Snow melting method for winter construction
The invention provides a snow melting method for winter construction, which is characterized by comprising the following steps of: containing water with preset mass by using a metal container; heatingthe metal container until the temperature of water in the metal container reaches a preset temperature; adding sodium nitrate into the water reaching the preset temperature, and stirring to form a sodium nitrate solution; pouring the sodium nitrate solution to a construction site of accumulated snow to complete snow melting; the sodium nitrate solution can effectively reduce the freezing point ofsnow water; hot water for melting snow is not frozen after being cooled at negative temperature; even if local freezing is performed at negative temperature, the icing layer is also a thin layer; theformed ice is dispersed and floated on the upper surface of the water in the form of fine particles, is not blocked, can flow along with the water and is prevented from forming ice blocks in the concrete, and in addition, sodium nitrate is a main component in the concrete antifreezing agent and is different from a traditional snow-melting agent containing chloride ions, so that the damage to reinforcing steel bars is prevented, the construction quality is guaranteed, and the construction period is guaranteed.
本发明提供一种冬季施工融雪方法，其特征在于，包括：采用金属容器盛放预设质量的水；加热金属容器直至金属容器中水的温度达到预设温度；向达到预设温度的水中加入硝酸钠，并进行搅拌以形成硝酸钠溶液；将硝酸钠溶液浇至积雪的施工现场上以完成融雪，该硝酸钠溶液能够有效降低雪水的冰点，使化雪的热水在负温下冷却后也不结冰，即使在负温下局部结冰，所结冰层也是薄薄一层，且所结的冰是以细小颗粒分散浮在水的上表面，不成块，可以随水流动，避免在混凝土中形成冰块，此外，硝酸钠是混凝土防冻剂中的主要成份，不同于传统的融雪剂含氯离子，进而防止钢筋受损，保证施工质量且保证工期。
