近年来,随着客运专线的不断发展,铁路桥梁的施工数量逐日增加,日渐增多的施工技术开始应用在铁路桥梁施工中,其中铁路桥梁用沉井进行承台基坑防护的施工技术就是一种得到比较广泛应用的施工技术。本文分析、总结了铁路桥梁深水基础沉井基坑防护施工的施工质量及关键技术控制,为相关工程建设提供依据。 In recent years, with the continuous development of passenger dedicated lines, the number of railway bridges has been increasing day by day. Increasingly many construction techniques are being applied to the construction of railway bridges. The construction technology for the foundation pit protection of the railway bridges with caisson is a Get more widely used construction technology. This paper analyzes and summarizes the construction quality and key technical control of the protective construction of deep-water caisson caisson in railway bridges, and provides the basis for the construction of related projects.
