There are many quality and safety risks in winter construction of water-sealed caves in cold areas. To ensure construction quality and operation efficiency, a series of insulation measures are adopted according to the actual conditions on site. This paper makes special in-depth elaboration on the technical feasibility, safety and environmental friendliness and economic applicability of the selection of heating energy, the calculation of heat power consumption, the use of materials and equipment, and the application of heating system quality standards, assurance measures and inspection methods, etc. for winter construction standards and management. It turns out that such measures effectively ensure normal construction.
