摘要
从钢管混凝土配合比设计、混凝土泵压工艺设计及质量检测等方面介绍大跨径钢管混凝土拱桥混凝土泵压技术。通过良好的材料配合比和工艺设计,保证了钢管混凝土的顺利压注,可供其他类似工程参考。
Pumping pressure technology of large-span concrete-fi lled steel tubes arch bridge is introduced on its mix design, process design and quality detection. Concrete-filled steel tubes are poured successfully through great material mixture and process design, which can provide references for similar projects.
