METHOD TO CLOSE SPAN AND LEVELLING DEVICE FOR REALISATION OF THIS METHOD Russian patent published in 2013 - IPC E01D21/00 

FIELD: construction.

SUBSTANCE: first in building slips they perform check assembly of end and closing panels, cutting of edges in end and closing panels and their mutual fitting for welding, temporary fixing elements and levelling devices are attached to cantilever and closing panels. End panels are joined to cantilevers of span stiffening girder cantilevers, their position is adjusted along line and grade, a mounting gap is created between them. The support part is wedged, and a closing panel is installed into the span, cantilever sections of the span are moved, the mutual position of joined panels is calibrated with the help of a levelling device, and they are joined temporarily. Then support parts are wedged out, and joints are arranged between end panels and the closing panel with the help of permanent connecting elements and electric welding, afterwards temporary fixing elements and the guide device are removed.
