The invention discloses a hard
reinforced concrete revetment slope biological repairing method, which is characterized by comprising the steps of: roughing a concrete
revetment and constructing drainage ditches at set intervals; digging a water collecting tank on one side of the cross of the
revetment and a road, reserving an opening at the joint of the
drainage ditch and the water collecting tank, and constructing a watertight concrete overflow
bank; filling gravels in the water collecting tank and the drainage ditches; and
welding earthwork grids by high-density
polyethylene stripes on the protection slope, laying gravel
cushion coats in the earthwork grids, and finally pouring biological
slurry. The method has the advantages that: the whole project is stable and safe; rain flows into the water collecting tank and passes through grave areas, non-watertight sand-free concrete, a slope
cushion coat,
plant roots and the like to seep into rivers, so
water quality is improved to a relatively large extent; when
rainfall runoff is overlarge, the rain overflows from the overflow
bank and passes through the graves of the drainage ditches, so the
water quality is also purified to a certain extent, meanwhile the slope is protected; the biological
slurry poured onto the slope is prepared from
biological materials, and has certain anti-
erosion strength and can be used as a substrate for
plant growth, so the cost is low and the operation is simple.
