Analysis Of The Structural Data And Working Principle Of Hydraulic Impact Pile Driver

hydraulic impact hammer belongs to the category of impact pile hammers, which can be divided into single-acting hammers and double-acting hammers based on their structure and working principle. A single-acting hammer refers to the hammer core being rapidly released to a predetermined height via a hydraulic device, allowing it to fall freely. A double-acting hammer refers to the hammer core being raised to a predetermined height via a hydraulic device, accelerating energy from the hydraulic system to increase the impact speed and drive the pile. This also corresponds to two different pile theories. hydraulic impact hammer pile driver corresponds to the heavy hammer theory, characterized by a large hammer core weight, low impact speed, and long hammering time. Each impact penetrates deeply, making it suitable for various shapes and materials. The pile damage rate is low, making it ideal for concrete.

excavator impact hammer is a new type of hydraulic pile driver that can adjust the hydraulic pressure according to the soil quality to achieve appropriate impact force. Small and medium-sized hydraulic pile drivers are commonly used for road guardrail piling and construction. Similar pile driving equipment to hydraulic hammer pile driver includes: hydraulic pile drivers, road pile drivers, guardrail pile drivers, and road drilling machines. Compared to diesel pile drivers, hydraulic hammer pile drivers have an energy transfer efficiency of 70% to 95%, while diesel hammer pile drivers only have an energy transfer efficiency of 20% to 30%. The hydraulic impact pile hammer features precise pile driving control, enabling pile driving operations in different geological formations.
