BRIDGE OVERPASS PIPE-CONCRETE STRUCTURE Russian patent published in 2019 - IPC E01D2/00 

FIELD: building of bridges.

SUBSTANCE: invention relates to construction of small and medium bridges, overpasses and can be used in structures of corresponding span structures. Bridge span-structure structure consists of upper and lower bearing parts, in which lower bearing part consists of at least one pipe-concrete longitudinal beam, and upper part of orthotropic plate with shaped cutouts in form of upper surface of beam, with possibility of tight laying of plate on beam and rigidly connected with it; it is made modular, consisting of mounting blocks with at least one beam; pipe-concrete longitudinal beams are made pre-stressed; pipe-concrete longitudinal beams are arranged with arrangement of concrete core in upper part of inner volume of pipe and rigid steel elements in lower part; pipe-concrete longitudinal beams are made with attachment to transverse ribs of orthotropic plate.

EFFECT: technical result is increased bearing capacity, durability, manufacturability, repairability.
