On July 10, our company successfully applied internationally advanced trenchless repair technology to the Beinie Village section of the Phase I water supply main pipeline, efficiently completing the installation of a 1,200-meter flexible liner hose. This emergency repair employed innovative techniques to ensure residential water safety while minimizing disruption to urban operations.
Core Technological Breakthroughs:
• Intelligent Inspection System: Deployed pipeline robots to scan the entire old pipeline section, clear debris, and precisely locate repair nodes.
• Flexible Composite Liner: Utilized food-grade PE inner lining certified by national standards; pressure testing confirmed perfect adhesion to the original pipeline.
• Mechanized Construction: Employed specialized equipment including flexible shaft hose reels and underwater work vehicles to achieve 72 hours of uninterrupted, high-efficiency operations.
Project Milestones:
• July 10: Completed 1,200-meter hose installation and pressure testing
• July 11 (morning): Initiated pipeline cleaning and disinfection procedures
• July 11 (afternoon): Phased water supply restoration, 8 hours ahead of schedule
This project demonstrates our company's industry-leading technical maturity in trenchless water pipeline rehabilitation. We will continue advancing trenchless technology applications for urban infrastructure maintenance.
