Steel truss girder construction method for suspension bridge in upstream area of Sichuan River
The invention relates to the field of bridge construction, and particularly discloses a steel truss girder construction method for a suspension bridge in the upstream area of the Sichuan River, which comprises the following steps of: mounting and preparing a first cable loading crane, a second cable loading crane and a main cable sling; a pre-installation step of installing a first sliding support and a second sliding support; a side span beam section hoisting step; hoisting an M beam section; an S-beam section hoisting step; and folding the steel truss girder. According to the scheme, the temporary slings fixedly connected with the main cable sling are fixedly arranged on the two sides of the beam section M0, and the two sides of the beam section M0 can be more stable through the temporary slings; and meanwhile, the beam section M0 is mounted in the center of the main cable sling, so that the beam section S1, the beam section S2 and the beam section Sx can be conveniently and evenly mounted from the two sides of the beam section M0 in the S beam section hoisting step, the two ends of the beam section M0 are kept in a relatively stable state, and the beam section S1, the beam section S2 and the beam section Sx can be conveniently mounted.
本发明涉及桥梁施工领域，具体公开了一种川江上游地区悬索桥的钢桁梁施工方法，包括第一缆载吊机、第二缆载吊机和主缆吊索的安装准备步骤；安装第一滑移支架和第二滑移支架的预安装步骤；边跨梁段吊装步骤；M梁段吊装步骤；S梁段吊装步骤；钢桁梁合拢步骤。本方案，梁段M0的两侧上固定设置有与主缆吊索固定连接的临时吊索，临时吊索能够让梁段M0的两侧更加稳定；同时将梁段M0安装在了主缆吊索的中心处，便于在S梁段吊装步骤中从梁段M0的两侧平衡地安装梁段S1、梁段S2...梁段Sx，让梁段M0的两端处保持较为稳定的状态，便于对梁段S1、梁段S2...梁段Sx进行安装。
