摘要
以武汉地铁12号线汉钢站深基坑开挖工程为依托,采用深基坑盖挖逆作法下进行主体构造施工,并对此工序下超深钢管柱的垂吊定位技术进行研究创新.通过以优化施工工艺、应用先进监测技术以及精准定位技术,通过"三项标高定位法"在深基坑盖挖逆作施工条件下实施超深钢管柱高精度垂吊,以保证施工质量和工程进度,并为今后的类似工程打下基础.
Abstract
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.
