Method for inducing carbonate precipitation through microorganisms combined with rubber material
The invention discloses a method for inducing carbonate precipitation through microorganisms combined with a rubber material. The method comprises the following steps that (1) rubber particles are evenly and dispersedly added into sand, and the sand with the added rubber particles is obtained, wherein the volume of the rubber particles accounts for 1%-30% of that of the sand with the added rubberparticles; and (2) a bacteria solution and a bacteria nutrient solution are poured into the sand with the added rubber particles alternately at intervals. According to the method, the rubber particlesof specific particle sizes are used as additives and are combined with microorganism induced calcium carbonate precipitation technology to treat the sand, and liquefaction resistance of the sand is improved effectively. A test result also verifies that MICP solidification doping rubber calcareous sand has a large damping ratio, and therefore the condition that the sand serves as a basic shock insulation system becomes possible.
本发明公开了一种微生物联合橡胶材料诱导碳酸盐沉淀的方法。包括以下步骤：(1)将橡胶颗粒均匀分散添加到砂土中，获得添加有橡胶颗粒的砂土；其中橡胶颗粒的体积占所述添加有橡胶颗粒的砂土体积的1‑30％；(2)向添加有橡胶颗粒的砂土中交替间隔灌注菌液和菌营养液。本发明通过利用特定粒径的橡胶颗粒作为添加物，结合微生物诱导碳酸钙沉淀技术对砂土进行处理，有效地提高砂土的抗液化性能。试验结果也验证了MICP固化掺橡胶钙质砂有着较大的阻尼比，这使其作为基础隔震体系成为可能。
