宝钢2030冷轧新增汽车板重卷机组工程为技术改造工程,该工程要建设在原有厂房内,结构基本埋深深度6.5m,由于工程紧邻原有高精度冷轧连退机组线,施工期间不能影响正常生产,因此,在施工技术方案上进行了对比、优化、创新,实施了周边围护和基坑钢板桩封闭支护施工技术。应用此项技术,不仅满足了本工程的设计要求和生产使用功能,还保证了原有高精度冷轧连退机组线连续正常生产运行,实现了“双赢”目标。
Baosteel 2030 Cold Rolling newly added automobile sheet rewinding unit project is a technical renovation project, which is to be built in the original factory building. The basic depth of the structure is 6.5m. Because the project is close to the original high-precision cold rolling continuous line unit, It can not affect the normal production. Therefore, compared and optimized and innovated in the technical scheme of construction, the construction technology of the closed support of the surrounding fences and the steel sheet piles in the foundation pit has been implemented. The application of this technology not only meets the design requirements and production and use functions of this project, but also ensures the continuous normal production and operation of the original high-precision cold-rolling continuous line unit and realizes the goal of “win-win”.
