Deep excavations are often required for the construction of structures like metro station boxes, basements, underground car parks, water and sewer shafts, and caissons.  Here are some types of deep foundations: Pile foundation: A deep foundation that uses vertical timber, steel, or concrete to support loads at a low level. Caisson: A sturdy, watertight structure built above ground level and then sunk into the ground. Caissons can be made of wood, steel, or reinforced concrete. Drilled pier: A large-diameter pile that can be a type of pier foundation.  The types of caissons... Show more

Deep excavations are often required for the construction of structures like metro station boxes, basements, underground car parks, water and sewer shafts, and caissons. 

Here are some types of deep foundations:
Pile foundation: A deep foundation that uses vertical timber, steel, or concrete to support loads at a low level.
Caisson: A sturdy, watertight structure built above ground level and then sunk into the ground. Caissons can be made of wood, steel, or reinforced concrete.
Drilled pier: A large-diameter pile that can be a type of pier foundation. 

The types of caissons include: 
Box, Open, Pneumatic, Monolithic, Floating, Excavated.

 

Deep Excavations, Pile Foundations and Caisson topics include: Timbering terms, well point system, dewatering of foundation trenches, pile different types, pile driving formulas, caissons classification, cofferdam and caisson.
