防寒保暖措施包括提供暖气设备，在施工场地设置临时板房等，以保证工人的施工环境温暖舒适。
此外，还要加强监控工程质量，确保施工材料的保温性能，避免在冬季施工过程中出现质量问题。
通过合理安排施工工期，避免在恶劣的天气环境下施工，如避免在大风、低温等恶劣气候下开展高空作业。
判断是否进入冬季主要通过天气变化来判断，一般是根据当地气象部门发布的具体日期来确定是否进入冬季。
在实际施工过程中，如果出现明显的降温现象，气温持续低于10度或有霜雪天气，也可判断为进入冬季，需要采取相应的冬季施工措施。
Winter construction measures include taking measures to prevent cold and keep warm, ensuring the quality and safety of construction materials, and scheduling the construction period properly. Measures to prevent cold and keep warm include providing heating equipment and setting up temporary houses at the construction site to ensure a warm and comfortable working environment for workers. In addition, it is necessary to strengthen the monitoring of engineering quality, ensure the thermal insulation performance of construction materials, and avoid quality problems during winter construction. By scheduling the construction period properly, construction activities can be avoided in harsh weather conditions, such as strong winds and low temperatures, in winter. The determination of entering winter mainly relies on changes in weather. Generally, it is determined based on the specific dates announced by the local meteorological department. In actual construction, if there is a significant drop in temperature, with temperatures consistently below 10 degrees or with frost or snow weather, it can also be judged to have entered winter, and corresponding winter construction measures need to be taken.
