CONSTRUCTION METHOD OF LARGE DIAMETER PILE IN WATER AND GUIDE STRUCTURE FOR THE SAME

摘要

Disclosed is a construction method of a large-diameter pile foundation on water, which comprises steps of: (a) arranging a guide structure having a guide unit which corresponds to an intended construction spot of a large pile foundation to form a circular strip area by multiple holes continuously formed by overlapping each other on one side of a barge; and (b) forming a circular strip-shaped excavation hole corresponding to the circular strip area by excavation units of excavation equipment inserted in the holes. The guide structure includes multiple fixating units connecting and fixating an inside part and an outside part within the circular strip area in order to prevent the inside part and the outside part from being separated from each other with respect to the circular strip area.
