Description
Technical field
The present invention relates to solid wastes to utilize environment protection field, specifically a kind of ecological revetment brick and preparation method thereof.
Background technique
Landslide Hazards can all occur every year for China, and in summer, this kind of geological disaster is especially wreaked havoc.Companion when landslide occurs
As the Rock And Soil that certain side measures is moved to lower from eminence, on the way building or personnel cause damages or injures and deaths.For
The generation for effectively avoiding landslide disaster will carry out Design of Reinforcement for instable slope in Slope Design, to guarantee side
Slope keeps stable state in operation stage.
Common slope surface bank protecting method is mainly two kinds of modes, one is in slope surface linked network or sash is built, then spray by
Peat, stalk, decomposed animal waste, adhesive, water-retaining agent, fertilizer and vegetable seeds composition bulk matrix are afforested, such as steel
Muscle cement sash method, soil moved in improve the original tape planting method, fiber greening method, ecological celluar concrete greening method, thick layer base material spraying greening method
Deng；Be generally filling carrier with non-woven fabrics, plastic wire etc. one is raw method of packing up and quitting is planted, filling peat, stalk fibre, fertilizer,
Water-retaining agent and vegetable seeds are not suppressed by compacting or and to form sheet or bag-shaped plant vector, be then attached to slope surface into
Row greening.Although above method obtains certain afforestation effect, easily broken up by rainwater, Gu slope ability is poor, retain water and nutrients ability
Low, not drought-resistant, the later period needs to irrigate, apply fertilizer, and increases cost, and not can guarantee long-term afforestation effect.
