FLEXIBLE PROTECTIVE CONCRETE SURFACING Russian patent published in 2009 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering construction of flexible protective coatings of underwater surfaces of pipelines passages, slopes of banks and dykes against washing out by water flows and against damaged influences of carried by water flows items. Flexible protective concrete coatings contains concrete box units, implemented in the form of double-ended heavily truncated pyramids with common big rectangular base. Concrete box units are connected to each other row by row and in rows into single linen. Into protective coating there are introduced affixed to its sides concrete box units, implemented in top part in the form of heavily truncated pyramids, and in bottom part in the form of weakly truncated pyramids with common big rectangular base. Concrete box units of both kinds are connected to each other row by row and in rows by artificial ropes, which are monolithed in concrete box units. Length and number of rows of concrete box of one or other kind depends on dimensions and homogeneity of structure of protected surface.

EFFECT: invention provides reliable protection of surface with heterogeneous structure.
