Method for reinforcing loess through combination of rubber particles and EICP
The invention discloses a method for reinforcing loess through combination of rubber particles and EICP, and relates to the technical field of building materials.The method for reinforcing loess through combination of rubber particles and EICP comprises the following steps that S1, the address of yellow soil is selected, and the selected yellow soil is dried and smashed; s2, adding rubber particles into the crushed yellow soil, uniformly mixing, then adding a urease solution and a cementing liquid, and uniformly mixing to obtain pre-improved loess; and S3, the pre-improved loess is backfilled in a layered mode, tamped and covered with a thin film, and maintenance is conducted for 1-3 days. The urease solution comprises urease and water, and the urease is selected from one of beans; the cementing liquid comprises urea, calcium chloride and water. According to the method for reinforcing the loess through the combination of the rubber particles and the EICP, more adsorption sites are provided for calcium carbonate precipitation, the calcium carbonate precipitation generated in the loess is more uniform, and therefore the overall reinforcing effect of the loess is improved.
本申请公开了一种橡胶颗粒联合EICP加固黄土的方法，涉及建筑材料技术的领域，一种橡胶颗粒联合EICP加固黄土的方法，包括以下步骤：S1：黄土壤的地址选取，将选取的黄土壤进行干燥、粉碎处理；S2：将粉碎处理的黄土壤中添加橡胶颗粒，混合均匀，再加入脲酶溶液和胶结液，混合均匀，得到预改良黄土；S3：将预改良的黄土分层回填、夯实，覆盖薄膜，养护1~3天后，即可；所述脲酶溶液包括脲酶和水，所述脲酶来自于豆类的一种；所述胶结液包括尿素、氯化钙和水。本申请橡胶颗粒联合EICP加固黄土的方法，不仅为碳酸钙沉淀提供了更多吸附位点，还使得黄土中生成的碳酸钙沉淀更加均匀，从而提高了黄土的整体加固效果。
