Abstract

L'invention comprend une structure de contention formée par des profils métalliques normalisés creux ou boulonnés, qui possédent des guides qui facilitent la construction de chaque panneau blindé modulaire qui forme les parois de l'enceinte, par assemblage de planches individuelles construites au moyen d'une structure de type sandwich avec une couche de matériau polymère, une autre de plomb dans les mêmes proportions et une chambre à air comme noyau central. Du fait de sa portabilité, de sa modularité et de sa facilité de montage, elle permet de réaliser des essais n'importe où.
