Cutting slope reinforced passive protection system and construction method thereof

The invention relates to a cutting slope reinforced passive protection system and a construction method thereof, and relates to the technical field of road construction. The cutting slope reinforced passive protection system comprises retaining walls, stand columns, a reinforcing mesh and an energy storage mechanism used for tensioning the reinforcing mesh, and one retaining wall is correspondingly provided with two stand columns. The two stand columns are arranged at the two ends of the retaining wall in the length direction respectively, the two ends of the reinforcing mesh in the length direction are arranged on the two stand columns respectively, a gap is formed between the reinforcing mesh and the retaining wall, the reinforcing mesh can move relative to the stand columns, and the energy storage mechanism is connected with the reinforcing mesh. The construction method comprises the steps that S01, the retaining wall is pre-poured; S02, the stand columns are poured; S03, retaining walls are connected to t
