摘要
Posts are made by drilling holes around a perimeter, the exact placement offorms andreinforcement steel within those holes, as well as similarly drilled andformed interior bearingposts, each formed with adequate footings and reinforcement prior to massexcavation, whenpre-formed reinforced concrete parabolic wall panels with optionalwaterproofing andinsulation are placed and fixed between the perimeter posts as the postsuncovered by massexcavation. When excavation reaches a pre-determined depth, beams may be laidbetweenfacing perimeter walls post-to-post across the excavated hole to brace thewalls againstpressures exerted by the earth. Each panel's parabolic curves "outward", witheach layer ofwall-panels mating with the layer below with a pre-designed joint and awatertight seal, alsowith each post, continuing downward until the desired depth is attained, whenwall footingsand lowest floor may be poured.
