- 摘要:
- 城镇供水、排污、燃气管道因结垢、腐蚀等问题不能满足正常运行要求,必须进行维修。非开挖内衬PE管修复技术可满足城镇埋地管道修复的要求,该技术具有不破坏硬化路面和建筑物、施工速度快、利于环保、适用范围广、经济效益好、可提高输送能力、修复后的管道使用寿命长等优点。文章介绍了内衬PE管修复技术的施工程序,强调了PE管道热熔焊接质量控制要求。
Rehabilitation technique for PE lined pipeline with out excavation can meet the needs of city and town buried pipelines rehabi litation. The technique has many advantages,such as without de-stroying hardened road pavement and buildings,fast construction speed,good environmental protection,wide application range,good economic benefit,increasing transportation capacity and long post-reparationoperation life.2005,4(4): 46-48 收稿日期:2005-5-26分类号:TU990.3作者简介:张扬(1966— ),男,陕西岐山人,高级工程师,1989年毕业于西南石油学院,现从事石油工程管理工作。
