Soil stabilizer for road surface layer and preparation method of soil stabilizer
The invention discloses a soil stabilizer for a road surface layer and a preparation method, and relates to the technical field of soil stabilizers. The cleaning agent comprises the following components in percentage by weight: 3-5% of sodium silicate, 1-2% of polyacrylamide, 0.5-1.5% of ethylene glycol, 0.5-1.0% of a silane coupling agent, 0.2-0.5% of titanium dioxide, 0.1-0.3% of nano montmorillonite, 0.01-0.1% of a defoaming agent, a proper amount of a pH regulator for maintaining the pH value to be 7-9, and the balance of water. After the liquid soil stabilizer is mixed with soil, the compressive strength of a road surface layer can be remarkably improved, the compressive strength can reach 4.6 MPa or above within 7 days, and the surface layer cracking problem is effectively reduced. The remarkably improved compressive strength is mainly benefited from the interaction between chemical components contained in the curing agent and soil particles, a more compact structure is formed, and the overall stability of the soil is enhanced. Besides, gaps among soil particles can be effectively filled by using the curing agent, and permeation and loss of water are reduced, so that the phenomena of soil expansion and shrinkage caused by water change are reduced.
本发明公开了一种用于道路面层的土壤固化剂及制作方法，涉及土壤固化剂技术领域。本发明包括以下重量百分比范围的组分：硅酸钠3‑5％，聚丙烯酰胺1‑2％，乙二醇0.5‑1.5％，硅烷偶联剂0.5‑1.0％，二氧化钛0.2‑0.5％，纳米蒙脱石0.1‑0.3％，消泡剂0.01‑0.1％，pH调节剂适量，以维持pH值在7‑9之间、余量为水。本发明的液态土壤固化剂与土壤混合后，能够显著提高道路面层的抗压强度，7天抗压强度可达4.6兆帕以上，有效减少面层开裂问题。这一显著提升的抗压强度主要得益于固化剂中所含的化学成分与土壤颗粒之间的相互作用，形成了更为紧密的结构，增强了土壤的整体稳定性。此外，固化剂的使用能够有效填充土壤颗粒之间的空隙，减少了水分的渗透和流失，从而降低了因水分变化引起的土壤膨胀和收缩现象。
