惯性陀螺仪技术在非开挖超埋深地下管线探测中的优势与应用

Advantages and Application of Inertial Gyroscope Technology in Non-Excavation Ultra-Depth Underground Pipeline Detection

地下管线属于隐蔽工程,由于受环境、材质、埋深等影响,现有管线探测技术很难得到较高的测量精度。随着城市基建的开发,非开挖技术、超长、小管径、超埋深等管线越来越多,传统的物探方法如管线仪、探地雷达等对该类管线探测显得无能为力,无法得到精确的空间位置。本文针对该类管线探测现有技术难题,从惯性陀螺仪原理和技术为出发点,通过实验分析、方法测量、结果对比及工程实例验证惯性陀螺仪技术在非开挖超埋深管线的探测中具有较好的探测效果,且其探测精度高,不受外界干扰影响,该方法为城市非开挖超埋深管线探测提供一种可行有效的探测依据。

Underground pipelines are concealed projects.Due to the influence of environment,material and depth,existing pipeline detection technology is difficult to obtain high measurement accuracy.With the development of urban infrastructure,there are more and more non-excavation technologies,ultra-long,small-diameter,and ultra-buried deep pipelines.Traditional geophysical methods such as pipelines and ground penetrating radars are incapable of detecting such pipelines.Unable to get precise spatial location.In this paper,the existing technical problems of this kind of pipeline are detected.Starting from the principle and technology of inertial gyro,the experimental analysis,method measurement,result comparison and engineering examples verify that the inertial gyro technology has the detection of non-excavation and deep buried pipeline.It has better detection effect,and its detection accuracy is high,and it is not affected by external interference.This method provides a feasible and effective detection basis for urban non-excavation and deep buried pipeline detection.
