Construction technology for applying high liquid limit soil to roadbed filling construction
The invention discloses a construction process for applying high liquid limit soil to roadbed filling construction, which comprises the following steps of: mixing cement into the high liquid limit soil in a self-excavation section to improve and treat, and simultaneously, carrying out construction by combining two methods of reducing the virtual paving thickness and increasing the rolling times in the roadbed filling construction process; specifically, for an upper embankment and a lower embankment, the high liquid limit soil is improved by adopting a method of reducing the virtual paving thickness and increasing the rolling times; and for an upper roadbed and a lower roadbed, 3% of cement is doped into high liquid limit soil for stabilization on the basis of reducing the virtual paving thickness and increasing the rolling times. According to the method, the high-liquid-limit soil in the excavation section is reasonably utilized for filling engineering construction, reference experience can be provided for similar projects in the future through summarization of technologies and processes, and good social benefits are obtained.
本发明公开了一种高液限土应用于路基填筑施工的施工工艺，包括对自身挖方区段内的高液限土进行掺水泥改良处治，同时结合在路基填筑施工过程中减少虚铺厚度、增加碾压遍数两种方法进行施工；具体地，对于上路堤、下路堤，采用减少虚铺厚度、增加碾压遍数的方法对高液限土进行改良；对于上路床、下路床，在减少虚铺厚度、增加碾压遍数的基础上对高液限土掺加3％水泥进行稳定。本发明合理利用自身挖方区段内的高液限土进行填方工程施工，通过技术、工艺总结，可为今后类似项目提供借鉴经验，取得较好的社会效益。
