地下管线普查,是指针对某一区域内的地下管线敷设现状进行全面调查。根据不同地区的要求,也包括对部分地面以上的出露管线进行调查。地下管线普查内容一般包括:已有管线资料的收集和管线现状调绘图的编制、地下管线探测、地下管线图的绘制等内容。地下管线的普查是地下管线其他工作的前提与基础。只有在对现有管线相关信息充分掌握的情况下,才能对地下管线进行有效合理的规划并建立完善的地下管线管理信息系统,从而对预防地下管线事故提供信息层面的保障。
Underground pipeline census, refers to a region of underground pipelines laying a full investigation of the status quo. According to the requirements of different regions, it also includes surveying some exposed pipelines above the ground. The contents of the underground pipeline census generally include: the collection of existing pipeline data and the preparation of the status quo of the pipeline drawing, the exploration of underground pipelines and the drawing of underground pipeline plans. The survey of underground pipelines is the premise and foundation of other work of underground pipelines. Only when the relevant information of the existing pipeline is fully mastered, can we effectively plan the underground pipeline and establish a perfect underground pipeline management information system, so as to provide informational protection for the prevention of underground pipeline accidents.
