Abstract:Research purposes: Based on the steel tube concrete construction of Yanyan Yellow River Bridge, the research was made on pumped lift-up steel tube concrete in order to solve the difficult problems in steel tube concrete construction.
Research methods: The research was made on symmetrical life-up steel tube concrete with the methods of structural analysis computing and structural distortion through making economic and technical analysis of the conditions of bridge site and landform.
Research conclusions: The construction practice of pumped life-up steel tube concrete for Yanyan Yellow River showed the matching ratio of steel tube concrete and model selection of device were the key points for guaranteeing continuous grouting of concrete and pumped lift-up concrete could be adopted to large span and diameter steel tube concrete arch bridge in the way of symmetry for two banks and asymmetry for upper and lower reaches.
