An important component of civil engineering utilised while building bridges, docks, etc. is the caisson foundation. The word caisson is derived from the Latin capsa, which denotes a box or material resembling a box.<\/yoastmark> The pier foundation is another name for the caisson foundation. It serves as a bridge pier and is a watertight water barrier. It is a prefabricated hollow box or cylinder that is filled with concrete, sinks into the ground to a certain desirable depth, and serves as the foundation.<\/yoastmark><\/p>\n

Although caisson foundations are placed differently than pile foundations, they are comparable in shape.<\/yoastmark> It is employed when suitable bearing-strength soils are discovered below weak surface materials like peat or backfill.<\/yoastmark> Various caisson foundation types, uses, and other important details are discussed here.<\/yoastmark><\/p>\n

Caisson Foundation : Purpose<\/strong><\/h2>\n

Occasionally, a caisson foundation is use.<\/yoastmark> Here they are.<\/p>\n

    \n
  • If you need a strong undercarriage that reaches up to or below the back deck to resist damaging forces from floats, cuts, etc., a caisson foundation is employ when the ground contains substantial rocks that prevent the pile from penetrating the surface.<\/yoastmark><\/li>\n
  • Whenever the foundation is subject to a sizable lateral load<\/yoastmark><\/li>\n
  • when a deep river or sea<\/li>\n
  • If luggage needs to be carry at the end and the load arrangement involves flow forces, caissons are chosen.<\/yoastmark><\/li>\n
  • If the current groundwater table is actively inflowing, caissons are a wise choice.<\/li>\n<\/ul>\n

    Examples of a caisson foundation<\/strong><\/h2>\n

    There are various caisson foundation types. Here are some of them:<\/p>\n

    Box caissons:<\/strong><\/h3>\n

    These are heavy, wooden boxes that are watertight and open at the top. They are normally float to an appropriate location, where they are then place into position using a masonry pier.<\/p>\n

    Excavated caissons:<\/strong><\/h3>\n

    Caisson foundations that have been excavate are position within an unearth area. Typically cylindrical, they are subsequently backfill with concrete.<\/p>\n

    Floating caissons :<\/strong><\/h3>\n

    These are also refer to as floating docks and construct cylindrical boxes.<\/p>\n

    Open caissons:<\/strong><\/h3>\n

    Comparable to box caissons in many ways. High and low, open, and high open-low close are the two variations of open boxes. These caissons are best suit to soft terrain.<\/p>\n

    Pneumatic caissons:<\/strong><\/h3>\n

    These are sizable, waterproof containers or cylinders that are mostly employ in the construction of submerge structures.<\/p>\n

    Compressed air caissons:<\/strong><\/h3>\n

    This sort of box is appropriate for dry working environments where other techniques won’t function effectively.<\/p>\n

    Monolithic caissons:<\/strong><\/h3>\n

    This is the biggest type of caisson foundation.<\/p>\n

    Uses for the Caisson foundation<\/strong><\/h2>\n
      \n
    • Transfer weight from building columns and bridge piers to the hardest subterranean layer.<\/li>\n
    • Earthen dams with caissons set closely together have unbreakable core walls.<\/li>\n
    • to create room for tunnels or deep shafts.<\/li>\n
    • Build any barriers that would prevent the submersion of machinery, pumps, etc.<\/li>\n
    • to safeguard the base against lateral stresses.<\/li>\n<\/ul>\n

      Caisson foundation: benefits<\/strong><\/h2>\n
        \n
      • reduces the necessity for post caps.<\/li>\n
      • It generates a little less vibration and noise.<\/li>\n
      • able to quickly adjust to any changing field conditions.<\/li>\n
      • high capacity for axial and lateral loads.<\/li>\n<\/ul>\n

        Caisson foundation: drawbacks<\/strong><\/h2>\n
          \n
        • It is quite susceptible to construction techniques.<\/li>\n
        • Legacy assets should not use it.<\/li>\n
        • The construction can only be design by experience engineers. There is a shortage of professionals.<\/li>\n
        • It puts workers in a dangerous environment where they could contract caisson illness.<\/li>\n
        • Inspectors who are qualified are in short supply.<\/li>\n<\/ul>\n
