Method for edge covering and filling of expansive soil roadbed by using octadecylamine-phosphogypsum composite curing material
The invention provides a method for edge covering and filling of an expansive soil roadbed with an octadecylamine-ardealite composite curing material, and belongs to the field of geotechnical engineering. The method comprises the following steps: preparation of an octadecylamine-ardealite composite curing material, determination of the grade of site expansive soil, preparation of modified repair soil, and edge covering of an expansive soil roadbed. The top and the two sides of the expansive soil roadbed are subjected to edge covering through the steps, and a roadbed top edge covering layer and a roadbed side edge covering layer are formed. The roadbed expansive soil is modified through resource utilization of a large amount of solid waste ardealite, on one hand, the problems that the ardealite is low in utilization rate and large in pollution can be effectively solved, and on the other hand, the problems that an expansive soil roadbed is long in construction period, high in cost, poor in long-term stability, poor in water resistance and the like can be effectively solved.
本发明提供了一种十八胺‑磷石膏复合固化材料包边填筑膨胀土路基的方法，属于岩土工程领域。本发明方法包括以下步骤：十八胺‑磷石膏复合固化材料的制备、场地膨胀土等级的确定、改性修复土的制备、对膨胀土路基的包边。通过以上步骤对膨胀土路基的顶部和两侧进行了包边，形成了路基顶部包边层和路基侧边包边层。本发明通过对大宗固体废弃物磷石膏的资源化利用来改性路基膨胀土，一方面可以有效改善磷石膏利用率低、污染大的问题，另一方面可以有效改善膨胀土路基施工周期长、成本高、长期稳定性差、耐水性差等问题。
