Hydroseeder machine for erosion control
1. Overview of the Hydroseeder machine for erosion control:
Hydroseeder machine for erosion control is to make the guest soil form a granulated structure with agglomerates. The reinforced fibers play a role in the reinforcement of a network similar to plant rhizomes, thereby creating a certain thickness of rain and wind erosion, firmness and ventilation, and natural Porous and stable soil structure with similar or better topsoil.
Technical points of Hydroseeder machine for erosion control:
1. The spraying substrate is an important factor for the success of spraying.
Peat soil is a good material for spraying. It can be mixed with wood fiber (or pulp) according to a certain ratio. It has better adhesion and water retention performance than pure wood fiber alone. It can be thin and very barren in the soil layer. , Even spraying on the slope of weathered rock, the thickness of spraying is generally 10-20cm.
2. The amount of water retaining agent and adhesive.
The water-retaining agent can be adjusted according to the different climatic conditions and the characteristics of the rock field; the adhesive can be determined according to the slope of the rock wall, which is proportional to the slope.
3. Hang the net. First fix the anchor nails on the stone wall at a certain interval, and then hang the net.
4. Grass seed selection
The grass seed to be sprayed should be a perennial variety with well-developed root system, fast growth, drought resistance, and barren tolerance; if the local winter is cold, the frost resistance of the variety should also be considered.
5. Mixed broadcasting.
Use the complementarity of grass species, such as deep rooting and shallow rooting, legumes and grasses, field and local, early and late development, and other characteristics for mixed spraying.
Set up a safety protection zone: near the construction site, pedestrians and vehicles are prohibited from passing, the safety protection zone is defined, and facility workers are marked at both ends of the construction site.
According to the requirements of the construction safety operation specification, select safety protection measures, erect steel pipe scaffolding, lay moso bamboo scaffolds underneath, hang protective nets, or hang ropes from the top of the mountain and fasten safety belts for construction. The scaffold erection is carried out in accordance with the scaffold erection facility engineering specifications, and the on-site construction personnel wear safety helmets and necessary labor protection equipment.
Hydroseeder machine for erosion control according to the nature of the soil or rock surface of the construction work surface, local climate conditions, construction season, and combine the growth characteristics of various plants, and increase the seeds of native tree species on the work surface of similar landforms in the local area, so that the secondary vegetation will be available in the future. Gradually integrated with the natural ecological vegetation during the year, without any traces of artificial carving.
Soak the seeds of arbor and shrub with 80℃ hot water (with seed soaking agent) for 1 day. Soak the seeds of herb plants for 1-2 hours before spraying so that the seeds can absorb water and moisturize.
Mix the treated seeds with fiber, adhesive, water retention agent, compound fertilizer, slow-release fertilizer, microbial fertilizer, etc., into a spraying slurry through a spraying planter. Under the action of the spraying pump, spray evenly on the work site. Operation surface.
For the rainy season, the plant seeds are protected from rain before taking root; the plant seeds and seedlings are protected from freezing damage in the cold season; and the heat preservation and moisturizing in the normal construction season. It is required to use non-woven fabric (or straw curtain) to cover, and strive to be careful, so as to prevent the early non-woven fabric from being blown away by the wind. The purpose is to prevent the working surface after forming from being washed by rain; the other is to keep warm and moisturize and promote plants.
