A reciprocating hammer with a two-stage acceleration of a pile driving ram, including a first stage in which initial gravitational acceleration is assisted by a thruster and a second stage in which the initially accelerated ram is allowed to further accelerate under the force of gravity alone for the remainder of the pile driver stroke. The force assist in the initial acceleration stage acts as a force multiplier, such that the anvil delivers impact forces to the pile greater than the impact forces achievable by gravity alone for a given stroke length/ram weight combination.

A pile is disclosed for insertion by a pile driver. The pile incorporates transversely extending anchors for increased pull-out resistance.

Pull-out resistant piles

Apparatuses, systems and methods are utilized to relocate subsurface conduit. Specifically, the movement of underground conduit is accomplished via the apparatuses, systems and methods described herein, including movement thereof in either or both of laterally from a first lateral position to a second lateral position and/or vertically from a first vertical position to a second vertical position.

Apparatus, systems and methods for the relocation of subsurface conduit

A vibratory pile driver configured to insert curved sheet pile beneath a conduit by 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 pivot element and the clamps that secured the curved sheet pile to the pile driver is the same as 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 the radius of curvature of the curved sheet pile lies substantially on the rotational axis of the fixed pivot element. In this embodiment, the vibratory pile driver may be rotated about the fixed pivot element to advance the curved sheet pile along an arc having curvature substantially identical to the radius of curvature of the curved sheet pile.

Method and apparatus for facilitating the subterranean support of underground conduits having a fixed insertion axis

The present invention relates to a support system for supporting a conduit. In one exemplary embodiment, the system includes support beams extending across an excavated opening. For example, a pair of beams may be positioned to span the excavated opening with the opposing ends of the beams supported on the ground above the excavated opening. Support rods may be positioned to extend through and/or from the beams and into the excavated opening. In one exemplary embodiment, the support rods include a J-hook configured for receipt within an opening in sections of curved sheet pile positioned beneath a conduit. By using a plurality of rods, the individual sections of curved sheet pile may be connected to the beams to provide a support structure for the curved sheet pile and, correspondingly, the conduit extending above the curved sheet pile and below the beam.

Systems for the subterranean support of underground conduits

An apparatus and method for the subterranean support of underground conduits is disclosed, including a pile driver that is configured to connect to an articulated boom of an excavator or another unit of positioning machinery to insert a section of curved sheet pile beneath a conduit. In one exemplary embodiment, the pile driver has a head portion and a body portion. The head portion of the pile driver is connected to the excavator and the body portion of the pile driver is moveable relative to both the head portion of the pile driver and the excavator to allow the pile driver to properly orient a section of curved sheet pile for insertion into subterranean material beneath an underground conduit.

Apparatus for inserting sheet pile having an independently adjustable insertion axis and method for using the same

In one exemplary embodiment, curved sheet pile is driven underneath an existing conduit using a pile driver guided hydraulically by an excavator or other heavy machinery. By vibrating the curved sheet piles, the soil is placed in suspension, which allows the piles to be directed through the soil along an arcuate path that has a curvature that substantially matches the radius of curvature of the piles. Once the pile is positioned as desired, each individual pile sheet can be welded to one another to form a unitary structure. In one exemplary embodiment, the curved sheet pile is inserted beneath a conduit using a vibratory pile driver that rotates about a fixed pivot element on an excavator or other heavy machine for positioning the pile driver to advance the curved sheet pile along a fixed arc.

Method and installation for the subterranean support of underground conduits

In one exemplary embodiment, the present invention includes a plurality of individual curved sheet piles that are positioned beneath an underground conduit, such as a raceway, to support the conduit during excavation. In one exemplary embodiment, the individual sections of curved sheet pile are interfit and/or interconnected. This allows the individual sections to work in combination with one another to support the conduit. Specifically, opposing ends of a length of interfit and/or interconnected curved sheet piles extend into unexcavated soil on both sides of an excavated hole to form a bridge across the hole that supports the conduit and any soil or other subterranean material positioned above the curved sheet pile.

Methods for the subterranean support of underground conduits

A pile driver including an apparatus for allowing relative movement between a hammer and a boom of an excavator. The apparatus includes a mounting plate mounted to the boom that interfits with and is slidable with respect to a frame rail mounted to the hammer. In operation, the hammer is placed on top of a pile and, as the pile is driven downwardly, the hammer follows the pile. Owing to the relative movement between the boom of the excavator and the hammer, the hammer follows the pile without requiring continuous downward readjustment of the boom. In one embodiment, the mounting plate assembly does not extend substantially above the hammer frame. In another embodiment, the hammer can rotate with respect to the boom. In one embodiment, the hammer includes a ram, a cylinder for lifting the ram, and rotation-resistant cable connecting the ram and the cylinder.

Pile driver

An apparatus for impacting on a hard surface such as concrete so as to break up the hard surface. This apparatus comprises a frame having a bed and an upstanding rail assembly projecting from the bed, a drive shoe, a hammer means attached to the rail assembly so as to be movable in only one direction and operatively connected to the drive shoe for impacting upon the drive shoe. The drive shoe lies adjacent the surface so that upon impact from the hammer means, the shoe forcefully impacts the surface so as to break up the surface. An adjustment means is used to selectively position the drive shoe relative to the hammer means.
