が困難になる。The above cement-based solidifying agent and quicklime-based solidifying agent are usually added in an amount of 10 to 15% by weight with respect to the soil. With such an addition amount, the pH of the treated soil is 1%.
It becomes more than 2 and causes alkali pollution. There is also a problem that it takes a long time to solidify to the extent that it can be transported and transported. Furthermore, there is no danger of alkali pollution with the gypsum-based solidifying agent, and the treated soil solidifies in a short time, but the solidifying agent dissolves and the treated soil collapses when it comes into contact with water, and the soil contains a large amount of water. In this case, there is a risk of causing solidification failure, so it is necessary to add a large amount. Furthermore, there is no danger of alkali pollution even with the organic polymer-based coagulant or water absorbent resin, and the solidification time is short, but the treated soil does not have water resistance, and the treated soil will collapse when contacted with water, In the case of soil containing a large amount of soil, the amount of the organic polymer-based coagulant or water-absorbent resin added increases, and the treated soil becomes an elastic body, making it difficult to dismount or carry it out with heavy machinery.
