The invention discloses an ecological slope protection structure for a high and steep spray-sowing side slope in an arid area and a construction method of the ecological slope protection structure. The ecological slope protection structure can meet the long-term growth requirements of plants. The ecological slope protection structure for the high and steep spray-sowing side slope in the arid area comprises a concrete slope and a reinforcing mesh, and further comprises at least two rows of vegetation recovery mechanisms which are arranged in a spaced mode in the inclination direction of the slope surface of the high and steep side slope. Each row of vegetation recovery mechanism comprises at least two vegetation recovery grooves which are formed in a spaced mode. Each vegetation recovery groove comprises a recovery groove enclosing wall, a concrete layer arranged on the bottom surface of the vegetation recovery groove, and an anti-seepage paint layer arranged on the concrete layer. A sand gravel under layer, a planting soil layer and a covering layer are sequentially arranged in each vegetation recovery groove from bottom to top. The ecological slope protection structure is a novel slope protection structure which integrates a spray-sowing slope protection structure and the vegetation recovery mechanisms, the planting soil layers communicate with water and soil matrixes located in the high and steep side slope and used for plant growth and have the good water-retaining property, and the requirement for the water and soil matrixes for long-term growth of plants in the arid area is met.
Description
technical field [0001] The invention belongs to the field of slope protection, and in particular relates to an ecological slope protection structure and a construction method for high and steep spray-mixed slopes in arid areas. Background technique [0002] A high and steep slope refers to a slope with a soil slope height greater than 20m to less than 100m or a rock slope height greater than 30m to less than 100m, and a slope greater than 60°. In the process of infrastructure construction such as transportation, mining, water conservancy and municipal facilities, for unstable high and steep slopes, it is necessary to adopt large-scale hanging nets and spray mixing (spray mixing refers to the construction method of spraying and pouring fine stone concrete with a pressure spray gun) and other measures. However, the slope after spraying does not have the basic material conditions required for plant growth, and at the same time isolates the water and soil conditions for plant g...
