FIELD: building, particularly for heat-and-power engineering, namely for performing repair-and-renewal operations of reinforced concrete structures. ^ SUBSTANCE: colonnade comprises columns with support rings and protective ferrule made of shells. Shells form telescoping collars enclosing the columns and provided with discharge plates. The shells are connected to welds. Gaps between columns and protective ferrule are filled with nonshrinking mix. Protective ferrule is provided with connection pipes located at least in one level and used for nonshrinking mix pumping. Protective ferrule also has support plates for jacks and vibratory means installation. Method of cooling tower reinforcing is also disclosed. ^ EFFECT: extended time of protection against concrete erosion, increased reliability of air-tightness and waterproofing, increased load-bearing capacity. ^ 2 cl, 2 dwg |
