摘要
全面掌握新建小区排水管网的健康状况是城市雨污分流改造的重要内容之一,可为城市规划、建设、后续管养维护以及制定管网养护和修复计划提供依据。本文从实际生产应用的角度出发,针对传统的新建小区排水管网验收时存在“通球试验”局限性大、排水管段隐蔽点多等问题,提出了基于管道机器人(CCTV)检测技术进行排水管网验收的方法,并得出了可行的排水管道数据采集和验收方案。以济南市部分新建小区为研究对象,从雨污分流、市政接驳、管道结构性状况、管道功能性状况和检修井及雨水口这五个方面进行检测,总结分析了雨污混接风险点、管道缺陷影响因素等,证明了利用CCTV检测技术进行排水管网验收的可行性和有效性,同时为其他城市排水管网验收提供参考。
A comprehensive grasp of the health status of the drainage pipe network of the newly built residential area is one of the important contents of urban stormwater diversion transformation,which can provide a basis for urban planning,construction,follow-up custody and maintenance,and the formulation of pipe network maintenance and repair plans.From the perspective of actual production and application,this paper proposed a method for drainage pipe network acceptance based on CCTV detection technology,aiming at the problems of"through-ball test"and many hidden points in drainage pipe section in traditional new residential drainage pipe network acceptance,and obtained a feasible drainage pipeline data collection and acceptance scheme.Taking some newly built residential areas in Jinan as the research object,the five aspects of rainwater sewage diversion,municipal connection,pipeline structural condition,pipeline functional condition and manhole and rainwater outlet were tested,and the risk points of rainwater mixed connection and the influencing factors of pipeline defects were summarized and analyzed,which proved the feasibility and effectiveness of using CCTV detection technology for drainage pipe network acceptance,and provided reference for the acceptance of drainage pipe network in other cities.
