Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to an eco-friendly revetment structure. Background Technology

[0002] Rivers are the main channels for flood discharge during the flood season, characterized by high flow velocity and high water levels. In areas with high flow velocity, ecological block revetments are often used to meet the requirements of erosion resistance and ecology during the flood season. These revetments are characterized by simple construction, stable root systems for plant growth, and good greening effects.

[0003] However, existing ecological blocks only connect to the water body through small holes in the blocks themselves or seams between blocks, which cannot truly achieve shore-water connectivity, meet the requirements of amphibious activities, lack biomimetic characteristics, and ultimately affect the waterfront ecological environment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an eco-friendly revetment structure to address the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: an eco-friendly revetment structure, comprising:

[0006] The foundation blocks, with at least part of their bottom buried in the riverbed, are arranged along the embankment to provide bottom support and installation foundations;

[0007] The first connector is located between adjacent base blocks and is used to connect the adjacent base blocks.

[0008] The ecological space block is installed on top of the base block and has a habitat chamber inside. Fish slits are provided on the water-facing side wall to connect the habitat chambers, so that the adjacent ecological space blocks form a passage for reptiles on the riverbed to enter the habitat chambers. The water-facing side wall of the ecological space block has a group of fish holes to connect the habitat chambers, and adjacent ecological space blocks can be spliced ​​together.

[0009] The second connector is located on the side wall of the embankment of the ecological space block and is used to fix the ecological space block to the embankment.

[0010] By employing the aforementioned technical methods, and by incorporating fish slits and fish holes on the waterfront sidewalls of the ecological space blocks, connectivity between the water flow and the habitat chambers can be achieved, promoting water exchange and benefiting the activities of fish and amphibians, thereby enhancing shore-water connectivity. The inclusion of habitat chambers within the design provides a safe habitat for small aquatic organisms and reptiles, contributing to increased biodiversity.

[0011] In some embodiments, the ecological space block has a "C" shaped structure, with a snap-fit ​​groove on one side and a snap-fit ​​protrusion on the other side. The snap-fit ​​groove and the snap-fit ​​protrusion can snap together, allowing adjacent ecological space blocks to be snapped together and assembled.

[0012] In some embodiments, the first connector includes a first connecting rod, and holes are provided through both sides of the bottom of the base block. The first connecting rod is inserted into the holes, and adjacent base blocks can be connected by the first connecting rod.

[0013] In some embodiments, the second connector includes a second connecting rod, which has a "T" shaped structure. One end of the second connecting rod is connected to the side wall of the ecological space block facing the embankment, and the other end is buried inside the embankment. Multiple second connecting rods are arranged at intervals along the vertical direction.

[0014] In some embodiments, the number n of the second connecting rods is set according to the slope height, specifically obtained by rounding the result of the formula: n = slope height / 1.5.

[0015] In some embodiments, the fish hole group includes a first fish hole, a second fish hole, and a third fish hole, which are arranged at intervals in a vertical direction. The positions of the first fish hole, the second fish hole, and the third fish hole correspond to the low water level, normal water level, and flood level of the river, respectively.

[0016] In some embodiments, the top of the base block is provided with a mounting groove, the width of which is adapted to the bottom width of the ecological space block, so that the ecological space block can be installed into the mounting groove.

[0017] In some embodiments, the depth to which the foundation block is buried in the riverbed is not less than 1.5 times the theoretically calculated maximum scour depth.

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

[0019] 1. By burying the bottom of the foundation blocks into the riverbed and connecting adjacent foundation blocks using the first connector, the stability of the entire revetment structure is ensured, enabling it to withstand the impact of high-velocity flows. 2. By incorporating habitat chambers within the ecological space blocks and setting up fish crevices and fish holes on the water-facing side walls of the ecological space blocks, the external water flow is connected to the water flow inside the habitat chambers, promoting water exchange. This not only provides a safe habitat for small aquatic organisms and reptiles but also helps improve biodiversity, thereby enhancing the connectivity between the shore and water.

[0020] 2. This structure features modularity, allowing components to be prefabricated off-site and then transported to the site for installation, minimizing the impact of construction on the surrounding ecological environment. The first connector links adjacent foundation blocks, ensuring the stability of the entire revetment structure and enabling it to withstand the impact of high-velocity flows. The second connector reinforces the connection between the ecological space blocks and the embankment, ensuring greater stability of the entire revetment structure against external forces such as water flow impacts, reducing the risk of displacement or damage caused by water erosion. Furthermore, the design for splicing between ecological space blocks facilitates not only installation but also subsequent maintenance and adjustments. Attached Figure Description

Specific features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

[0027] The term "comprising" is open-ended. As used in the appended claims, it does not exclude additional structures or steps.

[0028] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation

[0029] 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.

[0030] Combination Figures 1 to 3 As shown, this embodiment is an eco-friendly revetment structure, including a base block 300, a first connector, an ecological space block 400, and a second connector. The base block 300 is at least partially buried in the riverbed. Adjacent base blocks 300 are connected by the first connector, allowing multiple base blocks 300 to be arranged along the embankment line 200. The base blocks 300 provide bottom support and installation foundation for the ecological space blocks 400. The ecological space blocks 400 are installed on top of the base blocks 300 and have habitat chambers 480 inside. The ecological space blocks 400 have fish slits 490 on their water-facing sidewalls 440, connecting to the habitat chambers 480, thus creating passageways between adjacent ecological space blocks 400 for reptiles from the riverbed to enter the habitat chambers 480. The water-facing sidewalls 440 of the ecological space blocks 400 also have a group of fish holes connecting to the habitat chambers 480. Adjacent ecological space blocks 400 can be spliced ​​together. A second connector is provided on the embankment sidewall 410 of the ecological space block 400, which is used to fix the ecological space block 400 to the embankment 200.

[0031] In some implementation schemes, such as Figure 3 As shown, the ecological space block 400 has a "C" shaped structure. One side of the ecological space block 400 is provided with a snap-fit ​​groove 430, and the other side of the ecological space block 400 is provided with a snap-fit ​​protrusion 420. The snap-fit ​​groove 430 and the snap-fit ​​protrusion 420 can snap together, so that adjacent ecological space blocks 400 can be snapped together and assembled.

[0032] The snap-fit ​​design simplifies the construction process. The snap-fit ​​assembly ensures a tight connection between adjacent ecological space blocks (400mm), reducing the risk of loosening or misalignment due to water flow impact and improving the overall stability of the revetment structure. The modular snap-fit ​​design facilitates subsequent expansion or partial replacement, adapting to the needs of different river sections.

[0033] In some implementations, the first connector includes a first connecting rod 330, and holes 320 are provided through the bottom sides of the base block 300. The first connecting rod 330 is inserted into the holes 320, and adjacent base blocks 300 can be connected through the first connecting rod 330.

[0034] The first connecting rod 330 is inserted into the holes 320 on both sides of the bottom of the foundation block 300 to connect adjacent foundation blocks 300. The first connecting rod 330 enhances the lateral connection between adjacent foundation blocks 300, preventing separation of the foundation blocks 300 due to water erosion or geological changes. The plug-in connection method facilitates on-site construction operations, and the number and position of the connecting rods can be adjusted according to actual conditions to adapt to different engineering needs. By strengthening the connection between the foundation blocks 300, the entire revetment structure is more stable and can better resist high-velocity water flow during flood season.

[0035] In some embodiments, the second connector includes a second connecting rod 401, which has a "T"-shaped structure. One end of the second connecting rod 401 is connected to the side wall 410 of the ecological space block 400 facing the embankment 200, and the other end is embedded inside the embankment 200. Multiple second connecting rods 401 are arranged at intervals along the vertical direction. Specifically, the T-shaped end of the second connecting rod 401 is embedded inside the embankment 200.

[0036] Furthermore, the number n of the second connecting rods 401 is set according to the slope height. The specific number n is obtained by rounding the result of the formula calculation: n = slope height (m) / 1.5.

[0037] The T-shaped structure provides a larger contact area, effectively preventing the ecological space block 400 from shifting due to water flow impact. Multiple second connecting rods 401 can evenly distribute the force, avoiding localized stress concentration and improving the overall structural durability.

[0038] In some implementation schemes, such as Figure 2 As shown, the fish hole group includes a first fish hole 450, a second fish hole 460, and a third fish hole 470. The first fish hole 450, the second fish hole 460, and the third fish hole 470 are arranged at intervals in the vertical direction. The first fish hole 450, the second fish hole 460, and the third fish hole 470 are located at different elevations. The center elevations of the first fish hole 450, the second fish hole 460, and the third fish hole 470 correspond to the low water level, normal water level, and flood level of the river 100, respectively, thereby ensuring that fish can enter and exit the habitat space inside the ecological space block 400 in different seasons, even if the water level changes.

[0039] The layered arrangement of fish holes not only meets the passage needs of fish and other aquatic organisms at different water levels and promotes biodiversity, but also dynamically adapts to changes in river water level, ensuring that the biological passage remains unobstructed regardless of whether it is the dry season or the flood season.

[0040] In some implementation schemes, such as Figure 2 As shown, the base block 300 has a mounting groove 310 on its top. The width of the mounting groove 310 is adapted to the bottom width of the ecological space block 400, so that the ecological space block 400 can be installed into the mounting groove 310.

[0041] In some implementation schemes, the foundation block 300 is buried in the riverbed to a depth of not less than 1.5 times the theoretically calculated maximum scour depth.

[0042] The implementation principle of an eco-friendly revetment structure is as follows:

[0043] Through snap-fit ​​assembly, connecting rod design, and optimized 300mm burial depth of the foundation block, the erosion resistance and overall stability of the revetment structure are significantly improved. The ecological space block 400 incorporates habitat chambers 480 that can serve as fish habitats, promoting shore-water connectivity, supporting the survival of amphibians and aquatic organisms, and enhancing biodiversity in the waterfront area. The layered arrangement of fish holes and the inclusion of fish slits 490 adapt to different seasons and water level changes, providing habitat for aquatic life.

[0044] 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.
