Preparation method of consolidated soil and bubble consolidated soil
The invention discloses a preparation method of consolidated soil and bubble consolidated soil, which comprises the following steps of: preparing standard slurry by using residual mud, highway spoil and industrial solid wastes in a classified manner by adopting processes of impurity removal, crushing, screening, pulping and sand washing, then adding a cementing material and an additive in a certain proportion, and stirring to prepare consolidated soil slurry which is high in water-solid ratio and can be pumped. The consolidated soil slurry has the characteristics of self-compaction, no vibration, easiness in forming, easiness in construction and the like, and can be used for preparing consolidated soil with the strength of 0.5-20Mpa according to the change of the mix proportion of a cementing material. If the volume weight of the consolidated soil needs to be reduced, foam can be added into consolidated soil slurry through a foaming machine to prepare bubble consolidated soil, the volume weight range of the bubble consolidated soil can be 6-16 kN/m < 3 >, and the consolidated soil and the bubble consolidated soil can meet most of filling, backfilling or filling requirements in engineering construction. And partial application of low-grade concrete in engineering construction is replaced.
本发明公开一种固结土与气泡固结土的制备方法，利用余泥渣土、公路弃土与工业固废，分类采用去杂、破碎、筛分、制浆、洗砂工艺，制备形成标准泥浆，然后加入一定比例的胶凝材料与添加剂，经过搅拌制备出高水固比、可泵送的固结土料浆，该固结土料浆具有自密实、免振捣、易成型、易施工等特点，根据胶凝材料配合比的改变，可以配制0.5Mpa‑20Mpa强度的固结土。如果需要降低固结土的容重，可通过发泡机将泡沫加入固结土料浆制成气泡固结土，气泡固结土容重范围可在6‑16kN/m3之间，固结土与气泡固结土能够满足工程建设中绝大部分填筑、回填或充填的要求，并替代低标号混凝土在工程建设中的部分应用。
