| Abstract: | During concrete grouting of cast-in-place side span of super-high pier,triangular steel bracket needs to be installed on pier body and balanced weight is required.Imbalanced counterweight construction technique is used for cast-in-place side span of the super-high piers of a continuous large-span steel structure bridge crossing over the Yellow River.After scheme design and analysis,the construction practice proves that this technique successfully satisfies specification requirements,saves construction cost and shortens construction period. |
