TILT-RESTRAINING CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a tilt-restraining construction method for an existing bridge pier directly built in the ground, by which the construction period can be shortened safely at a low cost.SOLUTION: A gravity center position of an existing bridge pier is lowered by removing a part 22 of a forming body that forms the existing bridge pier from a portion above the gravity center of the existing pier, in a range capable of securing required strength. Further, in order to secure the required strength as the existing bridge pier, a reinforcement member 21 is installed for reinforcing the portion where the part of the forming body is removed, and also, the total weight of the reinforcement member is lighter than the total weight of the part 22 of the forming body that is removed. Still further, a weight is fixed to a portion lower than the gravity center of the existing bridge pier before or after removing the part of the forming body.SELECTED DRAWING: Figure 3
【課題】地盤に直接設けられた既設橋脚の、安価で安全な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】既設橋脚の重心よりも上側の部分から、必要な強度を確保できる範囲で、当該既設橋脚を形成する形成体の一部２２を撤去することによって、当該既設橋脚の重心位置を下げる。また当該既設橋脚として必要な強度を確保するために、前記形成体が撤去された部分を補強する補強部材２１を設置し、かつ前記補強部材の総重量は、前記撤去した形成体２２の総重量よりも軽い。また前記形成体を撤去する前または後に、前記既設橋脚の重心よりも下側の部分に、重錘を固定する。【選択図】図３
