METHOD OF INSTALLING FLYOVER ON SCREW PILES Russian patent published in 2018 - IPC E01D21/06 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used for the installation of inventory overpasses with supports on screw piles with combined rail and road traffic. Method for installing a flyover on screw piles, in which a mounting platform is assembled on the initial shore in close proximity to the axis of the bridge to assemble the frame-screw supports and to transfer span structures from the transport position to the working position, floodplain supports are mounted by a truck crane, span structures are installed in the axle of the bridge with a cantilever crane, water is collected by steam to install channel supports, the frame-screw supports of the channel part are assembled on the shore, delivered to the installation site by a cantilever crane and suspended on the steam for installing channel supports, the cantilever crane returns to the shore and sills the span structure, the steam for installation of channel supports leads out the frame-screw support to the place of its installation, to the edge of the bridge is supplied a car crane with universal equipment for immersion of screw piles mounted on its boom, is transferred to the working position and screws the piles of the frame-and-screw support suspended on the ferry for the installation of channel supports, a car crane with universal equipment for diving screw piles is transferred to the transport position and returns to shore, the next span structure is installed in the axle of the bridge by a cantilever crane, the frame-and-screw support is disconnected from the ferry to install channel supports.

EFFECT: reduction of labor costs, reduction of the nomenclature of technical means and an increase in the rate of erection of the overpass.
