CONSTRUCTION SITE of reinforced concrete road bridge of continuous systems, restore high-speed way

摘要

The invention relates to the field of construction and can be used in emergency situations, in conditions of acute shortage of time for fast recovery on the old axis of concrete highway bridges a continuous system. The object of the utility model is to reduce logistics costs for the restoration of damaged concrete highway bridges a continuous system on an old axle under conditions of emergency recovery and a significant (3 ... 5 times) increase at the same rate of recovery of such bridges. Said technical problem is solved due to the fact that in the proposed design gap is covered spans average road collapsible axle (SARM) by longitudinal sliding, with the nodes bearing superstructure SARM not wound and installed near the axes of surviving reinforced concrete bridge, the conjugation carriageways SARM and concrete bridge is in the form of elevated portions of track of blocks stacked on the auxiliary support, the bases of which are fixed by means of several homonym lichenie cut in the canvas of the bridge roadway concrete. As a result of the proposed design for the recovery rate of the old concrete road bridges axis a continuous system increases 3 ... 5 times. complexity is reduced recovery of each bridge of 3 ... 4 times and 45 ... 50% reduced cost reconstruction.
