低收缩混凝土大面积“跳仓法”施工技术应用研究

Research on the Application of Large-scale"Sequence Construction Method"Construction Technology for Low Shrinkage Concrete

大型公共建筑的基础面积大,厚度深,涉及大体积混凝土的施工,混凝土施工难度大,文章依托具体工程项目,阐述了项目组在基础施工中采取的技术措施,选用低收缩混凝土,采用自主研发的计算软件进行水化热计算,去除部分伸缩后浇带,优化“跳仓法”施工方案,再结合BIM技术细化跳仓工序,合理布置场布,很好地解决了大面积基础的施工难题。

The foundation area of large public buildings is large with a deep thickness,involving the construction of large-volume concrete.The construction of concrete is difficult.This article relies on specific engineering projects to elaborate on the technical measures adopted by the project team in foundation construction,using low shrinkage concrete,using self-developed calculation software for hydration heat calculation,removing some expansion and contraction post pouring strip,optimizing the construction scheme of"Sequence Construction Method"refining the sequence construction process with BIM technology,and reasonably arranging site layout,effectively solving the construction difficulties of large-area foundations.
