摘要
不停输带压开孔是城市燃气管网维修和改造的关键技术,具有经济高效和安全环保等优势.在不停输带压开孔施工中,常使用双面U型卡勾来勾住并取出管道料块,但实际操作中存在U型卡勾断裂和铁屑残留等现象,研究后提出了两项设备改进措施:增加U型卡勾的数量和增设压力感应装置.同时预测了不停输带压开孔技术的自动化、智能化等发展方向.这些改进和发展趋势有望提升不停输带压开孔作业的安全性、效率和可靠性,以满足未来城市管线施工的需求.
Abstract
Hot-tapping for non-stop gas transporting pipelines is a key technology for the maintenance and renovation of urban gas pipeline networks,which has advantages such as economic efficiency,safety and environmental protection.In hot-tapping construction for non-stop gas transporting pipelines,double-sided U-shaped hooks are often used to hook and remove pipeline blocks.However,in actual operation,there are phenomena such as U-shaped hook breakage and residual iron filings.Two equipment improvement measures are proposed through research:increasing the number of U-shaped hooks and adding pressure sensing devices.At the same time,the development direction of hot-tapping technology for non-stop gas transporting pipelines,such as automation and intelligence,is predicted.These improvements and development trends are expected to enhance the safety,efficiency,and reliability of hot-tapping operations for non-stop gas transporting pipelines,in order to meet the needs of future urban pipeline construction.
