Description

Ecological slope protection system suitable for plateau mountains

technical field

The utility model relates to the technical field of slope protection, in particular to an ecological slope protection system suitable for plateau mountainous areas.

Background technique

Slope protection refers to the collective designation of paving and planting on the slope surface to prevent the slope from being scoured. For large-scale slopes, it is difficult to greatly improve the overall stability of the slope through the anchor-sprayed structure of the traditional anchor bolt combined with the sprayed concrete surface. For very steep slopes, the anchor-sprayed construction is carried out on the slope surface. It is very difficult. The large area of shotcrete on the slope not only destroys the original natural landscape, but also the corresponding greening is difficult to carry out or maintain effectively for a long time; prestressed anchor cables are reinforced, and the slope surface is prestressed on the anchor cables. When the slope surface is required to have greater rigidity, otherwise the prestress will be lost due to the deformation of the rock and soil mass in the tension section. At the same time, it is difficult to apply when the geological conditions are relatively complex or the survey data is insufficient. Especially for the slopes of the plateau mountains, the soil generally has the characteristics of rough texture, thin soil layer, low nutrient, and easy sandification, which makes the slopes of the plateau mountain areas prone to disintegration and soil erosion. Slope protection is particularly important.
