Abstract

This item is a prefabricated shelter that is installed on the ground and used as a bunker, general warehouse, or evacuation center. Liner plates, which are constructed by bolting together circumferentially, and H-shaped cross-section reinforcing rings, which are constructed by bolting together circumferentially via coupling plates, are alternately arranged and connected in a series of bolts to form a roughly portal-like tunnel shape with an arched roof. Reinforcing ribs are provided at the left and right base ends of the arch that forms the roof of each reinforcing ring.
