COFFERDAM STRUCTURE, CONSTRUCTION METHOD THEREFOR, AND WATERPROOF COVER USED FOR CONSTRUCTION METHOD
To provide a cofferdam structure that makes it possible to prevent a water leak with simple work and to make a liner plate, a main constitutional member, be easy to reuse.SOLUTION: A cofferdam structure 7 constructed around a bridge pier 10 comprises: a cofferdam structure body 7a constructed so as to have a predetermined height around the bridge pier 10; and a waterproof cover 7b that is provided so as to cover an outside surface 7c of the cofferdam structure body 7a and prevents a water leak to the inside of the cofferdam structure body 7a. Preferably, the waterproof cover 7b includes: at least one waterproof sheet 78 arranged along the circumferential direction of the outside surface 7c of the cofferdam structure body 7a; a joint 78a that is formed between sheet ends 78d of the at least one waterproof sheet 78 in the at least one waterproof sheet 78 being arranged on the outside surface 7c; and a waterproof fastener 79 that bonds the joint 78a so as to prevent a water leak from the joint 78a.SELECTED DRAWING: Figure 7
【課題】簡単な作業で水漏れを防止でき、主要構成部材であるライナープレートを再使用しやすくできる仮締切構造体を提供する。【解決手段】橋脚１０の周りに構築される仮締切構造体７であって、橋脚１０の周りに所定の高さになるように構築される仮締切構造体本体７ａと、仮締切構造体本体７ａの外側面７ｃを覆うように設けられ、仮締切構造体本体７ａの内部への漏水を防止する防水カバー７ｂと、を備える。好ましくは、防水カバー７ｂは、仮締切構造体本体７ａの外側面７ｃの周方向に沿って配置される少なくとも１の防水シート７８と、少なくとも１の防水シート７８が外側面７ｃに配置される際に少なくとも１の防水シート７８のシート端部７８ｄ間に形成される繋ぎ目７８ａと、繋ぎ目７８ａからの漏水を防止するように繋ぎ目７８ａを接合する防水ファスナー７９と、を含む。【選択図】図７
