ABSTRACT:
An underground shelter for the protection of at least one person, comprising two substantially identical rigid panels which may be assembled together into a tunnel configuration and disassembled by distinct mechanical means arranged so as to permit a joined interfitting of both top parts of both panels, respectively, and a rigid connection between the bottom parts of the latter so that the buried panel may withstand side or transverse forces applied to the panel and resulting from the thrust exerted by the earth layer covering the tunnel.
