Water Supply Box Culvert Rehabilitation
Location: Zhuzhou, China
Asset: Potable water supply box culvert
Key Project Parameters & Challenges
- Target Defect: Expansion joint leakage repair (critical targeted patching for severe leakage points)
- Operating Pressure: 0.4 MPa pressurized running condition
- Dual Parallel Channel Layout: One channel in service while the other undergoes repair to ensure uninterrupted water supply
- Severe Culvert Leakage: Widespread leakage issues concentrated at expansion joints, requiring precision targeted remediation
- Pressurized Operational Constraint: Repairs performed under stable 0.4 MPa operating pressure without full system shutdown
