This article conducts research on the feasibility and power selection of winter electric heating construction for prestressed pipeline grouting. A thermodynamic numerical calculation model for the hydration process of cement in prestressed corrugated pipes was constructed, and the temperature variation and spatial distribution in the pipeline under heating conditions in a low-temperature environment were studied. The relevant results provide data support for the winter construction of prestressed pipelines.
