PILLAR FOUNDATION STRUCTURE HAVING EXPANDED UPPER PART OF STREET FACILITY AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A pillar foundation structure with an expanded head part for a street facility and a construction method thereof are provided to reduce ground excavation and enable rapid construction by fixing a pillar foundation to the ground using a pile driving technique. CONSTITUTION: A pillar foundation structure(100) with an expanded head part for a street facility comprises a pillar foundation(110), an expanded heat part(130), and a resisting unit(150). The pillar foundation is driven into the ground by a pile driving facility and is connected to the lower end of a pillar to support the pillar. The expanded head part is fixed to the upper outer surface of the pillar foundation to expand the head part of the pillar foundation. The expanded head part resists to load transferred to the pillar foundation through the pillar. The resisting unit transfers torsion load transferred from the pillar to the ground by wind applied to a structure like a road sign.
