Abstract

Abstract

The characteristics of the existing trenchless deep buried pipelines in Shanghai is summarized, and the detection methods of deep buried pipelines commonly used in current engineerings are comprehensively discussed. The applicability and limitations of each method in this area are analyzed in combination with the engineering geological conditions and pipeline types in Shanghai. Based on engineering practice, the pipeline instrument is used for preliminary tracking and positioning, and the gradient method is used to detect the depth accurately. The direct method is also used in this project to verify the effectiveness of the detection results, which provides a reference for the preparation of detection schemes for similar engineering.
- deep buried pipeline detection,
- magnetic gradient method,
- trenchless,
- high precision
