Case Study: DN800 Sewer Rehabilitation in Suqian, China | UV CIPP Technology
In Suqian City, Jiangsu Province, we executed a high-efficiency trenchless sewer rehabilitation project on a critical DN800 underground pipeline. Using advanced UV CIPP (Cured-in-Place Pipe) technology, our team restored a 30-meter section of aging infrastructure that had reached a critical state of deterioration.
The Challenge: Severe Pipeline Corrosion and Root Intrusion
The 20-year-old concrete sewer pipe faced several structural threats that required immediate intervention:
Structural Decay: Significant thinning of the host pipe walls due to two decades of use
Root Intrusion: Aggressive root growth had caused extensive cracking and blockages
Environmental Risk: The deterioration posed a high risk of soil contamination and potential pipe collapse in a busy urban area
The Solution: Rapid UV CIPP Trenchless Repair
To minimize urban disruption and avoid the high costs of traditional excavation, we utilized the Daoyunai UV CIPP system. This trenchless method allows for "pipe-within-a-pipe" restoration without digging up the street.
Key Project Metrics
Pipe Diameter: DN800
Repair Length: 30 Meters
Total Project Time: Approximately 5 hours
Technology: UV-light curing with high-strength liners
Why Daoyunai UV CIPP Materials?
The project's success relied on the superior performance of Daoyunai liners and curing equipment:
High-Strength Liners: Engineered for maximum structural integrity and long-term corrosion resistance
Operational Speed: The liner's flexibility allows for fast pull-in, while the UV curing process is significantly faster than traditional thermal curing
Versatile Curing Equipment: Our proprietary UV system supports both Mercury and LED lamp options, offering the adaptability to cure various liner types currently available on the global market
By choosing UV CIPP, the city of Suqian avoided weeks of road closures. The DN800 sewer is now reinforced with a seamless, jointless "new" pipe capable of withstanding heavy ground loads for decades to come.
