UNIVERSAL FLEXIBLE CONCRETE COAT Russian patent published in 2009 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: universal flexible concrete coat comprises concrete blocks arranged in the form of double-sided truncated pyramids with smaller truncated bases, which are ends of concrete blocks. Lower bases of double-sided truncated pyramids of concrete blocks are arranged as concave with radius of 200-300 mm, internal angle of pyramid face equal to 40°. Distance between neighbouring concrete blocks makes 18-25 mm. Concrete blocks are connected to each other in rowwise and in rows on other bases of pyramids.

EFFECT: increased stability of coat on pipe, wider possibility to use it as weighting agent for pipelines of any diameter of 320 mm - 1220 mm, increased coating area from these blocks with preservation of its reliable adhesion to soil and higher flexibility of concrete coating.
