探地雷达在立井冷冻管道勘察中的应用

THE APPLICATION OF THE GROUND PENETRATING RADAR SURVEY TO THE DETECTION OF FROZEN PIPES

利用探地雷达技术查明立井施工过程中井壁外围制冷管道离井壁的距离,为立井顺利掘进提供可靠的数据依据,从而保证制冷管道的有效性,以防止井壁岩体脱落,积水渗漏。在数据采集的过程中,沿井壁布置测线,采用剖面法进行探测,并用环形灰度显示探测结果,使得显示结果更符合实际情况。为其他不规则施工环境成像技术提供有效参考。

Ground-penetrating radar technology was used to identify the distance of external cooling pipes from the wall in the process of shaft wall construction so as to provide reliable data basis and ensure the effectiveness of cooling pipes,thus preventing wall rock falling and water leakage.Data were collected along the wall layout line and profiling was used for detection.The detection result was shown by gray rings so that the result will be well in line with the actual situation.The results obtained by the authors provide an effective reference for other imaging technology employed in an irregular working environment.
