我国地域广阔,地跨热带、亚热带和温带,其中温带约占国土总面积的三分之一左右。这些地区每年都有不同程度的降雪,尤其是在纬度较高的北方地区,每年的降雪都在4个至6个月之间,几十万公里的公路都存在着清除积雪的问题。降雪及公路上的积雪,给人民生活带来一定的困难,极易诱发交通事故。尤其在高速公路上,因积雪或融雪结冰而使高速公路被迫封闭停运,造成极大的经济损失。目前国内除雪方式主要有人工除雪、机械除雪、撒铺融雪剂除雪三种。
Our country has a vast territory spanning tropical, subtropical and temperate regions, of which the temperate zone accounts for about one third of the total land area. There are varying degrees of snowfall in these areas each year, especially in the northern latitudes where the annual snowfall is between 4 and 6 months. There are problems with snow removal in the hundreds of thousands of kilometers of highways. Snowfall and snow on the road have brought some difficulties to people’s lives and can easily lead to traffic accidents. Especially on the expressway, the freeway is forced to close and shut down due to snow dripping or snowmelt freezing, resulting in enormous economic losses. At present, there are three methods for snow removal in China, such as manual snow removal, mechanical snow removal and snow removal and snow removal.
