Abstract

Urban infrastructure has become more complex with the rapid development of urban transportation networks. In urban environments with limited space, construction of facilities like subways and bridges may mutually influence each other, especially when subway construction requires passing under bridges. In such cases, pile foundation replacement technology is often necessary. However, this technology is highly specialized, with a lengthy and risky construction period, and high costs. Personnel must be proficient in key technical aspects to ensure construction quality. This article discusses the technical principle, construction process, and core technology of pile foundation replacement, along with the application of this technology in subway tunnel crossing bridge projects, supported by engineering examples for reference.
地铁隧道跨线桥桩基施工技术
随着城市交通网络的快速发展,城市基础设施变得越来越复杂。在空间有限的城市环境中,地铁和桥梁等设施的建设可能会相互影响,特别是当地铁建设需要从桥下通过时。在这种情况下,往往需要采用桩基置换技术。然而,这种技术专业性强,施工周期长,风险大,成本高。施工人员必须精通关键技术环节,以确保施工质量。本文探讨了桩基置换的技术原理、施工工艺、核心技术,以及该技术在地铁隧道过桥工程中的应用,并辅以工程实例,以供参考。
