BUNKER CONSTRUCTION

摘要

A bunker construction is comprised of precast arch elements which form a semicircular roof of the bunker by en-gaging cast-in-place footings. A front and back plate cover the front and back of t he enclosure defined by the arch elements. A crown element along the apex of the arch and footing blocks at the bottom sides of the arch along the footing facilitate a lightning protection system. Precast concrete panels form lateral sides of the front o f the bunker construction and compacted earth coacts with steel stabilizing elements associated with the precast panels and the front plate of the bunker. The entire bunker exterior is covered with compacted earth thereby forming a bunker construction with enhanced structural integrity due to the mechanically stabilized earth in combination with the precast arch elements and front panel members.
