摘要
城市排水管道在长期服役过程中面临突出的腐蚀和耐久性问题,尤其是对于大口径的干线排水管道,腐蚀类缺陷造成的结构安全隐患更是十分严峻。现对埋地管道结构缺陷检测技术研究、受损排水管道安全性评估研究、受损管道维护与修复技术研究等国内外关于受腐蚀大口径排水管道结构安全评估的研究进展进行了系统的分析和综述,并对典型及时新的排水管道健康状况评估与维护管理系统(含规范评分系统、高级健康诊断与决策管理系统)、影响大口径排水管道结构安全的外部环境因素等进行了分析研究,以供受腐蚀大口径排水管道结构安全评估与保护研究提供借鉴和参考。
The problems of corrosion and durability are critical for the urban drainage pipes in the long-term service. Especially for the large-diameter drainage pipelines, the potential safety dangers of structure caused by the corrosion and defect are very severe. The article systematically analyzes and summarizes the studies of the defect inspection technology of buried pipe structure, the safety assessment of damaged drainage pipe, the maintenance and repairing technology of damaged drainage pipe as well as the safety assessment of corroded large-diameter drainage pipes at home and abroad. The article analyzes and studies the health status assessment, and the maintenance management systems including the standard marking system, high-ranking health consultation and decision-making management system of the typical and latest drainage pipes, and the external environmental factors influencing the structure safety of large-diameter drainage pipe, which can be referred for the safety assessment and protection study of the corroded large-diameter drainage pipe structure.
