SOIL MODIFYING METHOD AND SOIL MODIFIER USED THEREFOR, AND MODIFIED SOIL
To provide a soil modifying method that does not invite complicated processes, has a small impact on the environment, and has a high ability to reduce liquefaction while enabling reversible use of the ground, and to provide a soil modifier used therefor, and to provide a modified soil.SOLUTION: A microorganism, a nutrient source and a cellulose source are added to the target soil 11 whose main component is earth and sand. The microorganism produces the calcium compound 22 by metabolism. The nutrient source contains at least a calcium and a component used by the microorganism in metabolism. The cellulose source is mainly composed of the cellulose fiber 21, and is entangled to the particle 12 of the earth and sand constituting the modified soil 11 and is precipitated with the calcium compound 22 produced by the microorganism.SELECTED DRAWING: Figure 1
【課題】複雑な工程を招くことなく、環境への負荷が小さく、地盤の可逆的な利用を可能としつつ、液状化を軽減する能力の高い土壌改質方法およびこれに用いる土壌改質剤、ならびに改質土壌を提供する。【解決手段】土砂を主成分とする対象土壌１１は、微生物、栄養源およびセルロース源が添加される。微生物は、代謝によってカルシウム化合物２２を生成する。栄養源は、少なくともカルシウムおよび微生物が代謝で用いる成分を含有する。セルロース源は、セルロース繊維２１を主成分とし改質土壌１１を構成する土砂の粒子１２に絡みつくとともに微生物が生成するカルシウム化合物２２が析出する。【選択図】図１
