Construction Technology Of Hydraulic Impact Pile Hammer
The Hydraulic Impact Hammer features good controllability, a wide range of adaptability, high impact efficiency, low pollution, and low noise. Precast piles are increasingly used in pile foundation construction. Environmental regulations are constantly being refined, and large-scale projects, particularly marine technologies (such as offshore wind power, offshore oil projects, cross-sea bridges, and deep-water docks), are driving the development of larger and deeper precast piles. These factors have created favorable conditions for the application of the Hydraulic Impact Hammer. In different projects and environments, combining theory with construction experience, selecting the appropriate Hydraulic Impact Hammer model will greatly improve construction efficiency.
Based on the structure and operating principle of the Hydraulic Impact Hammer, the Hydraulic Impact Hammer can be divided into two categories: single-acting and double-acting. The single-acting Hydraulic Impact Hammer uses hydraulic oil to raise the hammer core to a certain height, then quickly releases it, causing the hammer core to impact the pile top through free fall. The double-acting Hydraulic Impact Hammer uses hydraulic oil to raise the hammer to a certain height. The hydraulic system then controls the hydraulic oil, which changes direction, propelling the Hydraulic Impact Hammer to impact the pile top with greater kinetic energy. The impact at this time can not only provide the gravity energy of the impact hammer, but also provide the energy provided by the powerful thrust of the pressure oil, so that the acceleration of the Hydraulic Impact Hammer falling exceeds the free fall acceleration p.
