Frozen soil foundation construction method
The invention relates to the technical field of engineering construction, in particular to a frozen soil foundation construction method. The construction method comprises the following steps that a waterproof material, a heat preservation and insulation material and a foundation are sequentially laid in a frozen soil layer from bottom to top, wherein the heat preservation and insulation material comprises the following components of, in parts by weight, 8-17 parts of SiO2 aerogel, 5-9 parts of polyphenyl particles, 2-8 parts of ordinary Portland cement, 5-10 parts of polyurethane foam, 8-15 parts of hollow glass beads, 3-5 parts of ethylene glycol, 2-4 parts of light ceramsite sand, 5-10 parts of polyethylene and 3-7 parts of basalt fibers. According to the technical scheme, good heat preservation and heat insulation performance can be provided for a frozen soil layer, the constant temperature of the frozen soil layer is maintained, the problems of frost heaving and thaw collapse caused by temperature changes to the frozen soil layer are effectively solved, and the stability of a foundation is improved.
本发明涉及工程建筑技术领域，尤其是涉及一种冻土地基施工方法，包括以下步骤：在冻土层中由下到上依次铺设防水材料、保温隔热材料和地基；其中，保温隔热材料包括以下重量份数的组分：SiO2气凝胶8～17份、聚苯颗粒5～9份、普通硅酸盐水泥2～8份、聚氨酯泡沫5～10份、空心玻璃微珠8～15份、乙二醇3～5份、轻质陶粒砂2～4份、聚乙烯5～10份、玄武岩纤维3～7份。本发明的技术方案能够为冻土层提供良好的保温隔热性能，维持冻土地层的恒温，有效缓解因温度变化对冻土层产生的冻胀、融沉问题，提高地基的稳定性。
