CONTINUOUS UNDERGROUND WALL AND METHOD FOR CONSTRUCTING CONTINUOUS UNDERGROUND WALL
To provide a continuous underground wall that can be easily constructed and can prevent damage to a joint surface of a preceding element, and a method for constructing the continuous underground wall.SOLUTION: A preceding element 2 (first element) has a first concrete portion 23 and a corrugated steel plate 5 provided over the entire wall height direction along an end portion of the first concrete portion 23 on a trailing element 3 side. In the corrugated steel plate 5, a ridge 526 projecting in a wall length direction in which the preceding element 2 and the trailing element 3 are adjacent to each other and extending in a wall thickness direction and a recess 525 recessed in the wall length direction and extending in the wall thickness direction are alternately arranged in a wall height direction, and the first concrete portion 23 is fixed on the surface on the first concrete portion 23 side. The trailing element 3 (second element) has a second concrete portion 33 that is fixed on the surface of the corrugated steel plate 5 on the trailing element 3 side, and further has a box-shaped protective member 6 temporarily provided so as to contact and cover the corrugated steel plate 5 from the trailing element 3 side.SELECTED DRAWING: Figure 4
【課題】容易に施工することができるとともに、先行エレメントの継手面の損傷を防止できる連続地中壁および連続地中壁の施工方法を提供する。【解決手段】先行エレメント２（第１エレメント）は、第１コンクリート部２３と、第１コンクリート部２３における後行エレメント３側の端部に沿って、壁高さ方向全体にわたって設けられた波形鋼板５と、を有し、波形鋼板５は、先行エレメント２と後行エレメント３が隣接する壁長さ方向に突出し、壁厚さ方向に延びる凸条部５２６と、壁長さ方向に凹み、壁厚さ方向に延びる凹条部５２５と、が壁高さ方向に交互に配列されるとともに第１コンクリート部２３側の面に第１コンクリート部２３が定着し、後行エレメント３（第２エレメント）は、波形鋼板５の後行エレメント３側の面と定着する第２コンクリート部３３を有し、波形鋼板５を後行エレメント３側から接触して覆うように仮設される箱状の保護部材６をさらに有する。【選択図】図４
