Before trimming the slope, the blade should be adjusted to tilt to the left or to the right. The adjustment method can be referred to (the adjustment method for different job requirements of the grader blade).
When repairing the side slope, the scraping angle should be smaller; when repairing the roadbed slope, the roadside slope, the dam slope or the ditch, the scraping angle should be larger; when repairing the vertical slope of the cliff, the scraping angle Can be adjusted to 90o. However, it should be noted that the height of the cliff should not exceed the length of the blade to prevent the soil from collapsing and damage the machine noise.
For slopes with a slope of 34o-64o and a width less than the length of the grader blade, the grade can be completed with a grader. The soil that has been scraped off can be removed by the scraping side shifting method.
For slopes with a slope width greater than the length of the grader blade, two graders are required to work together, as shown in Figure 3b. One is scraping down on the road, and the other is shaving on the side of the roadbed. At the beginning, the upper one should be about 10m, and then the next one will start work. In this way, the soil scraped from the top does not affect the work under the dyke. At the same time, the operator of the grading machine can connect the two working faces into one complete shape according to the shape of the slope that the grading machine has been scraped. The slope of the bevel.
