GROUND IMPROVEMENT METHOD USING STEEL SLAG AND GROUND CONSTRUCTION METHOD USING STEEL SLAG
PROBLEM TO BE SOLVED: To provide a ground improvement method using steel slag and a ground construction method using steel slag which can efficiently improve a ground even in the ground that is not suitable for compaction.SOLUTION: The present invention comprises a first step of preparing a slag mixture by mixing and stirring soil improvement object soil, steel slag adjusted to a predetermined particle diameter width that was sprinkled on an upper surface of the soil improvement object soil, and binder dispersed on an upper surface of the steel slag while adding an impact force to grind the steel slag and a second step of compacting the slag mixture.SELECTED DRAWING: Figure 1
【課題】締固めに適さない地盤であっても、効率よく改良することの可能な、製鋼スラグを用いた地盤改良工法および製鋼スラグを用いた地盤構築工法を提供する。【解決手段】地盤改良対象土と、該地盤改良対象土の上面に撒き出された、所定の粒径幅に調整された製鋼スラグと、該製鋼スラグの上面に散布された結合材とを、前記製鋼スラグに摩砕する程度の衝撃力を加えつつ混合撹拌し、スラグ混合物を作製する第１の工程と、該スラグ混合物を締固める第２の工程と、を備える。【選択図】図１
