CLEANING EQUIPMENT FOR CONTAMINATED SOIL

PROBLEM TO BE SOLVED: To provide cleaning equipment for contaminated soil which has a satisfactory strength without the risk of destruction, can easily change an installation site and, moreover, allows a boundary wall having high water-shielding property of a contact part with a floor surface to be disposed at a place boundary between raw soil and cleaned soil. SOLUTION: The cleaning equipment for contaminated soil is composed of three yards of a raw soil yard, a cleaning yard and a cleaned soil yard, wherein an outflow prevention bank is disposed on an outer peripheral part of each yard and a boundary wall constituted by arranging or piling a plurality of cuboidal blocks is installed on the boundary between the raw soil yard and the cleaned soil yard, which are adjacent to each other and, when orthogonal three edges of the cuboidal block are respectively a, b, c, lengths of the edges a, b, c satisfy the relation: a≥b≥c and the boundary wall is constituted such that the edge c becomes the height direction of the cuboidal block and a height of the disposed boundary wall is 2.5 times or less of the length of the edge b.
