Abstract In the construction of mountain roads, there will be a large number of excavation methods leading to vegetation damage and the production of engineering waste residue. In order to carry out long-lasting and effective vegetation restoration on high and steep rock slopes and make full use of engineering waste residue, this paper proposes a new combination structure and materials. The jet mixture base layer, the soil layer and the plant layer are combined. The base layer of the jet mixture consists of three parts: planting soil, engineering waste residue and cementing mate-rial. Soil Mulch Binder is added to the soil layer to improve the integrity and stability of the soil. The plant layer mixes the seeds with the Erosion Control Matrix. The combined structure is combined with the high-steep rock slope to achieve structural stability and anti-scour ability, improve the water retention of the structure, improve the germination rate, and meet the vegetation restoration durability under adverse environmental conditions.
