Nuclear explosion shelter in private garden - has concrete components fed to ground hole by crane, with earth covering

摘要

Protection from pressure waves, heat rays and radioactive radiation from nuclear weapons, are esp. provided by a private shelter area. Horizontal conveyor assemblies, such as conveyor belts, or leads on the arm of a crane, spanning gardens, fences and other obstacles, are used to assist in excavating a pit in a plot of ground. In a sunken position below the ground surface, a compact protective interior comprising concrete components handled by a crane is assembled. Earth is then heaped up, to the level of the interior ceiling slab. Construction and installation are economical.
