The sliding rods 19 on the two support frames are fixedly connected by pillars 30, allowing the two support frames to move synchronously. Several flexible biofillers 25 are evenly spaced between the connecting rods 24 on the two support frames. Aeration pipes are evenly distributed across the bottom of the treatment tank 4, connected to an external air pump to supply oxygen to the biofillers 25. The biofillers 25 are conventional bio-rope fillers, which are flexible and deformable. The bio-rope is equipped with hard filaments that can cut bubbles in the water, allowing the gas contained in the bubbles to be fully released into the water.

[0031] A lifting structure for driving the slide bar 19 to rise and fall is provided in the processing box 4. The lifting structure includes a first rotating shaft 26, which is arranged perpendicular to the slide bar 19. The two ends of the first rotating shaft 26 are respectively connected to the inner wall of the processing box 4 through bearings for rotation. A motor for driving the first rotating shaft 26 to rotate is fixedly provided inside the processing box 4. Two lifting units are provided on the first rotating shaft 26, and the lifting units include two oppositely arranged turntables 27, which are fixedly connected only by an eccentric rod 29. A transmission rod 28 is sleeved on the eccentric rod 29, and the transmission rod 28 is connected to the eccentric rod 29 for rotation. The bottom end of the transmission rod 28 is hinged to the slide bar 19. Rollers 20 are rotatably provided at both ends of the slide bar 19, and a guide rail 21 is provided on the inner wall of the processing box 4 for guiding the sliding of the slide bar 19. The roller 20 is located in the guide rail 21 and slides along the guide rail 21.

[0032] The interior of the processing box 4 is provided with a sliding structure that drives the support rod 23 to slide horizontally. The sliding structure includes a second rotating shaft 32, which is arranged parallel to the first rotating shaft 26 and is rotatably connected to the slide rod 19 via a bearing. A gear is fixed to the end of the second rotating shaft 32, which meshes with a rack 31 fixed to the side wall of the processing box 4. A cam 33 is fixed to the second rotating shaft 32, and the cam 33 contacts a push plate 34 fixed to the support rod 23. A plurality of guide posts 35 are evenly fixed to the support rod 23 at the end of the slide rod 19 away from the cam 33. Springs 36 are provided on the outside of the guide posts 35, and the ends of the springs 36 are respectively connected to the support rod 23 and the baffle. The ends of the baffle are fixedly connected to the slide rod 19. The push plate 34 is always in contact with the side wall of the cam 33 under the action of the spring 36.

[0033] The motor drives the first rotating shaft 26 to rotate, which in turn drives the turntable 27. The turntable 27 drives the slide bar 19 up and down via the eccentric rod 29 and transmission rod 28. The slide bar 19 drives the support rod 23 to slide up and down synchronously via the sleeve 22. The support rod 23 drives the bio-filler 25 to slide up and down synchronously via the connecting rod 24. The slide bar 19 drives the second rotating shaft 32 to move up and down synchronously. The gear on the second rotating shaft 32 rotates under the action of the rack 31. This gear drives the second rotating shaft 32 to rotate, which in turn drives the cam 33. The cam 33 pushes the support rod 23 to slide horizontally along the slide bar 19 via the push plate 34. The support rod 23 drives the bio-filler 25 to slide horizontally via the connecting rod 24. The bio-filler 25 undergoes a combined horizontal and vertical motion within the treatment chamber 4, facilitating full contact between the bio-filler 25 and the water, cutting bubbles and allowing for sufficient oxygen release, thereby enhancing the bio-filler 25's water treatment effectiveness.

[0034] The above-mentioned construction method of the riverbank ecological restoration revetment includes the following steps: S1. Compact the soil layer on the slope 1, and excavate a trough at the bottom of the slope 1 to place the treatment box 4. The treatment box 4 can be a cast-in-place reinforced concrete structure or a prefabricated reinforced concrete box.

[0035] S2. Excavate a planting platform on one side of the top of the processing box 4, and the planting platform is flush with the top of the processing box 4. Place the planting frame 2 on the planting platform, with one side of the planting frame 2 placed on the top of the processing box 4, and the second water outlet 15 is located directly above the second water inlet 18.

[0036] S3. Dig a planting platform on one side of the top of the planting frame 2, and the planting platform is flush with the top of the planting frame 2. Place the planting frame 2 on the planting platform, with one side of the upper planting frame 2 placed on the top of the lower planting frame 2, and the second water outlet 15 is located directly above the first water inlet 11, and the laying of the planting frame 2 is completed in sequence.

[0037] S4. Excavate a platform on top of the topmost planting frame 2 and place the water reservoir 3 on the platform, with the first water outlet 5 of the water reservoir 3 located directly above the first water inlet 11. Fill the water reservoir 3 with an activated carbon layer 9, a first filter sand 8, and a filter screen 7, and cover it with a grid plate 6.

[0038] S5. Fill the planting frame 2 with the second filter sand 17 and the planting soil 16 and lay permeable bricks to plant vegetation.

[0039] S6. Set up a water treatment structure inside the treatment box 4, cover the top of the treatment box 4 with a cover 37, lay pipelines, and complete the revetment construction.

[0040] During use, water from the river is introduced into the reservoir 3 through the water inlet via a water pump and water pipe. After being treated by the filter screen 7, the first filter sand 8, and the activated carbon layer 9, the water enters the planting frame 2 through the first water outlet 5 and the first water inlet 11. After being filtered by the second filter sand 17 in the planting frame 2, the water enters the planting frame 2 below through the second water outlet 15 and the first water inlet 11. The water in the bottom planting frame 2 enters the treatment box 4 through the second water outlet 15 and the second water inlet 18, where it is treated. The treated water is returned to the river through the water pump and water pipe, completing the treatment of the water in the river. Rainwater seeps downward through the permeable bricks, planting soil 16, and the second filter sand 17, and then flows into the treatment box 4 for treatment.

[0041] Therefore, the use of a riverbank ecological restoration revetment and construction method described in the present invention can solve the problem that the existing ecological revetment vegetation has poor stability and is prone to river pollution.
