Abstract
Abstract In order to apply reinforced concrete to a portion of a steel pile, a reinforcing cage is attached to the pile surrounding that portion and is enclosed by a two-piece cylindrical form pulled tightly upwardly against the undersurface of the pile cap and having its lower end closed by a bottom plate. Concrete is pumped upwardly through the bottom plate to displace the water within the form.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
In a process for applying a reinforced concrete casing to an underwater steel supporting pile, the steps of positioning a reinforcing cage around that portion of the pile which is to be coated with concrete, positioning a bottom plate having an opening therethrough closely conforming to the configuration of the pile beneath said cage, placing a cylindrical-like form, with openings in its upper portion, around said cage and on said bottom plate, elevating said bottom plate and cylindrical-like form from the bottom to bring the upper end of said form into contact with the lower face of the pile cap to close the upper end thereof, and pumping concrete upwardly through the bottom plate into the cylindrical form, forcing the water within the form outwardly thereof through said openings until the form is filled with concrete.

Claim 3
Dependent Claim
23 words
A process as claimed in claim 1 wherein said reinforcing cage is in two parts with said parts bEing assembled around the pile.
Claim 4
Dependent Claim
24 words
A process as claimed in claim 1 wherein said cylindrical-like form comprises two parts with said parts being assembled around the pile and cage.
Claim 5
Dependent Claim
21 words
A process as claimed in claim 3 including the step of sealingly connecting the cooperating edges of the cylindrical-like form parts.
Claim 6
Dependent Claim
32 words
A process as claimed in claim 4 including the step of maintaining the cylindrical-like form tightly against the pile cap while the concrete is being pumped into the form and being cured.
Claim 7
Dependent Claim
28 words
A process as claimed in claim 1 including the steps of suspending the bottom plate around the pile and positioning the cylindrical-like form on the suspended bottom plate.
Claim 8
Dependent Claim
39 words
A process as claimed in claim 1 including the steps of clamping the form before pouring of the concrete therein, removing the clamps after the concrete therein is cured, the form remaining in position so as to eventually deteriorate.
