ABSTRACT:
A tower foundation (10) comprises a base slab (11), a plurality of pillar slabs (12), and a crown stab (13). The base slab (11), pillar slabs (12) and crown slab (13) are all retained in position by six steel guide rods (18) that extend upwardly from the base slab (11). The six guide rods (18) have externally threaded ends configured to receive internally threaded mounting bolts (20). The guide rods are arranged in a generally triangular pattern. The pillar slabs are rectangular with their sides being undercut or sloping outwardly from the bottom surface to the top surface, i.e., the sidewalls diverge outwardly as they extend upwardly. The outwardly sloping sidewalls aid in preventing the foundation from tilting over time.
