Preparation method of freeze-thaw cycle resistant clay-based fluid state solidified soil under negative temperature condition
The invention relates to a preparation method of freeze-thaw cycle-resistant clay-based fluid-state solidified soil under a negative temperature condition. The preparation method comprises the following steps: screening and metering a soil material after obtaining the soil material; respectively metering and preparing a curing agent, an anti-freezing agent and an additive according to the ratio; water is metered according to the proportion and heated to 15-20 DEG C; sequentially adding the anti-freezing agent and the additive into the heated water, and stirring to form slurry; putting the curing agent, the slurry and the metered soil material into stirring equipment for mixing and stirring; and the slurry is fully mixed and stirred by the stirring equipment to form the flow-state solidified soil. According to the preparation method of the anti-freezing-thaw cycle clay-based fluid-state solidified soil under the negative temperature condition, production and construction of the fluid-state solidified soil under the negative temperature severe condition in winter are achieved by adopting an optimized gelatinizing system, an anti-freezing agent and an additive and adopting a comprehensive anti-freezing technology combining self anti-freezing and auxiliary anti-freezing; and the engineering quality and strength of the flow-state solidified soil construction under the condition of circulating freezing and thawing caused by day and night temperature changes are ensured.
一种负温条件下抗冻融循环黏土基流态固化土的制备方法，包括如下步骤：获取土料后筛分、计量；根据配比分别计量并配制固化剂、防冻剂及添加剂；根据配比计量水并加热至15℃～20℃；向加热完成的水中依次添加所述防冻剂和所述添加剂，并拌合成浆液；将所述固化剂、浆液及计量好的土料投入搅拌设备中进行混合搅拌；在所述搅拌设备充分混合搅拌后形成流态固化土。本发明一种负温条件下抗冻融循环黏土基流态固化土的制备方法中，通过采用优化的胶凝体系、防冻剂及添加剂的使用，且自身防冻与辅助防冻相结合的综合防冻技术，实现了流态固化土在冬季负温恶劣条件下的生产及施工，并保证了昼夜温度变化导致循环冻融情况下流态固化土施工的工程质量和强度。
