FIELD: methods or apparatus for repairing or strengthening existing bridges.
SUBSTANCE: method involves fastening the first ends of main coal-plastic plates to beam ends; stressing the main coal-plastic plates by moving the second ends thereof towards beam center; gluing the stressed coal-plastic plates to above beam; gluing additional coal-plastic plate to the beam after stress application to beam center with the use of anchoring boxwoods, which are pulled one towards another, and after glue strength development up to design strength. Additional coal-plastic plate is arranged above main ones so that additional plate covers gap between main plates and ends of above plates at beam center. After hardening of glue located under additional plate anchoring boxwoods are released and demounted.
EFFECT: increased operational reliability and improved bridge appearance.
