摘　　要：在埋地管道腐蚀严重且路由无法更改的情况下,利用原管道内衬玻璃钢软管修复技术,但以往均以正压进行翻衬技术,存在软管承受压力、翻衬距离短等缺点,本文以管道内负压翻衬软管技术,对其原理及实施方式进行论述。When the buried pipeline is corroded seriously and the route cannot be changed,the original pipeline lining glass fiber reinforced plastic hose repair technology is used,but in the past,the positive pressure was used to turn the lining technology,which has disadvantages such as the pressure of the hose and the short turning distance,This article discusses its principles and implementation methods with the technology of turning over lining hoses under negative pressure in pipelines.
