Minimizing Shut Down during Repair of PCCP
During construction of an interconnection between two 48 in. water transmission lines in Houston, Texas, severe distress was visually noted within a section of existing 48-in. prestressed concrete cylinder pipe (PCCP). The distress was noted by intersection longitudinal and circumferential cracking and an audible hollow sound in the concrete core. The distress also fell directly below a recently installed large diameter storm sewer. Due to time constraints at the time, an immediate repair was not feasible, but the City made plans for a future repair. The City analyzed multiple repair methods, including remove and replace, internal methods such as sliplining and carbon fiber, and external methods such as encasement, bolted clamps, and post-tension cables. This paper will describe the evaluation of repair methods, issues with shutting this particular line segment down for an extended repair, and construction of the selected method post-tension cable reinforcement.
