(一) 在平整土地中,如作业区地表高差仅250~300毫米,则推土中很容易出现波浪形土坎,使地推得坑洼不平,影响了工作效率.通过实践,我们认为采用下述方法消除土坎较好.就是在出现波浪形土坎后,把机车调转一个角度,使机车和上铲推土方向夹角为25°~30°.如有两条以上土坎,可把机车停在两条土坎头部、中部或边上,但也要同上次推土方向夹角为25°~30°.然后按平地要领掌握土铲,就可以推平土
(A) In the formation of land, if the surface elevation difference of the work area is only 250-300 mm, the wave-shaped ridge is easy to appear in the soil and the puddles are pushed unevenly, affecting the work efficiency. In practice, we think Use the following method to eliminate the ridge is better.It is in the emergence of wavy ridge, the locomotive to turn an angle, the locomotive and the shovel pushing the direction of the angle between the 25 ° ~ 30 ° .If there are two or more ridge, The locomotive can be parked in the two ridge head, middle or edge, but also with the last push the direction of the angle between 25 ° ~ 30 ° .And then press the ground to grasp the earth shovel, you can push the flat soil
