Microorganism induction silty-fine sand consolidating soft soil roadbed ecological improvement method
The invention provides a microorganism induction silty-fine sand consolidating soft soil roadbed ecological improvement method. Microorganism adopts bacillus pasteurii, the strain initially is freeze-dried powder, and bacteria activation and culture are carried out in a culture solution to obtain a concentrated solution of bacillus pasteurii; then silty-fine sand is mixed into soft soil, the mixing ratio of silty-fine sand is 10-20%, and the silty-fine sand provides large-size aggregate for a soft soil road; and the concentrated solution of bacillus pasteurii is mixed into a nutrient solutionand injected into a sandy roadbed, and then a consolidation solution is injected until the roadbed reaches an expected goal. The microorganism induction silty-fine sand consolidating soft soil roadbedecological improvement method applies interdisciplinary subjects, and biochemical technology is used for treating soft soil roadbed, so that the problems of high pollution, high energy consumption and the like of traditional physical and chemical methods for treating roadbeds are solved, the strengthen treatment on the soft soil roadbed can be realized, and the problems of environmental pollutionand energy consumption are reduced.
本发明提供一种微生物诱导粉细砂固结软土路基生态改良方法，其中微生物采用巴氏芽孢杆菌，菌种开始为冻干粉，在培养液中进行细菌活化和培养，得到巴氏芽孢杆菌浓缩液；然后向软土中拌入粉细砂，粉细砂拌和比例在10‑20％，粉细砂为软土路提供大粒径骨料；将巴氏芽孢杆菌浓缩液掺入营养液中注入砂土路基，再注入固结液，直至路基未达到预期目标。本发明应用交叉学科，使用生物化学技术处理软土路基，克服了传统物理和化学方法处理路基的高污染、高能耗等问题，既能实现对软土路基的强化处理，又减少了环境污染和能耗问题。
