Research on the Application of New Technologies in Underground Pipeline Detection

摘要:

随着城市建设日新月异，被誉为城市生命线的市政地下管网越来越受到人们重视，新方法的使用、新设备的投入，不断促进城市地下管线探测技术进步。通过将带信号源的传感器（探棒）置入目标管线，结合地面导向仪接收与分析信号，实现了管线的精准定位与埋深测量。对比分析了导向仪定位技术与常规管线探测技术的优缺点，提出了适用于非金属管道的高效探测方案，并引用实际工程案例验证了该方法的高精度与可靠性。结果表明导向定位技术有效弥补了传统方法在非金属管道探测中的不足，具有广阔的推广应用前景。

Abstract:

With the rapid development of urban construction, the municipal underground pipeline network, known as the lifeline of the city, has received increasing attention. Therefore, the use of new methods and the investment in new equipment have become a vital force in urban underground pipeline detection. By placing sensors (probes) with signal sources into the target pipeline and combining with ground-based guidance instruments to receive and analyze signals, precise positioning and burial depth measurement of pipelines are achieved. This paper compares and analyzes the advantages and disadvantages of guidance instrument positioning technology and conventional pipeline detection technology, proposes an efficient detection scheme suitable for non-metallic pipelines, and verifies the high precision and reliability of this method through practical engineering cases. The results show that guidance instrument positioning technology effectively compensates for the shortcomings of traditional methods in non-metallic pipeline detection and has broad prospects for promotion and application.
