| 摘 要： | 使用RD8000在探测球墨铸铁管线时,埋设较深的管线探测值经常超出限差,探测精度不能满足《城市地下管线探测技术规程》CJJ61-2003要求.针对此,在作业中进行了一些摸索,发现探测值在不同深度段与埋设值之间存在分段线性关系.

| Abstract: | Using RD8000 in the detection of nodular cast iron pipeline,deep pipeline detection value often exceeds the tolerance of it,and the detection accuracy can not meet the urban underground pipeline detection technical regulations(CJJ61-2003) requirements.For this,the operations carried out some exploration,which discovered the probe values section and buried relationship between different depths intervals and embedment values. |
