Prefabricated internal hollow hollow pier pier using corrugated steel pipe and construction method

摘要

PURPOSE: A prefabricated internally confined hollow CFT pier using a corrugated pipe and a construction method thereof are provided to reduce construction costs and time, and to improve buckling strength and shearing strength. CONSTITUTION: A prefabricated internally confined hollow CFT pier using a corrugated pipe comprises column segments(10), a coping part(20), and a foundation part. The column segments are composed of a corrugated pipe, and have hollows and a connecting members(100). A plate with multiple coupling holes is fixed to the corrugated pipe. The coping part comprises a coupling groove(220), a stepped surface(230), and through holes(240). The foundation part comprises a connecting member(300).
