1. High environmental adaptability requirements: The low-temperature conditions in frigid regions impose stringent demands on material weather resistance and construction techniques;

2. Difficult construction logistics: Mountainous terrain combined with high-altitude reservoir settings creates significant challenges for transporting primary materials and equipment;

3. Complex pipeline pretreatment: Aquatic organisms present within pipes necessitate pulse cleaning technology for removal;

4. Water pressure compatibility: Ensuring restored seal integrity under 1.6MPa high-pressure operating conditions.

1. Achieved the first application of flexible composite hose repair technology in reservoir scenarios;

2. Overcame challenges in repairing water supply pipelines in frigid regions, validating the technology's environmental adaptability;

3. Ensured the safety of raw water conveyance for elevated reservoirs, providing a reference for similar projects in the Northeast Plateau Plain.

Leveraging advanced restoration technology, we have successfully overcome the industry-wide challenge of repairing water supply pipelines in high-altitude reservoirs within frigid regions, ensuring stable delivery of raw water from critical water sources. As a trusted technical partner, we have provided invaluable experience for similar pipeline restoration projects in Northeast China's cold regions! — Reservoir Management Office
