Document Type and Number:
Japanese Patent JP2014134016
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To facilitate alignment of bolt holes of both plates in a rotary press-in construction method for a steel pipe pile with a blade, in which the pile head plate for being coupled to the coupling plate of an upper structure is welded.SOLUTION: A steel pipe pile 41 (41a) with a blade, in which a pile head plate 51 (51a) is welded, is rotated and pressed in. When rotary press-in is completed, the steel pipe pile is inclined to a position of a steel pipe pile 41b from the steel pipe pile 41a in a vertical position. In the case where a pile center is shifted to a pile center Pb from a pile center Pa of the pile head plate 51a, a coupling bolt hole 511c used to be coupled to a coupling plate of an upper structure is formed centering on the core center Pa, in a pile head plate 51b.
