Abstract:In recent years, my country’s cities have developed rapidly and the construction of municipal road networks has continued to expand, resulting in more and more intersections between municipal roads and railway lines. Many roads need to be constructed across railway bridges. For roads that cross railway bridges, it is necessary to set up an effective protection system to avoid affecting the normal operation of the railway system. Railway agencies must strengthen the audit of bridge forms, spans, materials, construction, etc., to avoid affecting the safety of the railway. Operations. This article mainly elaborates on the design and construction of the protection system of cross-rail bridges on municipal roads, hoping to be helpful to relevant people.
