CONCRETE WALL STRUCTURE FOR REINFORCING FILL-INTEGRATED BRIDGE, AND CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To enable tensile stress of a girder to become lower than ever, while keeping girder height low, and enable an improvement in workability.SOLUTION: A concrete wall structure is constructed by a step of integrally providing an abutment 4 on a side surface of reinforcing fill 2, a step of loading an end 3a of a PC bridge girder 3 on a girder joint 42 of the abutment 4, and a step of forming a joint 7 positioned in an upper part of the abutment 4 in the state of separation from reinforcing fill 2, in a predetermined area between the PC bridge girder 3 and the reinforcing fill 2.SELECTED DRAWING: Figure 2
【課題】桁高を抑えつつ、従来よりも桁の引張り応力を小さくすることができるうえ、施工性を向上させることができる。【解決手段】補強盛土２の側面に、橋台４を一体的に設ける工程と、橋台４の桁接合部４２の上にＰＣ橋桁３の端部３ａを載置させる工程と、ＰＣ橋桁３と補強盛土２との間の所定領域に、補強盛土２から分離させた状態で橋台４上部に位置する接合部７を形成する工程と、によって施工されたコンクリート壁構造を提供する。【選択図】図２
