Abstract
Abstract Top and bottom segments of marine piling are spliced and reinforced in situ by surrounding them with an elongated cage of concrete mesh rebar stock or like material, surrounding the cage with an elongated concrete form bag, spacing the cage from the piling and the form bag from the cage, and pouring the form bag full of concrete mix thereby integrating the piling segments, the cage and the form bag into a repaired or spliced pile of substantial strength. Where the splice extends below the mud line, the area about the pile first is excavated down into the underlying solid ground to provide a concrete form basin which also is filled with concrete to provide a footing for the spliced pile.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
151 words
Apparatus for splicing in situ top and bottom segments of marine piling, the bottom segment being embedded in the ground, the apparatus comprising in combination: a. an elongated cage of stiff, fluid-cement-permeable mesh material dimensioned to surround and overlap both of the pile segments while bridging the space between the segments, b. an elongated concrete form bag of longitudinally collapsible, substantially fluid-cement-impermeable material dimensioned to overlie the cage, c. a plurality of radially extending spacers dimensioned to abut the pile segments on one side of the cage and the concrete form bag on the other side of the cage, thereby spacing the cage predetermined radial distances to opposite sides of the pile segments and form bag, respectively, d. securing means securing the spacers to the cage, and e. fastening means fastening the top and bottom of the concrete form bag to the top and bottom segments of the marine piling, respectively.
Claim 2
Dependent Claim
151 words
Apparatus for splicing in situ top and bottom segments of marine piling, the bottom segment being embedded in the ground, the apparatus comprising in combination: a. an elongated cage of stiff, fluid-cement-permeable mesh material dimensioned to surround and overlap both of the pile segments while bridging the space between the segments, b. an elongated concrete form bag of longitudinally collapsible, substantially fluid-cement-impermeable material dimensioned to overlie the cage, c. a plurality of radially extending spacers dimensioned to abut the pile segments on one side of the cage and the concrete form bag on the other side of the cage, thereby spacing the cage predetermined radial distances to opposite sides of the pile segments and form bag, respectively, d. securing means securing the spacers to the cage, and e. fastening means fastening the top and bottom of the concrete form bag to the top and bottom segments of the marine piling, respectively.
Claim 3
Dependent Claim
33 words
The pile splicing apparatus of claim 1 wherein the pile segments are spaced from each other and including a post inserted in the space between the segments and bearing endwise against the same.
Claim 4
Dependent Claim
49 words
The pile splicing apparatus of claim 1 wherein each spacer comprises two separate abutment sections and the securing means comprises at least two prongs and cooperating recesses on the confronting surfaces of the abutment sections, the prongs being spaced apart laterally for receiving the cage mesh material between them.
Claim 5
Independent Claim
141 words
The method of splicing in situ top and bottom segments of deteriorated piling which comprises: a. mounting an elongated cage of stiff, fluid-cement-permeable mesh material about the piling, overlapping both of the pile segments, b. mounting an elongated concrete form bag of longitudinally collapsible, substantially fluid-cement-impermeable material about the cage, c. spacing the cage a predetermined radial distance outward from the piling and the concrete form bag a predetermined radial distance outward from the cage. d. securing the top and bottom of the concrete form bag to the top and bottom segments of the piling, respectively, e. filling the spaces between the cage and piling and concrete form bag and cage with unset, pourable cement mix and f. permitting the cement mix to harden, thereby forming an integrated spliced pile including the piling segments, the cage, and the concrete form bag.
Claim 6
Independent Claim
141 words
The method of splicing in situ top and bottom segments of deteriorated piling which comprises: a. mounting an elongated cage of stiff, fluid-cement-permeable mesh material about the piling, overlapping both of the pile segments, b. mounting an elongated concrete form bag of longitudinally collapsible, substantially fluid-cement-impermeable material about the cage, c. spacing the cage a predetermined radial distance outward from the piling and the concrete form bag a predetermined radial distance outward from the cage. d. securing the top and bottom of the concrete form bag to the top and bottom segments of the piling, respectively, e. filling the spaces between the cage and piling and concrete form bag and cage with unset, pourable cement mix and f. permitting the cement mix to harden, thereby forming an integrated spliced pile including the piling segments, the cage, and the concrete form bag.
Claim 7
Dependent Claim
40 words
The method of claim 4 including the step of cutting away a deteriorated central section of the piling and inserting a support post between the residual top and bottom segments thereof preliminary to placing the cage and concrete form bag.
Claim 8
Dependent Claim
54 words
The method of claim 4 including the step of longitudinally collapsing the concrete form bag and attaching its upper end to the top pile segment preliminary to placement of the cage about the piling, and thereafter spreading the form bag downwardly about the cage and fastening its lower end to the bottom pile segment.
Claim 9
Dependent Claim
80 words
The method of claim 4 including the step of digging a hole of predetermined depth and span about the bottom of the piling below the mud line, extending the concrete form bag into the hole and securing it to the piling, filling the hole with unset liquid cement mix, and thereafter filling the concrete form bag with unset liquid cement mix before the liquid concrete mix in the hole has set, thereby forming a concrete footing integrated with the pile.
Claim 10
Dependent Claim
28 words
The method of claim 4 including the step of introducing unset fluid cement mix spirally about the pile in the space between the cage and the form bag.
Claim 11
Dependent Claim
46 words
The method of claim 4 including the initial steps of cutting away a deteriorated central section of the piling, longitudinally collapsing the concrete form bag and inserting it upwardly over the top piling segment, and inserting a support post between the top and bottom piling segments.
Claim 12
Dependent Claim
135 words
Apparatus for splicing in situ top and bottom vertically aligned segments of marine piling and comprising in combination: a. a wire mesh cage dimensioned to surround and overlap both of the pile segments a spaced distance radially therefrom, b. a substantially water-impervious-concrete form bag dimensioned to overlie the cage and c. a plurality of radially extending spacers supported on the cage and dimensioned to space the cage a predetermined distance outward from the pile segments and the form bag a predetermined distance outward from the cage, d. each spacer comprising 1. two abutment sections one disposed on each side of the cage and 2. prong and recess interconnecting means on the adjacent faces of the abutment sections arranged for mutual interengagement of the sections with each other and with the wire mesh of the cage.
