国内外排水管道状况评估系统对比分析研究

Comparative Analysis of Pipelines Condition Assessment Protocols at Home and Abroad

根据英国的《排水管道状况分类手册》(第四版,SRM-4)、美国的《管道评估与认证程序》(PACP)、加拿大的《下水道物理条件分类手册》(SPCCM)和中国的《城镇排水管道检测与评估技术规程》(CJJ 181—2012),对四国的排水管道状况评估系统的缺陷定义内容、缺陷代码编制方法和评估过程进行对比研究。结果表明,造成缺陷定义差异的主要原因有适用地区的不同、管道修复技术的差异、缺陷研究的进展及结构性和功能性缺陷的定义不同。造成评估结果差异的主要原因是缺陷分数赋予和评估参数选取的不同。

Comparative studies were conducted on four different protocols in this work,including the fourth edition of Sewer Rehabilitation Manual(SRM-4)in Britain,Pipeline Assessment and Certification Program(PACP)in America,Sewer Physical Condition Classification Manual(SPCCM)in Canada and Technical Specification for Inspection and Evaluation of Urban Sewer(CJJ 181-2012)in China,which aim to find out their differences in defects definitions,the characteristics of defect code compilation and the assessment processes.Major reasons for the different assessment results from each protocol have been revealed.The results show that the main reasons for the differences on the defect definitions are different application areas,different pipeline repair technologies,new progress in pipeline defect research and different definitions of structural defects and functional defects.The main reason for the difference of assessment results is the difference of defect scores and assessment parameters.
