Description

Technical Field

[0001] The utility model relates to the technical field of crack reinforcement for roads and bridges, in particular to a crack reinforcement device for roads and bridges. Background Art

[0002] Roads and bridges play a vital role in modern transportation infrastructure construction. They are key hubs connecting different regions, promoting economic development, and facilitating people's travel. However, with the passage of time, the continuous increase in traffic volume, and the impact of the natural environment, various problems will inevitably arise in roads and bridges, among which cracks are one of the most common diseases. Roads and bridges are subjected to a variety of complex forces during use. The repeated rolling of vehicles brings dynamic vertical loads and horizontal friction. In particular, the passage of heavy-loaded vehicles will cause large stresses within the road surface and bridge deck structure. At the same time, temperature changes will also have a significant impact on roads and bridges. In hot summers, the road surface temperature rises, and the concrete structure will expand. In cold winters, the sudden drop in temperature may cause the concrete to shrink. This repeated thermal expansion and contraction can easily cause cracks. In addition, precipitation, groundwater, and chemical erosion will gradually weaken the structural strength of roads and bridges, accelerating the formation and development of cracks.

[0003] Failure to effectively and promptly reinforce cracks in roads and bridges will lead to a series of serious consequences. First, cracks can damage the structural integrity of roads and bridges, reducing their load-bearing capacity and impacting driving safety. Vehicles encountering cracks during driving may experience bumps, affecting driving comfort and even causing loss of control. Second, cracks provide pathways for the intrusion of moisture and harmful substances. Once moisture enters the cracks, it further erodes the steel bars in the concrete structure, causing them to rust and thus reducing the durability of the structure. Over time, cracks can continue to expand, and in severe cases, may lead to partial or complete collapse of roads and bridges, posing a significant threat to people's lives and property.

[0004] Cracks will appear on roads and bridges during long-term use. The traditional method of crack reinforcement is for workers to manually use a grinder to grind the surface of the road and bridge. After grinding, the dust generated by grinding is cleaned and then the cracks are poured with repair reinforcement fluid. The process of grinding, cleaning and pouring repair reinforcement fluid requires the cooperation of multiple people and is time-consuming and labor-intensive, which brings inconvenience to the reinforcement of road and bridge cracks, thereby increasing the time for road and bridge crack reinforcement.
