Wherein, the steel bar corrosion is caused by lower filling degree of cement-based grouting slurry in the prestressed pipeline (corrugated pipe) in the construction process.

Specifically, in the construction process of the prestressed concrete structure bridge, cement-based grouting slurry bodies are filled in prestressed pipelines (corrugated pipes) in the girder body, so that the steel stranded wires are completely wrapped by the cement-based grouting slurry bodies, the prestressed steel stranded wires can be protected, the prestressed steel stranded wires can fully play a role, and the bearing capacity and the service life of the prestressed concrete structure bridge are further improved.

Once the filling degree of the cement-based grouting slurry in the prestressed pipe (corrugated pipe) is low, part of the prestressed steel strands in the prestressed pipe are directly exposed to air after the cement-based grouting slurry is solidified. Over time, the prestressed steel strands exposed to the air gradually rust, thereby greatly reducing the overall bearing capacity and the service life of the prestressed concrete structural bridge.
