Abstract

Le procédé et dispositif ci-décrits visant à assainir les décharges de déchets (10) par la mise en place ultérieure d'une couche imperméable aux liquides, fonctionnent tant selon le principe du travail au bouclier que selon la méthode de la taille, le dispositif d'avancement se présentant sensiblement sous la forme d'une unité rectangulaire. Les plaques de couverture (2) recouvrant les plaques de base (3) sont reliées les unes aux autres par des vérins hydrauliques (16). Un étançon de face (29) situé l'avant et un bouclier-support (17) situé sur la face arrière forment un tunnel entièrement clos, qui progresse sous la décharge (10) de manière articulée et par cuvelage et sous la protection duquel il est possible d'incorporer des soles d'étanchéité. Le matériau abattu au-dessous de la taille est transporté derrière le bouclier-support (17) où il est compacté, grâce à quoi les dispositifs individuels, étayés par des vérins de traction (18), progressent pas à pas et par cycle.
