Background technique

During the use of highway slopes, due to rain erosion, climate change and other reasons, diseases such as slope peeling are often caused, and pits and grooves with different degrees of damage are formed. At present, there are generally the following methods for the treatment of slope pits: when the range of the pits is small or the depth is shallow, it is not treated; when the range of the pits is large or the depth is relatively deep, rubble rubble is used. Or concrete filling, and masonry protection; if conditions permit, the slope shall be re-brushed, and the slope shall be re-protected after reaching a stable slope rate.

If the pit and groove disease is not treated, the disease will further increase under the influence of rain erosion and other external factors, which will pose a safety hazard to road use. The use of masonry protection can functionally repair slope diseases. However, due to the poor environmental adaptability of masonry protection, especially the range of pits and grooves often occurs in local slopes, resulting in the treated slope surface and adjacent slopes. The protection forms are different, and it has become a local discontinuous "patch". For high-grade roads, the landscape is extremely poor.

If the protection is carried out after re-brushing the slope, the large excavation method often causes damage to the original slope rock and soil and the protection method due to the large scope of the brushed slope, which will inevitably lead to higher construction costs.
