摘要
于家堡金融区起步区03-15地块工程属超高层建筑,本工程主楼竖向钢管柱采用超高层自密实混凝土顶升法进行浇筑,通过选择适宜的混凝土输送泵、混凝土拌合物的原材料、配合比、混凝土泵管的布置方式,以及采取合理的顶升构造措施及顶升浇筑工艺,确保了施工质量,保证了安全,加快了施工进度。
The project of plots 03-15 in the starting area of Yujiapu Financial high buildings. Vertical steel tube columns of the main building are poured by District consists of super- using super-high self compacting concrete lifting method. The construction quality and safety are successfully ensured and construction schedule is shortened through selection of appropriate concrete pump, raw materials of concrete mixture, mixing proportion, arrangement of concrete process.
