That is to say, when excavating each section of trench, the excavation actions of the big and small arms and the bucket are as consistent as possible, which can greatly improve the work efficiency and construction effect to a certain extent.
For any slope, the top and bottom edge lines must be determined first. Brush the slope flat to highlight the top line and increase the aesthetic feeling, and brush it into a straight plane from top to bottom, which is especially important in the reference template at the beginning of slope brush.
For slopes with a height greater than that of the excavator arm, the slope operation can be carried out first, and then the slope bottom operation can be carried out. If conditions permit, the machine can dig in the slope, which is often used in ordinary embankment operations.
Extended data:
Before starting work, you should know the detailed construction situation, how to dig, what requirements the constructor has and what to pay attention to. For experienced drivers, this common sense may have a spectrum when considering working conditions. Similarly, we should communicate with the construction party in advance to find out which direction the ditch should be opened. Which side is the beginning? Which side is the end? Which side needs to be transferred again? How wide is the excavation? How deep did you dig? And so on all need to understand.
The most basic thing in trenching is to follow the principle of straightening. The route of lime ditch is usually drawn on the construction site. The center line of the chassis of the excavator is aligned with the lime line, and the bucket teeth in the middle correspond to the lime line, so it is not easy to dig.
When formally excavating, the surface layer should be taken first, and then the lower layer should be taken. Never dig to the end at one time, especially deep trench excavation. When digging a ditch wider than a bucket, dig both sides first, and then dig the middle. ?
Many novices can't dig trenches well, mainly because there is no neat principle, and the detailed operation needs to be further improved. The slope of V-shaped ditch should be consistent from the starting point to the end point. Of course, the soil quality and ditch depth are different, and the slope needs to be adjusted accordingly.
