PHC PHC Reinforcement Structure and Method of PHC Pile and PHC Pile having such Reinforcement Structure

摘要

The present invention relates to a structure of reinforcing an upper portion of a prestressed high strength concrete (PHC) pile by the installment of a hollow steel pipe, a method of reinforcing the upper portion of the PHC pile in the field, and a PHC pile having such a reinforcement structure, which are configured to dispose a reinforcing steel pipe in the hollow of the PHC pile at the construction site of the PHC pile to integrate with the PHC pile, thereby increasing flexural strength and shear strength against the PHC pile as quickly as required in the field.
