摘要

The "El Encanto" power plant, 75 miles northwest of San Jose, Costa Rica, conveys river water from an upstream dam to the turbine complex downstream. The pipeline is built of cast-in-place reinforced concrete, with an inner diameter of 7 ft, and a total length of 5,742 ft. But upon being put into service, the pipeline developed cracks resulting in a 20 percent decrease in flow that rendered the plant inoperable. After other repair methods failed, QuakeWrap was contacted for engineering consultation and a repair using fiber-reinforced polymer was developed.
