01 Operation Principle
- • Reduce the impact on the structure by changing the wave energy direction 180° and colliding it with the next wave.
- • Absorbs wave energy from the inside to reduce the amount of overtopping
- • Direct wall blocks erode the sand or gravel underneath, but returning-waves blocks are deposited or retained to prevent erosion and collapse.
- • Because the top is flat, it can be easily used and has hydrophilicity
- • · It has more of an overtopping reduction effect than T.T.P., so it is installed lower for a coastal landscape view
02 Improvement of Efficiency
- • In a hydraulic model test, about 10 times more effective in overtopping reduction than a T.T.P. inclined system
- • Excellent impact reduction and anti-scouring effect compared to straight walls
Overtopping reduction
Scour and erosion prevention
03 Structural Stability
- • Unlike the existing method of lifting through adhesive force, a winding method is used
- • Use of wire ropes without ends
Unit block numerical analysis
04 Economics
- • Installing T.T.P. is not economical because the quantity is large
- • Convergence with the column binding method can reduce construction costs by more than 20% while securing structural stability.
Secures economic feasibility by reducing quantity and area
Implementation of economical returning-waves block revetment
05 Scenery
- • T.T.P.s piled up like mountains all over the country are harming water-friendly spaces.
- • Natural coasts are reborn as hydrophilic coasts.
- • • Able to create eco-friendly coasts with safe and convenient access.
Improvement of the coastal environment
Water-friendly space secured
Forms a beautiful coast
06 Eco-Friendly
- • No way to clean up when marine waste enters the T.T.P installation area
- • Returning-waves block does not accumulate waste
- • Prevents odor and spoilage of marine waste
Easy to clean marine waste
Artificial reef function
Establishment of eco-friendly tourism infrastructure
