2. Earthworks (engineering) - Wikipedia

   en.wikipedia.org/wiki/Earthworks_(engineering)

   In military engineering, earthworks are, more specifically, types of fortifications constructed from soil. Although soil is not very strong, it is cheap enough that huge quantities can be used, generating formidable structures. Examples of older earthwork fortifications include moats, sod walls, motte-and-bailey castles, and hill forts.

3. Digging - Wikipedia

   en.wikipedia.org/wiki/Digging

   Digging, also referred to as excavation, is the process of using some implement such as claws, hands, manual tools or heavy equipment, to remove material from a solid surface, usually soil, sand or rock on the surface of Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the ...

   Dragline excavator. Built by Bucyrus-Erie in 1969, Big Muskie was the world's largest ever dragline, being 487 ft (148 m) in length, weighing some 13,500 short tons (12,247 t), and hoisting a 220 cu yd (168.2 m 3) bucket that could move 325 short tons (295 t) of material at a pass. A dragline excavator is a heavy-duty excavator used in civil ...

7. Cut (earthworks) - Wikipedia

   en.wikipedia.org/wiki/Cut_(earthworks)

   Cut (earthworks) Road cutting. In civil engineering, a cut or cutting is where soil or rock from a relative rise along a route is removed. The term is also used in river management to speed a waterway's flow by short-cutting a meander . Cuts are typically used in road, rail, and canal construction to reduce the length and grade of a route.

8. Suction excavator - Wikipedia

   en.wikipedia.org/wiki/Suction_excavator

   Description. Suction excavation utilizes high-powered fans to safely excavate up to 141 feet (43 meters) of depth depending on the configuration. First, a small surface area hole of about 10 inches (250 mm) is created. Then, the suction excavator hose removes materials below the surface. Compressed air is used to fracture the ground for the ...
