非开挖管线精细探测方法分析

地下管线精细探测为在常规地下管线探测的基础上,针对工程建设中的重点区域、重点管线、疑难管线、特殊管线采用专门的仪器和方法,通过高质量、高密度或高精度的探测,为设计、施工提供更准确更详细的地下管线现状成果。其中非开挖管线的精细探测是重中之重且一直是业内难题。文中通过应用实例,验证了里奇SR-20结合微型示踪探头以及结合惯性陀螺仪定位技术在非开挖管线精细探测中的精确性和可靠性,根据场地条件和管线深度在这两种方法中进行选择,实现对非开挖管线的精细探测。

Study on fine detection methods of non-excavation pipelines

Fine detection of underground pipelines refers to the use of special instruments and methods for key pipelines, difficult pipelines and special pipelines in key areas of engineering construction on the basis of conventional underground pipeline detection, and provides more accurate and more detailed results for design and construction through high-quality, high-density or high-precision detection. The fine detection of non-excavation pipelines is the most important one, and has always been a difficult problem in the industry, as conventional material detection equipment for such pipeline detection seems powerless. Through the application example in this essay, the accuracy and reliability of Ritchie SR-20 combined with micro tracer probe and inertial gyroscope positioning technology in the fine detection of non-excavation pipelines are verified, and the fine detection of non-excavation pipelines is able to be achieved depending on the site conditions and pipeline depths.
