Accurate positioning method and device for integral carrying of bridge

Abstract

The invention relates to an accurate positioning method and device for the integral carrying of a bridge. The accurate positioning method comprises the following steps: three-dimensional bridge adjusting mechanisms are arranged on a carrying device bearing the bridge; the three-dimensional bridge adjusting mechanisms and jacking oil cylinders arranged on the carrying device are used for bearing the bridge together; each three-dimensional bridge adjusting mechanism is a universal oil cylinder of which the three dimensions are adjustable. The accurate positioning method and device realize the accurate positioning and shifting of the bridge by virtue of the carrying device, can effectively perform the jacking of the bridge or effectively performs accurate positioning and adjusting to the bridge when the bridge is laid down, so that the number of power auxiliary facilities in a construction site is reduced; the construction difficulty and the construction labor intensity are reduced; the construction efficiency and the construction accuracy are improved.

Description

Technical field [0001] The invention belongs to the bridge positioning technology in the bridge integral replacement technology, and specifically relates to a precise positioning method and a positioning device for realizing the bridge integral load transportation by relying on the bridge load transportation device. Background technique [0002] Bridges are affected by multiple factors such as traffic loads and natural factors. As the operating time continues, the structure will continue to deteriorate. Therefore, bridge reconstruction or reconstruction is an important issue in the later life of the bridge. However, due to traffic and site restrictions, the traditional old bridge reconstruction method requires the original bridge to be demolished and rebuilt in situ. Temporary restrictions or cut-off measures are often taken during construction, which not only takes a long time, but also has a great impact on society and traffic. Moreover, due to the restriction of construction o...

Problems solved by technology

[0003] In the prior art, after the piggyback equipment used for the overall demolition and construction of the bridge is transported to the construction site, whether it is the overall lowering of the old bridge or the overall jacking of the new bridge, it also requires a series of auxiliary mechanisms to complete the entire bridge. Accurate displacement and positioning can meet the position requirements for loading and unloading. For bridge girders with a weight of hundreds of tons, the construction of positioning and displacement is more difficult and the construction time is longer
