  • Pile repair apparatus
    Patent number: 10246845
    Abstract: A pile repair apparatus includes a metal clamp having left and right brackets connected by a hinge member. A friction surface is positioned along an inner surface of the metal clamp to improve the connection of the apparatus to a pile to be repaired. A platform is connected to a top surface of the metal clamp, and a means for providing buoyancy to the pile repair apparatus can be secured to the platform. The buoyancy of the apparatus allows a diver to move and to submerse the apparatus easily and to position the apparatus around a pile to be repaired by opening and closing the apparatus about the hinge member. The apparatus is secured to the pile by inserting a bolt through corresponding apertures in the left and right brackets of the apparatus.
