上下重叠、大埋深地下管线探测技术及方法的应用研究

Research on the application of detection technology and method for the overlapped and deep underground pipelines

传统的管线探测仪,在管线普查工作中,对埋藏3m^4m范围内的金属管线效果明显。但是由于城市建设的深入,管线埋设越来越深,经常出现上下重叠的情况,传统的管线探测仪不具备对这类大埋深金属管线的探测性能。掌握上下重叠、大埋深地下管线探测技术及方法对城市建设中,提高管线基础数据是很有必要的。

In the general survey of pipelines,the traditional pipeline detector has obvious effect on the metal pipelines buried within 3-4m.However,due to the deepening of urban construction,the pipeline is buried deeper and deeper,and often overlapped up and down.The traditional pipeline detector does not have the detection performance for such large buried metal pipeline.It is necessary to master the detection technology and method of the up and down overlapping and deep buried underground pipelines for improving the basic data of pipelines in urban construction.
