Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, and in particular relates to a rock and soil slope protection device. Background Art

[0002] At present, there are three main types of rock and soil slope protection devices: (1) Rigid protection devices, such as mortar or dry masonry stone protection, cast-in-place concrete protection, and precast concrete block protection, but they are expensive, seriously damage the ecology, and are gray. At the same time, stress concentration is easy to occur inside the soil, causing embankment breach or collapse; (2) Flexible slope protection, such as vegetation turf, vegetation bags, geotechnical greening nets, water-sprayed grass seeds, stone cages, etc., but they are easily washed away by rainwater to form deep grooves, with poor protection effect, affecting the landscape, low safety factor, difficult to control quality, and large limitations. Some of the organic materials used are prone to aging problems that are difficult to solve; (3) Ecological slope protection devices, which not only have high strength like ordinary concrete, but can also be planted with grass and trees like soil, which not only meets the protection requirements of the slope, but also meets the ecological needs.
