The invention relates to a plastic jacket that is used for repairing underwater piles that have been corroded by the wave action at the waterline or by a tidal zone. The jacket consists of a cylindrical wall having annular corrugations on its exterior surface. The cylindrical wall has a longitudinal cut along its length to exhibit two opposing edges. A seal is placed between the opposing edges. Opposite from the longitudinal cut there is a V-shaped cut through the corrugations to the cylindrical wall to create a living hinge in the plastic material of the wall. Banding is provided to pull the opposing edges into a tight relationship and trapping the seal there between. The V-shaped cuts enable the jacket to be opened and placed around a damaged pile in spite of the corrugations which would prevent such an opening.
An underwater pile repair jacket form made of a plastic material comprising a solid wall cylinder having annular corrugations on its exterior surface, a longitudinal cut made through said solid wall and through said corrugations to thereby expose edges of said wall and said corrugations, a V-shaped cut made into said corrugations opposite from said longitudinal cut to said solid wall thereby creating a live hinge in said plastic material, a longitudinal seal placed on at least one edge of said edges, means for pulling said edges together and fastening said edges into a tight relationship.
A system for repairing an underwater pile having a corrosion area between the wave action of a body of water and a high and low tidal zone comprising a repair jacket form surrounding said pile, said repair jacket form consisting of a plastic cylindrical wall having annular corrugations on an exterior surface thereof and further having a longitudinal cut along its length to create opposing edges, a V-shaped cut placed through said annular corrugations onto said wall to thereby create a living hinge in said plastic cylindrical wall, a seal placed between said opposing edges, means for bringing said edges together into an intimate relationship with said seal trapped there between, means for closing a bottom of said jacket including a bag made of nylon material, means for fastening said bag of nylon between at least two of said corrugations and a circumference of said pile.
