Pile foundations are principally used to transfer the loads from superstructures, through weak, compressible strata or water onto stronger, more compact, less compressible and stiffer soil or rock at depth, increasing the effective size of a foundation and resisting horizontal loads.
Where is pile foundation required?
Pile foundation is needed in areas where the structures constructed are large & heavy and the soil underlying is weak. In areas where settlement issues are common due to soil liquefaction or water table issues, pile foundation is a better choice.
What is meant by pile foundation?
A pile foundation is defined as a series of columns constructed or inserted into the ground to transmit loads to a lower level of subsoil. A pile is a long cylinder made up of a strong material, such as concrete. Piles are pushed into the ground to act as a steady support for structures built on top of them.
What is pile foundation and types of piles?
A Pile Foundation is one type of slender structural member made of steel, concrete, wood, or composite material. A Piles may be cast-in-situ excavating a hole and filling it with concrete or precast concrete member which is driven into the soil. There are different Types of Pile Foundation used in construction.
In which type of soil pile foundation is used?
The types of soil that most often require piling are those with high clay or silt content since these are fine-grained soils. They tend to collapse more easily, or else cause more uplift when they freeze.
What is pile foundation PPT?
Pile foundation • Pile foundation is that type of deep foundation in which the loads are taken to a low level by means of vertical members which may be Timber Concrete steel. 6. Uses of Piles • The load of the super-structure is heavy and its distribution is uneven. • The top soil has poor bearing capacity.
Do I need pile foundations?
Piled Foundation: When the soil is unstable or incapable of bearing the load on its own, a piled foundation will create a much stronger support structure on which to extend your house. If the soil has much sand, clay or peat, this will be the most effective way of building out the foundation.
How are pile foundations installed?
The pile casing is typically driven into earth or the ground and filled with concrete and reinforcement to arrive at the cast-in-situ pile. The other method involves an auger that is hollow stemmed that drills into the ground. This auger is then pumped with a material such as concrete in order to build up the pile.
Why is piling needed?
Used mainly in the construction of commercial and industrial buildings, piling helps to provide support to new structures when the soil near the surface is simply too weak to support the load in question or when the structures are so massive that extra foundational support is needed regardless of local soil conditions.
What is pile in construction?
pile, in building construction, a postlike foundation member used from prehistoric times. In modern civil engineering, piles of timber, steel, or concrete are driven into the ground to support a structure; bridge piers may be supported on groups of large-diameter piles.
When should pile foundations be used?
Pile foundations are principally used to transfer the loads from superstructures, through weak, compressible strata or water onto stronger, more compact, less compressible and stiffer soil or rock at depth, increasing the effective size of a foundation and resisting horizontal loads.
