Repair of underground buried pipes with resin transfer molding

摘要

Repairing and replacing of worn-out underground pipes, such as sewer pipes, water-supply pipes, gas pipes, and communication cables by excavating not only cause traffic congestion but also produce large amount of waste. Also, the operation requires heavy equipments and longer operating time and high cost. In this study, the repairing-reinforcing process of underground pipes with glass fiber fabric polymer composites using resin Transfer molding (RTM) which overcomes the problems of present trenchless technologies has been developed.
