跨汉宜高铁特大桥混凝土连续箱梁顶推施工工艺分析

Analysis of Construction Technology of Concrete Continuous Box Girder Construction in Extra-high Railway Bridge

随着我国经济的快速发展,基础建设的进程不断加快,交通设施的建设得到了越来越广泛的关注,而桥梁施工作为道路建设中一个最重要的环节,如何在跨越公路、铁路等障碍时高起点,高标准,高质量,高效率地施工显得尤为重要。通过跨汉宜高铁特大桥的顶推段具体施工,对桥梁施工中连续梁顶推施工工艺进行阐述,探讨其工艺流程,对类似的桥梁顶推段施工作业有较高的参考价值。

With the rapid development of Chinese economy, the process of infrastructure construction is accelerating and the construction of traffic facilities has been paid more and more attention. Bridge construction is one of the most important links in road construction. Obstacles high starting point, high standards, high quality, high efficiency construction is particularly important.This paper expatiates on the construction technology of continuous beam in the construction of the bridge by means of the construction of the pusher section of the high-span railway bridge, and discusses its technological process, which has a high reference value for the similar construction work of the bridge.
