在我国北方,冬季和初春每年降雪期约有3～5个月,东北、西北、华北广大地区几十万公里的道路存在除雪问题。道路上的积雪给交通运输带来较多的困难:雪层加大了车轮的滚动阻力,增加了燃油消耗,大雪还能堵塞道路,中断交通,即使是在一般雪层行驶的车辆,运输效率和交通安全都受很大的影响。因此,研究和发展我国的道路除雪机械是十分必要的。
In northern China, the annual snowfall period in winter and early spring is about 3 to 5 months. There are snow removal problems in the roads of northeast, northwest and north China over a large area of hundreds of thousands of kilometers. Snow on the road brings more difficulties to transportation: the snow layer increases the rolling resistance of the wheel, increases the fuel consumption, heavy snow can block the road, interrupt the traffic, and even the vehicles running in the general snow layer, the transportation Efficiency and traffic safety are greatly affected. Therefore, it is very necessary to study and develop the road snow removal machinery in our country.
