  2. Retaining wall - Wikipedia

    en.wikipedia.org/wiki/Retaining_wall

    Cantilevered retaining walls are made from an internal stem of steel-reinforced, cast-in-place concrete or mortared masonry (often in the shape of an inverted T). These walls cantilever loads (like a beam ) to a large, structural footing, converting horizontal pressures from behind the wall to vertical pressures on the ground below.

  3. Continuous flight augering - Wikipedia

    en.wikipedia.org/wiki/Continuous_flight_augering

    Continuous flight augering can be used to construct a secant piled wall which can be used as a retaining wall or as shoring during excavation. Once initial piles are set with concrete, other shafts are augured between them, slicing into the original piles, with the new ones receiving rebar .

  4. Revetment - Wikipedia

    en.wikipedia.org/wiki/Revetment

    Asphalt and sandbag revetment with a geotextile filter. A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion.

  5. Lateral earth pressure - Wikipedia

    en.wikipedia.org/wiki/Lateral_earth_pressure

    An example of lateral earth pressure overturning a retaining wall. The lateral earth pressure is the pressure that soil exerts in the horizontal direction. It is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations and ...

  6. Mechanically stabilized earth - Wikipedia

    en.wikipedia.org/wiki/Mechanically_stabilized_earth

    The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing ...

  7. Ecology block - Wikipedia

    en.wikipedia.org/wiki/Ecology_block

    When constructing a retaining wall from eco-blocks, a stable foundation is still required. In July 2015, a 70-year-old man in Washington died after an ecology block wall under construction on a sand foundation collapsed, and his legs were crushed by a 3,600-pound (1,600 kg) block. [1] [12]

  8. Earthworks (engineering) - Wikipedia

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

    In that case, earthwork software is principally used to calculate cut and fill volumes which are then used for producing material and time estimates. Most products offer additional functionality such as the ability to takeoff terrain elevation from plans (using contour lines and spot heights ); produce shaded cut and fill maps; produce cross ...

  9. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
