CIRCULAR BASEMENT

摘要

PROBLEM TO BE SOLVED: To easily and inexpensively provide a circular basement capable of being constructed by a unit structure by means of circular arc precast concrete manufactured under quality control at a factory without necessitating a large-scale construction machine in a short period of time. SOLUTION: Circular arc precast concrete 1 is joined to form a short cylindrical body 1a. The short cylindrical bodies are piled up at several stages to constitute a cylindrical underground skeleton 2. A rectangular room 7 is partitioned and formed inside it to form storage cabinets 11 between outer peripheral faces of the room 7 and the underground skeleton 2.
