- 微細気泡供給手段により微細気泡が供給された微細気泡入り流動化処理土を地中に充填して微細気泡が混入した固化処理土を得る造成工法であって、該微細気泡供給手段が、起泡剤の使用を伴わないマイクロバブル発生装置又は超音波発振装置であり、該流動化処理土中の微細気泡は最大気泡直径が50μmであり、最頻値における気泡の直径が10〜50μmであることを特徴とする軽量固化処理土の造成工法。
- 前記微細気泡入り流動化処理土は、泥土に微細気泡を供給し、該微細気泡入り泥土とセメント系固化材又はセメント系固化材含有スラリーを混合し攪拌して得られることを特徴とする請求項1記載の軽量固化処理土の造成工法。
- 前記微細気泡入り流動化処理土は、セメント系固化材含有スラリーに微細気泡を供給し、該微細気泡入りセメント系固化材と泥土を混合し攪拌して得られることを特徴とする請求項1記載の軽量固化処理土の造成工法。
- 前記微細気泡入り流動化処理土は、泥土とセメント系固化材含有スラリーの混合物に微細気泡を供給して得られることを特徴とする請求項1記載の軽量固化処理土の造成工法。
- 微細気泡供給手段により微細気泡が供給されたセメント系固化材含有スラリーを予め製造し、次いで回転軸の下方に放射状に設けた1以上の攪拌翼の回転域の地盤中に、回転軸の所定の位置に付設された固化材吐出管口から当該微細気泡入りセメント系固化材含有スラリーを吐出させ、原位置土と攪拌混合して軽量固化処理土を得る造成工法であって、該微細気泡供給手段が、該微細気泡供給手段が、起泡剤の使用を伴わないマイクロバブル発生装置又は超音波発振装置であり、該セメント系固化材含有スラリー中の微細気泡は最大気泡直径が50μmであり、最頻値における気泡の直径が10〜50μmであることを特徴とする軽量固化処理土の造成工法。
