CHEMICAL INJECTION METHOD
To set a direction in which a large amount of chemical is injected in the ground.SOLUTION: A chemical injection method includes: a casing pipe step of drilling the ground G, and building a casing pipe 50; an injection pipe step of deviating shaft centers of the casing pipe and an injection pipe so that an approaching place S is formed where an outer peripheral surface 100A of the injection pipe 100 approaches an inner peripheral surface 50A of the casing pipe 50, and of building the injection pipe 100 in the casing pipe 50; a filling step of filling a grout material 54 into the casing pipe 50; a pull-out step of pulling out the casing pipe 50 after filling the grout material 54; and an injection step of inserting an injection packer 150 into the injection pipe 100 and injecting a chemical 90 into the ground G.SELECTED DRAWING: Figure 2
【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の内周面５０Ａに注入管１００の外周面１００Ａが接近した接近箇所Ｓが形成されるように両者の軸心をずらして、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、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、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を挿入して地盤Ｇへ薬液９０を注入する注入工程と、を備えている。【選択図】図２
