1. The trench must be dug straight.
Digging ditches basically follows the principle of straight digging. Generally, the route of the lime ditch is 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 of the bucket correspond to the lime line, so that it is not easy to dig out of the way.

If there is no lime line, you can use the track to press out a connecting line first, and the track traces left can play the role of the lime line. Bucket motion can then be adjusted to the track print left by backing up.

2. The surface layer should be opened first.
When formally excavating, first take the surface layer, and then remove the lower layer. Never dig to the bottom at one time, especially the excavation of deep trenches is especially important; when digging a trench larger than the width of the bucket, first dig both sides, and then Dig in the middle.

3. Maintain the flatness of the slope.
Many novices are not good at digging ditches, mainly because they have not done the principle of neatness, and the detailed operation needs to be further improved. From the beginning of opening the V-shaped ditch to the end, the slope must be kept the same. Of course, the soil quality and the depth of the ditch are different, and the slope needs to be adjusted accordingly.

4. Control of the bottom of the ditch.
The control of the bottom of the ditch is very important. At this time, it is necessary to use the skills of throwing squares and leveling. If the trench is to install water pipes for drainage, a certain slope at the bottom is required. If it is a house foundation pit, the bottom level is required.
In fact, many operators are not sure about the height of the bottom of the ditch. When there are surveyors, they can ask the construction workers to measure with instruments and measure while digging. If you don’t have any, you can find some references, and you should get out of the car to observe more.
