Description
できる地盤が限定されている。
C6H12O6+6O2→6CO2+6H2O(好気性条件)
C6H12O6→2CO2+2C2H5OH(嫌気性条件)
このとき土壌中に溶解しているカルシウム、あるいは地盤中に注入したカルシウムと微生物の発生した二酸化炭素が反応し、次式のとおり、土粒子間に炭酸カルシウムを析出・沈澱し、地盤を硬化する。
Ca2++CO2 +H2O→CaCO3+2H+
また、本発明により析出するカルシウム塩とは炭酸カルシウム、水酸化カルシウム、塩化カルシウム、硝酸カルシウム等で、注入する微生物や地盤に生息する微生物に影響される。有機栄養源とは微生物の栄養源となるものであり、好ましくは土壌中の微生物によって代謝分解される糖類である。例えば、グルコースやフラクトースなどの単糖類、スクロース、マルトースあるいはガラクトースなどの2糖類、その他のオリゴ糖、でんぷんやマルトデキストリンなどの多糖類、その他糖類を例示することができる。微生物によって、あるいは有機栄養源によって代謝速度が変化するため、施工時地盤によって選択する必要がある。
微生物による炭酸カルシウムの析出実験を行った。
水溶性カルシウムとしては、石灰0.59gを25mlの蒸留水に溶解したものと、貝殻を多く含む地盤300gを採取し、500mlの蒸留水でよく攪拌後、濾過した液25mlの2種類を用意した。
実施例5として1mのプラスチック製モールドに表1の実施例2で使用した貝殻を多く含む地盤を90cm充填(相対密度60%、透水係数2.02×10―2cm/s)し、蒸留水100mlあたりイースト菌2gとグルコース2.8gの割合で作成した薬液1500mlを5サイクル通液し作成した供試体を脱型し10cmに切断後、ラップで密封し28日間養生後の透水係数を測定した。透水試験は地盤工学会基準に準じた加圧透水試験を行った。
また、同様に実施例6として豊浦標準砂(相対密度60%、透水係数1.5×10―2cm/s)に実施例4で用いた石灰水100mlあたりイースト菌2gとグルコース2.8gの割合で作成した薬液1500mlを5サイクル通液し作成した供試体を脱型し10cmに切断後、ラップで密封し28日間養生後の透水係数を測定した。結果を表2に示す。
