Abstract:

Taking the continuous rigid frame construction of the main bridge of Shiqian River Bridge in Guizhou as an example, this paper introduces the concrete construction method of tensioning and grouting of vertical prestressed reinforcement for pier beam consolidation. This method introduces the concrete operation steps of tensioning and grouting in detail, which has certain reference significance for the construction of vertical prestressed steel bars.
