Research on Construction Technology for the Precise Positioning of Ultra-Deep Steel Pipe Columns in Deep Foundation Pits
Based on the deep foundation pit excavation project of the Hangang Station of Wuhan Metro Line 12,this project adopts the cover and cut-top down method of deep foundation pits to construct its main structure,and studies and innovates the hanging positioning technology of ultra-deep steel pipe columns in this process.By optimizing the construction technology,and applying advanced monitoring technology and precise positioning technology,the ultra-deep steel pipe column is suspended with high precision under the cover and cut-top down construction condition of deep foundation pits by the"three elevation positioning method",so as to ensure construction quality and the project progress,and lay the foundation for future similar projects.
