Preparation method and application of soil-coagulated rock composite material for subgrade base
The invention provides a preparation method and application of soil coagulated rock in a subgrade base layer, and the preparation method specifically comprises the following steps: S1) forming and condensing the soil coagulated rock: weighing the soil coagulated rock and soil, mixing, and forming and condensing the soil coagulated rock and soil under the action of a cross-linking agent to form a three-dimensional net structure; s2) a chemical structure adjustment stage: diagenesis elements in the soil coagulated rocks migrate through a channel formed in the soil coagulated body and are combined with the soil in the soil coagulated body in a chemical bond manner; and S3) a lithiation stage: utilizing the physical pressure effect to enable the soil aggregate to be subjected to continuous polycondensation and mineralization until the soil aggregate is lithiated to have the engineering mechanical strength and the water resistance degree meeting the requirements, so that the soil aggregate composite material can be obtained. According to the invention, cement soil, lime soil and cement stabilized macadam are replaced by the soil coagulated rock stabilized fine-grained soil, so that the construction waste and the engineering spoil are effectively utilized, the material cost is greatly reduced, the construction period is shortened, and the spoil stacking and spoil site construction cost is effectively reduced.
本发明提供用于路基基层中的土凝岩的制备方法及其应用，所述制备方法具体为S1)土凝岩的成型凝聚：称取土凝岩与土壤后混合，于交联剂作用下，使其成型凝聚，以形成立体的网状结构；S2)化学结构调整阶段：土凝岩中的成岩元素，通过土壤凝聚体中形成的通道运移，与土壤以化学键的方式结合于所述土壤凝聚体中；S3)岩化阶段：利用物理压力作用，使得土壤凝聚体持续缩聚和矿化，直至其岩化到具备符合要求的工程力学强度和耐水性程度，即可得到土凝岩复合材料。本发明用土凝岩稳定细粒土代替水泥土、石灰土及水泥稳定碎石，达到有效利用建筑垃圾和工程弃土，将大幅降低材料成本，缩短施工周期，有效减少弃土堆存和弃土场建设成本。
