Sectional storage tanks.

摘要

A storage tank has side walls (100) each assembled from a plurality of panels (1), preferably of metal clad GRP, interconnected with one another. The panels (1) are each of hyperbolic paraboloid ("hypar") shape thus providing a concave surface (3) which, on assembly of the tank, faces out. The tanks may be strengthened by internal bracing (500) under tension or external bracing under compression.
