Understanding the Piling Methods of Hydraulic Pile Hammers

For those unfamiliar with the piling methods of pile hammers, let's explore the specifics as explained by a pile hammer manufacturer.

1. Hydraulic pile hammers are highly efficient in piling due to their high efficiency, low vibration, and lack of oil smoke pollution. These advanced features have led to the widespread acceptance of hydraulic pile hammers, which have completely replaced diesel pile hammers and become the dominant force in the piling market.

Based on their working principles, pile hammers can be divided into the following two types:

Single-Acting Hydraulic Pile Hammers:

2. Mechanism: The hydraulic oil is used to lift the pile hammer to a certain height. It is then quickly released, allowing the hammer to fall freely and impact the pile head, driving the pile into the ground.

Theory: This method follows the "heavy hammer, light blow" theory. The hammer itself is relatively heavy and falls slowly, resulting in a longer impact time and greater penetration per blow.

Applications: It is widely applicable, especially for concrete pipe piles, as it causes minimal damage to the pile body.

Double-Acting Hydraulic Pile Hammers:

Mechanism: The hydraulic oil is used to lift the pile hammer to a certain height. The hydraulic system then provides additional thrust to accelerate the hammer's fall, delivering a faster blow to the pile head.

Theory: This method follows the "light hammer, heavy blow" theory. The hammer itself is relatively light, but the impact force is increased by the additional thrust from the hydraulic system.

Applications: The impact force includes both the hammer's weight and the hydraulic system's thrust, making it effective for various piling tasks.

In summary, hydraulic pile hammers have become the preferred choice for piling due to their efficiency and reduced environmental impact. Whether using the single-acting or double-acting method, understanding these mechanisms helps in choosing the right equipment for specific piling needs.
