摘要

污水管道通常在安装后很少进行维护。经过多年的使用,下水管道老化和恶化。本研究是首次尝试对曼谷都市圈污水管道状况进行检测的研究。利用装有闭路电视(CCTV)的机器人对两个沙井之间的下水管道内部进行视频和图像采集。该系统由公用事业商业联盟(UBA)公司运营。根据新西兰管道检验手册的评分分级制度,对排污管道的状况进行直观分析。从UBA收到闭路电视录像,并对每米下水道管道进行目视检查,评分和分级。研究区域包括定登区周围随机选取的22条道路。就结构状况而言,所有89根被检查的管道都存在表面损伤。在大约60%的检查下水道管道中发现了接缝缺陷和纵向裂缝。33%的被检查管道存在渗水,而研究区域的周向裂纹和裂纹倍数最小。在使用情况下,被检查的下水道管道中,临时堵塞、碎屑粉质和碎屑油腻的比例分别为15%、11%和4%。结构状况等级主要在4 - 5级之间,表明该地区大部分污水管道需要修复。服务状况的等级在优秀和良好之间。这是泰国首次开展此类项目。管道状况的信息以及检测和表征方法应作为维修计划和未来评估计划的参考。检查手册的调整或编制应与当地联系人合作进行。

Inspection and Understanding of Sewer Network Condition in Dindaeng District, Bangkok, Thailand
Sewer pipelines are usually operated with little maintenance after installation. After years in service, sewer pipes get old and deteriorated. The present research is the first study that attempts to inspect the condition of sewer pipelines in the Bangkok Metropolitan Area. A robot with Closed Circuit Television (CCTV) was used to capture video and images of the interior of the sewer pipelines between two manholes. The system was operated by Utility Business Alliance (UBA) Company. The condition of the sewer pipelines was visually analyzed in line with the scoring and grading system of New Zealand’s pipe inspection manual. CCTV footage was received from UBA, and each meter of the sewer pipelines was visually inspected, scored, and graded. The study area included 22 randomly selected roads around Dindaeng District. For the structural condition, surface damage was found in all of the 89 inspected pipes. Joint faulty and crack longitudinal were found in approximately 60% of the inspected sewer pipelines. Infiltration present was found in 33% of the inspected pipes, while crack circumferential and crack multiple were minimal in the study area. For the service condition, obstruction temporary, debris silty, and debris greasy were found in 15%, 11%, and 4% of the inspected sewer pipelines, respectively. The grades of the structural condition were mainly between 4 and 5, indicating that most of the sewer pipelines in the area would need rehabilitation programs. The grades of the service condition were between excellent and good. This is the first time that such a program has been conducted in Thailand. The information of the condition of the pipelines and the inspection and characterization methods should be used as a reference for maintenance programs and future assessment programs. The adjustment or development of the inspection manual should be done in collaboration with local contacts.
