Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge reinforcement, in particular to a road and bridge crack reinforcement structure. Background Art

[0002] Road bridges are generally composed of several parts such as roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. Bridges refer to buildings built for roads to cross natural or artificial obstacles. They are erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. Bridges will develop cracks after long-term use, and the cracks need to be reinforced to avoid bridge breakage. Therefore, manual repair and reinforcement are required. The general road bridge crack reinforcement is to fill the gaps with cement and other fillers to repair the gaps in the bridge railings. If the cracks after repair are not reinforced, they will crack again over a long period of time.

[0003] To this end, we provide road and bridge crack reinforcement structures to solve the above problems. Utility Model Content
