Method and system for preventing and treating frost heaving of expansive soil channel through soilbag-silicon dioxide aerogel
The invention provides a method and a system for preventing and treating swelling soil channel frost heaving by geobag-silica aerogel, the method comprises the following steps: step 1, field environment investigation, investigation factors comprising construction conditions, soil body frost heaving degree and cost budget; 2, according to the feasibility of construction conditions, the frost heaving degree of the channel and cost budget, the form of nano-silica aerogel is selected; 3, determining the optimal thickness of the carpet type nano silicon dioxide aerogel or the optimal mixing amount of the powder type nano silicon dioxide aerogel by using an indoor test combined optimization algorithm; 4, determining the depth of a geotextile bag treatment layer according to the measured freezing depth, and then prefabricating a construction material according to the selected nano silicon dioxide aerogel form, the optimal thickness or the optimal mixing amount; and step 5, paving and rolling the soil bags on the surface layer of the expansive soil channel. According to the method, on the basis of the nature of soil body frost heaving, two direct factors of temperature and moisture influencing frost heaving are focused, and efficient and convenient prevention and control of the frost heaving of the channel can be achieved.
本发明提出了一种土工袋‑二氧化硅气凝胶防治膨胀土渠道冻胀方法及系统，该方法包括：步骤1、现场环境调查，调查因素包括：施工条件、土体冻胀程度以及成本预算；步骤2、根据施工条件的可行性、渠道的冻胀程度以及成本预算，选取纳米二氧化硅气凝胶的形式；步骤3、进行室内试验联合优化算法确定毡毯式纳米二氧化硅气凝胶最佳厚度或粉体式纳米二氧化硅气凝胶最佳掺量；步骤4、根据测定的冻结深度确定土工袋处理层深度，随后根据选定的纳米二氧化硅气凝胶形式、最佳厚度或最佳掺量预制施工材料；步骤5、膨胀土渠道表层土工袋铺设及碾压。本发明从土体冻胀的本质出发，聚焦温度和水分这两个影响冻胀的直接因素，可以实现渠道冻胀的高效便捷防控。
