VERTICAL SHAFT CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a vertical shaft construction method that reduces depth of an earth retaining wall with a reasonable structure.SOLUTION: A vertical shaft construction method includes the following steps for: constructing an earth retaining wall 3 from above ground, the earth retaining wall having a form corresponding to a tubular form of a vertical shaft; constructing a ground improvement body 5 of a bottomed container form that extends from a location above a bottom edge 3a of the earth retaining wall 3 to a location below the bottom edge 3a, in an area inside the earth retaining wall when seen in a planar view, and having a bottom wall part 5a and a side wall part 5b of a thickness sufficient to withstand ground water pressure and earth pressure, the ground improvement body being constructed by a ground improvement process from above ground; dry-excavating an area A inside the earth retaining wall 3 and above the ground improvement body 5; constructing a permanent bottom plate 7 of the vertical shaft 1 above the ground improvement body 5; and constructing a permanent structure on the permanent bottom plate 7.SELECTED DRAWING: Figure 3
【課題】合理的な構造で土留壁の深度を浅くする立坑構築方法を提供することを目的とする。【解決手段】立坑構築方法は、立坑の円筒形に対応する形状の土留壁３を地上から構築する土留壁構築工程と、平面視で土留壁の内側の領域において当該土留壁３の下端３ａよりも上方の位置から当該下端３ａよりも下方の位置まで延在すると共に、地下水圧及び土圧に耐え得る厚さの底壁部５ａ及び側壁部５ｂを有する有底の容器形状の地盤改良体５を、地上からの地盤改良処理によって構築する地盤改良体構築工程と、土留壁３の内側かつ地盤改良体５の上方の領域Ａをドライ掘削するドライ掘削工程と、地盤改良体５の上に、立坑１の本設底版７を構築する底版構築工程と、本設底版７上に本設構造物を構築する本設工程と、を備える。【選択図】図３
