Abstract

L'invention concerne un système et un procédé d'assainissement d'un sol contaminé retiré d'un endroit. Le sol contaminé est placé sous plusieurs couches de conduites de chauffage perforées formant une cellule d'assainissement et toute la cellule est recouverte d'une construction légère à toiture cintrée en acier galvanisé afin d'éviter la fuite de vapeurs de la cellule du sol. L'air chauffant introduit dans les conduites de chauffage chauffe le sol contaminé ce qui a pour effet de créer une zone de pression différentielle autour des conduites de chauffage. Ceci se traduit par le migration de contaminants et d'humidité volatilisés à travers les perforations pratiquées dans les parois des conduites et dans la zone de pression plus basse se trouvant dans les conduites en acier chauffées, ce qui pousse les contaminants en provenance du sol vers un système de traitement des effluents gazeux.
