巢湖老城区排水管道健康状况的检测与评估

Inspection and assessment of drainage pipeline in old city zone of Chaohu

巢湖老城区地下水位高,排水管道役龄长,管材陈旧,加之缺乏日常维护,造成管道排水效能差,污水处理厂进水浓度低。为最大限度地发挥管道排水能力,延长管道使用寿命,采用管道闭路电视检测及潜望镜检测技术,选取具有代表性的管段进行有效地检测和评估,掌握了管道运行的健康状况,并针对管道病害提出建议。

Due to the high level of underground water, long service time of pipeline, pipe material aging and lack of routine care or maintenance, the drainage efficiency of the pipeline was poor and the influent concentration of wastewater treatment plant was low. For the purpose of maximizing the drainage capability of the pipeline and prolonging its service life, closed circuit television and quickview technology were used to test and assess the performance of the representative pipeline sections. Finally, the operation status of the pipeline was dear, and then, some advises for solving the existing problems of the pipeline were given.
