经济发展推动了公路交通建设的发展,我国幅员辽阔,地形复杂,特大型桥梁的修建给施工带来了巨大挑战,城市交通线路汇合处各种类型的立交桥、内陆各种大江大河沿海海湾、海峡修建的大跨度桥梁等;特别是桥梁施工新工艺、新工法、信息化技术等不断的推广和应用,为工程的技术质量和工期进度都带来了效益的高效性,本文就跨黄河特大桥梁项目为例,对双壁钢围堰工艺在跨黄河特大桥梁承台施工中的应用作出详细阐述与分析,旨在交流公路桥梁项目施工经验,为大跨度桥梁施工积累经验和知识财富。
Economic development has promoted the development of road traffic construction. Due to the vast territory and complex terrain in our country, the construction of extra large bridges has brought great challenges to the construction. Various types of overpasses at the confluence points of urban traffic lines, overland coastal rivers, Strait bridges and other long-span bridges. In particular, the continuous promotion and application of bridge construction new technology, new construction methods and information technology have brought benefits and high efficiency for the project’s technical quality and schedule. In this paper, Bridge project as an example to elaborate and analyze the application of double-walled steel cofferdam technology in the construction of the bridge across the Yellow River in order to exchange experience in construction of highway bridges and build experience and wealth of knowledge for the construction of long-span bridges.
