摘要
由于沉管钢筋密集,且又要兼顾预埋件、混凝土施工等因素的影响,若采用传统开口的双肢箍难以有足够的施工空间,会影响工程质量,于是通过设计优化,引进国外摩擦焊工艺技术,在国内首次使用"J形拉钩筋"于港珠澳大桥工程中。结合港珠澳大桥工程,详细介绍了摩擦焊工艺的"J形拉钩筋"施工技术,从而拓展了设计、施工技术的发展空间。
Because of dense reinforcement of immersed tube, moreover, considering the effects of embedded parts and concrete construction and so on, open double-shaft stirrup without enough construction space effects engineering quality, J-shape hook reinforcement is used in Hong Kong-Zhuhai- Macao Bridge engineering for the first time by design optimization and introduction of friction welding technology. Based on Hong Kong-Zhuhai-Macao Bridge engineering, this paper introduces construction technology of J-shape hook reinforcement, which expands the development space of design and construction.
