Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0040] like Figures 1 to 3 As shown, a very asymmetrical bridge IVRS intelligent vector rotation automatic control system, the extremely asymmetrical bridge includes a left bridge body built on the left bank and a right bridge body built on the right bank, the left bridge body and the right bridge body are constructed oppositely and have the same structure. The left bridge body includes the left tower bridge 1, the left main beam 2 and the left main cable 4. The left tower bridge 1 includes the lower concrete pier and the upper left steel truss 3. The left main girder 2 is horizontally fixed on the top of the concrete pier, and the left steel truss 3 is fixed to the top of the left main beam 2. The left steel truss 3 includes two, and the two left steel trusses 3 are located on both sides of the left main beam 2 respectively.

Abstract

The invention discloses an extremely asymmetric bridge IVRS intelligent vector rotation automatic control system, the extremely asymmetric bridge comprises a left bridge body and a right bridge body, and the left bridge body and the right bridge body are constructed oppositely and have the same structure; the left bridge body comprises a left tower bridge, a left main beam, a left main cable, a left main cable hinge collecting assembly, a left vector rotating support and a left laser alignment assembly. The IVRS intelligent vector rotation automatic control system further comprises a controller. The controller is in signal connection with the left vector rotation support, the right vector rotation support, the left laser alignment assembly, the right laser alignment assembly, the left main cable hinge collecting assembly and the right main cable hinge collecting assembly. The IVRS intelligent vector rotation automatic control system comprises the following working steps of (1) primary alignment of the main beam, (2) horizontal alignment of the main beam and (3) height alignment of the main beam.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, in particular to a construction control method for a swivel bridge, and more particularly to an IVRS intelligent vector rotation automatic control system for extremely asymmetric bridges. Background technique [0002] With the continuous improvement of the road network of basic traffic construction in my country, the intersection of new lines and existing traffic lines is inevitable. In order not to interrupt traffic or reduce the impact of construction on the traffic of existing traffic lines, swivel bridge technology is generally used for construction. Therefore, the newly built overpass swivel bridge plays an important role in crossing existing railways, even high-speed railway lines and expressways. There is an extreme working condition of the over-the-line swivel bridge across the existing high-speed railway line, that is, limited construction space, extremely tight construction ...
