Freeze-thaw driving force enhanced soil fixation material and application thereof in freeze-thaw desertification control
The invention discloses a freeze-thaw driving force enhanced soil fixation material and application thereof in freeze-thaw desertification control. The freeze-thaw driving force enhanced soil fixation material comprises 8-18 parts by weight of polyvinyl alcohol and 0-4 parts by weight of auxiliary components, the soil fixation method comprises the following steps: preparing a mixture, wherein the mixture is obtained by mixing soil, water and a freeze-thaw driving force enhanced soil fixation material; and carrying out mechanical enhancement, and carrying out freeze-thaw cycle on the mixture to obtain the improved soil. The freeze-thaw driving force enhanced soil fixation material comprises the polyvinyl alcohol and the auxiliary component, under the condition of freeze-thaw cycle, network structures of the polyvinyl alcohol and the auxiliary component interpenetrate and are physically crosslinked to generate hydrogel, the improvement of soil shear strength, water holding time, impermeability and the like under the condition of freeze-thaw cycle is more facilitated after the improvement of the hydrogel, and the soil fixation material has the advantages of being simple in structure and convenient to use. The soil is effectively improved in a simple mixing mode while expensive materials are not consumed, and the ecological restoration capacity of the soil is enhanced.
本发明公开了一种冻融驱动力增强型固土材料及其在冻融荒漠化治理中的应用，其中冻融驱动力增强型固土材料包括聚乙烯醇8～18重量份和辅助组分0～4重量份；固土方法包括：准备混合料，所述混合料为土壤、水和冻融驱动力增强型固土材料混合得到；力学增强，对所述混合料进行冻融循环，得到改良后的土壤。本申请中冻融驱动力增强型固土材料中包括聚乙烯醇和辅助组分，在冻融循环的条件下，二者网络结构互穿进行物理交联后可生成水凝胶，通过水凝胶改良后更有利于冻融循环条件下的土壤抗剪强度、持水时间及防渗性等的提升，在不耗费昂贵材料的同时，利用简单拌和的形式，将土壤进行有效改良，并实现增强土壤生态修复能力。
