This paper mainly introduces the working principles and construction steps of hydraulic pipe-fracturing technology. Combining with the construction case in Changchun sewage pipeline replacement, the detail exposition are given to the construction steps, the difficult problems and treatment measures as well as the construction precautions for the application of the hydraulic pipe-fracturing technology in sewage pipeline in-situ replacement. In this construction, hydraulic pipe-fracturing technology showed its unique advantages with good effects, the experience can be reference to the trenchless pipe replacement.
