2026-04-02
DN1000 FRPM Pressure Pipeline Rehabilitation
Location: Along main urban road, Yanqing District, Beijing, China
Asset: DN1000 fiberglass reinforced plastic mortar (FRPM) pressure pipeline
Key Project Parameters & Critical Challenges
- Pipeline Type: Pressurized water supply pipeline with severe structural damage
- Operating Pressure: 0.6 MPa rated operating pressure
- Burial Depth: 6 meters underground burial condition
- Adjacent Traffic Corridor: Located immediately adjacent to a major urban arterial road, with strict traffic and construction constraints
- Root Cause of Failure: Pipeline deformation and functional failure caused by grouting works during adjacent main road construction
- Repair Solution: Rapid structural rehabilitation implemented with integrated pre-treatment works to restore pipeline integrity and service performance efficiently
