FOUNDATION STRUCTURE OF TOWER

摘要

[PROBLEMS] To provide a foundation structure of a tower capable of reducing labor load, construction cost, and production steps by reducing the scale of the structure of a foundation and facilitating construction. [MEANS FOR SOLVING PROBLEMS] This foundation structure of the tower for supporting the main pedestals (4) of the tower comprises main piles (1) installed in the ground along directions roughly matching the directions of the main pedestals (4), auxiliary piles (2) installed in the ground along surface directions connecting the foundations to the center of the tower in plan view, and joining structures (3) joining the main piles (1) to the auxiliary piles (2) and to which the base parts of the main pedestals (4) are fixed. The joining structures (3) are built, for example, by placing a concrete (7) in a steel pipe (6). The top parts of the main piles (1) are joined to the lower surfaces of the joining structures (3), and the top parts of the auxiliary piles (2) are joined to the side faces thereof.
