Description

Combined structure of exhaust and slurry observing mechanism for filling degree enhancing device

Technical Field

The utility model relates to the technical field of bridge construction, in particular to a combined structure of an exhaust and slurry observation mechanism for a filling degree reinforcing device.

Background

At present, the prestressed concrete structure bridge has various damage expression forms, such as prestress loss, concrete damage and cracking, steel bar corrosion, support void and the like, and the damage can lead to the reduction of the integral rigidity and bearing capacity of the prestressed concrete structure bridge, thereby being an important cause for causing the damage of the prestressed concrete structure bridge. 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.

However, in the actual construction process, since the prestressed pipe (bellows) in the girder body is bent and has a long length, it cannot be intuitively judged whether the air in the prestressed pipe is completely discharged, that is, whether the prestressed pipe is completely filled with the cement-based grouting slurry when the cement-based grouting slurry is filled. 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.

For this reason, it is necessary to develop a filling degree enhancing device to solve the above problems, but one of the important links in developing a filling degree enhancing device is how to intuitively observe the exhaust process.
