Abstract
Abstract A column member which may comprise a piling, casing, shaft or the like, is driven into the ground by means of sonic energy generated by a vibration generator. The vibration generator, which may comprise an orbiting mass oscillator, is coupled to the column member by a high impedance compliant element, the compliancce of this element and the mass of the column forming a resonant vibration system. The vibration generator is operated at a frequency such as to cause resonant vibration of the system with the compliant element providing lumped constant compliance and the column member providing lumped constant mass in such system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A device for driving A column member into the ground comprising: a vibration generator, a compliant member for coupling said vibration generator to said column member, said compliant member and said column member forming a resonant vibration system with most of the compliance of said system being provided by said compliant member and most of the mass of said system being provided by said column member, and means for driving said vibration generator at a frequency such as to cause resonant vibration of said system with said column member vibrating unitarily as a lumped mass and thereby penetrating into the ground.
Claim 2
Independent Claim
101 words
A device for driving A column member into the ground comprising: a vibration generator, a compliant member for coupling said vibration generator to said column member, said compliant member and said column member forming a resonant vibration system with most of the compliance of said system being provided by said compliant member and most of the mass of said system being provided by said column member, and means for driving said vibration generator at a frequency such as to cause resonant vibration of said system with said column member vibrating unitarily as a lumped mass and thereby penetrating into the ground.
Claim 3
Dependent Claim
41 words
The device of claim 1 wherein said compliant member comprises an elastic beam structure, said structure including paired plates, the ends of said plates being connected to each other and the central portions of said plates being separated from each other.
Claim 4
Dependent Claim
16 words
The device of claim 2 wherein said structure comprises two pairs of similar oppositely positioned plates.
Claim 5
Dependent Claim
13 words
The device of claim 1 wherein said compliant member comprises hydraulic spring means.
Claim 6
Dependent Claim
56 words
The device of claim 4 wherein said hydraulic spring means comprises a pair of hydraulic springs, each of said springs having a piston element connected to said vibration generator, a housing connected to said column member, and oil contained in said housing, said piston being slidably mounted in said housing in driving engagement with said oil.
Claim 7
Dependent Claim
44 words
The device of claim 1 wherein said compliant member comprises a pair of coil springs, housing means for supporting said springs, drive plate means positioned between said springs and said housing means, and means for coupling said drive plate means to said vibration generator.
