| 摘 要： | 城市地下管线是维持城市正常运转的大动脉，城市地下管线普查是城市规划、建设和管理的一项重要基础性工作。以某市地下管线探测工程为例，分析了现有地下管线概况，研究了地下管线探测工作流程、探测方法及相关仪器、明显管线点和隐蔽管线点定位方法和定深方法，并进行了探测结果分析。研究得出，经内业计算，各级检查明显管线点、隐蔽管线点埋深中误差均满足了相关精度要求以及各管线点重复采集检查精度均满足规程要求。研究为建立统一的地下管线信息管理系统，全面实现地下管线的信息化管理提供了技术支持。

| Abstract: | Urban underground pipeline is the main artery to maintain the normal operation of the city，and urban underground pipeline survey is an important basic work of urban planning，construction and management.Taking the underground pipeline detection project in a city as an example，the current situation of underground pipelines is analyzed，and the work flow，detection methods and related instruments of underground pipeline detection，positioning methods and depth determination methods of obvious pipeline points and concealed pipeline points are studied，and the detection results are analyzed.According to the research，the mean square error of the buried depth of obvious pipeline points and concealed pipeline points inspected at all levels meets the relevant accuracy requirements and the repeated acquisition and inspection accuracy of each pipeline point meets the requirements of the regulations.The research provides technical support for the establishment of a unified underground pipeline information management system and the full realization of underground pipeline information management. |
