Abstract
A spherical storage tank holding gases or liquids which is supported on a rigid concrete foundation in a region of the vertical axis of the tank. There is interposed between tank and foundation a mounting rigidly bonded to both the tank and the foundation having generally elastomeric properties. The mounting consists essentially of a plurality of slabs covering the whole upper area of the foundation, in a spaced array leaving only narrow gaps between the individual slabs. The slabs are thin in relation to their size, and the gaps between the individual slabs are filled with a soft-plastic sealant. Moreover, the foundation consists of an upper part and a lower part, between said upper and said lower part being interposed adjustable resilient pads to allow an adjustment of the upper part in relation to the lower part to correct the position of the upper part if the lower part has been displaced due to ground shock waves, underground cavations or the like. The lower part of the foundation has a surface loading as required to press on the ground soliciting it up to near its plasticity.
