Conclusions 1.Embedded parts of an intake and the reinforcing bars of reinforced-concrete walls can be completely protected by cathodic polarization with the use of suspended anodes.2.With consideration of the limited length of the zone of action of cathodic protection and the need to prevent the flow of currents from one chamber to another, it is necessary to install anodes in each chamber.3.It is necessary to place anodes in the lower and upper parts of the chambers with regulation of the currents of the anodes separately, depending on the current density necessary for protection.4.With consideration of the variable flow regime and application of polarization to the binary system “steel-bars of the reinforced concrete,” it is necessary to provide automatic regulation of the regimes of the cathodic protection installation.5.The current required for protection can be assumed equal to 0.2 A/m2 for the lower part of underwater elements and 0.1 A/m2 for the upper part. In this case, it is desirable in each individual case to check this parameter preliminarily before installing protection.6.An analysis of the data shows the need for careful construction of the anodes and solution of problems about their proper location in order to avoid overpolarization of the bars of reinforced concrete when using nonautomatic electrochemical protection installations. |
