地下管线普查项目中管线仪探测方法的研究

地下管线探测仪能在不破坏地面覆土的情况下,快速准确地探测出地下自来水管道、金属管道、电缆等的位置、走向、埋深等信息,是地下管线普查的必备仪器之一。本文以延安市城市地下管线普查项目为例,采用AP-1和RD8000两种主流的管线探测仪对不同管线探测的最佳信号施加方式、最佳频率、最小收发距、最佳收发距等技术指标进行试验研究,确定测区内不同管线、不同材质的探测方法,为地下管线普查项目中管线探测仪的使用提供借鉴和经验。

Research on Detection Method of Pipeline Instrument in Underground Pipeline Survey Project

The underground pipeline detector can quickly and accurately detect the location,direction and buried depth of underground water pipes,metal pipes and cables without damaging the ground covering.It is one of the necessary instruments for the survey of underground pipelines.Based on Yan'an urban underground pipeline census project as an example,the AP-1 and RD8000 two mainstream line detectors the best signal applied to different pipeline detection method,optimal frequency,minimal transceiver,best to send and receive from the experimental research on the technical indexes such as,determine the different pipeline measurement and detection methods,different material pipeline detector used for underground pipeline census project to provide reference and experience.
