slope protection hydroseeder
The land-spraying is often carried out in an environment with poor site conditions and relatively complex geological structures. Slope protection hydroseeder is widely used in ecological protection projects for slope greening such as roads (railways), mines, riverbank slopes, and quarries.
Technical points of slope protection hydroseeder:
1. Grass species selection. The grass species to be sprayed should be perennial varieties with developed roots, fast growing, drought-resistant and barren-resistant; if the local winter is cold, the frost resistance of the portable hydroseeder varieties should also be considered.
2. Hanging the net. First fix the anchor nails on the stone wall at a certain distance, and then hang the net.
3. Mixed broadcast. The use of grass species complementarity, such as deep roots and shallow roots, legumes and grasses, field and local, early development and late development, mixed spray.
4. The amount of water retention agent and adhesive. The water retaining agent can be adjusted according to the climatic conditions of each place and the characteristics of the stone field; the binder can be portable hydroseeder determined according to the slope of the stone wall, and is proportional to the slope.
5. Spraying the substrate is an important factor to ensure the success of the spray. Peat soil is a good material for spraying. It can be mixed with wood fiber (or pulp) in a certain ratio. It has better adhesion and water retention than pure wood fiber alone. It can be thinner and very thin in the soil layer. Even the surface of the weathered rock is sprayed, and the general thickness of the spray is 10-20 cm.
