Sea wall for protecting sea shores - has wide base concrete elements anchored in seabed with shaped top and staggered openings for water passage

摘要

The sea wall is constructed from separate concrete elements, each weighing approx. 120 tons. No reinforcement is used and the element fit together without connections to form a continuous length protecting against shore erosion. Each element has a wide base, approx. 15 metres, with feed for anchoring into the seabed. The upper portion is shaped on both sides, coming together to a single top section. On the side of the incoming sea, the slope is longer than on the shore side. Near the base are opening in both sides, staggered relative to each other to permit passage of sea water.
