Expansive soil improver and improvement method
The invention relates to an expansive soil improver and an improvement method. The expansive soil improver comprises a polycarbonate resin-based suspension, a polyurethane adhesive and hydrophobic magnetic ionic liquid. The expansive soil improver comprises polypropylene fibers, bagasse ash and hydrophobic magnetic ionic liquid. According to the expansive soil improvement method, expansion and shrinkage grades are divided according to the actual situation of expansive soil, and then the improvement mode is determined. The improvement method comprises the following steps: (a) spraying the expansive soil improver; (b) laying a surface improvement layer; and (c) paving a surface improvement layer and spraying an expansive soil improver in a deep layer. By adopting the method, the expansion and shrinkage of the expansive soil can be permanently and remarkably inhibited, and the shear strength is improved; and the used raw materials come from recycled materials, so that waste reutilization is realized, and the environmental pollution is small.
一种膨胀土改良剂及改良方法，所述膨胀土改良剂包括聚碳酸酯树脂基悬浮液、聚氨基甲酸酯胶粘剂和疏水性磁性离子液体。所述膨胀土改良剂包括聚丙烯纤维、甘蔗渣灰以及疏水性磁性离子液体。所述膨胀土改良方法是根据膨胀土实际情况划分胀缩等级，然后确定其改良方式。其改良方式包括(a)喷洒膨胀土改良剂；(b)铺设表面改良层；(c)铺设表面改良层联合深层喷洒膨胀土改良剂。采用本发明能够永久且显著的抑制膨胀土的胀缩性、提高抗剪强度；所用的原材料来自回收材料，实现废物再利用，对环境污染小。
