Construction technology of deck crane for hoisting entire segment of composite girder of cable-stayed bridge based on eccentric load lateral movement

Abstract

The present invention discloses a construction process of a bridge crane crane crane crane cranium with a partially shifted beam of the stacked beams, including the following steps: the tower area has assembled the beam bridge deck as the assembly platform, and through the starting upThe promotion equipment is assembled in turn, the front, the legs, the longitudinal beams, the beams, and the cars; the section beams, section beams, and second cable cable brackets are assembled to be assembled on the bridge placenta.Section beams; fix the section beams and the beams of the beams; transport the section beams to the entire section of the bridge deck through the beams;At the center of the beams of the beam beams; the entire section bridge crane drives the vertical movement of the section beam to the rotation station;After the whole section of the bridge cranes, the whole section of the bridge is positive; until the work is completed.The present invention ensures the safety and quality of construction, which can improve the efficiency of construction and reduce construction costs.

Description

technical field [0001] The invention relates to a construction technology of a bridge deck crane, more specifically a construction technology of a bridge deck crane for hoisting the entire segment of a composite girder of a cable-stayed bridge based on eccentric load lateral movement. Background technique [0002] The traditional cable-stayed bridge composite girder installation process is as follows: [0003] 1. The full-slewing bridge deck crane is suitable for the installation process of composite beam steel beam parts. The installation steps are as follows: [0004] Step 1: Transport the steel girder components to the working area of ​​the main tower hoisting station; [0005] Step 2 Use the lifting station to lift the components to the bridge deck beam transportation equipment, and transfer them to the operating range of the slewing crane; [0006] Step 3 Use the slewing crane to install the main girder, cross girder and small longitudinal girder on the side of the co...
