    en.wikipedia.org/wiki/Digging

    An excavation lake (also a flooded gravel pit) is an artificial lake, which usually has its origins in the excavation of gravel or sand for construction materials or in some other kind of surface mining. In many cases, the excavation holes are landscaped according to the land restoration required by law.

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

    Earth moving equipment (c. 1922) Flattened and leveled construction site. Road roller in the background. Excavation may be classified by type of material: [1]: 13.1 Topsoil excavation; Earth excavation; Rock excavation; Muck excavation – this usually contains excess water and unsuitable soil

  4. Tunnel construction - Wikipedia

    en.wikipedia.org/wiki/Tunnel_construction

    Tunnel Construction. Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management.

  5. Drilling and blasting - Wikipedia

    en.wikipedia.org/wiki/Drilling_and_blasting

    Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.

  6. Excavator - Wikipedia

    en.wikipedia.org/wiki/Excavator

    Excavators are heavy construction equipment primarily consisting of a boom, dipper (or stick), bucket, and cab on a rotating platform known as the "house". [ 1 ] The modern excavator's house sits atop an undercarriage with tracks or wheels , being an evolution of the steam shovel (which itself evolved into the power shovel when steam was ...

  7. Archaeological excavation - Wikipedia

    en.wikipedia.org/wiki/Archaeological_excavation

    Archaeological excavation is an unrepeatable process, since the same area of the ground cannot be excavated twice. [24] Thus, archaeology is often known as a destructive science, where you must destroy the original evidence in order to make observations.

  8. Highway engineering - Wikipedia

    en.wikipedia.org/wiki/Highway_engineering

    Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.

  9. Ground freezing - Wikipedia

    en.wikipedia.org/wiki/Ground_freezing

    Soil contaminated with radioactive elements that leaked from Japan's Fukushima Daiichi nuclear power plant was contained through ground freezing. [1]A project in Boston known as the Big Dig used ground freezing during some of its tunneling, to allow its wide tunnels to be built under or through soil that supported existing infrastructure that would have been difficult or expensive to support ...
