FIELD: construction, particularly artificial structure, preferably reinforced concrete bridge, repair. ^ SUBSTANCE: repair method involves connecting lower belts of adjacent beams with metal sheets; securing the metal sheets to the beams by means of bolts; installing covering plates in spaces between adjacent beams so that the covering plates may be connected with beam walls; laying new concrete panel on the structure; providing development of new panel concrete strength; releasing metal sheets from beams by unscrewing the bolts; removing the covering plates; forming new paving; applying load equal to 0.25-0.35 of temporary load to each beam; securing metal sheets to beams to provide design load withstanding. The load is symmetric with respect to transversal plane of metal sheet symmetry. The panel is formed of fiber reinforced concrete. ^ EFFECT: increased simplicity and decreased operational costs, as well as reduced concrete panel deformation. ^ 3 cl, 5 dwg |
