  2. Trial pit - Wikipedia

    en.wikipedia.org/wiki/Trial_pit

    Trial pits are usually between 1 and 4 metres deep, and are dug either by hand or using a mechanical digger. Building and construction regulations clearly state that any trial pits that concede deeper than 1.2 metres should be secured against structural collapse, if they are to be entered by people.

  3. Deep foundation - Wikipedia

    en.wikipedia.org/wiki/Deep_foundation

    A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site .

  4. Foundation (engineering) - Wikipedia

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

    Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.

  5. 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.

  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. Well drilling - Wikipedia

    en.wikipedia.org/wiki/Well_drilling

    The earliest wells were water wells, shallow pits dug by hand in regions where the water table approached the surface, usually with masonry or wooden walls lining the interior to prevent collapse. Modern drilling techniques utilize long drill shafts, producing holes much narrower and deeper than could be produced by digging.

  8. Steam shovel - Wikipedia

    en.wikipedia.org/wiki/Steam_shovel

    The booming cities in North America used shovels to dig foundations and basements for the early skyscrapers. One hundred and two steam shovels worked in the decade-long dig of the Panama Canal across the Isthmus of Panama. Of these, seventy-seven were built by Bucyrus; [4] the remainder were Marion shovels. These machines 'moved mountains' in ...

  9. Earthworks (engineering) - Wikipedia

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

    In the past, these calculations were done by hand using a slide rule and with methods such as Simpson's rule. Earthworks cost is a function of hauled amount x hauled distance. The goal of mass haul planning is to determine these amounts and the goal of mass haul optimization is to minimize either or both. [2]
