The method of reconstruction of the bridge over the water obstacle

 

The invention relates to a bridge. The method of reconstruction of a bridge over a water barrier Assembly includes new metal end-to-end spans, the dismantling of the old spans and installing in their place new superstructures using temporary piers in the target sites of the old bearing spans, thermodynamical, as well as floating bearings. What's new is that during the reconstruction of multi-span two-lane bridge with spans of more than 100 meters Assembly of new superstructures produced under each path in turn without interruption of traffic on the appropriate path of the existing bridge in its intertrack spaces. Dismantling the existing old superstructures under each path is produced during the interval of movement along this path by lifting jacks on the shore of the old superstructure on this path, install it on a safety cage, cleaning the old bearings, install the old superstructure on retractable pores, transverse relative to the longitudinal axis of the bridge perchatki old coastal superstructure installed on adjacent piers Nakatomi paths and drop. The dismantling of the old channel spans produced by Zavod is perchatki this old superstructure in place of the discarded old superstructure. Technical result provided by the invention is to improve efficiency and reduce time and labor for the reconstruction of multi-span bridges with spans of more than 100 meters due to the location of sites for new assemblies and superstructures and removal of old in the immediate vicinity of the bridge reconstruction and use of sustainable technologies for removal of old spans and installation of new. 1 C.p. f-crystals, 7 Il.
