摘要
我国目前由于排水腐蚀、侵蚀、冲刷、沉积及地面荷载等影响,导致排水管道破损严重的问题在我国城市普遍存在。通过引进当前国外流行的CIPP紫外线光固化、局部树脂点状内衬修复技术等非开挖管道修复工艺,并从优缺点及经济指标等方面对比分析了传统开挖与非开挖修复工艺,展现了非开挖修复技术优越性和运用前景。
At present,due to the impact of drainage corrosion,erosion,scouring,sedimentation and ground loads,the problem of severe damage to drainage pipelines is widespread in cities in China. This article introduces the non-excavated pipeline repair technology such as CIPP ultraviolet light curing,local resin spot lining repair technology,etc,Comparative analysis of traditional excavation and non-excavation repair processes in terms of advantages,disadvantages and economic indicators,It fully reflects the superiority and wide application prospects of non-excavation repair technology.
