What Is a Pile Driver and How Does It Work?

A pile-driving machine (also known as a pile driver) is a machine that drives piles into the earth to form a foundation for buildings and other large structures.

What Are Pile Driving Machines and How Do They Work?

Traditional pile drivers and vibratory pile drivers are the two primary types of pile driving machinery.

Pile Drivers (Traditional)

Traditional pile driving machines work by releasing a weight atop a pile, sliding down vertically, and smashing the pile into the earth. Mechanically, the weight is increased, and it can be propelled by hydraulics, steam, or diesel. The weight is discharged when it reaches its highest position. Gravity pulls the weight down and places it on top of the pile. The pile is hammered into the soil by the weight of the pile. This step is repeated until the pile is completely embedded in the ground.

Vibratory Pile Drivers

Vibratory pile driving machines (also known as vibratory hammers) create a vibration by spinning counterweights, causing a pile to “cut” into the soil below. A vibratory hammer acts like an electric knife cutting through flesh, whereas a typical pile driver works like a hammer and a nail.

Pile Driving Machines Are Required

Not every construction project will necessitate the use of piles or pile driving devices. Foundation piling is only required if the soil can no longer support the weight of the structure being constructed. This could happen if the construction site has a soft layer of soil on the surface that can’t withstand the weight of a new structure.

Pile Drivers: What Are They and What Do They Do?

Hammer with a diesel engine

A diesel impact hammer (also known as a diesel pile hammer or a diesel pile driver) is a classic pile driver driven by a big two-stroke diesel engine.

Hammer Powered by Steam

A classic pile driver that is driven by compressed air or steam is known as a steam impact hammer.

Impact Hammer (hydraulic)

A hydraulic impact hammer is a third type of classic pile driver that is hydraulically propelled. Hydraulic impact hammers are thought to be less harmful to the environment than diesel impact hammers.

Vibratory Hammer

Unlike traditional pile drivers, which smash piles into the earth with a high weight, vibratory hammers employ vibrations to move heaps into the soil and recover old piles from the ground.

Noise Considerations

Noise pollution can be a concern with traditional pile driving devices that use a weight to force a pile into the earth. The impact of the hammer hitting the pile, or the collisions between the components of a hammer, produces the most noticeable noise from a pile driver, which can be disturbing to people and wildlife. Vibratory hammers, on the other hand, are quieter because they don’t use a hammer-weight mechanism.
