BRIDGE PIER CONSTRUCTION METHOD

To provide a bridge pier construction method capable of reducing the construction period for bridge construction.SOLUTION: A plurality of panel members 30 are prepared which are comprised of precast concrete having an outer panel 34, an inner panel 35, and a connecting panel 36, and integrated with a reinforcing bar 38 (step ST1); the plurality of panel members 30 are disposed along the outline of a column body part 8 with a gap 41 opened at least in one place of a circumferential direction (step ST12); concrete is placed in a closed space 37 being the part other than the place with the gap 41 provided (step ST14); a column body intermediate body 48, being in an unfinished state, of the column body part 8 and having the gap 41 extended upward is constructed by repeating above step (step ST2); a column head 9 is constructed on the column body intermediate body 48 (step ST3); the gap 41 of the column body intermediate body 48 is filled to complete the column body part 8 (steps ST4 and ST7).SELECTED DRAWING: Figure 9 【課題】橋梁工事の工期を短縮できる橋脚の構築方法を提供する。【解決手段】外側パネル３４、内側パネル３５及び連結パネル３６を有し、鉄筋篭３８が一体化されたプレキャストコンクリートからなる複数のパネル部材３０を用意し（ステップＳＴ１）、柱本体部８の輪郭に沿って且つ少なくとも周方向の１箇所に隙間４１を空けて、複数のパネル部材３０を並べ（ステップＳＴ１２）、隙間４１が設けられた部分以外の閉空間３７にコンクリートを打設し（ステップＳＴ１４）、これを繰り返して、隙間４１が上方へ延長された、柱本体部８の未完成状態である柱本体中間体４８を構築し（ステップＳＴ２）、柱本体中間体４８の上に柱頭部９を構築し（ステップＳＴ３）、柱本体中間体４８の隙間４１を間詰めして柱本体部８を完成させる（ステップＳＴ４、ＳＴ７）。【選択図】図９
