摘要

The breakwater has a monoblock elongated structure (1) made of concrete and comprising lower compartments (8-10) and upper compartments (11-13). The compartments (8-10) are filled with a heavy granular material (23) so that the structure rests directly on a basement (2) formed by riprap, according to the weight of the material. The heavy granular material is chosen among sand, gravel, crushed stone and/or low-grade ore.
