结合准朔铁路黄河特大桥钢管拱顶升钢纤维混凝土施工,以整体论思想为设计理念,通过大量试验,归纳总结出用于泵送顶升工艺施工的混杂钢纤维混凝土配合比设计方法,所设计出的混凝土具有大流动性且保持时间长、延后初凝并早强、可补偿收缩等性能,解决了大跨度钢管拱桥混凝土泵送顶升工艺施工难题。 Combining with the construction of steel tube dome steel fiber reinforced concrete of Zhushiu railway Huanghe super-large bridge, taking the idea of ​​holistic theory as design concept, through a large number of experiments, the hybrid steel fiber concrete mix design method for pump jacking construction is summarized. The designed concrete has the characteristics of large fluidity, long holding time, early delaying and early delaying, compensating for the shrinkage and other properties, and solving the construction difficult problem of the concrete pumping lifting process of the long-span steel pipe arch bridge.
