At present, the damage of the prestressed concrete structure bridge has various expression forms, such as prestress loss, concrete damage and cracking, steel bar corrosion, support seat void and the like, and the damage can cause the reduction of the integral rigidity and the bearing capacity of the prestressed concrete structure bridge, and is an important reason for causing the diseases of the prestressed concrete structure bridge. The corrosion of the steel bars is caused by the fact that the filling degree of cement-based grouting material slurry in the prestressed pipeline (corrugated pipe) is low in the construction process.
Specifically, in the construction process of the prestressed concrete structure bridge, cement-based grouting slurry is filled in a prestressed pipeline (corrugated pipe) in a beam body, so that the cement-based grouting slurry completely wraps the steel strands, the prestressed steel strands can be protected, the prestressed steel strands can fully exert functions, and the bearing capacity and the service life of the prestressed concrete structure bridge are improved.
However, in the actual construction process, because the prestressed pipe (corrugated pipe) in the beam body is bent and has a long length, when the cement-based grouting material slurry is filled, whether air in the prestressed pipe is completely discharged or not, that is, whether the cement-based grouting material slurry is completely filled in the prestressed pipe or not, cannot be intuitively judged. Once the filling degree of the cement-based grouting material slurry in the prestressed pipeline (corrugated pipe) is low, after the cement-based grouting material slurry is solidified, part of prestressed steel strands in the prestressed pipeline can be directly exposed in the air. Over time, the prestressed steel strands exposed in the air can be gradually corroded, so that the integral bearing capacity and the service life of the prestressed concrete structure bridge are greatly reduced.
