초록 ▼

A clamp assembly for attaching a pile to a device for inserting and/or extracting the pile. The clamp assembly has a fixed gripping assembly and a movable gripping assembly. The fixed gripping assembly is rigidly attached to a housing. The movable gripping assembly is rotatably attached to a pivot arm that is pivotably attached to the housing. The pile is placed between the gripping assemblies and a piston causes the pivot arm to rotate such that the pile is gripped between the gripping assemblies. The movable gripping assembly rotates relative to the pivot arm into a desirable position relative to the pile as it engages the pile to increase the ability of the clamp assembly to grip the pile. An anvil formed on the top of the clamp assembly facilitates attachment of the clamp assembly to the pile driving and/or extracting device and alleviates damage to the bolts used to attach the clamp assembly to the pile driving and/or extracting device.

A system for driving caissons into the earth, the system comprising: means for supporting a lead structure above a desired location; sled means movable along the lead structure, the sled means having first and second support projections extending therefrom; a base plate, where a slot having an open end and a closed end is formed in the base plate; first and second vibrating means for generating vibratory forces, the first and second vibrating means being rigidly mounted to the base plate on opposite sides of the slot; first and second suppressing means connected between the first and second vibrating means and the first and second support projections, respectively, for inhibiting transmission of the vibratory forces generated by the first and second vibrating means to the first and second support projections; a first gripping assembly slideably mounted on the base plate adjacent to the closed end of the slot; a second gripping assembly; locking means for fixing the second gripping assembly in a closed position relative to the base plate in which the second gripping assembly closes the open end of the slot; and actuating means for displacing the first gripping assembly relative to the base plate between a relaxed position and a gripping position; wherein the caisson is arranged within and removed from the slot when the first gripping assembly is in the relaxed position and the second gripping assembly is not in the closed position; and the caisson is fixed to the attachment point when the first gripping assembly is in the gripping position and the second gripping assembly is in the closed position. A method of driving into the earth at a desired location a caisson prepositioned above the desired location, the method comprising the steps of: providing a driving device comprising (i) a base plate having a slot formed therein, (ii) a vibratory assembly rigidly mounted on the base plate, and (iii) a suppressor assembly rigidly connected to the vibratory assembly; rigidly attaching the suppressor assembly to a sled movably mounted on a lead structure such that the suppressor assembly inhibits transmission of vibratory forces from the vibratory assembly to the lead structure; mounting a clamping jaw to the base plate adjacent to a closed end of the slot therein; displacing the lead such that the caisson enters the slot in the base plate in a first direction generally radial to a lengthwise axis of the caisson; rigidly attaching a gate jaw in a closed position relative to the base plate such that the gate jaw prevents removal of the caisson from the slot in the base plate in a second direction opposite to the first direction; gripping the caisson between the clamping jaw and the gate jaw by displacing the clamping jaw towards the caisson; operating the vibratory assembly while gripping the caisson to apply a vibratory force to the caisson, thereby driving the caisson into the earth.
