A pile driver (also known as a pile driver) is used to drive piles into the ground to form the foundation that supports buildings and other large structures.
How a pile driver works
There are two main types of pile drivers: conventional pile drivers and vibratory pile drivers (careddi pile drivers product lists).
Conventional Pile Driver
A conventional pile driver works by using a weight placed over a pile that is released, slides vertically downward and strikes the pile, hammering it into the ground. The weight is mechanically lifted and can be driven by hydraulics, steam or diesel. When the weight reaches its highest point, it is released. Gravity causes the weight to drop, dropping it onto the pile. The impact of the weight on the pile hammers it into the soil. The process is repeated until the pile is completely driven into the ground.
Vibratory pile driver
Vibratory pile drivers (also called vibratory hammers) use a rotating counterweight to create vibrations that cause the pile to “cut” into the soil below. While a conventional pile driver works like a hammer and nail, a vibratory hammer works more like an electric knife that cuts through meat. The high speed vibration loosens the soil and makes it easy for the pile to slide into the ground.
The Need for Pile Drivers
Not all construction projects require pile driving or pile drivers. Foundations are only necessary when the soil cannot support the weight of the structure being built. This can happen if the construction site has a soft layer of soil on the surface to the extent that the soil cannot support the weight of the new structure. Likewise, if a particularly heavy building is being constructed, the surface soil will not be able to support its weight. In both cases, foundation piling can be used to transfer the weight of the structure from the surface of the soil to the stronger soil or rock below.
Types of pile drivers
Diesel Impact Hammer
A diesel impact hammer (also known as a diesel pile driver or diesel pile driver) is a traditional pile driver powered by a large two-stroke diesel engine.
Steam Impact Hammer
A steam impact hammer is a conventional pile driver powered by compressed air or steam.
Hydraulic Impact Hammer
The hydraulic impact hammer is the third type of conventional pile driver powered by a hydraulic system. Hydraulic impact hammers are considered to be more environmentally friendly than diesel hammers.
Vibratory Hammer
Unlike conventional pile drivers that use large weights to drive piles into the ground, vibratory hammers use vibration to slide the piles into the soil as well as to pull old piles out of the ground.
Noise Precautions
Conventional pile drivers that use heavy weights to drive piles into the ground can have noise pollution problems. The primary noise emitted by pile drivers is caused by the impact of the hammer hitting the pile or by collisions between hammer components, and can be disturbing to people and wildlife. Vibratory hammers, on the other hand, are relatively quiet because they do not use a hammer weight system.
