摘要
在道路工程过程中常常会遇到软土路基,如若不对软土路基处理则可能会导致面层出现不均匀沉降现象。使用水泥搅拌桩施工技术对软土路基进行加固,将水泥搅拌桩深入至软土层,形成进行沉降过渡段,可有效降低路基施工后的沉降量,从而避免桥头跳车现象出现。文章结合中国交建马来西亚东海岸铁路项目工程对水泥搅拌桩施工技术进行分析,并对施工检测技术展开研究。
Soft soil subgrade is often encountered in the process of road engineering.If the soft soil subgrade is not treated,uneven settlement of the surface layer may occur.Use the cement mixing pile construction technology to strengthen the soft soil subgrade,and penetrate the cement mixing pile into the soft soil layer to form a settlement transition section,which can effectively reduce the settlement after the subgrade construction,so as to avoid bumping at the bridgehead.In this paper,the construction technology of cement mixing pile is studied and analyzed in combination with the East Coast Railway Project of CCCC Malaysia,and the construction detection technology is studied.
