Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of river channel slope protection, in particular to an ecological river channel slope protection structure. Background Art
[0002] Slope protection structures need to be set up on both sides of the river to fix and protect the soil on both sides of the river. The existing traditional slope protection is mainly based on earth excavation and adopts the form of retaining wall. The river bank is built into a wall-type slope protection or slope slope protection using stones, concrete box frames or concrete blocks, so as to achieve flood control, water transportation, irrigation and other functions. Traditional wall-type slope protection or slope slope protection is mostly artificial hard slope protection, which cuts off the ecological process of the urban river itself and lacks ecological considerations. The traditional artificial hard slope protection has poor permeability, which cuts off the connection between the river water body and the two banks. The water body and the land are forcibly divided into two unfamiliar parts, which accelerates the decline of riverbank plant communities, destroys the role of the river as a link between the water ecosystem and the terrestrial ecosystem, weakens the ecological service function of the river, and loses the river's own "metabolic ability" and vitality, which seriously restricts the improvement of the water environment and has a very poor ecological effect. The water in the river is prone to river ecological environment problems such as odor and eutrophication; in addition, traditional artificial hard slope protection can only form an extremely simple and boring canal, which also brings great limitations to the surrounding landscape planning.
[0003] In recent years, river slope protection has gradually adopted the form of ecological bank protection, among which soil and water conservation blanket slope protection is widely used. Soil and water conservation blanket slope protection is a three-dimensional structure similar to a loofah network used for planting grass and consolidating soil. The soil and water conservation blanket is loose and flexible. There are 90% to 95% gaps in the net, which can be filled with soil, gravel and fine stones. Plant roots can pass through it and grow comfortably, neatly and evenly. The grown turf makes the net mat, turf and soil surface firmly combined together to form a solid green composite protective layer. However, the existing soil and water conservation blankets are mostly fixed with metal materials such as steel nails and steel bars. There is a problem of rusting of the fixing materials. In addition, the simple planting of grass and the single plant species have no significant landscape effect. The safety of the riverbank structure during the flood season is also greatly tested.
[0004] In view of this, the inventor has designed an ecological river slope protection structure based on many years of production design experience in this field and related fields and through repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content

[0025] The details of the present invention can be more clearly understood by combining the accompanying drawings with the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used for the purpose of explaining the present invention and cannot be understood as limiting the present invention in any way. Under the guidance of the present invention, technicians can conceive of any possible variations based on the present invention, which should be considered to belong to the scope of the present invention.
[0026] like Figure 1 As shown, the utility model proposes an ecological river slope protection structure 100, which includes a slope body 10, a soil and water conservation blanket 20 and a plurality of living plant piles 30. The slope surface 11 of the slope body 10 has a rock and soil layer. The soil and water conservation blanket 20 covers the rock and soil layer and is fixed by a plurality of living plant piles 30. Each living plant pile 30 penetrates the soil and water conservation blanket 20 and is implanted in the rock and soil layer.
[0027] The ecological river slope protection structure 100 proposed in the utility model adopts the form of combining a soil and water conservation blanket 20 and a living plant pile 30. The soil and water conservation blanket 20 is fixed by the living plant pile 30. After the living plant pile 30 is implanted in the rock and soil layer, the living plant pile 30 grows a root system. The interaction between the plant root system and the rock and soil (that is, the root anchoring effect) is used to protect and reinforce the surface of the slope, so that it can not only meet the requirements for the stability of the slope surface, but also restore the damaged natural ecological environment and improve the landscape of the waterfront area.
[0028] The ecological river channel slope protection structure 100 proposed by the utility model adopts living plant piles 30 to fix the soil and water conservation blanket 20. In the later stage, the living plant piles 30 grow roots to enhance the soil fixing effect, effectively avoiding the problem of rust of traditional metal fixed soil and water conservation blankets, highlighting the concept of environmental protection, simple construction operation, and convenient operation and maintenance. At the same time, the ecological bank connects the vegetation in the waterfront area with the vegetation in the embankment to form an aquatic and terrestrial composite biological symbiotic ecosystem. The plant piles form an ecological community with good landscape effect.
[0029] The ecological river slope protection structure 100 proposed by the utility model uses living plant piles 30 to fix the soil and water conservation blanket 20 on the slope body 10, so that the vegetation in the waterfront area and the vegetation in the embankment are connected as a whole, forming an ecosystem of water-land compound biological symbiosis. In the flood season, the river water infiltrates and stores in the groundwater layer outside the embankment. In the dry season, the groundwater infiltrates back into the river through the embankment, playing the role of replenishing the dry season and regulating the water level. At the same time, living plants and other organisms can absorb and decompose a large amount of pollutants in the river water, thereby purifying the water body appropriately and enhancing the self-purification effect of the water body.
[0030] In an optional embodiment of the utility model, a levee shoulder 12 is provided at the top of the slope body 10, a levee foot ditch 13 is provided at the bottom of the slope body 10, and a soil and water conservation blanket 20 is laid between the levee shoulder 12 and the levee foot ditch 13. With the above structure, the soil and water conservation blanket 20 is laid downward from the levee shoulder 12 and wraps the slope surface 11, and after being laid to the levee foot ditch 13, a plurality of living plant piles 30 are implanted.
[0031] In an optional example of this embodiment, a plurality of living plant piles 30 are respectively provided at the top and the bottom of the soil and water conservation blanket 20 , and the plurality of living plant piles 30 are sequentially spaced along the length direction of the slope body 10 .
[0032] In an optional example of this embodiment, the total length of the soil and water conservation blanket 20 from the embankment shoulder 12 to the embankment foot ditch 13 is about 150 cm.
[0033] In an optional example of this embodiment, a plurality of soil and water conservation blankets 20 are sequentially laid along the length direction of the slope body 10 , two adjacent soil and water conservation blankets 20 are overlapped, and a plurality of living plant piles 30 are arranged at the overlapping positions.
[0034] In an optional example of this embodiment, the reserved overlap width of the soil and water conservation blanket 20 is 10 to 15 cm.
[0035] In an optional example of this embodiment, two adjacent soil and water conservation blankets 20 are overlapped by pressing the upstream against the downstream.
[0036] In an optional example of this embodiment, at the overlapping position, a plurality of living plant piles 30 are sequentially arranged at intervals along the slope direction of the slope body 10 , and the distance between two adjacent living plant piles 30 is 1 m.
[0037] In an optional embodiment of the utility model, the soil and water conservation blanket 20 has a grid-shaped mesh mat, the meshes of the mesh mat are filled with soil, gravel and fine stone for planting turf. The grown turf firmly combines the mesh mat, turf and soil surface together to form a solid green composite protective layer with stronger anti-scouring ability.
[0038] In an optional example, the soil and water conservation blanket is made by a monofilament dry-drawing process. The fiber filaments are extruded into a three-dimensional structure at one time, and can be water-cooled without going through an intermediate stage. Due to the special properties of its petrochemical material, the fiber has a memory of its original shape after molding. The surface tension of the fiber in the soil and water conservation blanket is not damaged, the three-dimensional shape is not deformed, and the product has good mechanical properties, chemical stability, and structural stability.
[0039] The one-dimensional space of the soil and water conservation blanket provides sufficient space for the growth of plants. After the plants mature, they can also provide additional strength for the plants, enabling them to resist higher-intensity water flow on the surface of the soil layer. At the same time, the mature plants on the surface of the soil layer also play a role in consolidating the soil, effectively preventing water loss caused by gravity, runoff scouring, river scouring, etc.
[0040] In an optional embodiment of the present invention, the outer diameter of the living plant stake 30 is 5 cm.
[0041] In an optional embodiment of the present invention, the height of the living plant stake 30 is 80 cm.
[0042] In an optional embodiment of the present invention, the living plant pile 30 is a willow stem, which gradually grows into a willow tree after planting, which not only protects the soil and water conservation blanket 20 and the slope 11, but also has a good landscape effect. Of course, the living plant pile 30 can also be other greening trees.
[0043] The ecological river slope protection structure 100 proposed by the utility model adopts a type that combines a soil and water conservation blanket 20 and a living plant pile 30. The living plant pile 30 is used to replace the traditional method of fixing the soil and water conservation blanket 20 with metal, highlighting the concept of ecology and environmental protection. The plant root system is used instead of metal materials to anchor the soil and water conservation blanket 20, thereby improving the soil fixing ability and anti-impact ability and facilitating construction and maintenance. The plant piles form an ecological community with a good landscape effect. The living plant piles and other organisms can absorb and decompose a large amount of pollutants in the river water, thereby appropriately purifying the water body.
[0044] The detailed explanation of the above-mentioned embodiments is only intended to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions cannot be interpreted as limitations on the present invention for any reason. In particular, the various features described in different embodiments may also be arbitrarily combined with each other to form other embodiments. Unless there is a clear description to the contrary, these features should be understood to be applicable to any embodiment and are not limited to the described embodiments.
