An ecological bag reinforced retaining wall and its application

Abstract

The invention discloses an ecological bag reinforced earth-retaining wall. The reinforced earth-retaining wall consists of multiple layers of ecological bags, wherein each ecological bag contains original soil of a site where the reinforced earth-retaining wall is to be placed or foreign soil and also contains one or more components which are added into the original soil or the foreign soil to beused to improve the soil quality; and the one or more components added into the original soil or the foreign soil are determined according to the PH value, the organic matter and the ammonia-nitrogencontent of the original soil or the foreign soil as well as one or more components in the soil separates. The ecological bag reinforced earth-retaining wall provided by the invention can avoid displacement, deformation and falling off and can be applied to ionic-type rare-earth mining areas in southern China, ecological buffer zones, ecological grassed swales, earth-retaining walls for wetlands, ecological rehabilitation projects for drainage basin revetments, road side slope projects, ecological rehabilitation projects for mines, rehabilitation technologies for black and odorous water bodiesand other fields. Moreover, the ecological bags of the ecological bag reinforced earth-retaining wall are filled with the soil and the different components added into the soil, and materials adopted for the different components are economical, efficient and green, so that migration of harmful elements in contaminated soil at the site where the reinforced earth-retaining wall is to be placed can beeffectively prevented and the quality of the contaminated soil can be improved.

Description

technical field [0001] The invention relates to a retaining wall, in particular to an ecological bag reinforced retaining wall and application thereof. Background technique [0002] Retaining walls are widely used in civil engineering, environmental engineering, ecological restoration works, and landscaping projects, such as supporting slopes and embankments of highways, supporting noise barriers, and more. 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. [0003] In the prior art, there are three methods for building engineering slopes: (1) natural earth-rock (infinite soil) method, design and determine slope according to the compressive and anti-shear strength of earth-rock itself; (2) hard body (cement, (stone, ...

AI Technical Summary

Problems solved by technology

Although the sandbag retaining wall can avoid being eroded by rainwater, the structure of the retaining wall is unstable, especially when the slope of the retaining wall is large, it is prone to displacement, deformation and falling off

[0005] In addition, the retaining walls of the prior art are not suitable for some areas where the original soil is polluted (such as ion-type rare earth mining areas) or areas where the soil needs to be repaired
