Description

[0001] The invention relates to the technical field of bridge maintenance and reinforcement, and in particular to a carbon fiber cloth laying device for reinforcing the bottom of a bridge beam. Background Art

[0002] A viaduct refers to a bridge that crosses a deep ravine instead of a high embankment, as well as a bridge that crosses a road in an urban bridge. It is supported by high-supported towers or pillars. Cracks will appear in the viaduct after long-term use. In order to improve the strength of the bridge bottom, it is generally necessary to repair the damaged position of the bridge bottom surface with structural technology for reinforcement. In the prior art, it mainly uses adhesives to stick carbon fiber to the damaged position of concrete to integrate the water-mixed soil base material. It uses the good compressive strength of carbon fiber cloth to achieve the bearing capacity of structural reinforcement damaged components. In the construction process, it needs to unload the load, position and lay out the line, base layer treatment, brush primer, stick carbon fiber cloth, surface protection and other steps. Although it can meet the general use requirements, it does not have more effective and ideal construction equipment, and mainly relies on manual handling operations.
