近年来,在城市管线敷设过程中,大量运用了非开挖施工技术。此类管线埋藏深,难以测定其准确位置,增加了后期交叉管线施工的安全风险。为了解决该类管线的定位问题,本文着重介绍了惯性陀螺仪在非开挖施工管线定位测量中的应用,并将其与导向仪进行了对比分析。通过实例,验证了惯性陀螺仪定位技术在非开挖施工管线定位测量中的可行性,并且有着其他测量技术不可比拟的优势。 In recent years, in the city pipeline laying process, extensive use of trenchless construction technology. Buried deep in such a pipeline, it is difficult to determine its exact location, increasing the safety risk of late cross-pipeline construction. In order to solve this kind of pipeline localization problem, this article emphatically introduces the application of inertial gyroscope in the trenchless construction pipeline positioning measurement, and compares it with the guide instrument. The feasibility of inertial gyroscope positioning technology in the location measurement of trenchless construction pipelines was verified through examples. And the advantages of other measurement techniques are unparalleled.
