Background

During the use of the highway side slope, diseases such as slope stripping and the like are caused by rain wash, climate change and other reasons, and pit slots with different damage degrees are formed. At present, the treatment of side slope pits generally has the following modes: when the pit range is smaller or the depth is shallower, the treatment is not carried out; when the pit slot is large in range or deep, masonry rubbles or concrete are adopted for filling to carry out masonry protection; if the conditions allow, the slope is brushed again, and the slope surface is protected again after the stable slope rate is achieved.

The pit diseases are not treated, and the diseases are further increased under the influence of rainwater erosion and other external factors, so that potential safety hazards are formed for road use. By adopting masonry protection, the side slope diseases can be functionally repaired, but because the masonry protection environment adaptability is poor, particularly, the pit slot range is often generated in the local part of the side slope, the side slope surface after treatment is different from the adjacent side slope protection form, and becomes a local multi-position discontinuous 'patch', and the landscape is extremely poor for high-grade roads.
