Abstract

PROBLEM TO BE SOLVED: To dispose of waste in a stable state. SOLUTION: A solid phase water cut-off bed 3 is formed by mounting a waste vessel 1 in a water cut-off vessel 2 made of a plastic resin and packing a plastic resin in a freely flowing state in the water cut-off vessel 2 so as to cover the periphery and the upper part of the waste vessel 1. After that, the water cut-off vessel 2 is mounted in a pit 4 and a solid phase blocking bed 5 is formed by packing a concrete in a freely flowing state in the pit 4 to cover the periphery and the upper part of the water cut-off vessel 2 and water infiltrating into pit 4 and the blocking bed 5 is suppressed to be brought into contact with the waste vessel 1 by the water cut-off vessel 2 and the water cut-off bed 3.
