MANUFACTURING METHOD OF GROUND IMPROVEMENT SOIL, AND GROUND IMPROVEMENT METHOD
To provide a manufacturing method of ground improvement soil including nanofibers mixed with cement-based materials and capable of more effectively and efficiently improving the ground, and a ground improvement method.SOLUTION: A ground improvement soil 1 is prepared by mixing soil 2, water 3, cement 4, and nanofiber 5 in a ground improvement device 9. When carrying out the ground improvement of object ground 7 by using the ground improvement soil that exhibits ground strength equal to or higher than a reference value within a predetermined curing period T after the completion of the mixing, aging data on uniaxial compressive strength of a test samples 6 is obtained in advance using the test samples 6 of the ground improvement soil 1 until the material age exceeds at least the curing period T and a predetermined observation period Ta elapses. The mixing ratio of at least the cement 4 in the ground improvement soil 1 is determined based on the obtained aging data and the reference value of the ground strength.SELECTED DRAWING: Figure 1
【課題】セメント系材料にナノファイバーが混合されていて、より効果的かつ効率的に地盤改良できる地盤改良土の製造方法および地盤改良方法を提供する。【解決手段】土２と水３とセメント４とナノファイバー５とを地盤改良装置９によって混合して、この混合完了後の所定の養生期間Ｔ内に、基準値以上の地盤強度を発現する地盤改良土１を用いて対象地盤７に対して地盤改良を行うに際して、地盤改良土１の試験サンプル６を用いて、材齢が少なくとも養生期間Ｔを超えて所定の観察期間Ｔａ経過時までの試験サンプル６の一軸圧縮強さの経時変化データを予め把握しておき、この把握した経時変化データと地盤強度の基準値とに基づいて、地盤改良土１での少なくともセメント４の配合割合を決定する。【選択図】図１
