摘　　要：埋地管道铺建时预留的分支管道接口不合适,需要在管道带压正常运行的状态下进行开孔施工。介绍了埋地燃气管道带压开孔技术的专用设备组成、操作方法、步骤和技术要点。实践证明:这项带压开孔技术的应用会更加广泛。It discussed that branch pipeline interfaces of the initial pipeline buried are inevitably inappropriate. The pressure piping must be carried on in an underline normal operation condition. Also introduced here are buried pressure gas pipeline opening technology and special equipment for composition, methods of operation, steps and the main technical points. Practice has proved that the application of the opening under pressure technology will be even more extensive.
