  2. Screw piles - Wikipedia

    en.wikipedia.org/wiki/Screw_piles

    Screw piles are typically manufactured from high-strength steel [1] using varying sizes of tubular hollow sections with helical flights. The pile shaft transfers a structure's load into the pile. Helical steel plates are welded to the pile shaft to suit the site specific ground conditions. Helices can be press-formed to a specified pitch or ...

  3. Deep foundation - Wikipedia

    en.wikipedia.org/wiki/Deep_foundation

    When used in permanent works, these walls can be designed to resist vertical loads in addition lateral load from retaining soil. Construction of both methods is the same as for foundation bearing piles. Contiguous walls are constructed with small gaps between adjacent piles. The spacing of the piles can be varied to provide suitable bending ...

  4. Tieback (geotechnical) - Wikipedia

    en.wikipedia.org/wiki/Tieback_(geotechnical)

    Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]

  5. 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.

  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. Inverted arch - Wikipedia

    en.wikipedia.org/wiki/Inverted_arch

    Inverted arches are often used in conjunction with retaining walls. The arch provides a foundation for the walls and can resist the sideways forces upon them. The retaining wall also provides the vertical load needed by the arch. They are also used as foundation for the piers in order to distribute the load over the area between the piers. [4]

  9. Retaining wall - Wikipedia

    en.wikipedia.org/wiki/Retaining_wall

    Bored pile retaining wall in Lisbon, Portugal. Bored pile retaining walls are built by assembling a sequence of bored piles, followed by excavating away the excess soil. Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and shotcrete reinforcement layer.
