三维惯性陀螺定位技术在非开挖地下管线高精度探测中的应用研究

Application Research of 3D Inertial Gyroscope Positioning Technology in the High-precision Detection of Underground Pipelines of Trenchless Constructions

三维惯性陀螺定位技术是近些年新兴的管线探测方法,具有探测精度高、受外界干扰小的优势,在非开挖施工的超深地下管线的高精度探测中得到了广泛应用。本文以比利时REDUCT公司生产的陀螺仪管道定位系统的应用实例为基础,阐述了三维惯性陀螺定位技术的基本原理和工作方法,并根据应用实例得出一些有意义的结论。

Three-dimensional inertial gyroscope positioning technology is a new pipeline detection method developed in recent years,which has the advantages of high accuracy and little external interference in detection.It has been widely used in the high-precise detection of ultra-deep underground pipelines of trenchless constructions.Based on the application examples of gyroscope pipeline positioning system produced by the Belgian company REDUCT,this paper expounds the basic principles and working methods of three-dimensional inertial gyroscope positioning technology,and drawed some meaningful conclusions based on the application examples.
