Abstract
Abstract A method for driving tubular piling into ground beneath water in which the end of the piling is sealed against the ground and a vacuum is applied in the upper end of the piling to draw the piling downward and to draw a portion of the ground into the piling. Thereafter, the piston effect may be used to adjust the level of the piling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
93 words
A method for driving tubular piling into ground beneath overlying water comprising a. providing a piston in said piling; b. sealing one end of said piling against the underlying ground; c. filling with water the lower chamber of the piling between said piston and the ground; d. closing the upper chamber in the interior of said piling immediately above said piston and e. evacuating the closed upper chamber to draw said piling downwardly with respect to said piston and the ground and to draw a portion of the ground into said lower chamber.
Claim 2
Independent Claim
93 words
A method for driving tubular piling into ground beneath overlying water comprising a. providing a piston in said piling; b. sealing one end of said piling against the underlying ground; c. filling with water the lower chamber of the piling between said piston and the ground; d. closing the upper chamber in the interior of said piling immediately above said piston and e. evacuating the closed upper chamber to draw said piling downwardly with respect to said piston and the ground and to draw a portion of the ground into said lower chamber.
Claim 3
Dependent Claim
25 words
The method of claim 1 including the step of hydraulically agitating the ground opposite the piston after the piling has been sealed against the ground.
Claim 4
Dependent Claim
19 words
The method of claim 2 including the step of subsequently removing matter from the lower chamber below the piston.
Claim 5
Dependent Claim
35 words
The method of claim 1 including the step of introducing a particulate solid into the lower region of said piling and thereafter compacting said particulate solids by applying pressure in the piling above the solids.
Claim 6
Dependent Claim
26 words
The method of claim 4 including the step of applying pressure to the upper region of the piling to raise the piling to a desired level.
Claim 7
Independent Claim
100 words
An apparatus for driving tubular piling including; a. a piston mounted for reciprocating on said piling and dividing said piling longitudinally into two chambers; b. means for filling a First of said chambers with water, said filling means including a pipe extending longitudinally in said piling; and c. means for closing and evacuating the second of said chambers, said closing and evacuating means including a head on said piling; d. said piston having an aperture for receiving said pipe slidably therethrough, said head having a first aperture communicating with said pipe and a second aperture communicating with said second chamber.
Claim 8
Independent Claim
100 words
An apparatus for driving tubular piling including; a. a piston mounted for reciprocating on said piling and dividing said piling longitudinally into two chambers; b. means for filling a First of said chambers with water, said filling means including a pipe extending longitudinally in said piling; and c. means for closing and evacuating the second of said chambers, said closing and evacuating means including a head on said piling; d. said piston having an aperture for receiving said pipe slidably therethrough, said head having a first aperture communicating with said pipe and a second aperture communicating with said second chamber.
Claim 9
Dependent Claim
15 words
Apparatus according to claim 6 in which the head is detachably mounted on said piling.
Claim 10
Dependent Claim
16 words
Apparatus according to claim 7 including a collar slideably mounted on the exterior of said piling.
