摘　　要：本文以芳村大道南快捷化改造工程东新高架桥为研究背景,以快速化、装配化、绿色施工的桥梁建设为理念,提出了一种新型的桥梁防撞护栏连接形式。本文介绍了一种预制装配式桥梁防撞栏的施工工法,采用波纹管灌注超高强度混凝土和焊接的方式来连接桥梁与防撞栏。在保证防撞栏施工质量和安全的条件下,以更加合理、快速、经济且绿色环保的方式进行防撞栏施工,得到良好的经济效益及社会效应。Take DONGXIN viaduct in fast reconstruction project located at FANGCUN Avenue south as research background, the paper proposes a new type of connection concept for bridge crash barrier, based on the concept of rapid, prefabricated and green construction. During the construction process, a construction method of prefabricated bridge crash barriers is introduced, it uses corrugated pipe to inject ultra-high-strength concrete and welding to connect the bridge with the crash barriers. Under the condition of ensuring the quality and safety of the construction of the crash barrier, the crash barrier construction is performed in a more reasonable, fast, economical and environmentally friendly manner, and it has obtained a good economic and social effects.
