Description

Ecological retaining wall system

technical field

The invention relates to the field of civil construction engineering. More specifically, the present invention relates to an ecological retaining wall system.

Background technique

The retaining wall is a support for subgrade fill, natural slope, revetment, landscape wall and mountain slope, etc., and is a structure to prevent deformation and instability of fill or slope. Retaining walls are widely used in civil engineering, environmental engineering, ecological restoration engineering and landscaping projects. Retaining walls are usually fabricated with a supporting surface structure of interconnected blocks and earth or other fill material, placed behind the wall and compacted, and usually with geogrid rolls laid in layers of fill material within the wall timber, extends back from the wall and attaches to the wall. The common problem faced by these slopes is that they are easily eroded by rainwater, or damaged and collapsed due to displacement, deformation and shedding, which has great potential safety hazards, often causing serious accidents and high maintenance costs, and has no ecological and landscape functions. There are large constraints in the engineering of landscape requirements.

How to make the retaining wall stronger, safer, more economical and more convenient to implement, and how to make the retaining wall meet both the safety requirements of the project and the requirements of greening are the important goals of adapting to the national environmental protection policy.
