Abstract: Resilient support means are provided in the trough of the concrete foundation to receive the fabricated spherical shell. The resilient support means can be constructed so as to deform increasingly and permanently in response to an increasing load of the shell thereon or may be constructed so as to receive a pressurized medium. By determining variations in pressures at the various support means, changes can be affected so as to insure a uniform disposition of the shell on the concrete layer which is back filled into the gap between the shell and foundation.

Abstract: The mounting means for the storage containers consists of an upper strip of stainless steel, a lower strip of ordinary structural steel and connecting posts which are welded between the two strips. The upper end of the posts are formed as fastening bolts for storage containers or are adapted to receive fastening bolts for securing a storage container in place.
