Product Description
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
Conclusion: Durable Infrastructure, Minimal Disruption
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.
