  2. Dewatering - Wikipedia

    en.wikipedia.org/wiki/Dewatering

    On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. This frequently involves the use of submersible "dewatering" pumps, centrifugal ("trash") pumps, eductors, or application of vacuum to well points. The international business research ...

  3. Mine dewatering - Wikipedia

    en.wikipedia.org/wiki/Mine_dewatering

    Where no dewatering techniques were effective the mine had to be shut down due to flooding. [3] In the 15th century mine dewatering techniques made some technical advancements as the first mechanized wooden pumps were used in the German Rammelsberg mine (Lower Saxony), and later in the Ehrenfriedersdorf (Saxony) mines in the 16th century.

  4. Earthworks (engineering) - Wikipedia

    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

  5. Inland Feeder - Wikipedia

    en.wikipedia.org/wiki/Inland_Feeder

    Construction of the tunnel began in October 1998 with the excavation of the Gilman Portal and dewatering work at the two intermediate shafts. Tunnel excavation was carried out from November 1999 through July 2001 using a shielded TBM. Construction of the tunnel included many challenges.

  6. Caisson (engineering) - Wikipedia

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

    Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.

  7. Flooded mine - Wikipedia

    en.wikipedia.org/wiki/Flooded_mine

    Flooding in open pit mines leads to the so-called pit lakes, where a wide range of creatures can be seen. The flooding process happens because the drainage wells or dewatering pumps are stopped and the open spaces are filled with groundwater and surface runoff from precipitation and water bodies (e.g. rivers). Waters quality in flooded open pit ...

  8. Tailings - Wikipedia

    en.wikipedia.org/wiki/Tailings

    Exhausted open pit mines may be refilled with tailings. In all instances, due consideration must be made to contamination of the underlying water table, among other issues. Dewatering is an important part of pond storage, as the tailings are added to the storage facility the water is removed – usually by draining into decant tower structures.

  9. Geotextile tube - Wikipedia

    en.wikipedia.org/wiki/Geotextile_tube

    Geotextile tubes are also installed for land reclamation and temporarily installed during the dewatering phase of a dredging operation. If a geotextile tube is exposed to the elements, it can be vulnerable to bursting.
