Abstract

The invention belongs to the technical field of bridge engineering, and specifically relates to a track alignment control method for a multi-line cable-stayed railway bridge, comprising the following steps: A: determining the construction sequence of railway lines; B: foundation construction; C: attachment construction; C1 : Beam alignment adjustment: After step C is completed, detect the alignment of the beam, and then adjust the tension of the stay cables; D: track laying. The track alignment control method of the multi-line cable-stayed railway bridge of the present application is specifically aimed at the multi-line cable-stayed railway bridge, which is opened to traffic successively, and the railway line opened to traffic is put into use first, so that it can ensure that the railway is put into use as early as possible, and then It ensures the economy in the railway construction process, greatly reduces the impact of subsequent track-laying work on the alignment of the laid track, and then ensures that the tracks of each line have a good alignment.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a track alignment control method for a multi-line cable-stayed railway bridge. Background technique [0002] With the rapid development of economy and society and the rapid progress of science and technology, the transportation industry has also made great progress. In the entire transportation industry, railway transportation is due to its high accuracy, strong continuity, large transportation volume, and low transportation costs. And other advantages, it has become an extremely important mode of transportation. [0003] In the current field of railway design and construction technology, the application of various new equipment and new construction methods has overcome traditional construction difficulties and further improved the construction level of railway lines. In order to meet higher transportation efficiency, two On the one hand, the design idea i...
