[0040] The dam top area 300 has an inward side edge adjacent to the planting area 102, a water retaining wall 301 is protruded on the inward side edge, the lower part of the water retaining wall 301 is embedded in the dam 100, and the upper part of the water retaining wall 301 extends above the dam top area 300; the planting area 102 is planted with aquatic trees;

[0041] The inclined area 400 is formed by assembling a plurality of irregular-shaped concrete blocks 401, the lower part of the concrete block 401 is embedded in the dam 100, and the upper part of the concrete block 401 is exposed on the inclined area 400, an ecological area 402 for ecological habitat of fish is formed between adjacent concrete blocks 401, and the ecological area 402 is arranged in a recessed manner; along the direction away from the water-facing surface 101, the bottom area 500 is arranged in a downward inclined manner;

[0042] A plurality of flat stone bag 501 are fixed and stacked on the bottom area 500, the stone bag 501 comprises a steel wire mesh bag 502, a plurality of stone blocks 503 are arranged in the steel wire mesh bag 502; a bagged soil body 504 is mixed in the stone bag 501, and the bagged soil body 504 is mixed between the stone blocks 503; aquatic plants 505 are planted in the stone bag 501, and the root system of the aquatic plants 505 extends into the bagged soil body 504;

[0043] The platform is provided with a plurality of top-opened cylindrical grooves 201, and a rotatingly arranged cylinder 202 is arranged in the cylindrical groove 201, the lower part of the cylinder 202 is movably arranged in the cylindrical groove 201 to form a lower section 203, and the upper part of the cylinder 202 extends above the platform area 200 to form an upper section 204.

[0044] The multi-level ecological seawall provided has the following advantages:

[0045] 1) The dam 100 is sequentially provided with a dam top area 300, a planting area 102, a platform area 200, an inclined area 400 and a bottom area 500 from top to bottom, forming a rich hierarchical structure to provide diversified habitats for different organisms, and the water retaining wall 301 of the dam top area 300 not only plays a protective role, but also cooperates with the aquatic trees of the planting area 102 to enhance the ecological protection function and landscape effect of the seawall;

[0046] 2) The special-shaped concrete block 401 assembly structure of the inclined area 400 and the ecological area 402 therebetween provide a good habitat for aquatic organisms such as fish, increasing biodiversity, and the stone block bag 501 structure of the bottom area 500 mixed with bagged soil 504 and planted with aquatic plants 505 further expands the ecological space of the seawall, which is conducive to the growth of aquatic plants 505 and the reproduction of aquatic organisms, and also improves the stability and anti-erosion capacity of the seawall;

[0047] 3) The cylindrical groove 201 and the rotating cylinder 202 of the platform area 200 can make the wave energy more fully consumed in the platform area 200, and at the same time, the rotation of the cylinder 202 converts part of the impact force into rotational motion, further buffering the direct impact of the sea waves on the seawall, and the rotational motion also drives the nutrients in the sea waves to be more active, enhancing the ecological activity of the platform area 200 and improving the energy dissipation effect of the seawall.

[0048] In this embodiment, a central shaft 205 is protrudingly arranged in the cylindrical groove 201, the bottom of the central shaft 205 is fixed, the top of the central shaft 205 extends upward, the central shaft 205 movably penetrates the lower section 203, and the outer periphery of the lower section 203 and the inner side wall of the cylindrical groove 201 have a rotating gap 206, which is arranged around the outer periphery of the lower section 203.

[0049] In this way, the cylinder 202 can flexibly rotate around the central shaft 205, and when the water flow impacts the upper section 204, the cylinder 202 can rotate with it, thereby effectively reducing the water flow energy and reducing the erosion effect of the water flow on the seawall, enhancing the anti-erosion capacity of the seawall, helping to improve the stability of the seawall and prolong its service life.

[0050] In the embodiment, the bottom of the cylindrical groove 201 is provided with a plurality of rolling beads 207, which are arranged along the outer periphery of the central shaft 205 at intervals. The bottom of the cylindrical body 202 is movably abutted on the plurality of rolling beads 207.

[0051] The arrangement of the rolling beads 207 further reduces the frictional resistance when the cylindrical body 202 rotates, so that the cylindrical body 202 can rotate more smoothly under the impact of the water flow, improving the energy dissipation efficiency of the cylindrical body 202 to the water flow, and reducing the wear between the cylindrical body 202 and the cylindrical groove 201, which is beneficial to maintaining the integrity and durability of the seawall structure.

[0052] In the embodiment, a plurality of arc-shaped spiral holes 208 are arranged in the upper section 204 at intervals along the circumference of the upper section 204. The inner ends of the spiral holes 208 are arranged in the upper section 204, and the outer ends of the spiral holes 208 penetrate the outer periphery of the upper section 204, forming an outer periphery opening. During the impact of the water body on the upper section 204, the water body flows into the spiral holes 208, driving the cylindrical body 202 to rotate around the central shaft 205.

[0053] By using the spiral holes 208, the water flow can enter the spiral holes 208 and generate driving force when impacting the upper section 204, driving the cylindrical body 202 to rotate, further enhancing the energy dissipation effect of the seawall to the water flow, and also adding dynamic landscape effects to the seawall, improving the ornamental value of the seawall, so that the seawall not only has an ecological protection function, but also has a unique landscape value.

[0054] In the embodiment, the water retaining wall 301 has an inwardly arranged inward side wall, which is outwardly recessed in an arc shape. The inward side wall surrounds a water retaining area, which has an inwardly arranged inward opening 302. The lower part of the inward opening 302 is provided with a lower plate 303, which is arranged to close the lower part of the inward opening 302. The lower plate 303 is provided with an upper plate 304, which is arranged in the upper part of the inward opening 302.

[0055] The upper plate 304 includes a plurality of spaced apart grid bars 305, and adjacent grid bars 305 have grid holes 306 extending upward and downward. The water retaining area is in communication with the outside through the grid holes 306. When the water body carrying debris enters the water retaining area through the grid holes 306, the debris is blocked by the lower plate 303 and stays in the lower part of the water retaining area.

[0056] In this way, the entry of debris into the interior of the water retaining wall 301 is effectively prevented, avoiding the blockage and damage of the structure of the water retaining wall 301 and the internal facilities of the seawall. At the same time, the arc-shaped inward side wall can better guide the water flow, reduce the impact force of the water flow on the water retaining wall 301, and improve the flood control capacity and structural safety of the seawall.

[0057] In this embodiment, a plurality of drain holes 307 are arranged in the lower plate 303, and the water in the lower part of the water retaining area is drained outward through the plurality of drain holes 307.

[0058] The arrangement of the drain holes 307 ensures that the water in the water retaining area can be drained in time, avoiding excessive accumulation of water in the water retaining area, which can generate excessive pressure on the water retaining wall 301 and the seawall structure, further enhancing the stability and safety of the seawall, and facilitating the cleaning and maintenance of the water retaining area, keeping the seawall clean and in good operating condition.

[0059] In this embodiment, the lower part of the grid strip 305 is connected to the top of the lower plate 303, and the upper part of the grid strip 305 is arranged to bend towards the water retaining area; the top of the grid strip 305 is spaced apart from the top of the water retaining area, and the top of the grid strip 305 is bent towards the inside of the water retaining area to form a curved strip 308 arranged outwardly.

[0060] When the water carrying floating objects enters the water retaining area through the top spacing, the floating objects are blocked by the curved strip 308 and remain in the water retaining area.

[0061] By utilizing the shape characteristics of the curved strip 308, effective interception of floating objects is achieved, preventing floating objects from entering the interior of the seawall or being washed away to other areas by the water flow, reducing the pollution and damage caused by floating objects to the surrounding environment of the seawall and the marine ecosystem, and being conducive to maintaining the ecological environment around the seawall, thereby improving the ecological protection function of the seawall.

[0062] In this embodiment, an anchoring rod 403 is inserted into the ecological zone 402, the lower part of the anchoring rod 403 is embedded in the inclined zone 400 to form an integrated structure with the inclined zone 400, and the upper part of the anchoring rod 403 is exposed in the ecological zone 402; the anchoring rod 403 is sleeved with a movable mesh plate 404, the ecological zone 402 has an outwardly arranged outward opening, the mesh plate 404 covers the outward opening of the ecological zone 402, and the mesh plate 404 is provided with a plurality of mesh holes for fish to enter the ecological zone 402.

[0063] The arrangement of the anchoring rod 403 and the mesh plate 404 provides a safer and more stable habitat for aquatic organisms such as fish, the mesh holes facilitate the free entry and exit of fish into the ecological zone 402, increase the biodiversity of the ecological zone 402, and enhance the ecological restoration function of the seawall, promoting the balance and stability of the marine ecosystem, further enriching the ecological levels of the seawall, and embodying the important role of the multi-level ecological seawall in ecological protection.

[0064] In this embodiment, a plurality of steel wire strips extend inside the steel wire mesh bag 502, and the steel wire strips are sequentially wound around the outer periphery of the plurality of stone blocks 503, thereby combining the plurality of stone blocks 503 in the steel wire mesh bag 502 with the steel wire mesh bag 502 as a whole.

[0065] In this way, the winding structure of the steel wire enhances the connection strength between the steel mesh bag 502 and the stone 503, makes the whole stone bag 501 more stable, can better resist the erosion of water flow and the impact of sea waves, improves the stability of the sea embankment bottom area 500, and also provides a more solid base for the growth of aquatic plants 505, which is beneficial to the extension and fixation of the root system of aquatic plants 505, and further improves the ecological function and protection effect of the sea embankment.

[0066] In this embodiment, the stone 503 is provided with a plurality of groove holes 507, and the plurality of groove holes 507 are distributed on the outer surface of the stone 503, and the adjacent groove holes 507 are arranged at intervals.

[0067] In this way, the total mass area of the stone 503 is increased, providing more attachment space for microorganisms, algae and other organisms, which is beneficial to the formation and development of the biological community, further enriching the biodiversity of the sea embankment, and also enhancing the anti-erosion ability of the stone 503, because the water flow will produce a certain buffering and dispersion effect when passing through the groove hole 507, reducing the direct impact force of the water flow on the stone 503, improving the overall stability and ecological protection performance of the sea embankment.

[0068] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
