Types of Pile Foundation, Factors Affecting Selection of Pile Foundation Type, What is Friction Pile? Piles are driven into surface condition. Caissons are large width foundations which carry the load of the superstructure through a layer of weak soil to firm stratum at considerable depth. Caisson is putting a box into underwater and pouring it with concrete. Caissons have a relatively large load bearing capacity. Pile is a column of material driven by a piledriver. In addition, you may be able to forego pile caps because the caissons are already filled with concrete. Both a caisson and a 3×3 pile foundation are considered as suitable design options. Caissons can be installed in most soil types and can be drilled into sound bedrock. Piles may be either driven or cast in place. Also called caissons, drilled shafts, drilled piers, cast-in-drilled-hole piles (CIDH piles) or cast-in-situ piles, a borehole is drilled into the ground, then concrete (and often some sort of reinforcing) is placed into the borehole to form the pile. link. Pile is a column of material driven by a piledriver. Pile, pier and caisson foundations are three different types of deep foundation used in construction. The types of pier foundations are masonry or concrete piers and drilled caissons. Caissons, also known as drilled shafts, are high-capacity, cast-in-place deep foundation elements designed with steel reinforcement to primarily resist the compressive, uplift/tension, and lateral loads of large structures.

The four main types of caisson are box caisson, open caisson, pneumatic caisson and monolithic caisson. Pier is typically dug out and cast in place using forms. * 2003 , (Bill Bryson), A Short History of Nearly Everything , BCA, p. 213: Caissons were enclosed dry chambers built on river beds to facilitate the construction of bridge piers. This main difference, which affects the overall behaviour and design of the foundation under both static (essentially vertical) and seismic loads, stems from the different length-to-width ratio (i.e. A Caisson is a watertight structure used for retaining water in order to work on the foundations for bridges, piers, and other structures. Pier foundations are required to resist the small load. A pile is a type of deep foundation which usually extends to a To choose between these three types of deep foundations a foundation engineer must know the differences between them. Caissons are driven into surface condition. See a new quieter and more concise version of this video at: http://www.youtube.com/watch?v=1LjRhB6uomA (rev Aug. 19, 2011 by JJ). Caisson-piles may consist of multiple circular rein-forcement bar layers, hence increasing load trans-fer capacity while maintaining a slender shape. Usually a double air lock door is used at the top of the caisson and the caisson is pressurized. The Inspection and cleaning at the bottom of the Caisson are difficult. Caisson types 1. What is the difference between a Caisson and Pile. Pier has a footing. It also has to do with soil types (too hard means you cannot drive a pile through it). McGraw-Hill Dictionary of Architecture and Construction. The types of caissons are box, open, pneumatic, monolithic, floating, excavated etc. Equivalent-linear ground response analyses are preliminary performed to derive the mobilized soil stiffness and damping ratio. Steel Piles are also installed every 6-10’ to add to the strength of the caisson wall.
