TILT-RESTRAINING CONSTRUCTION METHOD AND BRIDGE PIER
PROBLEM TO BE SOLVED: To provide a tilt-restraining construction method for making an existing bridge pier directly built in the ground difficult to be tilted, by which construction can be operated safely at a low cost and the construction period can be shortened.SOLUTION: A tilt-restraining construction method is provided, for making an existing bridge pier 10 directly built in the ground difficult to be tilted, in which resistance means R is attached to the existing bridge pier 10, and when external force that generates a moment acting toward tilting direction of the existing bridge pier 10 is applied to the existing bridge pier 10, the resistance means R is capable of generating resistance force in a direction of cancelling the moment.SELECTED DRAWING: Figure 2
【課題】地盤に直接設けられた既設橋脚を転倒しにくくする転倒抑制工法であって、安価で安全な施工が可能であり、かつ、工期の短縮化が可能な転倒抑制工法を提供する。【解決手段】地盤に直接設けられた既設橋脚１０を転倒しにくくする転倒抑制工法であって、既設橋脚１０を傾斜させようとするモーメントを発生させる外力が当該既設橋脚１０に対して作用したときに当該モーメントを打ち消す方向の抵抗力を生じさせることが可能な抵抗手段Ｒを、既設橋脚１０に取り付けるように構成されている。【選択図】図２
