谈大体积混凝土施工与养护

Extraction of mass concrete construction and maintenance

以岳垴特大桥工程为例,分析了大体积混凝土墩台的施工难点,从混凝土配合比设计、浇筑、振捣、养护等方面阐述了具体的施工方案,并提出了施工缝与预埋管孔的处理措施,确保了工程的施工质量。

Taking Yuenao extra large bridge engineering as an example,this paper analyzed the construction difficulties of mass concrete abutment,from the concrete mixture ratio design,pouring,vibrating,maintenance and other aspects elaborated the specific construction scheme,and proposed the process measures of construction joints and embedded pipe hole,ensured the engineering construction quality.
