AI Technical Summary
Existing anti-corrosion methods for steel pipe pile joints suffer from high costs, unstable anti-corrosion performance, or difficulty in long-term maintenance, especially on installed offshore steel pipe piles where effective protection is difficult.
Anti-corrosion pipes are installed at the joints of steel pipe piles, and a sealed structure is formed by an outer support and a grouting layer. I-beams and concrete layers are used to cover the joints to prevent seawater corrosion. Combined with an inflatable rubber strip for sealing, a stable anti-corrosion structure is formed.
It effectively improves the corrosion resistance of steel pipe pile joints, extends their service life, reduces costs, and enhances the stability and safety of the structure.
