摘要

随着地下管线非开挖技术的广泛应用，需要研制一种可实现管线方位精确测量的装置。本文采用将PSD（位置敏感器件，Position Sensitive Device）和其它元器件组合起来组成介入式测量装置，通过使测量装置沿管道行进，获得管道内若干个测量点的方位，进而拟合得到地下管线的方位。适用于内径为80mm至130mm、弯曲半径为50m至1000m的管线。通过非开挖公司提供的管道数据结合试验数据进行实例分析，证明该探测方法的测量相对误差满足施工要求。

Abstract

An underground pipeline detecting system is required because trenchless technology is common. In this paper

we designed a device to detect the orientation of the pipes underground which composed PSD (Position Sensitive Device) and other components by combining the data at different measuring site. Based on the analyzing result of experiment

an instance supplied by a trenchless company shows the relative error of the detecting method can meet the requirement of detecting in practical construction.
