Title of the articleImproving the drainage system from the bridge deck of road bridges
Abstract.Formulation of the problem. The vast majority of road bridges in the Russian Federation were built quite a long time ago, when society did not yet pay much attention to environmental issues, as a result of which, on existing bridge structures, the sewage disposal system from the bridge deck is represented only by longitudinal and transverse slopes, and on those bridges where there are drainage pipes, the spillway is carried out under the superstructure without preliminary cleaning. The purpose of the study is to analyze foreign and domestic experience in improving drainage systems from the bridge deck of road bridges. The study is also aimed at identification of the most acceptable ways to solve the problem of obsolete drainage systems on bridge structures, namely, to identify treatment facilities capable of accumulating and draining water entering the carriageway of bridge structures. The study considers an example of improving an outdated drainage system from the bridge deck of a road bridge across the Bira River, in order to meet modern environmental requirements. Conclusions. The significance of the obtained results for the construction industry and the current environmental situation lies in the possibility of reducing the negative impact of the transport and road complex on the environment, which is one of the priority areas for the modernization and development of the road network of the Russian Federation. Results. The main results of the study: foreign and domestic experience in solving the issue of rational drainage of surface runoff entering the bridge deck of road bridge structures is considered, using the example of a bridge across the Bira River, solutions are proposed for the rapid drainage of water from the bridge deck, allowing them to accumulate and drain. Based on this example, a hydraulic calculation and a wastewater calculation were made
