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. Fracking - Wikipedia

   en.wikipedia.org/wiki/Fracking

   Fracking (also known as hydraulic fracturing, fracing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of ...

4. Digging - Wikipedia

   en.wikipedia.org/wiki/Digging

   Digging. A dog digging on a beach. 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 ...

   A mass haul diagram where land and rock cuts are hauled to fills Fill construction in 1909 Cut and fill software: view from above. In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments to minimize the amount of construction labor.

   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 ...

   en.wikipedia.org/wiki/Mechanically_stabilized_earth

   Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls , bridge abutments, seawalls , and dikes . [ 1 ] [ 2 ] Although the basic principles of MSE have been used throughout history, MSE was developed in its current form in the 1960s.

8. 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.

9. Grading (earthworks) - Wikipedia

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

   Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage. The earthworks created for such a purpose are often ...
