Abstract

On effectue dans le sol des forages (3) puis on excave un secteur entre deux forages adjacents (3) à l'aide d'un appareil à scie à fil (9), de manière à réaliser une tranchée (4) par laquelle on introduit un élément d'isolation (5). Un mortier de bentonite est coulé dans les forages (3) et dans la tranchée (4), de manière à réaliser par étanchéité une paroi d'isolation (1). Le sol (T) est excavé à l'aide d'un appareil à scie à fil (9) et d'un appareil de mise en place des éléments d'isolation (10) afin d'obtenir la tranchée (4), tandis que chaque élément d'isolation (5) est tiré dans la tranchée (4). On obtient ainsi une meilleure efficacité pour la réalisation d'une paroi d'isolation (1) et, par ailleurs, l'insertion de l'élément d'isolation (5) dans la tranchée s'effectue facilement et avec précision, améliorant ainsi la précision dans la réalisation de l'ouvrage.
