ARTIFICIAL ISLAND Russian patent published in 2006 - IPC E02B17/00 

FIELD: hydraulic building, particularly to develop shallow water areas in artificial water bodies.

SUBSTANCE: artificial island comprises earth core bounded with protective belt along earth core perimeter. The protective belt is made as polygon defined by triangular projections adjoining earth core and uniformly distributed along core perimeter. The projections are filled with sand or crushed stone or gravel and have stiffening ribs mounted on projection sides. Space defined by two triangular projections form lagoons uniformly distributed along island perimeter. Ends and sides of each triangular projection are inclined to water surface. Earth core and protective belt heights are at least 2 meters greater than maximal water level in island location area. Earth core may be round or rectangular. The earth core may include sand, crushed stone, gravel or of emersed peat bed composed of segments having, for instance, triangular shapes and retained by conical holes filled with ground forming material. Stiffening ribs of triangular projections are preferably formed of railway rails fixed with reinforced concrete crossties closely laid on projection sides.

EFFECT: increased reliability of artificial island protection against weather effects and reduced artificial island building costs due to simplified island structure and due to possibility to use in-situ materials.
