the concrete prefabricated parts are built on the bank slope of the river channel in a step-like manner, through planting holes are reserved on the concrete prefabricated parts, and the bank slope is protected through horizontal stacking.

The river bank slope has the slope gradient meeting the self-stability requirement under the operation condition and is realized by slope building.

The gabion mesh foundation part is a galvanized steel wire mesh with built-in block stones or pebbles, and the section of the gabion mesh foundation part is in a trapezoidal gravity type retaining wall form.

The concrete prefabricated part is prefabricated by conventional fine-stone concrete, the size of the concrete prefabricated part is determined according to the designed stable gradient of the river bank slope, and the concrete prefabricated part is in a front-back step shape.

The planting holes are aligned up and down after being built, planting soil is filled in the planting holes for planting, and the step surface is horizontal.

The planting soil is suitable for plant growth, is filled in the planting holes and is connected with the bank slope of the river, and water-resistant herbaceous plants suitable for local growth conditions are planted on the planting soil.

Compared with the prior art, the utility model has the advantages that:

the utility model discloses an ecological bank protection structural design method through gabion net basis protection slope toe, builds concrete prefabricated component protection bank slope by laying bricks or stones, prevents that rivers from scouring the bank slope and causing soil erosion and water loss, and the river is stabilized from the face. The gabion mesh foundation has a certain gap, so that aquatic animals can inhabit and breed conveniently. The precast concrete components are in a step shape after being built, slope planting is changed into step type horizontal planting, planting soil is not easy to be washed away and lost by flood, and plant growth is facilitated. After the plants grow, the roots of the plants go deep into the bank slope, so that the slope protection structure is closely connected with the original bank slope, and the bank slope is better protected. The ecological bank protection structure of the design method is communicated with the original bank base and the river, so that river water and slope soil of the original bank can mutually permeate, the ecological function of a natural river channel is kept, and the ecological bank protection structure has a natural landscape effect.
