Detailed Description

The invention will be further described with reference to specific embodiments below:

as shown in fig. 1 and 2, the utility model provides a novel ecological water shoreline, the whole is a stepped shoreline 1 composed of earth and stones, a retaining wall 2 is arranged in front of each step, the retaining wall 2 comprises a gabion 3 and a stone block layer 4 piled inside the gabion 3, a vegetable layer 6 is planted on the gabion 3, preferably vine climbing plants, and the gabion 3 is made of high-strength steel bars; a groove is arranged at the step below the retaining wall 2, fine particles 14 are filled in the groove to form a filter layer 5, and a layer of metal mesh 16 covers the filter layer 5; meanwhile, planting areas are also arranged on each step for planting different plants; when rainfall occurs, rainwater falls into the planting area, when the speed of rainwater permeation of the planting area is slower than that of rainfall, water flow flows into the gabion 3 along the terrain after being accumulated in the planting area, firstly passes through vine climbing plants on the gabion 3, and then flows into the filter layer 5 along gaps among stones of the stone layer 4, garbage, large particles and the like possibly existing before the water flow are well filtered by the stone layer 4 and the vine climbing plants 6, and soil which carelessly flows into the filter layer 5 can be filtered by the metal net 16 covered on the filter layer 5; fine particles 14 are filled in the filter layer 5, and water flow is secondarily filtered in the area and slowly flows to a lower stage ladder; through the multilayer physical filtration of laying on the water bank line and the effectual soil erosion and water loss that has reduced of the stagnated of vegetable layer to play filterable effect.

Preferably, the fine particles 14 filled in the filter layer 5 comprise sand, small stones and the like, and because gaps between the sand and the small stones are small, fine impurities can be effectively filtered out for the second time, and the water loss is slow, after rainfall is finished, water in the filter layer 5 slowly permeates into the vegetation layer through the water permeating film a13, so that the soil is ensured to be wet, plants in various vegetation areas are nourished, rainfall resources are effectively utilized, and the cost of manual maintenance is reduced; meanwhile, the water seepage film a13 can effectively isolate the soil and the filter layer 5 and prevent the soil and the filter layer from mixing with each other.

Preferably, the metal mesh 16 may be a wire mesh with a small pore size, which can effectively block the soil and large particles that are not filtered by the retaining wall 2 from entering the filter layer 5, and the wire mesh also reinforces the filter layer to prolong the service life.

Preferably, the stone layer 4 is made of large cobblestones with the particle size of 20-30cm, the cobblestone surface is smooth, water seepage is fast, the cobblestones with the particle size are stable, the mass of each cobblestone is large, the cobblestones cannot be flushed out of a gabion due to overlarge water flow, and the effect of reinforcing the embankment can be achieved under the combination of the cobblestones with the reinforcement gabion; the retaining wall 2 with the gabion 3 as the main body protects the soil body and the vegetation layer on each stage of stairs and reduces the damage caused by physical impact of water flow.

Preferably, the soil-side end of the retaining wall 2 is covered with a water-permeable film b15 to isolate soil, the material used may be the same as the water-permeable film a13, or other water-permeable material, which can prevent soil from falling into the gabion 3 to cause blockage or be directly carried into the river by water flow; if the cost is limited, the retaining wall can be laid only at the lowest retaining wall 2, so that the soil can be prevented from being brought into the river by the recoil of river water.

Preferably, different plants are planted in the planting areas among the steps of each level according to different levels, an aquatic plant vegetation layer 10 is arranged on the planting platform 7 in the water-free area, the planting platform 7 in the water-free area is in a state of being submerged by water for most of the time, the aquatic plant vegetation layer 10 can adopt reworked flowers, copper cash plants and the like, the aquatic plant planting has the advantages that the life of the aquatic plant is tenacious, the aquatic plant can adapt to different living environments, the aquatic plant can effectively improve an underwater ecological circle, and the purpose of improving water quality is achieved; a vegetation layer 11 is arranged on a waterside planting platform 8, the waterside planting platform 8, namely the platform, can be submerged by water when the water level rises, the vegetation layer 11 is preferably selected from lawns, trachelospermum and the like, and the vegetation can well consolidate soil and prevent soil in a slope body from being brought into water when river water rises; the arbor and shrub plant vegetation layer 12 is arranged on the planting platform 9 in the far-water area, namely the platform is close to a road and is at least 5-8 unit steps away from a water source, the arbor and shrub plant vegetation layer 12 is preferably made of trachelospermum jasminoides, iris tectorum, willow and the like, and the arbor and shrub plant vegetation layer 12 has high ornamental value and plays a role in beautifying a water shoreline; the plants can assist in filtering water flow during rainfall.
