Description

Technical Field

[0001] The invention relates to the technical field of concrete crack repairing, in particular to underwater concrete crack repairing equipment and a repairing method thereof. Background Art

[0002] Concrete is widely used as a core building material in various underwater infrastructure construction projects, such as cross-sea bridges, undersea tunnels, port terminals, and water conservancy dams. Due to being in the complex underwater environment for a long time, concrete structures are prone to cracks.

[0003] Chemical substances in the underwater environment, such as chloride ions and sulfate ions in seawater, can corrode concrete. Chloride ions can destroy the passivation film of the steel bars in the concrete, causing the steel bars to rust and expand in volume, thus causing the concrete to crack. Sulfate ions react with certain components in cement to produce expansive products, which can also cause concrete cracks. According to statistics, in a seawater environment, concrete structures may develop obvious corrosion cracks after 5-10 years.

[0004] As the water depth increases, the water pressure increases linearly. For every 10-meter increase in water depth, the water pressure increases by about 0.1 MPa. The huge water pressure acting on the surface of the concrete structure may cause the microcracks inside the concrete to expand, especially in the weak parts of the structure, accelerating the formation and development of cracks. Water carries granular materials such as sand and gravel, which continuously impact the concrete surface. Long-term scouring will wear away the concrete surface, destroy its structural integrity, expose the cement stone and aggregate inside, reduce the strength of the concrete, and increase the probability of cracks. This scouring effect is more significant in areas with turbulent water such as rivers and oceans.
