How does a mini excavator dig trenches?

Small excavators have a large output and high efficiency. The excavator should be selected according to the size of the project and transportation conditions. How to use a small excavator to carry out trenching work? Let's take a look together below.

1. Before digging the trench, do a good job of straightening the line to avoid the problem of digging deviation. Digging trenches should be straight. This is a very important principle in the process of trenching. In order to avoid digging deviation, a straight line is usually set in advance with lime on the construction site. The center line of the chassis of the small excavator is aligned with the lime line, and the middle of the bucket The bucket teeth correspond to the lime line, which can avoid digging deviation.

2. According to the different functions of the ditch, carry out different treatment work on the ditch. If the function of this ditch is to facilitate the installation of water pipes, it needs a certain slope at the bottom; if it is a house foundation pit, the bottom is required to be level.

3. Do a good job of leveling the slope. The principle of flatness is an important factor to ensure that the ditch will not collapse. In the process of digging the ditch, from the beginning of the V-shaped ditch to the back, the slope must maintain the same slope. Of course, the soil quality and the depth of the ditch are different, and the slope is also different. It needs to be adjusted accordingly, and the slope is guaranteed, so as to better ensure the trenching effect.
