CONSTRUCTION METHOD OF UNDERGROUND CONTINUOUS WALL, AND UNDERGROUND CONTINUOUS WALL
PROBLEM TO BE SOLVED: To provide a construction method of an underground continuous wall that facilitates construction of the underground continuous wall.SOLUTION: A strip-shaped excavation groove 117 is formed in a ground in a circumferential direction of an underground continuous wall, leaving a prescribed interval. A preceding element 111a is constructed in the excavation groove 117. Then, the excavation groove 117 is formed between the preceding element 111a and the preceding element 111a constructed separately from each other, and a following element 113 is constructed in the excavation groove 117. The preceding element 111a is constructed by inserting a cylindrical precast block 1 having a hollow part in a stable liquid of the excavation groove 117 while vertically connecting the precast blocks, and then casting concrete inside.SELECTED DRAWING: Figure 2
【課題】地中連続壁を容易に構築できる地中連続壁の構築方法等を提供する。【解決手段】地盤に、地中連続壁の周方向に所定の間隔を空けて離間した短冊形の掘削溝１１７を形成する。そして、当該掘削溝１１７に先行エレメント１１１ａを構築する。その後、離間して構築された先行エレメント１１１ａと先行エレメント１１１ａの間に掘削溝１１７を形成し、当該掘削溝１１７に後行エレメント１１３を構築する。先行エレメント１１１ａは、中空部分を有する筒状のプレキャストブロック１を上下に連結しつつ掘削溝１１７の安定液中に挿入し、その内側にコンクリートを打設して構築される。【選択図】図２
