绿色环保背景下跨高速及国省道桥梁的施工探讨

Discussion on the Construction of Bridges Across High-speed National and Provincial Roads under the Background of Green Environmental Protection

文章结合当今交通基础设施建设的现状,阐述了跨高速公路和跨国省道桥梁建设的重要性,介绍了钢结构桥梁的特点、挂篮施工技术的发展过程和操作期间关系到人身安全的注意事项,针对目前应用最为广泛的菱形桁架式挂篮技术,突出了其相比于其他类型挂篮施工技术的优势。并且,考虑到桥梁的施工可能会造成大气环境污染、水污染、光污染和噪声污染等不利影响,为积极响应国家对可持续发展的倡导,基于绿色施工原则探讨绿色施工技术,提出了绿色环保背景下跨高速公路和跨国省道桥梁的施工改善措施。

Combining with the current situation of transportation infrastructure construction,the article expounds the importance of bridge construction across expressways and transnational provincial roads,and introduces the characteristics of steel structure bridges,the development process of hanging basket construction technology and the issues related to personal safety during operation. For the diamond-shaped truss hanging basket technology,which is currently the most widely used,its advantages compared with other types of hanging basket construction technologies are highlighted. In addition,considering that the construction of bridges may cause adverse effects such as air pollution,water pollution,light pollution and noise pollution,in order to actively respond to the country’s advocacy for sustainable development,based on the principle of green construction,green construction technology is discussed. Construction improvement measures for bridges across expressways and transnational provincial roads in the context of environmental protection are proposed.
