津石高速公路路基补强及路床施工技术探讨

Discussion on Subgrade Reinforcement and Roadbed Construction Technology of Jinshi Expressway

土质路基填筑追密补强及路床标准化、机械化施工对解决土质复杂、工期短、工后沉降不足等问题起到关键作用。在补强中采取强夯和冲击碾压等多种组合措施,充分体现措施的合理性和科学性,路床施工中区段流程合理的划分,洒布车、冷再生、推土机、刮平机、振动碾等配套机械的使用,充分体现了机械化施工的优点,提高了施工的效率,确保了施工的可控性。

The filling and strengthening of soil subgrade,standardization of roadbed,and mechanized construction play a key role in solving the problems of complex soil,short construction period,and insufficient settlement after construction.In the reinforcement,various combined measures such as dynamic compaction and impact rolling are adopted,which fully reflect the rationality and scientificity of the measures.Reasonable division of section flow during road bed construction,the use of supporting machinery such as sprinklers,cold recycling,bulldozers,scrapers,and vibratory mills fully reflect the advantages of mechanized construction,improve the efficiency of construction,and ensure controllability of construction.
