PILE PIER EXECUTION METHOD AND PILE PIER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To enhance pile driving precision in pile pier execution and contrive cost reduction. SOLUTION: The main girder 1 of a pier incomplete part previously setting a pipe for pile head fixing 4 is projected from a pier complete part in the form of a cantilever, and the direction and angle of the main girder 1 or a distortion state are adjusted and held so as to near a complete state by tension-adjusting a wire material 2 spanned between the projection edge part of the main girder 1 and the pier complete part so as to be in parallel with the main girder 1. Thereby the position of the pipe for the pile head fixing 4 attached to the main girder 1 is neared to the complete state, a pipe-like pile 5 is driven through the pipe for the pile head fixing 4. In addition, kinds of parts are reduced and cost reduction is contrived in response to the angular change of the main girder 1 and the pipe for the pile head fixing by connecting a traverse girder 3 and the main girder 1 attaching the pipe for the pile head fixing 4 by a duplex tube mechanism rotatable in the circumferential direction.
