The construction of high-speed roads, railways, mines, water conservancy and other projects is often accompanied by a large amount of earth and stone excavation, which destroys the original vegetation, resulting in a large number of exposed slopes, causing serious soil erosion and unbalanced ecological environment. The slope formed in this type of project, relying on the power of nature itself to restore the ecological balance, often takes a long time, or even cannot be fully restored. Therefore, it must be usedSlope greening spraying machineThe slope protection and ecological greening treatment can prevent slope damage, soil erosion, water conservation, air purification and beautification of the environment.

Ecological greening slope protection is mainly to plant herbaceous land. Generally, herbaceous or woody plants that are dry, barren, developed root system, good coverage, easy to survive, easy to manage, and taking into account landscape effects should be selected. According to the actual situation of different sections, greening modes such as cluster planting and row planting can be adopted to achieve the collocation of arbor, shrub, flower and grass as far as possible to form plant communities with different landscapes. The technical principle of ecological greening slope protection plant configuration is: soil and water conservation, both ecological landscape effect. The slope protection should consider the gradual restoration of the whole vegetation, and the ecological model should be configured mainly by forest and grass plants, which is conducive to soil protection, soil erosion prevention, slope landscape improvement and slope protection effect.

When selecting plant species, we should pay attention to maintaining biodiversity, building a multi-tree, multi-structure, multi-functional ecological landscape with the combination of arbor, shrub and grass, effectively increasing the amount of green and green leaf area, tapping the potential ecological force per unit area, and improving the leaf area index. The whole greening along the line should pay attention to the three-dimensional space changes and rhythm.

Several common construction techniques for slope greening spray seeder

1. Concrete spraying (green) process This process can be used for slopes with steep slopes and good stability. Construction procedure: making and installing slope anchor nails and drain holes → hanging net (reinforcement connection) → spraying concrete (green) → concrete curing → dismantling scaffold

2. Spraying mixed planting process flow: slope surface treatment → laying net and nail net → spraying mixed planting → backfilling planting soil → curing First spray the mixture without seeds with a spraying thickness of 6~8cm, after the mixed soil sprayed once reaches a certain strength, after the second injection, the seeds treated by accelerating germination are added to the sieved peat soil, humus soil, binder, fiber, slow-release compound fertilizer and water retaining agent, and the mixed material is evenly stirred.

On the steep rock surface or rock surface of the slope, the slope greening spraying machine is used to spray the mixed guest soil to the ground with barbed wire hanging on the slope. Technological process: slope surface treatment → net laying, nailing → soil covering, sandblasting and seeds → maintenance precautions: ① net laying: attention should be paid when selecting PVC-plated or galvanized diamond wire mesh with a mesh of 4 × 4 cm or 5cm: ① net laying: select PVC-plated or galvanized diamond wire mesh with a mesh of 4 × 4 cm or 5 × 5 cm to lay the slope surface, and cut the length as required, groove and groove shall be fixed with mesh. After the roof is fixed, it is laid from top to bottom. The overlap width between the left and right nets shall not be less than 10cm. Nail net method: L-type Φ6~8 steel or bamboo anchor is adopted according to the situation of stone slope, and L-type Φ6~8 steel anchor nail is adopted according to the actual situation. ② The sieved humus soil, grass fiber, peat soil, slow release nutrient fertilizer, adhesive, water retaining agent, water and other mixed materials are fully stirred with a spraying machine, and then the materials and seeds are sent to the slope by the spraying machine, and sprayed on the wire mesh fixed on the slope in advance.
