The construction form of an excavator pile driver determines whether the equipment itself or the surrounding environment will experience significant or minor vibrations during the construction process. The vibration of the excavator pile driver originates from the operation of the mechanical control system and external forces, while the vibration of the external environment results from mechanical construction.

The vibration force of the excavator pile driver, which is the system's high-frequency vibration, vibrates the pile body with high acceleration and transmits the vertical vibration generated by the machine to the pile body. This causes the soil structure around the pile to change due to the vibration, reducing its strength. The soil around the pile becomes more fluid-like, reducing the friction resistance between the pile side and the soil. The pile is then driven into the soil using the excavator's downward pressure, the vibratory pile driver, the pile extraction hammer, and the pile's own weight.

Vibratory work is a highly efficient method for pile driving, but excessive vibration force can impact the equipment itself and the surrounding environment, causing unnecessary damage. Therefore, implementing vibration reduction measures while ensuring construction effectiveness is a key consideration for construction companies using excavator pile drivers.

In general, using spring damping is less effective, as it results in significant energy loss transmitted along the wire rope, accounting for about 15%-25% of the total vibration energy. This may also damage auxiliary lifting equipment. In the equipment's damping design, damping rubber parts driven by a hydraulic motor are used to generate high-speed rotation and vertical vibration force. After passing through the damping rubber blocks, a certain amplitude is maintained to meet the requirements of various soil types and pile driving operations.

Integrated Gear/Eccentric Block:

Redundant fasteners in the gearbox.

Dual-Stage Damping Block System:

Dual pull-up force.

Adjustable Damping Box:

Adjusts height and weight according to project requirements.

Oblique Eccentric Gear:

Ensures smoother transmission.

More effective environmental damping requires a thorough investigation of the conditions of adjacent buildings or structures and underground pipelines. Appropriate isolation and damping measures should be studied and implemented to prevent damage to existing buildings or structures and accidents involving underground pipelines. For high-risk buildings that cannot be reinforced, demolition may be considered with appropriate approvals to ensure the safety of the construction site, neighboring buildings, and personnel.
