TOWER FOUNDATION

摘要

A tower foundation (10) has a base slab (11), pillar slabs (12), and a crown stab (13), all of which are made of precast concrete structures. The slabs are all retained in position by steel guide rods (15) that extend upwardly from the base slab. The guide rods have externally threaded ends (16) configured to receive internally threaded mounting nuts (17). The crown slab has guide rod mounting holes (22) through which the guide rods extend. The crown slab has a central passageway (18) with two semi-circular ancillary channels (19) which include an incoming conduit channel (20) and an outgoing conduit channel (21). The incoming conduit channel receives the incoming electrical conduit (24) while the outgoing conduit channel (21) receives the outgoing electrical conduit (24′).
