Small excavators have large output and high efficiency.Excavators should be selected according to the size of the project and transportation conditions.How to dig trenches with a small excavator?Let's take a look at it together.
1.Before digging trenches,you must do a straight line marking operation to avoid digging deviations.Digging trenches must be straight,which is a very important principle in the process of digging trenches.In order to avoid digging deviations as much as possible,the construction site generally uses lime to set a straight line in advance.The center line of the chassis of the small excavator is aligned with the lime line,and the center bucket teeth of the bucket correspond to the lime line.This can prevent digging deviations.
2.According to the different functions of the trench,different treatment operations are performed on the trench.If the function of this trench is to facilitate the installation of water pipes,the bottom needs to have a certain slope;if it is a foundation pit of a house,the bottom must be level.
3.Do a good job of flatness of the slope.The principle of flatness is the primary factor to ensure that the ditch will not collapse.In the process of trenching,from the beginning of the V-shaped ditch to the end,the slope must maintain the same slope.Of course,the slope must be adjusted accordingly as the soil quality and ditch depth vary.Only when the slope is guaranteed can the trenching effect be better guaranteed.
