METHOD FOR FORMING VEGETATIVE COVERED BEDROCK HAVING STEEP SLOPE

摘要

PROBLEM TO BE SOLVED: To form a stable vegetative covered bedrock on the surface of a steep slope by a method wherein a rigid perforated plate having a specified shape is fixed on the steel slope, a charging space is formed between the face of the slope and the rigid perforated plate, a sheet-shaped vessel having water permeability and flexibility is charged, and the vessel is filled with slurry-like vegetation soil. ;SOLUTION: Net cylinders 2 are spread all over in parallel in the vertical direction of the steep slope 1, the upper and lower ends of the net cylinders 2 are fixed by using anchor pins 23, and packing bags 21 are charged into the net cylinders 2 up to bottoms. A delayed fertilizer 22 is charged into each packing bag 21, slurry-like vegetation soil 3 is injected, and filled up to inlets, and the vegetation bedrock is completed. One or a plurality of mixtures of bodies proper to vegetation such as natural soil and sand, artificial soil and sand, back compost, leaf soil, perlite, waste paper, a chemical fertilizer, a soil conditioner, a water retention agent, etc., are used as vegetation soil. Accordingly, the vegetative covered bedrock can be formed without depending upon a large quantity of manpower on the steep slope.;COPYRIGHT: (C)1998,JPO
