- Abstract:
- The restoration project of the existing drainage network in a certain town, as one of the first key projects to be implemented in Shunde’s water environment governance, a combined process of steel lining and UV-CIPP was used to repair structural defects in the local DN1 200 sewage pipe network. The technical principles, construction process, and quality control of this combined process were introduced in detail, and the repair effect, over current capacity, quality acceptance, and engineering cost were analyzed. The results showed that the quality of the repaired pipeline network using this combined process was better, with a ratio of 119% between the repaired and pre repaired flow capacity, indicating an improvement in flow capacity. The comprehensive repair unit price after repair was 16 415 CNY/m.
