Problems solved by technology

However, the dredged sediment often contains a large amount of toxic heavy metals and other organic pollutants, and a large amount of land is required for storage. Moreover, rainfall and surface erosion will cause the pollutants in the sediment to infiltrate or laterally seep with the runoff, causing serious damage to the water environment. Secondary pollution
In the process of transportation, the sediment is also easy to pollute the environment, and the freight is high

Embodiment 1

[0029] The present invention provides an ecological bank revetment structure, which includes an adsorption filter layer 3 and a bottom mud ecological bag layer 4 arranged from bottom to top along a bank revetment foundation slope 1 . The vertical height of the bottom mud ecological bag layer 4 and the adsorption filter layer 3 can be adjusted according to the revetment height. Preferably, the vertical height ratio of the bottom mud ecological bag layer to the adsorption filter layer can be set to 1:1˜3:2.

[0030] The bottom mud ecological bag layer 4 is formed by stacking ecological bags 5 filled with bottom mud and fine sand. Plants 6 are planted on the ecological bag 5, and the plants 6 are heavy metal super-accumulating plants and other landscape plants. The bottom mud ecological bag layer 4 adopts water-permeable and soil-impermeable environment-friendly ecological bags 5, which are connected together by a tight locking structure, and form a flexible and stable revetment ...

Embodiment 2

[0038] The present invention also provides a kind of ecological revetment method, described revetment method comprises the steps:

[0039] A. Conduct harmless treatment of the dredged sediment of rivers and lakes, crush the treated sediment and mix it with fine sand for later use. Specifically, after the river and lake dredging sediment is dehydrated and reduced on the spot, heavy metal chelating agents, curing agents, and microorganisms that can degrade heavy metal pollution are added to carry out harmless treatment of heavy metals and other pollutants in the sediment, and finally Crush the treated bottom mud and mix it with fine sand in a volume ratio of 1:1 to 2:1 for later use.

[0040] B. Treat the revetment foundation slope 1 according to the height and slope required by the revetment design to meet the construction requirements.

[0041] C. Lay graded gravel, zeolite and fly ash on the revetment foundation slope 1 to form an adsorption filter layer 3, and lay a three-dim...

Abstract

The invention relates to an ecological bank protection structure and an ecological bank protection method. The ecological bank protection structure comprises an adsorption filter layer and an ecological bottom sediment bag layer which are arranged along a bank protection base slope from bottom to top, wherein the adsorption filter layer is of a layered structure formed by paving graded gravel, zeolite and fly ash; a three-dimensional plant net is further paved above the adsorption filter layer; the ecological bottom sediment bag layer is formed by piling ecological bags internally filled with bottom sediment and fine sand; plants are planted on the ecological bags. According to the ecological bank protection structure and the ecological bank protection method, the bottom sediment obtained after de-silting rivers and lakes is utilized in place, pollutants and eutrophication materials of the bottom sediment are further absorbed and filtered through a layered bank protection structure and vegetation plantation, harmless resource utilization of the bottom sediment is achieved, waste of resources such as planting soil needed by bank protection construction is avoided, the transporting cost of the bottom sediment is reduced, and an ecological bank protector which is attractive and stable in structure and excellent in ecological effect is formed.

Description

technical field [0001] The present invention relates to the design and construction field of revetment for rivers, lakes and other water bodies, in particular to an ecological revetment structure and revetment method, and especially to an ecological water revetment structure constructed using river and lake bottom mud in water body treatment projects and bank protection methods. Background technique [0002] A large amount of sediment in rivers and lakes and other waters seriously affects flood control, shipping and water regulation and storage functions. And as a large amount of pollutants are enriched in the sediment, when the water environment is disturbed, part of the pollutants in the sediment can return to the water phase from the sediment. Sediment has become an important pollution source of water pollution in rivers and lakes, and has a persistent impact on water areas. Therefore, sediment dredging is the most effective method in urban river and lake remediation an...
