Method for edge covering and filling of expansive soil roadbed with ardealite composite curing material
The invention relates to a method for edge covering and filling of an expansive soil roadbed with a phosphogypsum composite curing material, and belongs to the field of geotechnical engineering. The method mainly comprises the following steps: preparation of a phosphogypsum composite curing material, preparation of site expanded dry soil, preparation of modified repair soil, and edge covering of an expanded 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 1 and a roadbed side edge covering layer 2 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 water resistance and the like can be effectively solved.
本发明涉及一种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。本发明主要包括以下步骤：磷石膏复合固化材料的制备、场地膨胀干土的制作、改性修复土的制作、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，并形成了路基顶部包边层1和路基侧边包边层2。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、耐水性差等问题。
