AI Technical Summary
Traditional revetment structures are costly and have long construction periods in areas lacking concrete and stone, making them unsuitable for island and reef areas.
The revetment structure is constructed by combining coral sand formwork cushion layer with coral sand concrete blocks. The bottom layer uses coral sand formwork cushion layer, and the surface layer uses coral sand concrete blocks, including trapezoidal block structure and regular hexagonal prism shaped concrete blocks, combined with wave-breaking walls and riprap backfill.
It reduces the amount of concrete used, thereby reducing costs, while providing high-strength slope protection, making it suitable for areas lacking concrete and aggregate.
