Determination of the technical condition of the metal bridge with wood covering

Abstract

At present, the age of most transport facilities in the Russian Federation estimated by many decades, and most require reconstruction or repair. Consequently, there is an urgent need for periodic surveys and monitoring of the condition of such facilities. The main goal of these measures is to maintain high rates of transport infrastructure efficiency, the achievement of which is impossible without examining, analyzing and evaluating parts of the structure in the aquatic environment, and, as a result, the occurrence and development of various defects and damage. The most important conditions for ensuring uninterrupted and safe traffic on the bridges of vehicles and pedestrians are the regulatory bearing capacity of the structure and cleaning of the roadway and sidewalks. Then compliance with traffic safety requirements on decks and observing the characteristics and maintaining the function of the bridge for the period of ice drift and flooding. Timely execution of works for the care, maintenance, and repair of bridge elements. Technically stable structures and their reliability can be ensured by observing all the parameters of the structure of the road category and the requirements of regulatory documents. The paper presents the materials of the inspection of the bridge after repair — defect classification by groups and hazard classes — the results of determining the carrying capacity of the survey materials given.
