摘要
望京SOHO工程(T3标段)主塔楼地下4层,地上45层,檐高200m,结构外围钢柱34根,钢管柱内为混凝土,采用自密实混凝土顶升工艺。顶升开始前通过对顶升口、过浆孔、观察孔以及相贯斜柱节点进行深化设计,对异形管、挡板进行加工,对顶升混凝土进行严格质量要求,顶升开始后,在施工准备、润泵、坍落度、顶升施工、后期养护五方面进行过程控制,最终保证了顶升施工工艺的顺利进行,保证了工程质量。
Wangjing SOHO project(T3 tenders) Main Tower 4 basement,ground 45 floors,eaves height 200 m,the structure of the external steel columns 34,the steel columns of concrete,the use of self-compacting concrete jacking process.Before you begin jacking up through the top opening,a pulp hole,observation hole and intersecting oblique column node deepen design,shaped tube,baffle processing of concrete jacking strict quality requirements,after lifting begins carried out in the construction preparation,run pumps,slump,lifting construction,post-curing process control in five areas,and ultimately ensure the lifting of smooth construction process to ensure the quality of the project.
