Technical Research on the Mitigation of Safety Hazards in the Construction of Continuous Beams Using Suspension Cages for Elevated Sections of Metropolitan Railways

摘要

针对挂篮连续梁施工中结构失稳、高处坠落、物体打击等突出隐患，结合成都市域（郊）铁路S5线高架区间跨高岩山崖墓 群、柴桑河连续梁工程，开展隐患识别、技术整治与效果验证。研究提出结构稳定性提升、高空作业防护优化及智能监测 预警路径。应用后隐患发生率由12.5%降至3.2%，整体降幅达74.4%，单节段作业周期缩短约5%，成本效益比为2.33，表明 整治措施兼具安全性与经济性。

Abstract

Addressing prominent hazards such as structural instability, falls from height, and object strikes during the construction of hanging basket continuous beams, this study was conducted on the S13 line of Chengdu Metropolitan Railway’s continuous beam project spanning the Ring Expressway, encompassing hazard identification, technical mitigation measures, and effectiveness validation. The research proposed strategies to enhance structural stability, optimize high-altitude work protection, and implement intelligent monitoring and early warning systems. Following implementation, the hazard incidence rate decreased from 12.5% to 3.2%, representing an overall reduction of 74.4%; the operational cycle per section shortened by approximately 5%, and the cost- effectiveness ratio reached 2.33, demonstrating that the mitigation measures achieved both safety improvements and cost efficiency.
