In one embodiment, a pile splicing system and method uses a pile segment adapted to form part of a spliced pile, the pile segment including an elongated concrete body having first and second ends, one-way anchor embedded in the body that is adapted to resist passage of a post-tensioning strand in a direction toward the first end of the body; and a splicing duct embedded in the body that extends from the first end to the embedded one-way anchor.

In one embodiment, a system for applying reinforcement material to an existing structure includes a work rail adapted to be temporarily secured to a bottom surface of the structure, adhesive applying apparatus supported by the work rail, the adhesive applying apparatus being adapted to form an adhesive layer on the bottom surface of the structure adjacent the work rail, and reinforcement material applying apparatus supported by the work rail, the reinforcement material applying apparatus being adapted to apply reinforcement material to the adhesive layer formed on the bottom surface of the structure.

Provided is a method for enhancing an adhesive bond between a pile and a resin adhesive by maintaining a constant uniform positive pressure of the entire wrapped region regardless of the shrinkage in the resin adhesive. This invention enhances underwater adhesive bond by ensuring proper contact while curing. In one embodiment, constant inward pressure is created by encapsulating the repair and applying a vacuum. The invention can be used for a variety of underwater applications using different resins and different substrate materials. For instance, the invention could be used to repair damaged critical infrastructure, e.g. Bridges, dams, pipelines and locks. Local, state and federal agencies in US and elsewhere as well as marine and naval contractors would find great utility with the invention. The concept could be extended to all adhesion dependent repairs.
