In excavator daily homework, digging groove homework is also big 

excavator often do, is also the excavator driver "walk river's lake" 

is one of the essential skills, the next, small make up the drivers 

of heaven and earth, immediately with good talk about how to ditch 

dug this topic.

Before start, need to understand in detail the construction condition, 

understand how to dig, what quality requirement, what it should be noted, 

these common sense for the experienced driver may have a look, the in 

the mind have a spectrum. Also for digging gutter, in advance, 

communicate with the engineer to know which way is the ditch open? 

Which side is the beginning? Which side is the end? Which side needs 

a turn? How wide is dig? Dig deep? And so on and so forth.

Before digging ditches, often construction personnel have already 

put away lime line, drivers and can clearly know the length and 

width of groove and the scope of the working condition of the whole 

sprinkled here good lime line is equivalent to a reference, when 

mining straight hook according to lime line the route of the mining, 

digging the front-end work device using the same trip as far as possible, 

that is to say, each section of the groove digging big forearm and 

bucket with the mining action as consistent as possible, to a certain 

extent, can greatly improve the efficiency and the effect of construction. 

It is best to stop the car to see if the ditch has deviated from the 

required direction, so as to make timely adjustment and save time. 

But in the actual construction process, the lime line is very 

likely to be covered by the earth so that it doesn't play a role, 

so to speak, the question is, how do you dig the trench without 

a lime line?

How do you dig the trench without a lime line?

As the saying goes, there is no problem that can't be solved, but 

there is no way to solve the problem! Spoke of lime in front of 

the line is a reference, since lime line can't see that we have 

to find something else to do reference, it can be a roadside 

kerbstone, also can be the basis of building, but can't find around 

there is no suitable reference, experienced driver excavator crawler 

plate will be as a reference, the little black is also very agree 

with this approach and tried. Adjusting excavator about alignment, 

the edge of the segments as reference, after digging a visual 

groove is straight out of the car, if not flat again, adjust 

the excavator to the appropriate location, the excavator walking 

direction deviation, also don't have as much as possible to keep 

certain actions, one pace reachs the designated position as far 

as possible.

Believe many JiaYou wondering, I'm not straight groove dig is 

bent, but the little black here said the "bend" is not bad, 

but a certain radian turn, need to use bucket bucket teeth or 

edge with the corresponding action to "carve".

Under the direction of the construction personnel, the measuring tool 

can control the depth and the channel slope more accurately, which 

is more the cooperation between the driver and the engineer.

In some time ago, a warm-hearted JiaYou gives us his invention, his 

name is Han Hai, and applied for a patent for this, often around 

real JiaYou should be familiar with this name will be, this is 

accused of "technology" one of the biggest benefits, free time 

can take a closer look at him to write this article, learn about 

his ideas. This is also a way to control the depth of the groove 

when digging ditches, "alone" can "play", this tool looks complicated, 

it doesn't matter, to a complex, is directly with a tape measure 

in the body, the driver next time see can at any time. It may not be 

a tape measure, but it might just be a suitable length of tree branch.

Here after dug trenches, can use the bucket will channel groove end 

flat, the majority of the builder to the requirement of trenching also 

is such, especially in the groove, need to install the pipe groove 

flat after can then proceed to the next step.
