferably, as an improvement, a connecting groove is provided on the front side wall of the ecological building block, the connecting groove is connected between the green plant planting groove and the hollow part, and a plurality of inclined baffles are arranged vertically in the connecting groove, a flow gap is provided between adjacent baffles, and the height of the bottom end of the upper baffle is lower than the height of the top end of the lower baffle.

[0023] In this solution, an inclined baffle is provided in the connecting groove, and the baffle can block the filter element to prevent the filter element from protruding out of the green plant planting groove due to the force of the planting soil in the hollow part, thereby protecting the filter element and effectively improving the service life of the filter element. In addition, since a flow gap is provided between adjacent baffles, and the height of the bottom end of the upper baffle is lower than the height of the top end of the lower baffle, when the water level in the river channel is located at the side position of the water-facing side of the ecological block in one of the ecological protection layers, the multiple baffles can reduce the impact of water surface waves on the filter element, thereby protecting the filter element, and when the water level of the river rises due to rain and other factors, the baffle structure can provide temporary protection for the green plants planted in the green plant planting groove.

[0024] Preferably, as an improvement, the filtration structure includes a filtration geotextile and a filtration gravel layer.

[0025] In this plan, by setting up anti-filtration geotextile and anti-filtration gravel layer, it can not only effectively reduce soil erosion on the slope, but also facilitate the installation and arrangement of ecological blocks, making construction more convenient.

[0034] The following is further described in detail through specific implementation methods:

[0035] The figure marks in the drawings of the specification include: slope 1, anti-filtration geotextile 2, anti-filtration gravel layer 3, ecological building block 4, horizontal slot 401, horizontal protrusion 402, vertical slot 403, vertical column 404, hollow part 405, green plant planting trough 406, side hole 407, rear side hole 408, connecting groove 409, three-dimensional soil and water conservation blanket 5, and baffle 6.

[0036] Example 1

[0037] This embodiment is as shown in the attached Figure 1 As shown: A riverbed bank protection structure includes an inclined slope 1, and a filtration mechanism and an ecological retaining wall are arranged outside the slope 1 from the inside to the outside. The filtration structure includes an filtration geotextile 2 and an filtration gravel layer 3. The filtration gravel layer 3 is preferably graded gravel. The ecological retaining wall includes multiple layers of ecological protection layers. The multiple layers of ecological protection layers are arranged along the inclined direction of the slope 1. The top surface of the lower ecological protection layer protrudes a certain distance from the bottom end of the upper ecological protection layer, so that it is convenient to backfill planting soil in the protruding part of each ecological protection layer and plant suitable types of green plants, thereby effectively improving the aesthetics of the bank protection structure.

[0038] Combine Figure 2 and Figure 4Each ecological protection layer includes multiple ecological building blocks 4. A horizontal connection portion is provided between adjacent ecological building blocks 4 within the same ecological protection layer, and a vertical connection portion is provided between two adjacent ecological protection layers. Specifically, the horizontal connection portion includes a horizontal slot 401 and a horizontal protrusion 402 that are plugged into each other. The horizontal slot 401 is vertically integrated on the left side of the ecological building block 4, and the horizontal protrusion 402 is vertically integrated on the right outer wall of the ecological building block 4. When the two ecological building blocks 4 are installed and placed on the left and right sides, the horizontal protrusion 402 on the left ecological building block 4 is inserted into the horizontal slot 401 of the right ecological building block 4, so that the left and right ecological building blocks 4 are connected.

[0039] Combine Figure 3 and Figure 5 The vertical connection part includes a vertical slot 403 and a vertical plug column 404 that can be plugged into each other. The vertical slot 403 is integrally formed at the top of the ecological building block 4, and the vertical protrusion is integrally formed at the bottom of the ecological building block 4. As for the shape of the vertical protrusion, it can be set to a cylindrical shape, or it can be set to other shapes such as a triangular cross-section, a quadrilateral cross-shape, etc.; at the same time, in order to improve the stability of the vertical connection between the upper and lower ecological building blocks 4, in this embodiment, the number of vertical slots 403 set on each ecological building block 4 is multiple, and the multiple vertical slots 403 are evenly divided into two groups and arranged at equal distances along the width direction of the top surface of the ecological building block 4.

[0040] Combine Figure 2 and Figure 3 , an ecological containment structure is provided in the ecological block 4 and is connected to the water-facing side of the ecological block 4. Specifically, the ecological containment structure includes a hollow portion 405 integrally formed inside the ecological block 4, the hollow portion 405 is connected to the top of the ecological block 4, and a green plant planting groove 406 connected to the hollow portion 405 is integrally formed on the water-facing side of the front side of the ecological block 4, and a filter is provided between the green plant planting groove 406 and the hollow portion 405. The filter in this embodiment is a three-dimensional soil and water conservation blanket 5, which is fixedly connected to the inner wall of the hollow portion 405 by screws; When the ecological building block 4 is in the process of being connected to the surface of the ecological building block 4, a side hole 407 connected to the hollow part 405 is formed on the left and right walls of the ecological building block 4, so that the hollow parts 405 of the ecological building blocks 4 adjacent on the left and right can be in a mutually connected state, and a rear hole 408 is formed on the rear side of the ecological building block 4, and the rear hole 408 is connected to the hollow part 405, so that the hollow part 405 can be connected to the anti-filtration gravel layer 3, so that the hollow part 405 can exchange water and soil with the slope 1 and assist the slope 1 in drainage. Specific implementation method:

[0042] In this embodiment, the anti-filtration geotextile 2 is first laid according to the inclination angle of the slope 1, and then the anti-filtration gravel layer 3 is laid on the anti-filtration geotextile 2. Finally, the installation and laying of multiple layers of ecological protection layer are completed in sequence from bottom to top. When laying the ecological blocks 4 in the same ecological protection layer, for the left and right adjacent ecological blocks 4, the horizontal protrusion 402 of the left ecological block 4 is inserted into the horizontal slot 401 of the right ecological block 4, so that the left and right adjacent ecological blocks 4 are connected to each other; then when installing the next layer of ecological protection layer, the ecological blocks 4 of the previous layer are moved a certain distance in the direction toward the inside of the slope 1. The moving distance can be an integer multiple of the distance of the vertical slot 403, so that a stepped structure is formed between the upper and lower layers of ecological protection layer.

[0043] After the riverbed bank protection structure is laid, backfill is carried out in the hollow part 405 of each ecological block 4. For the ecological blocks 4 below the normal water level, dog-head stones are backfilled in the hollow part 405. For the ecological blocks 4 above the normal water level, planting soil is backfilled in the hollow part 405. Green plants are planted in the protruding positions of the stepped structure and in the green plant planting grooves 406, which effectively improves the aesthetics.

[0044] Example 2

[0045] The difference between the second embodiment and the first embodiment is that: Figure 6 and Figure 7 In this embodiment, a connecting groove 409 is integrally formed on the front side wall of the ecological building block 4. The cross-sectional area of ​​the connecting groove 409 is smaller than the cross-sectional area of ​​the green plant planting groove 406. The connecting groove 409 is connected between the green plant planting groove 406 and the hollow portion 405, and a plurality of inclined baffles 6 are vertically arranged in the connecting groove 409. There is a flow gap between adjacent baffles 6, and the height of the bottom end of the upper baffle 6 is lower than the height of the top end of the lower baffle 6.

[0046] In this embodiment, by setting up multiple baffles 6 structures, the baffles 6 structures can protect the three-dimensional soil and water conservation blanket 5, reduce the impact of river water and other garbage in the river water directly on the three-dimensional soil and water conservation blanket 5, etc.; in addition, due to the setting of the three-dimensional soil and water conservation blanket 5, the green plants planted in the green plant planting trough 406 can grow more stably, etc.

[0047] Example 3

[0048] The difference between the third embodiment and the second embodiment is that: Figure 8As shown, in this embodiment, when the transverse slot 401 and the transverse protrusion 402 are set on the ecological building block 4, the side wall of the transverse slot 401 is inclined toward the inside of the ecological building block 4, so that an angle β is formed between the inner wall of the transverse slot 401 and the bottom wall of the transverse slot 401, β is less than 90°, preferably 75°; at the same time, the width of the side of the transverse protrusion 402 away from the ecological building block 4 is greater than the side where the transverse protrusion 402 is connected to the riverside protrusion, so that an angle α is formed between the side wall of the transverse protrusion 402 and the outer wall of the ecological building block 4, and α is equal to β.

[0049] In this embodiment, by tilting the sidewalls of the transverse slot 401 and correspondingly tilting the sidewalls of the transverse protrusion 402, after two adjacent eco-building blocks 4 are installed, the coordination between the tilted sidewalls of the transverse slot 401 and the transverse protrusion 402 prevents the two eco-building blocks 4 from moving relative to each other along the length of the eco-building block 4's width, nor from moving laterally along the length of the eco-building block 4's length, thereby further stabilizing the connection between all eco-building blocks 4 within the same ecological protection layer. Of course, due to the changes in the structure of the transverse slot 401 and the transverse protrusion 402 in this embodiment, the two eco-building blocks 4 cannot move laterally within the same horizontal plane to connect with each other during installation. The only way to successfully complete the installation process is to set a height difference between the eco-building blocks 4 installed in the vertical direction, then align the transverse protrusion 402 of the later-installed eco-building block 4 with the transverse slot 401 of the already installed eco-building block 4, and then lower the transverse protrusion 402 of the later-installed eco-building block 4 into the transverse slot 401.

[0050] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
