摘　　要：过河管的缺陷情况对污水收集系统的健康程度评估至关重要。以南京市某污水收集系统排水管网清疏、检测、排查、设计、施工一体化项目为例,分析过河管的各种检测方法,明确项目中过河管检测的技术路线,针对各种检测方法列举典型案例,并对系统收集范围内58条过河管进行结构性缺陷评估。结果表明,电法测漏和水下机器人检测技术能够在管道满水条件下对管道缺陷进行有效检测;过河管存在结构性缺陷问题的比例远大于普通管道;塑料管存在结构性缺陷问题比例远大于其他管材。The defect of river crossing pipes is crucial to the health assessment of sewage collection system.Taking the integrated project of drainage pipe network dredging,inspection,design and construction of a sewage collection system in Nanjing as an example,various detection methods of river crossing pipes are analyzed,the technical route is clarified,typical detection methods cases are listed,and the structural defects of 58 river crossing pipes within the scope of the system are evaluated.The results show that leak detection by electric method and underwater robot detection technology can effectively detect pipeline defects under the condition of full water.The proportion of structural defects in river crossing pipes is far greater than that of ordinary pipelines and the proportion of structural defects in plastic pipes is far greater than other pipes.
