Title
(EN) CONTAMINATION DIFFUSION PREVENTING STRUCTURE IN CONTAMINATED AREA
(FR) STRUCTURE DE PREVENTION DE DIFFUSION DE CONTAMINATION DANS UNE ZONE CONTAMINEE
Abstract
(EN) A contamination diffusion preventing structure in a contaminated area capable of effectively preventing harmful substances from diffusing to an uncontaminated soil side at a low cost with a rather simple structure and without requiring large-scale equipment, wherein wall bodies (1) for prevention of contamination diffusion are buried in the ground to divide contaminated soil (2) from uncontaminated soil (3), and the wall bodies (1) are formed of a wall material having water permeability and carrying rare-earth compounds.
(FR) L'invention concerne une structure de prévention de diffusion de contamination dans une zone contaminée, en mesure d'éviter de manière efficace, à faible coût, que des substances nocives ne se diffusent à la surface d'un sol non contaminé, avec une structure relativement simple et sans requérir d'équipement important. Des corps de paroi (1) pour éviter que la contamination ne se diffuse sont enfouis dans le sol afin de séparer le sol contaminé (2) du sol non contaminé (3). Les corps de paroi (1) sont réalisés dans un matériau perméable à l'eau et portant des composés du groupe des terres rares.
