Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to an ecological bank protection structure. Background Technology

[0002] On the one hand, traditional rigid revetment materials are mostly made of concrete. Although they can effectively prevent riverbank erosion, they lack ecological functions and may cause localized damage under the impact of strong water flows. Especially during floods or rainstorms, the water flow speed increases, increasing the erosion and impact on the riverbank.

[0003] On the other hand, traditional bank protection structures neglect the protection of the original ecological environment, leading to a reduction in aquatic habitats and affecting the reproduction and survival of fish and other aquatic organisms. Furthermore, the lack of suitable spaces for fish and other aquatic organisms to inhabit, forage, and reproduce is detrimental to maintaining the health and diversity of the river ecosystem.

[0004] Therefore, an ecological revetment structure is needed that can both ensure erosion resistance and provide habitats for aquatic animals to improve the ecological protection effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an ecological bank protection structure to address the above-mentioned problems.

[0006] The technical solution adopted in this utility model is: an ecological bank protection structure, comprising:

[0007] Fish nest blocks are located on the riverbed at the foot of the slope. The top of the inner part has a first cavity for fish to inhabit. The side wall facing the water has at least a partial channel that can connect to the first cavity. Multiple fish nest blocks are arranged along the extension direction of the slope foot to form a supporting base for the bank protection structure.

[0008] Ecological blocks are placed on top of fish nest blocks. The top of the inner part has a second cavity for filling soil, and the bottom of the inner part has multiple through holes that connect to the second cavity. Multiple ecological blocks are stacked on the slope surface.

[0009] Connectors are provided between adjacent fish nest blocks, adjacent ecological blocks, and between adjacent fish nest blocks and ecological blocks, so that fish nest blocks and ecological blocks can be horizontally adjacent or vertically stacked.

[0010] Through the aforementioned technical means, fish nest blocks can be spliced ​​together using connectors to form the supporting structure of the revetment, enhancing the foundation stability of the riverbank. The channels set on the fish nest blocks facilitate fish swimming into the first cavity, which can serve as a habitat for fish, thus creating an ecological environment conducive to the survival and development of aquatic organisms. Furthermore, this structure can effectively disperse some of the water flow energy, reducing the impact on the revetment structure. Using connectors, ecological blocks can be spliced ​​together to form the main structure of the revetment, while the second cavity can serve as a space for vegetation growth, helping to stabilize the riverbank soil. Thus, the combination of these two elements helps maintain the health and diversity of the river ecosystem.

[0011] In some embodiments, the connector is an "H"-shaped pin structure, and the connector includes a horizontal rod and an insertion rod. The two ends of the horizontal rod are respectively vertically connected to the insertion rod, and the end of the horizontal rod is connected to the middle of the insertion rod.

[0012] Both the fish nest block and the ecological block have multiple pin holes running vertically through them. These pin holes are located on both sides of the first cavity or the second cavity and are arranged symmetrically. The pin holes can be inserted into the insertion rod. The top of both the fish nest block and the ecological block has multiple pin grooves running horizontally. These pin grooves are parallel to each other and communicate with the top of the pin holes. The pin grooves at the top of the symmetrical pin holes are located on the same axis, so that when the insertion rod is inserted into the pin hole, the horizontal rod can be embedded in the corresponding pin groove.

[0013] In some embodiments, the top of the pin hole is provided with a funnel-shaped opening.

[0014] In some embodiments, the total length of the insertion rod corresponds to the depth of the pin hole.

[0015] In some embodiments, the fish nest blocks and the ecological blocks have a curved structure on their surfaces, so that when adjacent fish nest blocks or ecological blocks are spliced ​​together, a first curved notch or a second curved notch is formed at the joint, and both the first curved notch and the second curved notch can be easily filled with porous pebbles.

[0016] In some embodiments, the sidewall of the fish nest block is provided with a blocking part located at the bottom of the channel, and the vertical height of the blocking part is 1 / 3 of the vertical height of the fish nest block.

[0017] In some embodiments, the arrangement of the fish nest blocks, the ecological blocks, and the fish nest blocks and ecological blocks can be either horizontally adjacent and sequentially connected, vertically adjacent and sequentially stacked, or vertically staggered and stacked.

[0018] The beneficial effects of this utility model are:

[0019] 1. By placing fish nest blocks on the riverbed at the toe of the slope, the structure enhances the foundation stability of the riverbank, helping to resist water erosion. The cavities inside the fish nest blocks provide ideal habitats and breeding spaces for fish and other aquatic organisms, offering a safe habitat. The passages on the upper sidewalls of the fish nest blocks not only ensure free access for these organisms, increasing habitat accessibility and safety, but also help disperse water flow energy, reducing direct impact force, thereby improving the erosion resistance of the entire revetment structure. The cavities within the ecological blocks can be filled with soil for planting vegetation, which not only helps beautify the environment and is beneficial to the survival and reproduction of organisms, but also further stabilizes the riverbank soil and improves the overall stability of the revetment structure.

[0020] 2. By using connectors, fish nest blocks and ecological blocks can be spliced ​​both horizontally and vertically, greatly improving the flexibility of the entire revetment structure and its ability to adapt to different terrain changes. This also simplifies the construction process and reduces costs. The H-shaped connectors can simultaneously secure four fish nest blocks or ecological blocks in the vertical and horizontal positions, increasing the overall structural stability. The stacking of multiple layers of fish nest blocks also allows for adaptation to changes in river water levels, consistently providing habitat for aquatic animals. Attached Figure Description

[0036] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0037] Example 1:

[0038] Combination Figures 1 to 10As shown, this embodiment is an ecological revetment structure, including a fish nest block 41, an ecological block 31, and a connector 35. The fish nest block 41 is located on the riverbed at the toe of the slope. The inner top of the fish nest block 41 has a first cavity 42 for fish to inhabit. The side wall facing the water has at least a partial channel 42a that connects to the first cavity 42, allowing fish to enter the first cavity 42 through the channel 42a. The top of the fish nest block 41 has an ecological block 31. The inner top of the ecological block 31 has a second cavity 32 for filling with soil. The inner bottom has multiple through holes that connect to the second cavity 32. After the second cavity 32 is filled with soil, vegetation 52 can be planted. The roots of the vegetation 52 can take root in the soil 50 of the bottom slope through the through holes at the bottom. Connectors 35 are provided between adjacent fish nest blocks 41, adjacent ecological blocks 31, and between adjacent fish nest blocks 41 and ecological blocks 31. Connectors 35 are used to splice fish nest blocks 41 or ecological blocks 31, so that fish nest blocks 41 and ecological blocks 31 can be spliced ​​together horizontally or stacked vertically. Multiple fish nest blocks 41 are connected by connectors 35 and arranged along the slope toe to form the supporting base of the revetment structure. Multiple ecological blocks 31 are installed on top of fish nest blocks 41 by connectors 35 and stacked on top of each other on the slope surface to form the main part of the revetment structure.

[0039] In some implementation schemes, such as Figure 1 and Figure 5 As shown, in this embodiment, the connector 35 has an "H" shaped pin structure. The connector 35 includes a horizontal rod 35b and an insertion rod 35a. The two ends of the horizontal rod 35b are respectively vertically connected to the insertion rod 35a, and the end of the horizontal rod 35b is correspondingly connected to the middle position of the insertion rod 35a.

[0040] Furthermore, such as Figures 1 to 8 As shown, both the fish nest block 41 and the ecological block 31 have multiple vertically penetrating pin holes 34. These pin holes 34 are located on both sides of the first cavity 42 or the second cavity 32 and are arranged symmetrically. The pin holes 34 can be inserted into the insertion rod 35a. Both the fish nest block 41 and the ecological block 31 have multiple horizontally arranged pin grooves 33 at their tops. These grooves are parallel to each other and communicate with the tops of the pin holes 34. The top pin grooves 33 of the symmetrical pin holes 34 are located on the same axis, so that when the insertion rod 35a is inserted into the pin hole 34, the horizontal rod 35b can be embedded in the corresponding pin groove 33. Specifically, in this embodiment, the fish nest block 41 or the ecological block 31 has three sets of symmetrical pin holes 34.

[0041] By employing an H-shaped pin structure connector 35, the insertion rods 35a at both ends are inserted into the pin holes 34 to ensure vertical fixation, while the horizontal rod 35b in the middle is embedded in the pin groove 33, increasing the overall structural stability and tensile strength. This ensures a secure connection between the fish nest block 41 and the ecological block 31, as well as between them. This connection method not only simplifies the construction process but also improves the durability of the entire revetment structure.

[0042] Furthermore, the top of the pin hole 34 is provided with a funnel-shaped opening 34a.

[0043] The funnel-shaped opening 34a at the top of the pin hole 34 makes it easier and more accurate to insert the insertion rod 35a into the pin hole 34, improving installation efficiency and accuracy, and also facilitating disassembly during later maintenance.

[0044] Furthermore, the insertion depth of the insertion rod 35a is half the height of the ecological block 31 or the fish nest block 41. That is, the total length of the insertion rod 35a corresponds to the depth of the pin hole 34, ensuring that the insertion rod 35a can be fully inserted into the pin hole 34, providing sufficient support and stability, and avoiding structural loosening or failure due to insufficient insertion.

[0045] In some implementation schemes, the fish nest block 41 and the ecological block 31 have a curved structure, so that when adjacent fish nest blocks 41 or ecological blocks 31 are spliced ​​together, a first curved notch 46 or a second curved notch 36 is formed at the joint. Both the first curved notch 46 and the second curved notch 36 can be easily filled with porous pebbles 51, which can not only enhance the friction between the structures and improve the overall stability, but also provide more hidden habitat space for aquatic organisms, which is conducive to the construction of the ecological environment, and also provide more growth space for plants, softening the hard revetment structure.

[0046] In some embodiments, the sidewall of the fish nest block 41 is provided with a blocking portion 42b located at the bottom of the channel 42a, and the vertical height of the blocking portion 42b is approximately 1 / 3 of the vertical height of the fish nest block 41. The structural design of the blocking portion 42b can reduce the entry of riverbed sediment into the first cavity 42 and form silt, and is also beneficial to the stability of the fish nest block 41 structure.

[0047] In some implementation schemes, such as Figure 9 and Figure 10As shown, the arrangement of fish nest blocks 41, ecological blocks 31, and fish nest blocks 41 and ecological blocks 31 can be either horizontally adjacent, vertically adjacent, or vertically staggered. Since adjacent blocks are fixed using connectors 35 with an "H"-shaped pin structure, four blocks can be fixed simultaneously (top, bottom, left, and right), ensuring stable stacking under any circumstances. The staggered stacking method facilitates the formation of a triangular structure, increasing overall structural stability. These multiple arrangement methods greatly enhance the structure's flexibility and adaptability, allowing it to better adapt to different terrain conditions and water flow, while also improving the overall structural stability and aesthetics.

[0048] The implementation principle of an ecological bank protection structure is as follows:

[0049] like Figure 10 As shown, by installing multiple fish nest blocks 41 on the riverbed at the toe of the slope, and connecting and fixing the horizontally adjacent and vertically stacked fish nest blocks 41 using connectors 35, the fish nest blocks 41 form the supporting foundation of the bank protection structure, providing good stability and erosion resistance for the bank protection. The protrusions on the water-facing side of the multiple fish nest blocks 41 can effectively disperse the incoming flow and reduce the direct impact force. When the water flow comes into contact with these protrusions, turbulence and small eddies are formed, which helps to disperse the energy of the water flow rather than concentrate it on a certain point, thereby reducing the erosion pressure on a single point. At the same time, the water-facing channel allows a certain degree of water flow, but also slows down the water flow velocity, enhancing the erosion resistance. The first cavity 42 inside the fish nest block 41 forms a habitat space for aquatic organisms. The multiple fish nest blocks 41 in the vertical direction make the channel 42a arranged in multiple levels, which can adapt to changes in the water level in the river channel and always provide habitat space for aquatic animals.

[0050] The top of the fish nest block 41 is connected to an ecological block 31 via a connector 35. The ecological blocks 31 are stacked alternately along the slope surface. Porous pebbles 51 are filled into the first curved recess 46 formed between the fish nest blocks 41 and the second curved recess 36 formed between the ecological blocks 31. These porous pebbles 51 fill the gaps between the slope soil 50 and the revetment structure, enhancing the friction between the structures and acting as a filter layer. Planting soil is then filled into the second cavity 32 of the ecological block 31, and vegetation 52 is planted. The roots of the vegetation 52 extend into the slope soil 50 through the bottom openings. The interaction between the vegetation roots and the slope soil 50 increases soil retention capacity and reduces erosion. Simultaneously, the presence of vegetation 52 provides food and habitat for small organisms, contributing to increased biodiversity of the entire ecosystem.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
