Reconstruction of the bridge using heavy lifting technique

Abstract

In work the problem of use of Heavy Lifting technology («Rise of heavy constructions») for dismantling of the flying structure of the bridge at its reconstruction is considered. The questions of development and application vertically of drawbridges are raised. Contribution of foreign designers to development of adjustable flights. Experience of modern construction of bridges, using a method, for mounting of metal constructions of bridges is considered. The importance of short-term repair and reconstruction of bridge constructions as most important components of a transport network of the country is noted. Reconstruction of the bridge through the Tobol River on federal highway R-404 in the Tyumen region is briefly considered. Works of authors, about technology of safe use of lifting frames for rise and lowering of segments of steel concrete bridges and beams for a sliding of flying buildings from previously strained concrete. Foreign and domestic experience of use of Heavy Lifting technology for mounting and dismantling of bridge constructions is considered. On the example of works on dismantling of the flying building at reconstruction of the bridge through the Yuganskaya River of a channel on km 740,863 highways R-404 Tyumen-Tobolsk-Khanty-Mansiysk are shown to feature of works on this technology, the arising problems and ways of their solution. It is noted that use of Heavy Lifting technology allows carrying out reconstruction to the shortest possible time, having saved considerable resources.
