Composite materials used in the field of restoring the bearing capacity of reinforced concrete poles of power lines
Incoming article date: 28.03.2022The main objects in the field of inspection and strengthening of reinforced concrete structures are the bearing elements of buildings and structures, however, a huge number of structures subject to the destructive effects of negative factors are reinforced concrete power transmission line poles and lighting poles. Due to the large margin of safety, often their damage is not critical and repair and restoration work is not carried out until the final loss of the bearing capacity of the structures. This state of affairs is a consequence of the significant labor intensity and cost of strengthening work, especially for power transmission towers located far from cities. Modern reinforcement methods based on the use of composite materials allow solving this problem without significant labor costs. These methods do not require laborious and time-consuming costs, which will allow you to quickly respond to the devastating consequences of negative factors that destroy power transmission line supports and lighting poles. This article discusses the existing methods for strengthening reinforced concrete supports of power transmission lines, identifies their shortcomings and proposes new methods based on the use of composite materials.
