摘要
本文介绍了宁波市深埋非开挖管线的主要探测方法,包括PCM+探测仪法、导向仪法、惯性陀螺仪法、井中磁梯度法和工程钻探法。结合宁波市轨道交通管线详查工程,简要论述了各种探测方法在实际工程中的应用,并通过实践总结了不同方法的优缺点、探测误差和经济性。本文对深埋非开挖管线探测方法的选择和确定具有指导意义,可为软土城市的管线探测工作提供借鉴。
This paper introduces the methods of deep buried non-excavation pipeline in Ningbo city,it includes the sensor detection method,inertial gyroscope method,magnetic gradient test and engineering drilling method.Combined with pipeline detection project of Ningbo rail transit,this paper briefly discusses the application of various detection methods in practical engineering,and summarizes the advantages and disadvantages,error sources and economics of different detection methods through practice.This paper has certain guiding significance for selecting non-excavation pipeline detection methods,and providing a reference for pipeline detection work in soft soil cities.
