Application of slope protection greening technology in rock slope

The application of greening technology for rock slope protection includes high-order aggregate slope greening technology, mixed spraying technology, hanging net and foreign soil spraying technology, hole planting technology and mixed spraying technology.

1. High-order granular slope greening technology: plant seeds and growth substrates are sprayed on rocks, high-rise slopes, mines and other slopes by special spraying equipment to form excellent and stable granular structure, which can effectively prevent rain and soil erosion.

2. Mixed spraying technology: This technology is mature. Spraying mixed dry materials such as soil, fertilizer, organic matter, water-retaining materials, plant seeds, cement, etc. on the rocky slope with special spraying machinery creates a porous and stable planting substrate, which can not only make plants grow and develop, but also be washed away by rain.

3. The technology of hanging net and spraying soil: It is suitable for stable rock slopes, and it has been widely used in rock slopes of expressways, railways and mines.

4. Cave planting technology: digging holes at a certain distance on the rock slope and filling them with plant growth matrix and foreign soil, which is suitable for soil slopes and gentle rock slopes.

5. Spray-mixed planting technology: it is a slope treatment method with simple construction, low cost and good treatment effect, especially suitable for harsh geological environment that is not suitable for greening.
