机械式螺旋缠绕管道非开挖带水修复技术应用案例

Trenchless Pipe Rehabilitation Using Machine Wound Spiral Lining Technology with Water Flow

机械式螺旋缠绕管道非开挖带水修复技术具有超高强度、可带水作业、进退自由等优势,是一种真正的非开挖管道修复技术。以2015年北京某DN1 000管道非开挖修复工程为例,介绍了机械式螺旋缠绕管道非开挖带水修复技术的原理、施工要点、控制要点、技术优势等。该工程实践效果好,可供其他工程参考。

The trenchless pipe rehabilitation using machine wound spiral lining technotogy is a true trenchless pipeline repair technology, which has the advantages of high-strength, construction with water flow, strong flexibility, and so on. Take a project of DN1 000 pipeline trenchless repair in Beijing in 2015 as an example, this paper introduced its principle of technology, construction points, control points, technical advantages and so on. The project had good practical effect and could be used as a ref- erence for other projects.
