FIELD: construction.
SUBSTANCE: invention relates to hydraulic engineering construction of sand beaches by inwash of sea and river coasts by breakers. Device includes rows of earth-retaining elements made of material with specific weight equal to or larger than volume weight of water and arranged on retaining cables with anchors. Separate earth-retaining element is arranged in the form of trihedral prism, cross section of which represents an isosceles triangle with blunt angle at the top. Prism is oriented and fixed on rope so that one of two faces equal in area is support, and the second one is thrust one, providing for generation of lifting force. Friction anchors are used, being made of spherical segments.
EFFECT: invention makes it possible to improve reliability of device operation.
