To develop a method of removing an earth retaining member without causing ground settlement in a periphery such as an adjacent ground, in a place having a high risk of settlement of a peripheral ground when an earth retaining member such as a sheet pile is removed in a weak ground.SOLUTION: A removing method of an earth retaining wall comprises: a reinforcement layer forming step of inserting an injection pipe into a ground along an earth retaining wall, and injecting a ground hardener into a ground between an adjacent boundary and a wall face of the earth retaining wall through the injection pipe; a step of, after pulling out one or more core materials or steel sheet piles constituting the earth retaining wall, filling a cement filler into void portions in the ground where the pulled-out core material or steel sheet pile wall is placed.SELECTED DRAWING: Figure 1
【課題】軟弱地盤において、シートパイルなどの山留部材を撤去すると、周囲の地盤が沈下する危険性が高い箇所において、隣地など周囲に地盤沈下を及ぼさずに山留部材を撤去する方法を開発する。【解決手段】山留壁に沿わせて地盤内に注入管を挿入させ、当該注入管より隣接境界線と当該山留壁の壁面との間の地盤に地盤硬化剤を注入する補強層形成工程と、前記山留壁を構成する芯材、または鋼製矢板を一本、あるいは複数本引き抜いた後に、セメント系充填剤を引き抜かれた当該芯材または当該鋼製矢板壁が建て込まれていた地盤内の空洞部に充填する工程と、を含む山留壁の撤去方法。【選択図】図１
