  Types of drilled piers in civil engineering ? Types of drilled piers ppt Ø   What is drilled Piers? Drilled piers, also known as caissons, are deep foundation systems used to support structures by transferring loads from unstable soil to stable, deeper soil layers.   v   Types Of Drilled Piers   1)      Straight shaft end bearing pier 2)      Straight shaft side friction pier 3)      Combination pier 4)      Belled pier 5)      Socketed pier 6)      Cased pier 7)      Drilled pier with slurry stabilization 8)      Grouted or pressure injected pier        

  what is caisson? A caisson is a watertight structure that is used as a foundation for buildings and other structures. They are often used in areas with soft or water-saturated soil, or in coastal areas. Caissons are large, hollow cylinders that are made from concrete, steel, or wood.  How caissons are used  Caissons are sunk into the ground until they reach bedrock or stable soil. They are then filled with concrete to create a strong foundation. Caissons are used to support heavy loads. Types of caissons Pneumatic caissons: A watertight box or cylinder-like structure that is closed at the top and open at the bottom.  Box caissons: A box-shaped structure that is closed at the bottom and open at the top.  Monolithic caissons: The largest type of caisson, which are constructed within quay walls.  Benefits of caissons   Caissons are affordable solutions for underwater foundations. They are easy to build and clean. They can be altered according to the spe...
