高速公路路基沉陷原因及注浆施工技术的应用

Cause of Expressway Subgrade Subsidence and Application of Grouting Construction Technology

文中以某高速公路为依托,介绍了路基沉陷原因,并提出施工工艺流程,结合试验路段质量检测,研究注浆材料水灰比和水玻璃用量。研究结果表明,制作浆液时可以适当增加水灰比,降低水玻璃用量。

Based on the expressway in a province,the reasons for subgrade subsidence are introduced,and the construction process is proposed.The water-cement ratio of grouting materials and the dosage of sodium silicate are studied in combination with the quality detection of test sections.The results show that.When making grout,the water-cement ratio can be appropriately increased to reduce the amount of waterglass.
