WALL OF BERTH, SHORE PROTECTIVE AND SIMILAR HYDRAULIC STRUCTURES AND INTERLOCK MEANS FOR WALL MEMBER CONNECTION Russian patent published in 2007 - IPC E02B3/06 E02D5/08 E02D5/12 

FIELD: hydraulic building, particularly to erect berths, wharfs and retaining walls used for shore consolidation.

SUBSTANCE: wall includes wall members of groove-and-tongue type. The wall members are to be connected by means of interlock means. Each interlock means consists of male and female members made of rolled-steel channel profiles. The male and female members are provided with extensions having round cross-sections. Male member flanges face wall member carrying the male member. Female member flanges face from wall member carrying the female member. The extensions are rigidly connected to inner side surfaces of female member flanges and to outer side surfaces of male member flanges. The extensions have cross-sectional diameters equal to 0.6-0.9 of average space between female member flange surface and outer side surface of male member flange opposite thereto in plan view. Summary clear opening defined by male member and extensions formed on outer side surfaces of both flanges thereof is less than distance between inner surfaces of female member flanges in plan view and is greater than minimal distance between confronting outer surfaces of extensions formed on inner female member surfaces.

EFFECT: increased simplicity and reduced costs of wall erection, improved wall reliability due to wall member unification and due to provision of interlock means impermeability to ground.
