- 西气东输管道工程冀宁支线定向钻穿越,其补口采用辐射交联聚乙烯热收缩带,针对冬季施工气温低、补口带易出现皱褶的实际情况,根据施工经验,介绍了防止牺牲带起皱的施工控制要点。
In pipeline directional drilling crossing of Ji-Ning branch line of West to East Gas Transportation Pipeline, the radiation crosslinked polyethylene heat shrinking strips are used in the field joints. Gonstructing under low air temperature in winter, the field joints are easy to crinkle. This paper intxoduces key matters of preventing crinkles of shrinking strips on the basis of construction experience.2006,1(1): 77-78 收稿日期：2005-4-15分类号：TE973.3作者简介：高云青(1973-),男,辽宁凌源人,工程师,1996年毕业于承德石油高等专科学院,现从事管道施工技术管理工作.
