城市排水管道缺陷检测方法及发展现状探析

Review on Defect Detection Methods and Development Status of Urban Drainage Pipeline

城市排水管道检测对整个城市的排水效果有直接影响,为了保证城市排水管道能够实现顺利排水就需要采取科学方法来进行检测。本文以福州市连坂片区排水管网改扩建工程为背景,对城市排水管道的传统检测法和现代检测法中潜望镜、CCTV、声呐、激光和电法检测的优缺点进行对比分析,并对现代检测法中CCTV、声呐和激光检测发展与研究现状进行总结,最后对排水管网改扩建工程前期排水管道检测效果进行综合评价。

The inspection of urban drainage pipeline has directly impacted the drainage effect of the whole city,so it is necessary to adopt scientific methods to detect to ensure the smooth drainage of urban drainage pipeline.In the paper,firstly,with the reconstruction and expansion project of drainage network in Lianban District of Fuzhou,the advantages and disadvantages of traditional and modern inspection methods of urban drainage pipeline,such as periscope,CCTV,sonar,laser and electricity,are compared and analyzed.Secondly,the development and research status of CCTV,sonar and laser detection in modern detection methods of drainage pipeline are summarized.Finally,the inspection effect of the drainage pipeline in the early stage of the project is comprehensively evaluated.
