机械修路时常用的土方机械有:挖土机、铲土升运机、平地机、自动平地机、推土机和铲运机等。前四种以从路基两侧取土就近填筑,才能发挥最大效力,且路堤高度一般不超过1.5米。推土机以推送100米以内的土方为宜。而铲运机既适合于路侧取土填筑,又可以铲运运距1公里左右的土方直接填筑较高的路堤,并且根据运距的远近,使路基土方达到部分或全部的压实。由于它的这些优点,所以在国内外筑路工程中被广泛地采用。
Earthwork machinery commonly used in mechanical road construction are: excavators, shovel loaders, graders, graders, bulldozers and scrapers. The first four to take soil from both sides of the embankment near the filling, in order to maximize effectiveness, and the embankment height is generally not more than 1.5 meters. Bulldozers to push the earth within 100 meters is appropriate. The scraper is not only suitable for roadside filling and filling, but also can be shoveling about 1 km away from the earth directly fill the higher embankment, and according to the distance of the distance, make subgrade earthwork to achieve some or all of the compaction . Because of these advantages, it is widely used in road construction at home and abroad.
