Abstract
An apparatus and method for continuously preloading during installation and removal of steel sheet piles, steel pilings, and casing piles, comprising a telescoping, articulated boom having a free end for creating the downward driving force, a weighted base to provide support and stability for the boom, a connector at the free end of said boom to engage the piling, a modified resonance-free vibratory hammer, and a means for simultaneously vibrating the piling while applying to said piling the continuous downward or upward force.
Claims16
A method of driving a sheet piling that allows continuous force for preloading or extraction of the piling during installation comprising the steps of:
- providing an elongated bi-directional, hydraulic telescoping boom that creates a controlled downward or upward vertical force, said boom comprising:
- a telescopic portion, including a plurality of hydraulic double-acting cylinders for raising the boom from a horizontal to a vertical orientation and an internal hydraulic cylinder for extending and retracting a telescopic segment from a receptacle segment to accommodate different lengths of sheet piling;
- a middle portion, including a hydraulic double-acting cylinder, to provide control over the positioning of the vibratory hammer and to provide additional reach to the boom when it is being operated in its vertical orientation;
- and
- a free hinged end, including a hydraulic double-acting cylinder to create the downward or upward force to drive sheet piles;
- providing a large weighted base carrier that vertically supports the boom for counterbalancing a large downward or upward, hydraulically-harnessed force from the base carrier through said boom to said sheet piling;
- providing an articulated connector at the free end for connecting the boom to the sheet piling through a modified resonance-free vibratory hammer;
- connecting the aforementioned resonance-free vibratory hammer to the sheet piling to be installed or removed;
- applying a continuous downward or upward force from the boom on the sheet piling;
- and
- simultaneously vibrating said sheet piling to drive the sheet piling into soil under the sheet piling, or forcefully extracting said sheet piling from the ground.
A sheet pile driving machine providing continuous preloading of a sheet piling during installation or removal, comprising:
- an articulated boom having a free end for creating continuous downward force on the piling;
- a large weighted base vertically supporting the boom including a counterweight portion;
- a connector comprising a swivel engaged with a top panel of a vibratory hammer and a special universal joint engaged with the free hinged end of the boom for interconnecting said boom to the piling;
- a vibratory hammer engaged with the swivel of said connector;
- a plurality of connection pins for engaging said swivel with said universal joint and said universal joint with said free hinged end of the boom;
- a source of power for the base carrier and for the vibratory hammer;
- and
- means for vibrating the piling simultaneously with the creation of continuous downward or upward force.
