1, repair speed
The high-pressure water jet crushing technology uses ordinary tap water as the working medium. Since the nozzle of the high-pressure water jet crusher does not directly contact with the cement concrete pavement during operation, it will not cause mechanical friction damage, and it will not lose work due to the replacement of mechanical parts. Time, and nozzles can be multi-angle operations, greatly improving the efficiency of the work.
2, small environmental pollution
High-pressure water jet crushing pavement construction process has no dust pollution, and the noise is small. After the construction is completed, the concrete waste and waste water can be sucked away with a vacuum industrial vacuum cleaner, and the operation surface is clean and tidy, complying with the “building a resource-saving and environmental protection” advocated by China. "Friendly society" requirements.
3, the scope of precision
The nozzle diameter of the high pressure water jet crusher is small. By setting the pressure value and water volume of the ultra-high pressure water jet, the crushing range and depth can be accurately positioned, so that the incisions acting on the concrete surface are small and neat, and the crushing waste is reduced to some extent. The number of improved old pavement utilization.
4, the original structure is not damaged
The high-pressure water jet crushing the local disease area has two major characteristics: First, there is no vibration in the operation process, no cracks are caused in the surrounding concrete structure, and the risk of secondary damage is reduced; second, the density of the steel bars in the disease area is large and the gap is small. High-pressure water jets are difficult to penetrate inside the steel bar, so the steel bar does not bend or break, but also achieves the effect of rust removal. Therefore, the damage to the original structure by crushing is almost zero.
5, strong adhesion
The broken concrete interface has a hard and uneven uniform surface. The original structure has a greater contact area with the new concrete and stronger adhesion. It can directly paving new cement concrete without treatment, and it is used for highway integration construction. Provides favorable conditions.
