摘要
金山区作为上海市主要工业区,区域内管线埋设错综复杂,分布着大量的非开挖管线,还敷设有连接各工业区的油气长输管线、连接工业区与机场的输油管线等。为了解决大埋深非开挖金属管线、管线三维碰撞等难题,项目实施中引入信标示踪法、陀螺仪三维精确定位技术、井中磁梯度法、管线三维碰撞分析等方法,并取得良好效果。
Several detecting technology are applied in JinShan’s underground pipeline detecting mainly beacon tracer method,Gyroscopic detecting method,Magnetic detecting method and pipelines collision analysis.According to the application of integrated methods,it’s got a positive effect.
