  • Combined pile foundations.

What is pile foundation and its types?

A Pile foundation , a kind of deep foundation, can be defined as a slender column or long cylinder made of materials such as concrete or steel which are used to support the structure and transfer the load at desired depth either by end bearing or skin friction. Pile foundations are deep foundations.

What are the three types of piles?

There are a four main types of pile foundation, each with its own method of construction:
  • Driven piles.
  • Bored piles.
  • Driven and cast-in-situ piles.
  • Aggregate piles.

What is pile capacity?

Definition. The pile capacity refers to the maximum load that can be borne by a pile under load, to ensure that strength and stability of foundation soil and pile itself can be guaranteed and the deformation is within the allowable range.

What are different piling equipment and methods?

 1) Drop 2) Single acting steam or compressed air 3) Double acting steam or compressed air 4) Differential acting steam or compressed air 5) Diesel 6) Hydraulic –Impact and drivers 7) Vibratory drivers PILE HAMMERS…

What are the different types of well foundation?

Shapes of Well Foundations:
  • Circular.
  • Twin circular.
  • Square/Rectangular.
  • Double D.
  • Hexagonal/Octagonal.

What is piling in construction?

Piling works by inserting large amounts of wood, steel or concrete into the soil of the ground. The deep insertion of these elements ensures a sturdier base for the construction project to take place.

What are the types of deep foundation?

The 5 Types of Deep Foundations
  • Basements.
  • Buoyancy rafts.
  • Caissons.
  • Shaft foundations.
  • Pile foundations.

What is the difference between pile and well foundation?

Well Foundation is the type of deep foundation which is mainly equipped below the water level for bridges. A Pile Foundation is one type of slender structural member made of steel, concrete, wood, or composite material.

Why are caissons used?

In geotechnical engineering, a caisson (/ˈkeɪsən/ or /ˈkeɪsɒn/; borrowed from French caisson, from Italian cassone, meaning large box, an augmentative of cassa) is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair

Where is well foundation used?

Well foundation is usually adopted for structures across rivers or streams, where heavy scouring is involved, such as for supporting the piers below the water level of a road or a railway bridge, or a barrage or an aqueduct, or some monumental building.

Why pile foundation is preferred?

Use of pile foundation

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.

What is pier and pile?

Piles foundations are typically found in coastal areas and are used when there is a layer of weak soil at the surface. Supports are driven into the ground and embedded several feet below grade. Post and pier construction uses a series of posts installed under the home which are mounted to concrete piers.

What is end bearing pile foundation?

End bearing piles (also known as point-bearing piles) are used to distribute large foundational loads from the topsoil, which has a low bearing capacity, to the rock beneath, which has a much higher bearing capacity. Loads can also be transferred to strong stratum such as dense sand and gravel instead of rock.

What is the function of pile?

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. Piles transfer the loads from structures to hard strata, rocks, or soil with high bearing capacity.

What is pile load test?

The static pile load test gives the most accurate indication of the capacity of the in-place pile. It is performed using a reaction method. The test procedure involves applying an axial load to the top of the test pile with one or more hydraulic jacks.

Which soil is suitable for pile foundation?

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.

How is pile length calculated?

Required Rnfield resistance is 150/0.5= 300 kips. Pile length is estimated as 57.5 ft from Figure 1 at the depth where Rnfield is equal to 300 kips. For the contract documents, include an estimated pile length of 60 ft and required Rndr of 300 kips to finalize this length during construction in the field.

What is a structural pile?

A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.

What is the minimum depth of pile foundation?

Depth of deep foundation depend on applied load on structure If the load on foundation is 500KN, minimum depth is 3.5m to 4.5m, If the load on foundation is in the range of 2000KN to 3000KN, minimum depth for pile foundation is 6.0m to 20.0m with pile caps.

How is pile depth calculated?

General factors to be considered for determining depth of foundation are:
  1. Load applied from structure to the foundation.
  2. Bearing capacity of soil.
  3. Depth of water level below the ground surface.
  4. Types of soil and depth of layers in case of layered soil.
  5. Depth of adjacent foundation.
