METHOD TO INCREASE RELIABILITY AND DURABILITY OF STEEL REINFORCED CONCRETE TURBINE WATER CONDUIT Russian patent published in 2011 - IPC E02B9/06 

FIELD: construction.

SUBSTANCE: turbine water conduit comprises an internal metal shell and an external reinforced concrete lining covered with a network of cracks of various sizes. The water conduit is located in a bottom face of a concrete dam and is rigidly fixed to the dam. The water conduit is equipped with a protective coating, which is made by application of a heat-insulating paint layer (liquid heat-insulation material) on the external surface of the reinforced concrete lining, which ensures, due to heat-insulation of reinforced concrete lining against atmospheric air, improved stressed-deformed condition of the turbine water conduit, and due to hydraulic insulation - protection of reinforced concrete lining against damaging exposure of atmospheric water. The heat-insulation paint is applied with the turbine water conduit filled with discharge water, which ensures opening of cracks on the surface of the reinforced concrete lining with its pressure.

EFFECT: high efficiency of increasing reliability of an operated steel reinforced concrete turbine water conduit.
