The invention provides a concrete crack repairing construction technology suitable for high and cold regions. Concrete crack repairing adhesive is heated through a water bath, and then an existing common region concrete crack repairing method is used for repairing the crack on a concrete component; then, thermal-insulation materials are used for wrapping the repaired concrete component in a full-closed mode; next, the thermal-insulation materials are dismantled, and then concrete crack repairing of the high and cold regions is completed. According to the construction technology, the repairing adhesive is heated through the water bath, mixing and stirring of the repairing materials are facilitated, the flowability of the materials is improved, construction is convenient, construction efficiency is improved, the materials are prevented from being rapidly solidified at low temperature, normal solidification is achieved, and the materials can complete solidification and strength improvement well in a highland low-temperature environment. The thermal-insulation measure is adopted, and needed temperature conditions are provided for the repairing materials to guarantee the repairing effect; needed equipment and tools are simple and easy to purchase, the price is low, and implementation is easy.
