Description
Technical Field
The utility model relates to the field of geotechnical engineering, in particular to an ecological toughness lattice anchoring structure for protecting an expansive soil slope, and belongs to the technology for comprehensively ensuring the surface protection and deep anti-slip ecological support of the steep expansive soil slope.
Background
The expansive soil shows remarkable hydrophilicity and swelling property because of being rich in hydrophilic minerals such as montmorillonite and the like. Expansive soil slopes in natural environments experience severe wet and dry cycles due to rainfall-evaporation. Under the action of the dry and wet circulation, the expansive soil can undergo repeated water absorption expansion, water loss shrinkage cracking, the strength is greatly reduced, and the instability and damage of the expansive soil slope are caused. Some supporting measures are developed aiming at the damage of the expansive soil slope, and the main supporting measures at present are rigid supporting, flexible supporting and ecological slope protection technologies.
Because of the specificity of expansive soil, the traditional rigid slope protection mode is not suitable for protecting the expansive soil slope. The swelling deformation of the expansive soil under the rainfall-evaporation effect is very remarkable, for example, rigid protection such as a grouted rubble skeleton, a dry rubble and the like can generate the swelling deformation under the soil body effect, and the poor coordinated deformation capability is easy to lose efficacy under the effect of repeated swelling and shrinkage cycles of the soil body. The flexible supporting structure has better ductility, allows the expansive soil to generate certain deformation, realizes 'soft treatment of expansion', and ensures the stability of the slope. However, the existing flexible support technology such as geogrid, geotechnical bags and the like has the problems of complex construction process, high later maintenance cost, poor durability, non-ideal long-term support effect and the like, and has limited support capability on side slopes with deeper sliding surfaces. In addition, the two supporting methods still can cause water and soil loss on the surface layer of the expansive soil side slope, and the slope protection and ecological treatment effects are poor.
The ecological slope protection technology is a slope protection technology mainly composed of plants or geotextiles and plants. The method is characterized in that the embedded anchoring effect of the plant root system and the soil mass is utilized to protect the surface layer of the side slope, thereby meeting the requirement of stabilizing the surface layer of the side slope and recovering the damaged natural ecological environment. At present, the ecological slope protection technology of the expansive soil side slope also has some defects: the geotextile is not firmly combined with vegetation, soil is easy to erode or wash away, the later maintenance cost is higher, and the side slope support capability for a deeper sliding surface is limited.
