Pile foundation | Classification of Piles

A pile foundation, categorized as a deep basis, broadly speaking ambitions to transfer the burden of a building or structure deeper into the floor. Notably, engineers commonly opt for pile foundations whilst the surface soil exhibits suggested weak spot or instability, rendering it improper for helping the shape’s weight.

To obtain this, engineers actively insert piles, which consist of long, slender columns made from substances like concrete, metallic, or wooden, into the floor. They employ various methods, including driving, drilling, or jacking. Furthermore, engineers typically install these piles in groups. This approach serves a dual cause: it complements load-sporting ability and ensures a good distribution of the structure’s load throughout the muse. Essentially, pile foundations offer a robust solution for successfully addressing hard soil conditions.

Here is Detail Discus on What is Pile foundation| Classification of Piles,

 Pile foundation Classification

Pile foundations may be labeled based totally on different criteria. The most common types of pile foundation classification are:

  • Classification based on function
  • Classification based on material
  • Classification based on method of installation

Classification based on function

(a). End-bearing piles

(b). Friction piles

(c). Combined cease-bearing and friction piles

End-bearing piles

They design these to transfer the load of the structure to a hard stratum or rock layer beneath the soil.

Friction piles

They layout these to transfer the load of the shape to the soil thru the frictional resistance between the pile and the encompassing soil.

Combined cease-bearing and friction piles

They design these to transfer the load of the structure to both the hard stratum and the surrounding soil.

Classification based on material

(a). Concrete piles

(b). Steel piles

(c). Timber piles

(d). Composite piles

(e). FRP piles

(f). Sheet piles

Concrete piles

These are made from strengthened or pre-burdened concrete and are broadly utilized in production.

Steel piles

These are fabricated from metal and can be both hole or stable. Steel piles are durable, smooth to put in, and may be used in various soil situations.

Timber piles

Builders make these from wood and commonly use them for temporary structures or smaller projects.

Composite piles

These are product of a mixture of materials such as metallic, concrete, or wood. Composite piles offer the benefits of various substances inclusive of durability, strength, and corrosion resistance.

FRP piles

These are unique poles made of a fabric referred to as Fiber Reinforced Polymer (FRP). People use them in locations in which there may be a lot of rust or chemical substances. FRP poles don’t without problems get damaged by way of rust, they may be light, and they’re sturdy for their weight.

Sheet piles

Engineers construct these from materials such as steel, vinyl, or wood, and they use them for retaining structures or providing lateral support. They drive sheet piles vertically into the ground and create a barrier by interlocking them with each other.

Pile foundation Classification based on method of installation

There are several types of pile foundations based on method

(A) Driven Piles

(B) Cast-In-Place Piles

(C) Auger Cast Piles

(D) Micro piles

(E) Helical Piles

Driven Piles

The most not unusual kind of pile basis is normally product of steel or concrete. Engineers install them with the aid of using the pile into the soil with a pile hammer, which transfers the burden from the pile to the soil.

Cast-In-Place Piles

Engineers create those piles by using drilling a hollow into the ground and then filling it with concrete. They improve the pile by means of placing steel inside the hollow earlier than pouring the concrete.

Auger Cast Piles

These piles are formed by drilling a hole into the soil and then injecting grout into the hole as the auger is removed. The grout hardens and forms the pile.

Micro piles

They’re no longer very extensive, generally much less than 12 inches throughout. Engineers placed them within the ground through drilling a hole and filling it with grout or concrete.

Helical Piles

These are screw-like piles that engineers screw into the soil with a machine. They typically employ them in regions with poor soil conditions or in situations where access is limited.
