Wet-land type gabion box retaining wall for river bank, and construction method of retaining wall

Abstract

The invention discloses a wet-land type gabion box retaining wall for a river bank, and a construction method of the retaining wall. The wet-land type gabion box retaining wall for the river bank comprises stepped gabion box retaining walls that are constructed on the two sides of the river bank; each stepped gabion box retaining wall is composed of primary gabion box cages and secondary gabion box cages; metallic meshes are arranged on the top of a water facing side of the secondary gabion box cages; adjacent metallic meshes are mutually connected; the metallic meshes and the water facing side of the primary gabion box cages form a strip groove; geotechnical cloths are surrounded in the strip groove; stainless steel fine meshes are cushioned between the water facing side of the strip groove and the geotechnical cloths; two layers of 8-shaped lacing wires are connected between the metallic meshes and a soil facing side of the primary gabion box cages; sandy soils are filled in the strip groove; and emergent aquatic plants are planted in the strip groove. According to the wet-land type gabion box retaining wall for the river bank, and the construction method of the retaining wall disclosed by the invention, the emergent aquatic plants are planted on the gabion box retaining wall, so that a landscaping effect of the river bank is reinforced, conditions are created for growth of plenty of aquatic animals and micro-organisms in a river-land ectone, as a result, the biodiversity of a river is increased, a self-cleaning ability and a runoff pollutant filtering ability of water are enhanced.

Description

[0001] technical field [0002] The invention belongs to the technical field of comprehensive improvement of rivers, and in particular relates to a wetland type river bank gabion retaining wall and a construction method thereof. [0003] Background technique [0004] The gabion mesh retaining wall revetment is filled with pebbles, block stones and other fillers in the honeycomb grid composed of steel wires, and stacked into a wall to form a soil or water retaining structure. It is different from traditional dry stone, mortar masonry, concrete hard Compared with revetment, it not only retains the characteristics of solid revetment structure, stability and strong erosion resistance, but also has the advantages of good water permeability, strong variability and good seismic performance. [0005] Although the gabion retaining wall has better developed the function of nutrient circulation between the river channel and the land, absorbing or gradually releasing floods, the gabion...

AI Technical Summary

Problems solved by technology

[0005] Although the gabion retaining wall has better developed the function of nutrient circulation between the river channel and the land, absorbing or gradually releasing floods, the gabion retaining wall is still monotonous and rigid, and it is difficult for aquatic plants in the river channel to survive large pebbles or blocks. The disadvantages of growing on rocks, poor biodiversity, poor filtering effect of runoff pollutants, and low self-purification ability of water bodies
