摘要
虎门二桥大沙水道桥东塔高193.1m,拟采用一泵到顶的混凝土泵送技术,针对该超高泵送混凝土施工技术,试验人员经过查阅相关资料、优选材料、采用双掺技术优化配合比设计,在施工过程中,严格控制混凝土工作性能,保证虎门二桥东塔混凝土顺利施工完成。
The east tower of Dasha waterway of Humen Second Bridge is 193.1 m high.IT IS planned to adopt a pump-totop concrete pumping technology.FOR the super-high pumping concrete construction technology,the test personnel optimize the mix ratio by consulting relevant materials,preferred materials and adopting double-mixing technology design,in the construction process,strictly control the concrete performance,to ensure the smooth construction of the East Tower concrete of Humen Second Bridge.
