Improvement method of expansive soil
The invention discloses an expansive soil improvement method, belongs to the technical field of roadbed and pavement engineering, and aims to treat expansive soil in engineering construction in areas with extensive expansive soil distribution, reduce the damage of the expansive soil to the engineering to a range acceptable by the engineering, and improve the expansive soil improvement efficiency based on the consideration of reducing the influence on the surrounding environment and saving the cost. The physical improvement method is characterized in that sisal fibers and silty soil in the yellow flooding area are used for improving weak expansive soil, and the specific process is as follows: (1) material pretreatment: required expansive soil, silty soil and sisal fibers are selected according to the mass ratio and are respectively dried for later use, the mixing amount of the silty soil accounts for 10-50% of the total mass of the silty soil and the expansive soil, and the mixing amount of the sisal fibers accounts for 10-50% of the total mass of the silty soil and the expansive soil; the mixing amount of the sisal fibers accounts for 0.1-0.5% of the total mass of the silty soil and the expansive soil; (2) uniformly mixing the materials in the step (1) in a mixing container; and (3) carrying out stuffy material treatment on the mixture in the step (2) to obtain the product.
本发明公开一种膨胀土的改良方法，属于路基路面工程技术领域，在膨胀土广泛分布地区的工程建设，都会对膨胀土进行处治，以此将膨胀土对工程的危害降低到工程所能接受的范围，基于减少对周围环境影响和节约成本的考虑，提出了一种膨胀土物理改良方法：即使用剑麻纤维和黄泛区粉砂土改良弱膨胀土，具体过程如下：（1）材料预处理，按照质量比例选取所需的膨胀土、粉砂土、剑麻纤维，分别烘干后备用，所述粉砂土掺量占粉砂土和膨胀土总质量的10~50％，剑麻纤维掺量占粉砂土和膨胀土总质量的0.1~0.5％；（2）在混合容器内，将步骤（1）中的材料拌合均匀；（3）对步骤（2）中的拌合物进行闷料处理，即得。
