Application of nanometer material in calcareous sand foundation
The invention provides application of a nano material in a calcareous sand foundation. The nano material is prepared from nano magnesium oxide, nano metakaolin and nano bamboo charcoal powder. The mass ratio of the nano magnesium oxide to the nano metakaolin to the nano bamboo charcoal powder is 1: (0.4-0.6): (0.1-0.2). The particle size of the nano magnesium oxide is 10 nm to 20 nm. The particle size of the nano metakaolin ranges from 40 nm to 60 nm. The particle size of the nano bamboo charcoal powder is 10 nm to 50 nm. The application method comprises the following steps: mixing the nano material with the cement, adding the mixture into the calcareous sand, uniformly stirring to obtain a mixture, adding the mixture into an excavated foundation pit, and uniformly spraying the bacterial liquid to form the calcareous sand foundation. The bacterial liquid is prepared from bacillus pasteurii and paenibacillus polymyxa. The number ratio of viable bacteria of the bacillus pasteurii to the paenibacillus polymyxa in the bacterial liquid is 1: (0.3-0.5). According to the method, the nanometer material is applied to the calcareous sand foundation, the calcareous sand foundation is completed through the method, the bearing capacity of the foundation is high, and the stability of the foundation is better.
本申请提供纳米材料在钙质砂地基中的应用。所述纳米材料由纳米氧化镁、纳米偏高岭土和纳米竹炭粉组成。所述纳米氧化镁、纳米偏高岭土和纳米竹炭粉的质量比为1:0.4～0.6:0.1～0.2。所述纳米氧化镁的粒径为10nm～20nm。所述纳米偏高岭土的粒径为40nm～60nm。所述纳米竹炭粉的粒径为10nm～50nm。所述应用的方法包括以下步骤：将纳米材料与水泥混合，加入钙质砂中，搅拌均匀，得混合料，将混合料加入挖掘后基坑中，均匀喷洒菌液，形成钙质砂地基。所述菌液由巴氏芽孢杆菌和多粘类芽孢杆菌制得。所述菌液中巴氏芽孢杆菌和多粘类芽孢杆菌的活菌数量比例为1:0.3～0.5。本发明利用纳米材料在钙质砂地基中的应用，采用本发明方法完成钙质砂地基，不但地基承载力较高，而且地基稳定性更加良好。
