CHEMICAL INJECTION METHOD
To set a direction in which a large amount of chemical is injected into the ground.SOLUTION: A chemical injection method comprises: a casing pipe process of drilling a hole in the ground G and erecting a casing pipe 50; a filling process of filling a grout material 54 into the casing pipe 50; an injection pipe process of erecting an injection pipe 100 in the casing pipe 50; a pulling-out process of pulling out the casing pipe 50 after filling with the grout material 54; and an injection process of inserting an injection packer 150 into the injection pipe 100, spraying chemical from an injection hole 112 between packer materials 152 above and below the injection packer 150 in the injection pipe 100, and fracturing one side of a grout portion 180 formed by hardening of the grout material 54 to inject the chemical 90 into the ground G.SELECTED DRAWING: Figure 1
【課題】地盤に薬液を多く注入させる方向を設定する。【解決手段】薬液の注入方法は、地盤Ｇを削孔してケーシングパイプ５０を建て込むケーシングパイプ工程と、ケーシングパイプ５０内にグラウト材５４を充填する充填工程と、ケーシングパイプ５０に注入管１００を建て込む注入管工程と、グラウト材５４を充填後ケーシングパイプ５０を引き抜く引抜工程と、注入管１００に注入パッカー１５０を挿入し注入管１００における注入パッカー１５０の上下のパッカー材１５２の間の噴出孔１１２から薬液を噴出しグラウト材５４が硬化して形成されたグラウト部１８０の一方側を破砕して薬液９０を地盤Ｇに注入する注入工程と、を備える。【選択図】図１
