随着我国经济的快速发展,交通运输量的迅速增长,城市市政基础设施路桥工程建设规模越来越大。由于钢箱形梁制作、安装快速方便的特点,近年来钢结构桥梁工程越来越受到大家的重视,并逐步取代砼结构桥梁,引领桥梁建设新时代。在金融危机下,国家计划投入4万亿用于基础建设和拉动内需。中国的公路、铁路、城市轨道交通建设等迎来快速发展的黄金周期,我国的桥梁建设也将进入高速发展的最好时期。文章介绍了上海市浦东段市政工程钢结构桥梁的拼装、吊装、组装、焊接工程特点和难点,以及钢结构桥梁安装施工过程和施工人员如何成功的应对了钢结构方面的技术难题,同时在此过程中,创造了城市独有的高架桥钢结构组合吊装新工艺。
With the rapid economic development in our country and the rapid growth of traffic volume, the construction scale of urban municipal infrastructure road and bridge is getting larger and larger. Due to the characteristics of steel box girder fabrication and installation, the steel bridge project has drawn more and more attention in recent years, and gradually replace the bridge of concrete structure and lead the new era of bridge construction. Under the financial crisis, the state plans to spend 4 trillion yuan on infrastructure and stimulating domestic demand. China’s highways, railways and urban rail transit have ushered in a golden cycle of rapid development. China’s bridge construction will also enter the best period of rapid development. This paper introduces the features and difficulties of assembly, hoisting, assembling and welding of municipal structural steel bridges in Pudong, Shanghai, as well as the steel construction bridge construction process and construction workers how to successfully deal with the technical problems of steel structure. At the same time, In the process, the city has created a unique steel viaduct lifting technology portfolio of new technology.
