The short characteristic of engineering-geological and hydrological conditions of the grounds of concrete constructions is given. Factors of formation of ecological conditions in a benthonic zone of a water basin of Cheboksary hydroelectric power plant are analyzed. Dynamics of change of activity and number of microorganisms in water and bed deposits of a water basin is considered. Results of specialized shooting in dry footway about a condition of concrete of a hydroelectric power plant building of and an overflow dam in 2010-2011 are stated, the comparative estimation of microbiological activity which promotes development of the vigorous activity of biocorrosion of concrete and metals is spent. It is shown high microbes prevalence the materials applied to repair work (seals of various defects in concrete designs).
Features of engineering-geological and hydrological conditions of the basis of concrete constructions are analyzed. Factors of formation of ecological conditions in a bottom zone of a water basin of Cheboksary hydroelectric power plant are analyzed. The maintenance and change of activity and number of microorganisms in water and ground adjournment of a water basin is considered. Results of specialized shooting in dry gallery about a condition of concrete of a building of hydroelectric power plant and an spillway dike in 2010-2011 are stated, the comparative estimation of microbiological activity which promotes development of active biocorrosion of concrete and metals is spent.
