FIELD: construction.
SUBSTANCE: method involves drilling at least two holes in the diaphragms of adjacent superstructure beams along the entire amplified section; installation of strand bundles in holes drilled in the diaphragms; tension and fastening of strand bundles by anchoring elements on the extreme diaphragms; drilling in the upper plates at the joints of adjacent beams, in the area of voids between the diaphragms of the holes, the number of which depends on the number of voids between the diaphragms; formwork under the diaphragms of adjacent beams; filling the voids between the diaphragms with concrete through the holes in the top slabs of adjacent beams and formwork dismantle after the concrete has hardened.
EFFECT: strengthening of the bridge superstructure.
