Power Plant Storm Water Pipe Strengthening
- Installation of a custom designed and supplied CFRP system
- Training mockup for pipe installation performed
- Completed in four months
- Contractor: PULLMAN
- Design & Material Supply: STRUCTURAL TECHNOLOGIES
A coal-fired power generation facility in the United States had a storm water pipe running below operational areas of the plant and was showing signs of deterioration in the pipe interior. When localized failures started to appear, the owner proactively developed a repair program to repair the pipe to prevent the release of environmentally hazardous materials into the nearby river systems.
PULLMAN and STRUCTURAL TECHNOLOGIES teamed to design a carbon fiber reinforced polymer system (CFRP) for the repair solution. A mock-up of a five-foot pipe section was built to train personnel and used for preplanning the installation of the shoring towers, preplanning the manhole capping, training the crew on CFRP installation procedures, and for safety-related exercises.
Shoring was installed to support pipe sections during joint repairs and installation of the CFRP system. PULLMAN crews performed partial joint demolition, plugged the legacy manhole access in the upstream pipe, and repaired 160-feet of the upstream section of the pipe. PULLMAN crews installed STRUCTURAL TECHNOLOGIES’ custom designed V-Wrap™ Carbon Fiber System in certain pipe sections.
