WALL BODY CONSTRUCTION METHOD AND WALL BODY
To provide a wall body construction method and the like in which construction can be progressed in a state where a wall body is stable and a construction period can be shortened.SOLUTION: When constructing a dike 2a in a state where an opening 20 remains, a PC steel material 17a in a circumferential direction and a PC steel material 17b in a vertical direction disposed at positions not straddling the opening 20 of the dike 2a and PC steel materials 171, 172 having one end in the opening 20 are tensed, to introduce prestress in the dike 2a. After tension by the PC steel materials 171, 172 is released and the opening 20 is closed, a PC steel material in the circumferential direction and a PC steel material in the vertical direction disposed at positions straddling the closed portion are tensed, to introduce prestress in the dike 2a.SELECTED DRAWING: Figure 3
【課題】壁体が安定した状態で施工を進めることができ、工期も短縮可能な壁体構築方法等を提供する。【解決手段】開口部２０を残した状態で防液堤２ａを構築する際に、防液堤２ａの開口部２０を跨がない位置に配置される周方向PC鋼材１７ａ、縦方向PC鋼材１７ｂと、開口部２０に一端を有するPC鋼材１７１、１７２とを緊張して防液堤２ａにプレストレスを導入する。PC鋼材１７１、１７２による緊張を解除して開口部２０を閉塞した後、閉塞部を跨ぐ位置に配置された周方向PC鋼材、縦方向PC鋼材を緊張して防液堤２ａにプレストレスを導入する。【選択図】図３
