The Functions of the Used Excavators in Road Building

Tags: used Komatsu excavator competitive used excavator2013-11-21

Road building is one of the most common projects in engineering machinery. And excavators play an important role in it. Actually, its functions depend on where it is. Actually, the bulldozer plays a more important role in road building. However, take the cost into consideration, some areas replacing bulldozers with excavators. Actually, the bulldozer plays a more important role in road building. However, take the cost into consideration, some areas replace bulldozers with excavators, especially the used excavators.

The most important work that the used excavators do in road building is to excavate pipelines. It is needed to bury pipelines and build sewers before road building. And what the excavators need to do is to slot and bury the pipes. The slot depends on the depth of the gutter. If the gutter is shallow and has good soil property, and it can be excavated in a vertical way, then the excavators can throw the earth close to the gutter, which is beneficial to backfill. And if the gutter is deep, it is better to choose a parallel way.

Though hierarchical excavating, the earth can be thrown a little far to avoid collapse. In general, rain pipe is much larger than sewage pipe. The work will be done quickly if there are two used excavators working coordinated with each other. And except for slotting, the excavators are also responsible for the concrete cushion at the bottom of the pipes and their surrounding edges. The excavators throw the earth to the both sides of the gutter and proceed with draining. After grinding by steamroller and sun-cure for several days, the first floor earth should be paved. In the process of this, the center of the slot should be higher than the both sides of it to avoid gathering water on the surface of the road.

When paving the first floor earth, some problems should pay attention to. First, there should not be mixed soil and grass during excavating. Second, the place where pipelines needed to be passed through should be grinded and backfilled for several times, or the rebounds will appear.
