Abstract

The invention discloses an expansive soil slope support structure and a construction method thereof. Through the expansive soil slope support structure and the construction method thereof, the problemthat a support of an expansive soil slope is prone to being damaged and thus loses efficacy is solved, and the problems that outside moisture enters a slope soil mass, and a protection structure is cracked can be effectively solved. According to the technical scheme, the expansive soil slope support structure comprises a water-permeable and water-drainage assembly and a vegetation protection assembly; the water-permeable and water-drainage assembly comprises a waterproof geotextile arranged on the expansive soil slope, and a water-permeable concrete layer is arranged on the waterproof geotextile; and the vegetation protection assembly comprises a backfill soil layer arranged on the water-permeable concrete layer, and a vegetation layer is arranged on the backfill soil layer.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an expansive soil slope support structure and a construction method. Background technique [0002] Expansive soil is a kind of soil containing hydrophilic minerals. When it is wetted by water, its volume will expand significantly and its strength will decrease rapidly, resulting in disintegration, softening and poor erosion resistance; when it dries and loses water, the soil will shrink significantly and the soil will be hard. It has obvious cracks and is easy to break, and the process of water absorption and water loss shrinkage of expansive soil is reversible. Due to its remarkable damage, in the early traffic engineering, it even came to the conclusion that "every ditch will collapse, and no embankment will not collapse", which shows its destructive power. [0003] At present, most of the existing treatment schemes are rigid support. Rigid support refers to the tre...
