description An underground storage tank (10) comprises a cylindrical inner wall (14), a cylindrical outer wall (12) of plastic resin and reinforcement fibers, and a layer of spacer filaments (36) wound around the inner wall (14), the spacer filaments (36) separating the inner (14) and outer walls (12), and the spacer filaments (36) being at least partially surrounded by voids (40) to enable liquids to flow along the filaments (36). Le réservoir de stockage souterrain (10) selon l'invention se compose d'une paroi interne cylindrique (14), d'une paroi externe cylindrique (12) en résine plastique et fibres de renforcement, et d'une couche de filaments intercalaires (36) enroulés autour de la paroi interne (14), lesdits filaments intercalaires (36) séparant la paroi interne (14) et externe (12) et étant entourés au moins partiellement de vides (40) afin de permettre aux liquides de s'écouler le long des filaments.
