METHOD OF CONSTRUCTING WALL BODY
PROBLEM TO BE SOLVED: To provide a method of constructing a wall body in which pre-stress in a circumferential direction can be efficiently introduced, and a wall body is fixed when the wall body is completed.SOLUTION: Concrete 80 of a dike 2 is cast while pipes 64a, 64b, sheath tubes 63, 64c, etc., are fitted therein with a perpendicular PC steel material 17a and a perpendicular reinforcing bar 19a extending from a bottom slab 5. A dike bottom part is installed movably while the pipe 64b buried in the concrete 80 is supported by the pipe 64a buried in the bottom slab 5. A rubber plate 66 is arranged between the pipes 64a, 64b. When pre-stress is introduced in a circumferential direction of the dike 2, the whole dike including the bottom part moves inward. Then cement mortar 71 is charged between the dike bottom part and the bottom slab 5 below it and so on. After the cement mortar 71 is hardened, the PC steel material 17a is tensed to introduce perpendicular prestress into the dike 2, and cement milk 73 is charged in the pipes 64a, 64b, rubber plate 66, etc.SELECTED DRAWING: Figure 4
【課題】周方向のプレストレスを効率よく導入できるとともに完成時には壁体が固定される壁体の構築方法を提供する。【解決手段】底版５から延びる鉛直方向PC鋼材１７ａや鉛直方向鉄筋１９ａに、パイプ６４ａ、６４ｂ、シース管６３、６４ｃ等を通した状態で、防液堤２のコンクリート８０を打設する。防液堤底部は、底版５に埋設したパイプ６４ａでコンクリート８０に埋設したパイプ６４ｂを支持して移動可能に配置される。パイプ６４ａ、６４ｂ間には、ゴム板６６が配置される。防液堤２の周方向にプレストレスを導入すると、底部を含む防液堤全体が内側に移動する。その後、防液堤底部とその下方の底版５の間等にモルタル７１を充填する。モルタル７１の硬化後、PC鋼材１７ａを緊張して防液堤２に鉛直方向のプレストレスを導入し、パイプ６４ａ、６４ｂ、ゴム板６６等にセメントミルク７３を充填する。【選択図】図４
