Abstract

The invention discloses a method for preparing solidified soil from mucky muck. The method is characterized by comprising the following steps: a, controlling and mixing the mucky muck according to the particle size of 0.075-15mm; b, solidified soil raw materials meeting the requirements for working efficiency, material taking difficulty and economical efficiency are selected; c, determining the performance difference of the selected raw materials through a test; d, performing cross comparison on the performances under different mixing ratios to determine an optimal formula; e, the compressive strength is optimized by referring to the amount of the curing agent, the soil (the water content is 20% + / -2%) and the cement; f, determining the optimal water content related to the dosage of the inorganic binder, and performing a compaction test; g, performing unconfined compressive strength and CBR value test on the prepared solidified soil; h, testing an admixture for soil solidification so as to ensure the stability of the roadbed in severe weather; i, performing construction preparation, including exploration of construction roads, obstacles, pipelines and the like; j, preparing solidified soil, selecting a road mixing method or a plant mixing method, and ensuring the uniformity of the mixture; k, the prepared solidified soil is rolled and leveled, and joints are reserved; l, measures are taken to maintain the solidified soil, for example, the solidified soil is covered with a plastic film, and the maintenance time is properly prolonged; and m, carrying out road and building earthwork backfill engineering according to related standard specifications. By adopting the method, the mucky muck can be converted into the solidified soil with high performance, the solidified soil is suitable for various civil engineering applications such as highways, bridges and building foundations, the problem of utilization of a large amount of mucky muck is solved, and high-quality building materials are provided for civil engineering.
