基于锤击式预成孔竖直剖面法的深埋过江管线探测技术及应用
Detection technology and application for deep-buried river-crossing pipelines based on hammer-drilled preborehole vertical profiling
摘要
Abstract
River-crossing pipelines constructed by trenchless methods are deeply buried with weak sig-nals,posing challenges for surface-water detection.In this practical research,a hammerdrilled pre-borehole approach was employed to strategically arrange detection points without compromising pipe-line structural integrity.Electromagnetic vertical profiling measurements and subsequent data fitting successfully acquired the precise spatial coordinates of target pipelines.When applied to a power pipe-line beneath the Pearl River where surface signals were undetectable,this method achieved the high-precision localization of ultradeep pipelines(>24 m burial depth).The detection principle,implemen-tation framework,and operational protocols established herein provide a reference for the detection of deep-buried river-crossing pipelines in navigable waterways.关键词
