Collapsible loess roadbed reinforcing material and preparation method thereof
The invention relates to the technical field of soil stabilization, in particular to a collapsible loess roadbed reinforcing material and a preparation method of the collapsible loess roadbed reinforcing material, and the collapsible loess roadbed reinforcing material is prepared from the following raw materials in parts by weight: 10-15 parts of sodium silicate; 3 to 5 parts of SOLIDRY; 3-5 parts of a soil immobilizing enzyme; 5-10 parts of an acrylate water-based laminating adhesive; 5-7 parts of fiber strings; and 3-5 parts of nano calcium carbonate. The structure of collapsible loess particles can be changed, original cohesion in the loess particles is recombined, irreversible cohesion is generated, and filling of internal gaps is achieved; the water absorption capacity of collapsible loess particles can be weakened, the hydrophilicity of the collapsible loess particles is reduced, a shielding effect is generated on water, and a waterproof soil layer is formed; a plurality of reinforcing grid structures which are arranged in a staggered manner can be formed in the collapsible loess roadbed; in conclusion, the purposes of resisting permeation, improving the bearing capacity, reducing deformation and stabilizing the soil body for a long time can be achieved.
本发明涉及土壤稳定技术领域，具体涉及一种湿陷性黄土路基加固材料及其制备方法，该路基加固材料由以下重量份的原料制备而成：硅酸钠10～15份；SOLIDRY3～5份；土壤固化酶3～5份；丙烯酸酯水性复膜胶5～10份；纤维串5～7份；纳米碳酸钙3～5份。本发明可以改变湿陷性黄土颗粒的结构，使土颗粒内部原始内聚力重新组合，产生不可逆转的凝聚，实现内部空隙的填充；可以削弱湿陷性黄土颗粒的吸水能力，降低其亲水性，对水产生屏蔽作用，形成防水土层；可以在湿陷性黄土路基内形成若干交错布置的加固网格结构；综上所述，本发明可以达到抗渗透、提高承载力、减少变形，达到长期稳定土体的目的。
