In areas with restricted longitudinal slopes, it may also lead to unfeasible construction schemes
[0007] (2) When the swivel crosses the electrified railway, because the swivel construction has a large swivel area, it has swept over the railway catenary pole. At the same time, the catenary pole is restricted by the site and regulations and cannot be moved out of the s

Example Embodiment

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] like Figure 1-Figure 7 , the embodiment of the present invention provides a bridge construction method combining swivel and height adjustment, the method includes:

[0037] Turning steps: Carry out the bridge turning operation above the design line of the bridge to be turned;

[0038] Height adjustment step: After the rotation is completed, lower the bridge beam body to the design elevation.

[0039] Understandably, after the bridge beam body is lowered to the design elevation, it will be in place as designed. ...

Abstract

The invention relates to a bridge construction method for combining turning with height regulation. The method comprises the following steps of turning and height regulation, wherein the step of turning comprises the step of carrying out a bridge turning operation above the designed line position of a bridge to be turned, and the step of height regulation comprises the step of lowering the body ofthe bridge to a designed elevation. By use of the bridge construction method provided by the invention, the bridge turning operation is firstly carried out above the designed line position of the bridge to be turned, then, the body of the turned bridge is lowered to the designed elevation so as to be convenient in fully meeting a space requirement in a bridge turning process and avoiding interference with surrounding structures or railway overhead line poles and the like which can not be relocated or modified, meanwhile, the bound limitation of the turned railway/ road can be met, the longitudinal slope of the railway/ road is effectively lowered, driving comfort is improved, and an engineering construction cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a bridge construction method combining swivel and height adjustment. Background technique [0002] An overpass bridge is defined as an overpass bridge set up by a new road or railway to cross an existing road or railway. [0003] At present, the plane swivel construction method of the conventional overpass bridge is to carry out the swivel on the design line of the new road (railway). It is a one-time swivel technology. This technology needs to set up the swivel site with the same length as the swivel structure on one or both sides of the existing road (railway), and the required construction site is relatively large. [0004] When the construction site of the overpass bridge is not restricted, the construction is simple, the force is clear, safe and reliable, and it is favored by the owner, especially when crossing the railway, because it is safe and rel...
