地下管线数据升级的理念及整体技术

Concept and Overall Technology of Data Upgrading for Underground Pipelines

基于广州市已经开展管线普查及竣工测量二十余年、已掌握管线数据4万km但未全面整理更新的现状基础上,通过试验与研究,在国内首次提出了地下管线"数据升级"理念,创新地建立了管线信息动态更新的新模式,建立了管线数据升级的技术框架体系及技术工作流程,并成功地在广州市全面实施。从而为本轮全国范围大普查所获取的数百万公里管线数据的现势性如何保进行更新提出了明确的技术路线与工作方向。

We have conducted general survey and completion acceptance survey of underground pipelinesfor more than20years in Guangzhou.We have get the pipeline data of more than40,000km in our data system in the end of2015,but the data has not been fully collated or updated.Through experiments and research,the concept of"data upgrading"for underground pipelines is put forward for the first time in China,and a new method of updating pipeline information is creatively established.Technology framework and technical workflow of“data upgrading”for underground pipelines are established,and successfully implemented in Guangzhou in2016-2017.Therefore,the direction and solution is put forward for how to update the pipeline data of millions of kilometers which has been obtained by the national wide gener al survey of underground pipelines.
