What do you know about the skills of small excavator slope repair and road repair?

1. Determine the distance between the top and bottom of the slope

Before starting to repair the slope, first observe the span and the distance between the upper and lower ends of the slope to be repaired, to determine the size of the slope to be repaired. If an uphill and downhill path opens directly from a step, the length and size of the slope depends on the height of the step. The higher the step height, the longer the slope (of course, it must be determined according to the actual environment on the site determines the length of the slope).

2. The rudiment of repairing the outlet with an excavator.

After deciding the slope of the road to be built, start digging with an excavator. First, join layers from the top of the slope down so that the earthworks at the top of the slope can join the bottom to raise the bottom surface of the road and reduce the grade of the entire road. . When the slope is collected from the top to almost the middle, use a bucket to spread the collected soil to the bottom, and the general outline of the entire road surface will have been formed.

3. Leveling ramps

When the slope is more or less formed, we will level the road surface of the ramp. Still from the top end of the slope, use a bucket to bring down the raised parts and cover up the sunken places (of course, experienced operators can usually form them at the same time), if there is only a small amount of loose soil and stone on the slope. soil that needs to be processed Leveling, we can use the excavator to rotate to "sweep" the soil and rocks. It should be noted that the rotational force will be relatively small. When encountering hard ground or a lot of ground, it will not be "swept away". At this time, multiple The combination of compound movements sweeps the soil layer.

When the turning force is insufficient and the bucket is "stuck" there, we can use the forward and backward contraction of the forearm and the small opening and closing of the bucket to reduce the resistance of the bucket, thus "sweeping" the hard drive. floor. In this way, when the road surface is relatively flat, use the excavator track belt to walk back and forth on the entire road surface for a few times, and use the track belt to compact the surface. Of the road.
