GROUND IMPROVEMENT STRUCTURE AND EXCAVATION METHOD
To provide a ground improvement structure and the like which can suppress work period and cost required for an artificial impermeable layer.SOLUTION: A ground improvement structure includes: earth retaining walls 3 at both sides of an excavation position in a ground 2; and an artificial impermeable layer 4 formed by improving the ground 2 between the earth retaining walls 3 using a solidification material. An upper face of the artificial impermeable layer 4 is a horizontal surface formed in a horizontal direction. A lower face of the artificial impermeable layer 4 includes an upwardly protruding shape. A thickness of the artificial impermeable layer 4 at an intermediate portion between the earth retaining walls 3 is smaller than a thickness at a position of the earth retaining walls 3.SELECTED DRAWING: Figure 5
【課題】人工不透水層にかかる工期やコストを抑えることのできる地盤改良構造等を提供する。【解決手段】地盤改良構造は、地盤２の掘削箇所の両側の山留壁３と、山留壁３の間の地盤２を固化材により改良して形成された人工不透水層４と、を有する。人工不透水層４の上面は水平方向に形成される水平面であり、人工不透水層４の下面は上方に凸となった形状を有し、山留壁３の間の中間部における人工不透水層４の厚さが、山留壁３の位置における厚さより小さい。【選択図】図５
