一种用废弃电石渣改良膨胀土路基填料的方法技术

目前针对膨胀土固化剂研究尚不成熟，缺乏经济高效的专用固化剂，本发明专利技术提供一种以工业废电石渣为原料的一种用废弃电石渣改良膨胀土路基填料的方法，该方法用电石渣作为固化剂改良膨胀土路基；将电石渣掺加到膨胀土中，控制含水率为18%-20%，充分搅拌，使其均匀，电石渣的掺量为：干电石渣的质量为膨胀土干土质量的6～10%。本发明专利技术不仅可以降低固化剂成本，具有显著的固化效果，更能将工业废料电石渣变废为宝，起到综合利用和保护环境的作用。

Method for improving filler of expansion soil subgrade by using waste carbide slag

At present for the expansive soil curing agent research is not mature, the lack of efficient economic special curing agent, the invention provides a kind of industrial waste residue of calcium carbide as raw materials using carbide slag modified expansive soil subgrade filling method was abandoned, the method of using carbide slag as curing agent for the improvement of expansive soil subgrade; carbide slag added to the soil, the moisture content is 18%-20%, fully mixing control, the uniform mixing amount of carbide slag is: quality of dry carbide slag for expansive soil dry soil quality from 6 to 10%. The present invention not only can reduce the cost of curing agent, but also has obvious curing effect, can make industrial waste and carbide slag into waste, and play the role of comprehensive utilization and environmental protection.
