    Vibro Hammer (Pile Driver) Vibro hammer is a kind of hydraulic attachment used to drive piles (poles) into soil to provide foundation support for buildings or other structures. Low maintenance costs are possible compared to cranes. Superior mobility is available for narrow spaces. Using excavator oil, it requires no extra power source.

    PILE DRIVING The operation of inserting a pile into the ground is known as pile driving. Piles are commonly driven by means of a hammer supported by a crane or a special device known as a Pile Driver. The various methods of pile driving are: 1. Hammer driving 2. Vibratory pile driver 3. Water jetting & hammering 4.

  • The Influence of Pile

    The ground vibration induced by pile driving affects the safety of the adjacent foundation pit. In this paper, the influence of pile-driving vibration on the soil strength and the nail-soil interface strength was studied, and the variation in the axial force and displacement of the soil nail under vibration was analyzed. The paper studied the effects under different vibration parameters on the

    4. Self formation of a pile A horizontal rigid plate vibrates vertically at a frequency of the order of 100 Hz. A cone-shaped pile of fine dispersed powder (e.g. lycopod or talc) which is heaped up on the plate remains stable at small amplitudes of the vibration. If the amplitude is increased the cone decays.
