REVEGETATION METHOD AND SURFACE SOIL SAMPLING DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To mechanize surface soil sampling work or restoration work for surface soil to a revegetation area by sucking surface soil from surface soil sampling land near the face of slope for revegetation and then taking in the soil in a mixer tank and by spraying the surface soil to the face of slope for revegetation after mixing adequate fertilizer, soil amendment agent or bonding agent together in conformity with the characteristics of the surface soil sampled. ;SOLUTION: Surface soil of a surface soil sampling area 8 near a face of slope 9 to be revegetated is sampled by a surface soil sampling device 6 after switching a compressor 2 to suction side and is transported to a mixer tank 3 through a hose 4. Next, adequate fertilizer, soil amendment material and bonding agent are mixed together in conformity with the characteristics of surface soil sampled. Then, after switching the compressor 2 to the spray side, the surface soil in the mixer tank 3 is sprayed to the face of slope 9 to be revegetated by a surface soil spraying member 7 through a hose 5. By doing this, the sampling and spraying of the surface soil can be performed easily, by which the labor cost can be reduced, costs for seeds and borrowed earth can be eliminated by utilizing the resources on the job site thereby reducing the construction cost.;COPYRIGHT: (C)1999,JPO
