Problems solved by technology

However, there are certain limitations in the applicable life of these technical means, and they cannot maximize the safety and economic benefits of riverbank protection.
In addition, although these technical means have not completely blocked the accessibility of the river and the land, they have reduced the vegetation coverage of the bank slope to a certain extent, and even caused part of the bank slope to be exposed, affecting the ecological benefits and landscape effects of the bank slope.

specific Embodiment approach

[0026] Soft ecological revetment structure of the present invention, its preferred embodiment is:

[0027] Including bank slope toe protection structure and bank slope surface protection structure;

[0028] The protection structure at the foot of the bank slope includes a log-willow anchor cage, the anchor cage is made of log anchor piles, willow branch cutting anchor piles and fresh wicker, and the anchor cage is filled with gravel and sandy loam , the water surface on the back of the anchor cage is close to the backfilled sandy loam layer;

[0029] The bank slope protection structure is composed of fresh wicker and the sandy loam layer on the slope surface, the fresh wicker is evenly spread on the bank slope and the thick end is inserted into the sandy loam adjacent to the water surface on the back of the anchoring cage In the layer, the sandy loam layer on the slope refers to the backfill soil evenly covering the surface of the wicker.

[0030] Preferably, the log anchori...

Abstract

The invention discloses a flexible ecological bank protection structure and a construction method thereof. The flexible ecological bank protection structure comprises a bank slope toe protective structure and a bank slope surface protective structure; the bank slope toe protective structure comprises a log-willow branch anchoring cage, the log-willow branch anchoring cage is weaved from log anchoring piles, cuttage willow branch anchoring piles and fresh wickers, the anchoring cage is filled with gravel and sandy loam soil, and the air face of the anchoring cage fits backfill sandy loam soil layers; the bank slope surface protective structure is composed of the fresh wickers and the slope surface sandy loam soil layers, the fresh wickers uniformly are paved on the bank slope surface, the thick ends of the fresh wickers are inserted into the sandy loam soil layers adjacent to the air face of the anchoring cage, and the slope surface sandy loam soil layers refer to the backfill coveringon the surface of the wickers. According to the flexible ecological bank protection structure and the construction method thereof, the collapse of the bank slope can be prevented, corrosive materialscan provide nutrients for plant growth, the formed root systems improve the stability of the bank slope, local materials can be taken, the service life is long, the vegetation coverage and shielding water areas of the bank slope are improved, habitat space is provided for animals, and the ecological and landscape benefits in the region are improved.

Description

technical field [0001] The invention relates to a soft ecological revetment method, in particular to a soft ecological revetment structure and a construction method thereof. Background technique [0002] The riparian zone is the ecological transition zone between the terrestrial ecosystem and the aquatic ecosystem, and an important link for the exchange of matter, energy, and information between the two. Maintaining the stability of the riparian zone is of great significance for regulating water flow, buffering pollution, regulating climate, providing habitats for animals and improving the value of landscape recreation. Traditional river improvement projects often use hardened materials to protect bank slopes. Although this method has achieved the effect of strengthening bank slopes, it has high economic investment and poor sustainability. many adverse effects. [0003] River bank collapse caused by lateral erosion or local scour is an important problem in river bank manag...
