Research on key application points of urban open cut tunnel construction technology—taking Zhengzhou Lujing road south extension project as an example
The Zhengzhou Lujing road south extension project is a complex urban tunnel construction project,and the application of its open cut tunnel construction technology is crucial for the success of the project.The article takes the southern extension project of Lujing Road in Zhengzhou as an example to explore the key points of urban open cut tunnel construction technology.Through the application of technology in the construction of bored piles and engineering piles,rotary jet grouting piles and compaction grouting,foundation pit dewatering and drainage,foundation pit excavation,structural waterproofing and drainage construction of tunnel open cut sections,and structural construction,the complex surrounding environment and high groundwater level of the project have been successfully overcome,ensuring the smooth progress and high-quality completion of the project.
