PILE HEAD JOINT PART DESIGN METHOD, CONSTRUCTION METHOD, DESIGN DRAWING, SPECIFICATION FOR PILE HEAD ANCHOR REINFORCEMENT, AND PILE HEAD ANCHOR REINFORCEMENT ATTACHMENT POSITION CHECKING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a pile head joint part design method and the like, for making a bending moment generated at a pile head be equal to or lower than an allowable bending moment of a pile head joint part determined by considering attachment intervals of anchor reinforcements even when the intervals of the anchor reinforcements are uneven in the circumferential direction of the pile head.;SOLUTION: A pile head joint part design method includes: an allowable bending moment data preparation step of preparing allowable bending moment data corresponding to an allowable bending moment of a pile head joint part; a generated bending moment calculation step of calculating a generated bending moment Mo generated at the pile head; and a specification determination step of determining a specification for the pile head joint part so that the generated bending moment Mo is equal to or lower than the allowable bending moment data. Allowable bending moment data in the case that attachment intervals of a plurality of anchor reinforcements in the circumferential direction of the pile head are uneven is prepared. As an attachment condition for the plurality of anchor reinforcements, an allowable deviation amount from reference positions for attachment positions of the plurality of anchor reinforcements to the pile head part is determined, where the reference positions are attachment positions in the case that the plurality of anchor reinforcements are attached at equal intervals in the circumferential direction of the pile head.;SELECTED DRAWING: Figure 16;COPYRIGHT: (C)2019,JPO&INPIT
