在我国林区公路工程的准备作业及路基土方填挖工作中,常使用Д-271型推土机。由于林区自然条件的关系,推土机的作业地段,大部分选在地表干燥,地下水位低,土壤多为砂砾土的地段。在土方集中且运距大于一公里以上时,用推土机集土装车,以汽车或轨道斗车运土的联合作业,收到了良好的效果。具体运用如下:一、推土机作业地段的准备工作气候寒冷的林区,推土机的工作期间一般只能从5月中旬至10月中旬。为了充分利用这一有限的时间,进行推土机作业,做好准备工作是很重要的。在
In our country forest road preparation work and subgrade earthwork filling work, often use Д-271 bulldozer. Due to the natural conditions of the forest area, bulldozers work area, most of the election in the dry surface, groundwater level is low, the soil is mostly gravel soil lots. When earthwork is concentrated and the distance is more than one kilometer, a good result has been achieved through the joint operation of earth loading and loading with a bulldozer and transporting soil with a car or rail car. The specific use of the following: First, bulldozers work area preparation work Cold forest, bulldozers during the general work only from mid-May to mid-October. In order to take full advantage of this limited time, bulldozer operations, preparation is very important. in
