摘要
带压开孔是一种工艺较先进的管道开孔、管道带压抢修的施工技术。它能够解决管线不停止输送介质,不降低压力,保证管线正常运行的情况下对管道进行迁改的难题。结合徐盐铁路迁改工程中遇到的DN800钢管自来水管道迁改中的实际应用,对带压开孔进行介绍。
The hot-tapping technology is a more advanced construction technology of pipe tapping and pipe repair under pressure. It can solve the problems of pipeline relocation under the condition of the pipeline not to stop the medium conveyance, not to reduce the pressure and to guarantee the normal operation of pipeline. The article introduces the practical application of hot-tapping technology in the relocation of DN800 steel running-water pipeline in Xuzhou-Yancheng Railway Relocation Project.
