<p><P>PROBLEM TO BE SOLVED: To facilitate removal and recovery of soil near ground surface having high contamination concentration in the decontamination of radioactive contaminated ground. <P>SOLUTION: The soil removing method uses a weeding, root-cutting and soil-loosening apparatus comprising a rotary cutter 1 to be thrust into the surface layer of soil and cut the root in the surface layer and loosen the soil, and a crawler-type vehicle 2. The apparatus is traveled on the contaminated soil while rotating the rotary cutter 1 in a manner to contact the lower end of the cutter with soil at a preset depth of the surface layer of the contaminated soil to cut the root and loosen the soil in the surface layer to the preset depth of the surface layer and, when weed is thickly grown on the ground, the weeding of the weed is also performed by the rotary cutter 1 simultaneously. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
