Title: Process of reconstruction of beam bridge
Inventor: VYLEGZHANIN A A

Abstract: FIELD: bridge construction and repair. SUBSTANCE: invention can find use in repair and reconstruction of steel and steel-reinforced concrete bridges with one, two or more superstructures with water flow rate less than 100 cu m/s and viaducts. Process of reconstruction of beam bridge that has at least one superstructure includes dismounting of all superstructures, replacement of one superstructure with ground-filled structure. Novelty of approach lies in that ground-filled structure is mounted on existing pile trestles of superstructure with their subsequent joining. Existing trestles are shortened in points of ground-filled structure resting on them prior to mounting. Non-engaged trestles of superstructure are shortened when there is necessity to conduct mounting or ground filling operations for rebuilding of pavement of bridge and road. In this case frame-and-arched structure is utilized as ground-filled structure. EFFECT: development of more economic process of reconstruction of beam bridge with use of existing pile-trestle base. 2 cl, 2 dwg
