WALL OF HYDRAULIC STRUCTURE Russian patent published in 2012 - IPC E02B3/00 E04B1/62 E04B1/64 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction of hydraulic structures (dams, bridge piers, pools, reservoirs, wells, etc.). A wall of a hydraulic structure comprises reinforcement, structural and protective layers of concrete, capsules with shells filled with an aqueous saturated solution, having different time resistance to decomposition. Capsules occupy 0.1-10% of the protective concrete layer volume. Shells are made from quellin and/or catgut and/or polyacrylamide. To fill the shells, a solution of Na₂SiO₃ or Na₂SiF₆ or Na₃PO₄ or NaF or Na₂C₂O₄ or NaIO₃ is used. In case of contact between a wall of a hydraulic structure with water medium, damage of capsule shells takes place at different times, and aqueous saturated solutions exit into a mass of protective and structural layers of concrete, which neutralise damaging action of free calcium hydroxide.

EFFECT: increased general resistance of hydraulic structures to exposure of water medium, their increased service life.
