In the course of excavation, many different hand tools are used and no less than the varieties of technology. Of the most popular manual tools, you can distinguish a pick, a manual drill and of course a bayonet shovel. As for heavy equipment, these are drills on wheels and excavators.
Earthwork performed by manual instruments, as a rule, do not differ in large volumes, which not to say about the work of those leading with the help of the same excavators.
It is important to note that the nature of the soil is largely affected by the type of soil so if the soil is normal, then in the process of its development the same excavator based on a conventional tractor and a regular bayonet shovel can be used. But if this is, for example, rocky soil, which does not even take the shovel, in which case, special techniques and the same special tools are used, in the role of which vibrators, picks and much more are act. In the development of rocks, explosives are often used often. First, a small hole is made in the right place, then explosives are laid in it with a subsequent explosion.
