Problems solved by technology

The existing box girders are usually installed in sequence from the need to one direction by the bridge erecting machine, which requires the substructure of the bridge to be continuous, but the actual construction situation is complicated, and vehicles may pass under the bridge, which is not suitable for erecting the substructure of the bridge

Abstract

The invention discloses a small box girder high-low hoisting method installation construction method, and belongs to the technical field of prefabricated box girder installing.The small box girder high-low hoisting method installation construction method comprises the steps of bridge erecting machine assembling, box girder loading, transporting, box girder trial hoisting, girder feeding and hoisting. By arranging the first trigger and the second trigger, on one hand, the actual position and state of the box girder can be accurately reflected, collision between the box girder and the cover beam caused by inconformity between calculation and actual conditions is avoided, on the other hand, an engineer needs to measure the distance between the box girder and the cover beam and the inclination angle of the box girder on site, the construction efficiency is improved, and the construction cost is reduced. And meanwhile, the labor intensity of engineers is reduced, and dangers caused by measurement in the construction process are avoided.

Description

technical field [0001] The invention relates to the technical field of prefabricated box girder installation, in particular to a small box girder high-low hanging method installation and construction method. Background technique [0002] Prefabricated beams refer to beams that are prefabricated in the prefabrication field or construction site. The prefabricated beams are installed by hoisting during construction. Box beams are a type of prefabricated beams with hollow interiors. The existing box girders are usually installed in one direction through a bridge erection machine, which requires the bridge substructure to be continuous. However, the actual construction situation is complicated, and vehicles may pass under the bridge, which is not suitable for building the substructure of the bridge. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art. For this reason, the present inv...
