摘要

The present invention relates to a steel composite hybrid pile and a construction method thereof. The steel composite hybrid pile of the present invention comprises: a steel pipe pile; concrete filling the inside of the steel pipe pile with a strength of 20-80 Mpa; a bottom end finish plate welded on the bottom end unit of the steel pipe pile for the steel pipe pile and the concrete to make a complete composite behavior; a top end unit finish plate combined with the top end unit of the steel pipe pile for the steel pipe pile and the concrete to make a complete composite behavior; and, a steel pipe band fixated on the top end unit finish plate by a high-tension bolt and connected to the steel pipe pile.
