Method for solidifying granite residual soil
The invention provides a method for solidifying granite residual soil. The method comprises the following steps: providing bacillus; and sequentially pouring the bacillus, the fixing agent and the cementing liquid into the granite residual soil, wherein the bacillus is selected from one or more of seawater bacillus, bacillus aryabhattai and soil bacillus. According to the method for solidifying the granite residual soil, the granite residual soil is poured with three kinds of bacterial liquid of bacillus capable of producing urease screened from the nature, so that the solidified granite residual soil with high uniaxial compressive strength is formed. According to the method, loose sand grains can be quickly and efficiently bonded together, so that the strength of the foundation sandy soil is improved; in addition, the strains used in the invention are separated from the nature, and the strains do not cause pollution to the natural environment.
本发明提供了一种固化花岗岩残积土的方法。所述方法包括如下步骤：提供芽孢杆菌；以及向花岗岩残积土中依次灌入所述芽孢杆菌、固定剂和胶结液；其中，所述芽孢杆菌选自海水芽孢杆菌、阿氏芽孢杆菌和土壤芽孢杆菌中的一种或多种。本发明的固化花岗岩残积土的方法，采用从自然界筛选得到的三种能够产脲酶的芽孢杆菌的菌液，对花岗岩残积土进行灌注，使之形成单轴抗压强度较高的固化花岗岩残积土。该方法能够快速、高效地将松散的沙粒粘在一起，从而提高地基沙土的强度；此外，本发明使用的菌株是从自然界中分离得到，这些菌株不会对自然环境造成污染。
