摘要
结合广东省地方标准《城镇公共排水管道检测与评估技术规程》DB44/T1025-2012的发布实施,分析了国内外排水管道检测与评估的发展历程和主要依据,介绍了规程的编制背景和主要内容。排水管道结构性缺陷分为10种,功能性缺陷分为7种;管道评估的内容分为缺陷定义(缺陷分类、缺陷特征描述、缺陷定级和缺陷打分),管段缺陷严重程度的评估、管段缺陷量的评估、管段修复指数和养护指数的计算。
Combined with the Guangdong provincial standard 《The urban public drainage pipeline detection and evaluation technology regulations》(DB44 /T1025-2012) promulgated and implemented,analyzed the domestic and foreign the development process and the main basis of the drainage pipeline detection and evaluation,introduced the procedure of establishment background and main content.The structural defects of the drainage channels are divided into 10 species,the functional defects divided into seven kinds;the pipeline assessment of content is divided into the defect definition(defect classification,defect characterization,defect classification and defect scoring)、 the assessment of the severity of the pipe segment、 pipe defect evaluation、 pipe segment repair index and curing index calculation.
