JOINT STRUCTURE OF UNDERGROUND CONTINUOUS WALL, AND CONSTRUCTION METHOD OF UNDERGROUND CONTINUOUS WALL
To make an unexcavated portion unnecessary with a simple structure, to perform a stable construction, to improve construction efficiency, and to decrease construction cost.SOLUTION: A joint structure of an underground continuous wall comprises: a fixed partition plate 11 disposed apart from a joint surface 3a included in a precedent element 1A and adjacent to a following element 1B; a pair of connection plates 12 extending from both ends 11a,11a of the fixed partition plate 11 toward the joint surface 3a side adjacent to the following element 1B; and a movable partition plate 13 separated from the fixed partition plate 11 in a longer direction X1 and provided detachably to each of protruding end portions 12a,12a of the pair of connection plates 12,12; in which the protruding end portions 12a of the pair of connection plates 12,12 are in contact with an excavation side faces 3b facing each other in a wall thickness direction X2 of the precedent element 1A.SELECTED DRAWING: Figure 1
【課題】簡単な構造で堀残し部を不要とすることができ、安定した施工を行うことができ、施工効率の向上を図ることができ、施工コストの低減を図ることができる。【解決手段】先行エレメント１Ａにおける隣接する後行エレメント１Ｂの接合面３ａから離間させて配置された固定仕切り板１１と、固定仕切り板１１の両端１１ａ、１１ａから後行エレメント１Ｂの接合面３ａ側に向けて延びる一対の連結板１２と、固定仕切り板１１から長さ方向Ｘ１に離間するとともに、一対の連結板１２、１２の突出端部１２ａ、１２ａ同士に着脱自在に設けられた可動仕切り板１３と、を備え、一対の連結板１２、１２の突出端部１２ａは、先行エレメント１Ａの壁厚方向Ｘ２に対向する掘削側面３ｂに当接している構成の地中連続壁の継手構造を提供する。【選択図】図１
