摘要
介绍了主流的排水管道非开挖修复技术的原理、特点、适用条件和发展趋势,包括翻转原位固化、紫外光原位固化、原位热塑成型、管片内衬修复等整体修复技术,和局部树脂原位固化、不锈钢双胀环等局部修复技术。并结合实际工程案例,介绍了非开挖修复工艺在城市排水管道中的具体应用情况和实施效果,可为类似工程提供参考。
The main principle,characteristics,adaptation conditions and development tendency of the trenchless recovery technology for drainage pipes are introduced,including the integral recovery technologies of inverted in-situ curing,ultraviolet light in-situ curing,in-situ thermoplastic modeling and segment lining recovery,and the local recovery technologies of local resin in-situ curing and stainless steel double expansion ring.Combined with a practical engineering case,the detailed application conditions and implementation effects of trenches recovery technologies are introduced,which can be referred for the similar projects.
