Let me explain the role of the excavator
Pavement work
Open channel
When the road is to be built, the soil must be first excavated. This work is called the open road trough. The excavator will pick up the soil on both sides, then open the ditch and drain the water. After rolling and drying for a few days through the roller, the first layer of soil is applied. When doing this work, the middle of the roadway should be higher and the two sides should be lower, so as to prevent the water from being in the rain.
When paying attention to the first layer of soil, it is necessary to dig the soil without any soil and grass. If there is a pipeline, it should be layered and crushed several times, and backfilled several times, otherwise there will be a rebound. It is necessary to master the height and depth. Some places are leveled with a grader, but the site where the site is located is leveled with an excavator, and can be directly paved when the soil is reversed on the roadbed.
Mix lime soil
The next step is to mix lime soil. When doing this work, Zhonghua Lifting Network has summarized some tips. Don’t be too embarrassed when working, pay attention to the wind direction, and it is best to deal with it when it is finished. A little, otherwise the bucket is sticky with lime soil and it is difficult to wash off.
There are differences in the construction of roads. In some areas, bulldozers may play a greater role in the entire road construction process, but in some areas, the excavator has replaced many bulldozers for cost reasons. Features. The road construction project described by China Lifting Network can be said to be a typical example of road construction in China, but there are also great differences in different working conditions and different areas in the process of road construction.
Digging pipes
Before the road construction, the pipeline should be buried, and the road should be launched on both sides. While the sewage is on the side of the rain, the work done by the excavator is to grooving and lowering the pipe. This kind of slotting depends on the depth of the ditch. If it is shallow and the soil is good, it can be dug in the vertical ditch, so that the soil is lost and the backfilling is convenient. If the grooves are deeper, it is better to dig them in parallel grooves and excavate them in layers so that the soil will be farther away and avoid landslides.
Generally, the rainwater pipes will be larger and the sewage pipes will be thinner. If the two excavators work together, the work will be done faster. In addition to the grooving work, the excavator is also responsible for the material, the concrete cushion at the bottom of the pipe, and the pipe rim.
