Скачать или смотреть ROCK ARMOUR (RIPRAP) PROTECTION OF RETAINING WALL (REVETMENT)

Rock armour (also known as riprap) placed beside a retaining wall near a water body, like in the image, serves several key coastal and hydraulic protection functions:

Functions:

1. Erosion Protection
Absorbs and dissipates wave energy to prevent erosion of the soil behind or around the retaining wall.

2. Scour Prevention
Reduces scouring action at the toe of the retaining wall caused by water currents or wave action.

3. Wave Energy Dissipation
Breaks the force of incoming waves before they reach the wall, reducing pressure on the structure.

4. Slope Stabilization
Helps maintain the integrity of sloped embankments by preventing soil movement and sliding.

5. Durability and Longevity
Enhances the life span of the retaining wall by reducing direct contact with erosive forces.

6. Drainage Aid
Allows water to pass through voids between rocks, reducing hydrostatic pressure behind the wall.

Summary:
The rock armour acts as the first line of defense, protecting both the, retaining wall and adjacent soil or embankment from wave impact, erosion, and scour, ensuring stability and structural safety over time.
