Abstract
Description
Technical Field
[0001] This utility model relates to the field of riverbank structure technology, specifically a riverbank structure that integrates pollution prevention and ecological greening. Background Technology
[0002] In recent years, with the rapid growth of the social economy, the overexploitation of mineral resources, the rapid expansion of industrial production, and the widespread use of chemical products in agricultural activities, a large number of toxic and harmful substances have been released into the soil and rivers. These harmful substances are frequently exchanged between soil, water, atmosphere, and organisms, and are absorbed by the human body through multiple pathways such as "soil-plant-human body", "soil-water-human body", "water-soil-human body", and "water-plant-human body", seriously threatening human health.
[0003] Among the sources of river pollution, industrial and domestic sewage discharge and polluted soil along the riverbanks are dominant. Faced with this challenge, river management is particularly important. By setting up riverbank structures that integrate ecological greening, the migration of pollutants in the river can be blocked.
[0004] For example, Chinese patent CN221956626U discloses an integrated riverbank structure, including: contaminated soil along the riverbank, a riverbed, and an ecological greening layer. This utility model relates to the field of riverbank technology and fully utilizes the natural purification capacity of the ecological greening layer. Metal-accumulating or hyperaccumulating plants absorb and enrich heavy metals and other harmful substances in the soil, reducing soil pollution. This method is not only low-cost but also environmentally friendly and conducive to maintaining ecological balance. The system, through the combination of a clay impermeable layer and an ecological gabion retaining wall, effectively prevents liquid from flowing from the inner side of the contaminated soil to the riverbed, preventing the spread of pollutants. Simultaneously, through lifting and pulling components and the siphon principle, it can efficiently divert and treat contaminated liquid, improving purification efficiency. The system utilizes mechanical structures such as lifting and pulling components and rotating discs to adjust the direction and speed of liquid diversion as needed to adapt to different pollution conditions and treatment requirements.
[0005] While the aforementioned patent effectively prevents the liquid inside the contaminated soil from flowing into the riverbed and prevents the spread of pollutants, the single-layer clay impermeable layer and the ecological gabion retaining wall used in the patent work together to block the contaminated soil along the riverbank from the riverbed. When the single-layer clay impermeable layer is damaged, the pollutants from the contaminated soil along the riverbank will migrate into the river channel, which can easily lead to incomplete river pollution control and poor results.

[0006] To address the shortcomings of existing technologies, this utility model provides a riverbank structure that integrates pollution mitigation and ecological greening. It features a double-layered clay impermeable layer and a double-layered ecological gabion retaining wall for impermeability, enhancing the stability of the barrier. This solves the problem that when a single-layered clay impermeable layer and ecological gabion retaining wall work together to isolate polluted soil from the riverbed, pollutants from the riverside soil can migrate into the river when the single-layered clay impermeable layer is damaged, leading to incomplete and ineffective river pollution control.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a riverbank structure that integrates pollution migration prevention and ecological greening, including a polluted soil layer along the riverbank and a riverbed, wherein a barrier mechanism is provided on the right side of the polluted soil layer along the riverbank, and a planting mechanism is provided on the right side of the barrier mechanism;
[0008] The barrier mechanism includes a first clay impermeable layer, a first ecological gabion retaining wall, a soil layer, a second clay impermeable layer, two second ecological gabion retaining walls, and ecological green plants.

[0016] Furthermore, the sliding block and the sliding rod are fitted with a gap, and the sliding block moves linearly up and down on the outside of the sliding rod.
[0017] By adopting this technical solution, when the water level in the riverbed rises, the sliding block can move upward on the outside of the sliding rod.
[0018] Furthermore, at least two of the planting pots are evenly distributed on the bottom wall of the inner cavity of the planting frame.
[0019] By adopting this technical solution, green plants can be evenly distributed and planted in planting pots.
[0020] Furthermore, the lower surface of the planting frame is provided with at least two flow holes, and each of the at least two flow holes is connected to the bottom of at least two planting pots.
[0021] By adopting this technical solution, water from the river can enter the interior of at least two planting pots through at least two flow holes.
[0022] Furthermore, the planting pot is a cone-shaped object that is hollow inside and lacks a top and bottom wall.
[0023] By adopting this technical solution, green plants can be planted inside planting pots, with the roots of the green plants located in the water of the riverbed.
[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1 This embodiment of a riverbank structure that integrates pollution mitigation and ecological greening includes a polluted soil layer 1 along the riverbank and a riverbed 2. A barrier mechanism 3 is provided on the right side of the polluted soil layer 1. The barrier mechanism 3 uses a double-layer clay impermeable layer and a double-layer ecological gabion retaining wall for barrier, which improves the stability of the barrier. A planting mechanism 4 is provided on the right side of the barrier mechanism 3. The planting mechanism 4 can purify the water in the riverbed 2 and beautify the river environment.
[0034] Please see Figure 2In order to improve the stability of the barrier by using a double-layer clay impermeable layer and a double-layer ecological gabion retaining wall, the barrier mechanism 3 in this embodiment includes a first clay impermeable layer 31, a first ecological gabion retaining wall 32, a soil layer 33, a second clay impermeable layer 34, two second ecological gabion retaining walls 35, and ecological green plants 36. The first clay impermeable layer 31 is set on the right side of the polluted soil layer 1 along the bank, the first ecological gabion retaining wall 32 is set on the right side of the first clay impermeable layer 31, the soil layer 33 is set on the right side of the first ecological gabion retaining wall 32, the second clay impermeable layer 34 is set on the right side of the soil layer 33, and both second ecological gabion retaining walls 35 are set on the right side of the second clay impermeable layer 34. The lower surface of the upper second ecological gabion retaining wall 35 is fixedly connected to the upper surface of the lower second ecological gabion retaining wall 35.
[0035] In this embodiment, the lower second ecological gabion retaining wall 35 is set on the left side of the riverbed 2, and the ecological green plants 36 are set on the upper surface of the polluted soil layer 1 along the bank. The first ecological gabion retaining wall 32 and the two second ecological gabion retaining walls 35 can block burrowing animals. The first ecological gabion retaining wall 32 and the two second ecological gabion retaining walls 35 can improve the stability of the structure of the first clay impermeable layer 31 and the second clay impermeable layer 34. The ecological green plants 36 can purify pollutants in the polluted soil along the bank, and the heavy metals and other harmful substances in the soil can be absorbed by metal-accumulating plants or hyperaccumulating plants.
[0036] In this embodiment, the ecological green plant 36 typically possesses a unique physiological mechanism that enables it to tolerate and accumulate high concentrations of heavy metals. The plant catalyzes the degradation of pollutants through enzymes secreted into the soil by its roots. These enzymes decompose organic pollutants, transforming them into harmless or low-toxicity substances. Furthermore, the plant can stimulate the proliferation of microorganisms by secreting low-molecular-weight organic compounds such as amino acids into the rhizosphere, indirectly promoting the rhizosphere microbial degradation of organic pollutants.
[0037] It should be noted that by setting up a first clay impermeable layer 31 and a first ecological gabion retaining wall 32 on the right side of the contaminated soil layer 1 along the riverbank, the contaminated soil layer 1 along the riverbank can be isolated from the riverbed 2, preventing liquid pollutants inside the contaminated soil layer 1 from flowing into the riverbed 2. When the first clay impermeable layer 31 is damaged by rats or other animals, it can be blocked again by the second clay impermeable layer 34. By setting up the first ecological gabion retaining wall 32, animals in the contaminated soil layer 1 along the riverbank can be prevented from burrowing into the interior of the second clay impermeable layer 34. By setting up two second ecological gabion retaining walls 35, the stability of the riverbank structure can be improved, the possibility of breaching the dike can be reduced, and thus the stability of the barrier can be improved.

The two support frames 41 are both set on the right side of the upper and lower second ecological gabion retaining walls 35, and the sliding rod 42 is fixed to the opposite side of the upper and lower support frames 41 by bolts.

The sliding block 43 and the sliding rod 42 are fitted with a gap. The planting frame 45 can be made of stainless steel, and the fixing rope 44 can deform.
[0040] In this embodiment, the sliding block 43 moves linearly up and down on the outside of the sliding rod 42. No fewer than two planting pots 47 are evenly distributed on the bottom wall of the inner cavity of the planting frame 45. No fewer than two flow holes are opened through the lower surface of the planting frame 45. No fewer than two flow holes are connected to the bottom of no fewer than two planting pots 47. The planting pot 47 is a cone-shaped body that is hollow inside and missing the top and bottom walls.
[0041] It should be noted that by planting green plants inside at least two planting pots 47, the water in the riverbed 2 can be purified. The planting frame 45 can be floated on the water surface by the floating ring 46. The bottom and top of the at least two planting pots 47 are open, and the roots of the green plants planted inside the planting pots 47 are located in the water in the riverbed 2.
[0042] The working principle of the above embodiments is as follows:
[0043] (1) By setting a first clay impermeable layer 31 and a first ecological gabion retaining wall 32 on the right side of the polluted soil layer 1 along the bank, the polluted soil layer 1 along the bank can be isolated from the riverbed 2, preventing liquid pollutants inside the polluted soil layer 1 from flowing into the riverbed 2. When the first clay impermeable layer 31 is damaged by rats or other animals, it can be blocked again by the second clay impermeable layer 34. By setting the first ecological gabion retaining wall 32, animals in the polluted soil layer 1 along the bank can be prevented from drilling into the interior of the second clay impermeable layer 34.
