摘要
分析了钢管柱混凝土施工的难点和特点,决定采用泵送顶升浇筑法进行混凝土施工。对高流态自密实混凝土进行了试配并通过具体实践,决定采用一次顶升施工工艺,混凝土质量满足要求。
By analyzing the characteristic of concrete construction of steel pipe column, pumping lift-up pouring method is adopted during the concrete construction. Authors also do some test for the high mobility selfcompacting concrete. Based on these test data and actual engineering practice, one lift-up construction method is adopted. The concrete quality satisfied the request.
