The invention relates to a biological
brick for ecological slope protection of
rock slope surface and a preparation method and a construction method thereof. The biological
brick for ecological slope protection is a hexagonal
brick pressed by specially-prepared base materials, and the surface of the brick is provided with a notch groove and a pit. The biological brick for ecological slope protection consists of two
layers, wherein, one layer is a
nutrition medium layer, and the other layer is a seed planting layer; the biological brick for ecological slope protection has the characteristics of light
mass, air permeability, water and
fertilizer reservation, rainwater
erosion and soak resistance, rich
nutrition and so on, a seed can directly sprout from the
surface layer of the biological brick, and a brick body is also ideally suitable for the growth of a
plant. The base materials of the
nutrition medium layer of the biological brick consists of biological
sludge drying organic
compost, fine
loam, turfy soil, compound
fertilizer,
water retention agent,
cement and pH modifier. The construction method for the biological brick on a
rock slope comprises slope trimming, biological hexagonal brick pavement,
anchor bolt driving, net suspension, covering and maintenance. The biological brick is provided with the
plant seed planting layer, can be quickly molded at one-time construction to restore the
vegetation; compared with other
rock slope greening methods, the construction method has the characteristics that: the construction method has simple construction and does not need large-scale
mechanical equipment, and the construction cost is two thirds of that of the prior guniting slope protection, etc.
