Therefore, the utility model adopts the following technical scheme:
the utility model provides a green ecological slope protection structure in hydro-fluctuation area which characterized in that: the slope toe outside soil body is laid and is pitched outside protective layer, sets up plain concrete toe mound on the slope toe, and the slope inclined plane sets up the inclined plane layer of protecting slope, and slope top covers and cultivates the soil layer, the inclined plane layer of protecting slope includes by domatic reverse filter layer, transition layer, planting layer, the non-woven geotechnological cloth of oozing outwards setting gradually and overburden.
Further: the upper cladding is formed by combining concrete grids and pervious concrete bricks.
Further: the planting layer comprises planting soil, nutrient medium and plant seeds.
Further: and the outer side protection layer of the toe is second water-permeable non-woven geotextile, and is compacted by throwing and filling a stone layer.
Further: the slope protection layers are paved in a subarea mode, and a berm is arranged between different slope protection layers.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model can not only form a green vegetation facing, has better anti-seepage effect, but also has better stability compared with the common facing, has simple structural style and is easy to be applied to the actual engineering; the utility model discloses have good anti erosion and corrosion resistance ability, when rivers erode the soil body, effectually will concentrate stress diffusion, prevent that the slope toe outside soil body from receiving exogenic action and destroying.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
As shown in fig. 1-4, the utility model provides a green ecological slope protection structure for a hydro-fluctuation area, the slope 1 is characterized in that a slope foot outer protection layer 4 is paved on the soil body on the outer side of the slope 1, the slope 1 is a side slope generated in engineering, the slope foot outer protection layer 4 can protect the soil body on the outer side of the slope foot from excessive loss when washed by water flow, plain concrete toe piers 5 are arranged on the slope foot of the slope 1, a slope protection layer 3 is arranged on the slope of the slope 1, the plain concrete toe piers 5 are used for supporting the slope protection layer 3, the slope protection layer 3 is a core structure of the whole slope protection structure and is used for forming a green vegetation protection surface to enhance the scouring resistance and the erosion resistance, the slope 1 is covered with a soil planting layer 2, and grass seeds are sprayed, and the slope protection layer 3 comprises a reverse filter layer 14, a transition layer 13, a planting layer 12, a first water-permeable non-woven geotextile 11 and an upper covering layer 10 which are sequentially arranged from the slope surface to the outside.
The selected first water-permeable non-woven geotextile 11 has good air permeability and water permeability, and has the functions of intercepting soil particles and protecting soil, the transition layer 13 and the reverse filter layer 14 protect the soil body of the planting layer 12 from loss, the reverse filter layer and the transition layer filler are composed of sand and gravel, the thickness is respectively 50cm and 30cm, the requirement gradation is continuous, specific parameters are determined by indoor experiments, the material is pushed by a bulldozer to be smooth after being unloaded, the reverse filter material and the transition layer material are manually matched with a flat bin, the relative density is not less than 0.7, the paving thickness is checked by a level gauge after each layer of paving, and the paving is timely processed when the paving thickness is too thick.
The upper cladding 10 is formed by combining the concrete frame 8 and the pervious concrete bricks 9, the thickness of the upper cladding 10 is not more than 200mm, the porosity of the pervious concrete bricks 9 is required to meet the growth requirement of the selected plants, and the strength is required to meet the construction requirement.
