A two-part pile splice forming a pile protector and reinforcer and a method for reinforcing a deteriorated wood pile under a bridge wherein a first pile-protector and reinforcer-member having a flange is positioned on one side of a deteriorated wood pile with the flange located parallel to the flow of water under the bridge, and a second pile-protector and reinforcer-member with opposite flange is positioned on the opposite side of the wood pile with the flanges of the second pile protector and reinforcer spaced from and parallel to flow of water under the bridge. The pile protector and reinforcers are squeezed around the pilings to form a mechanical link thereto but not crash the wood piles and an epoxy which provides the compressive strength for the wood pile is filled into those areas in which the wood pile has voids.

A method for repairing bridge supports with a pile splice comprising the steps of: removing a section of decayed wood from a portion of a wood pile supporting a bridge to leave a top undecayed region and a bottom undecayed region of the wood pile in substantially cylindrical shape and an intermediate region with a substantial portion of the wood pile removed; fastening a first rigid semi-cylindrical pile-protector and reinforcer-member having a flange with a plurality of openings therein and an interior surface to a first side of the wood pile, with a first end of the first semi-cylindrical pile protector and reinforcer extending onto a first side of the top undecayed region of the wood pile and the a second end of the first semi-cylindrical pile protector and reinforcer extending onto a first side of the bottom undecayed region of the wood pile; fastening a second semi-cylindrical pile-protector and reinforcer-member having a flange with a plurality of openings therein and an interior surface to a second side of the wood pile, with a first end of the first semi-cylindrical pile protector and reinforcer extending onto a second side of the top undecayed region of the wood pile and a second end of the first semi-cylindrical flange extending onto a second side of the bottom undecayed region of the wood pile, with the flanges of the first semi-cylindrical pile protector and reinforcer and the second semi-cylindrical pile protector and reinforcer oppositely disposed and spaced from one another; squeezing a first portion of the first semi-cylindrical pile-protector and reinforcer-member and the second semi-cylindrical flanged pile-protector and reinforcer-member around the wood pile through a plurality of compression members extending through the flanges until a top end of the first semi-cylindrical flanged pile-protector and reinforcer-member and a top end of the second semi-cylindrical flanged pile-protector and reinforcer-member firmly engage but do not crush the top undecayed region of wood in the wood pile and squeezing a second portion of the first semi-cylindrical protector and reinforcer-member and the second semi-cylindrical flanged pile-protector and reinforcer-member around the wood pile through a plurality of further compression members extending through the flanges until a bottom end of the first semi-cylindrical flanged pile-protector and reinforcer-member and a bottom end of the second semi-cylindrical flanged pile-protector and reinforcer-member firmly engage but do not crush the bottom region of undecayed wood in the wood pile to thereby simultaneously form a mechanical link around the undecayed top and bottom portions of the wood pile to resist flexing and torsional forces on the wood pile and a cavity between the wood pile and the pile-protector and reinforcer-members; injecting an epoxy filler under sufficient pressure through an opening in the first semi-cylindrical pile-protector and reinforcer-member and into the cavity to thereby fall the cavity with epoxy to form a plug to support the wood pile during a compression loading of the wood pile so that the wood pile is strengthen from torsional and flexing forces by the reinforcer-members and from compression by the plug.
