CHEMICAL GROUTING DEVICE AND GROUND GROUTING METHOD
To provide a chemical grouting device to securely improve the ground in a short duration without forming cleavage in the ground.SOLUTION: A chemical grouting device of the present invention comprises: a grouting external pipe having a plurality of chemical discharge ports for discharging a chemical; and a grouting internal pipe inserted into the grouting external pipe. The grouting internal pipe comprises: a plurality of packer mechanisms having two expandable packer rubbers arranged at predetermined intervals and a discharge port arranged between the two packer rubbers for discharging the chemical; and an adjustable member arranged between two adjacent packer mechanisms among the plurality of packer mechanisms and capable of adjusting an interval between a discharge port arranged on one packer mechanism of the two adjacent packer mechanisms and a discharge port arranged on the other packer mechanism.SELECTED DRAWING: Figure 2
【課題】地盤を割裂させることなく、短期間で確実な地盤改良を行う。【解決手段】本発明の薬液注入装置は、薬液を吐出する薬液吐出口を複数有する注入外管と、前記注入外管に挿入される注入内管と、を有する薬液注入装置において、前記注入内管は、所定間隔を空けて設けられた膨張可能な２つのパッカーゴムと、前記２つのパッカーゴムの間に配置され前記薬液を吐出する吐出口と、を有する複数のパッカー機構と、前記複数のパッカー機構のうち、隣り合う２つのパッカー機構の間に設けられ、前記隣り合う２つのパッカー機構のうちの一方のパッカー機構に設けた吐出口から、他方のパッカー機構に設けた吐出口までの間隔を調整可能な調整部材と、を有することを特徴とする。【選択図】 図２
