Claims (5)
- 土壌中の微生物によって代謝分解される有機栄養源と、カルシウム塩と、pH緩衝剤を地盤中に注入し、微生物の代謝分解により地盤中に炭酸ガスを発生させ、該炭酸ガスとカルシウム塩の反応により、地盤中の空隙や不連続な境界部分に炭酸カルシウムを析出させることを特徴とする地盤改良工法。
- 有機栄養源は、土壌微生物によって代謝分解される糖類である、請求項1記載の地盤改良工法。
- カルシウム塩は、炭酸カルシウム、水酸化カルシウム、塩化カルシウム、および硝酸カルシウムよりなる群から選ばれる1種以上である、請求項1または請求項2記載の地盤改良工法。
- 土壌中の微生物によって代謝分解されて炭酸ガスを発生させる有機栄養源と、該炭酸ガスと反応により炭酸カルシウムを析出させるカルシウム塩と、pH緩衝剤を含む、請求項1記載の工法に使用するためのグラウト。
- pHが6〜10に保持された水溶液の形態である、請求項4記載のグラウト。
