Excavator trench digging skills!

For a lot of excavators , general excavation is not difficult , but many complex conditions such as hoisting , crushing , stone , brush broken and other engineering , it is difficult to start , the key points are as follows :

1. Dredging operations  

Rid the two tracks of the excavator in the middle of the ditch,The method of back walking is to stretch the arms and arms in the right position. The back of the shovel is placed in the dirt at a 30 ° angle with the ground. According to the looseness of the soil, determine the speed of stretching the arms. According the amount of dirt in the shovel, make a composite roll, and then turn the dressing.

2. Fixtures    

First use a shovel to disperse most of the dirt evenly and hook it flat with the teeth of the shovel. Then put the shovel on the back.
Parallel to the ground, keep the ground near contact with the back of the fighting, stretch out the arms, roll the shovel, lift and lower the arms in a continuous compound motion, while also turning to clear excess dirt and walking back.

   3 , excavator hoisting operation

Hydraulic excavator lifting operation, should confirm the lifting site around the situation, the use of high-strength hook and wire rope, lifting should try to use a dedicated lifting device；The mode of operation should choose microoperation mode, and the actions should be slowly balanced; The length and length of the rope should be appropriate; excessive length will make the suspension swing larger and difficult to control precisely; The shovel position should be correctly adjusted to prevent the steel line from getting off;Construction personnel should try not to be close to the hoisting object to prevent improper operation of the danger.

Control of the bottom of the ditch. Control of the bottom of the ditch is crucial, and this is a time when you need to apply the techniques of slashing sides and finding flats. If the trench is dug for the purpose of installing a water pipe for drainage, it needs to have a certain slope at the bottom; If it's a building foundation pit, the bottom level is required. In fact, many operators cannot see the height or low of the bottom of the ditch, and when there are surveyors, the construction worker can be asked to measure through the instrument and survey while digging. There are times when you can find some reference, and you should get out of the car and watch.

Three Ways to Dig a Gap

The above has briefly explained the basic operational techniques for digging a ditch. Finally, we will introduce you to three ways of digging these ditches:

(1) Riding: mainly in open areas of the site, the diggers are parked in the middle of the trench to be dug, and the shovel is dug between two tracks.

(2) Side-by-side: This refers to areas of a relatively narrow field, such as a clearing, where the shovel is dug only along one side of the track line (this requires the technique of side slopes).

(3) Positive method: mainly for road culvert digging, which means that the diggers are placed in 90 degrees opposite the edge of the ditch (it is important to note that the fuel tank of the shovel may touch the edge of a ditch when it is deeper).

In short, the machine hand in the process of digging trenches need to pay special attention to dig straight, slope level up degree, control of the bottom of the ditch, etc., choose the right way of trenching, in fact, trenching is not difficult.
