摘要：A vibratory pile driver configured to insert curved sheet pile beneath a conduitby rotating the pile driver about a fixed pivot element to advance the curved sheet pile
along a fixed arc. In one exemplary embodiment, the distance between the fixed pivotelement and the clamps that secured the curved sheet pile to the pile driver is the sameas the radius of curvature of the curved sheet pile. In another exemplary embodiment,when the curved sheet pile is secured to the pile driver by the clamps, the center of theradius of curvature of the curved sheet pile lies substantially on the rotational axis of thefixed pivot element. In this embodiment, the vibratory pile driver may be rotated aboutthe fixed pivot element to advance the curved sheet pile along an arc having curvaturesubstantially identical to the radius of curvature of the curved sheet pile.
