- 補強管を打設するための削孔径と略同等の径を有する第1穿孔部と、その第1穿孔部よりも大径で、それと同心状の第2穿孔部とを有する段付き下孔を地山に形成した後、上記第1穿孔部を延長するようにして該第1穿孔部と略同径の削孔を施すと同時に該削孔内に補強管を打設し、その補強管の後端部外周と上記第2穿孔部の内面との間に水と反応して膨らむ水膨張性粉体を中空筒状の伸縮性袋体内に収容したパッカーからなるシール手段を介在させた後、上記補強管を介して該補強管内およびその周囲の地山内に固結材を充填して地山を補強する地山補強工法であって、
前記パッカーを前記補強管よりも大径のガイド筒体外周面に嵌めた状態で、前記補強管の下孔側の端部と前記第2穿孔部の内面との間に挿入したのち前記ガイド筒体を引き抜き除去することを特徴とする地山補強工法。 - 前記伸縮性袋体が、通水性材料からなる請求項1に記載の地山補強工法。
