Abstract: A replacement bent for shoring a bridge and a method for installing the replacement bent. The replacement bent comprises a metal I-beam sill, telescoping, adjustable posts, and a metal I-beam cap. In one embodiment, the adjustable posts are connected at one end by hinges to the sill beam and are connected at the other end by hinges to the cap beam. In a second embodiment, the adjustable posts are connected at right angles to the cap beam and the sill beam by means of support plates. The posts may be telescoped and thereby adjusted to the necessary distance between the sill beam and the cap beam. The replacement bent is supported on the stub piles from the substandard bent that has been removed.

Abstract: A method and apparatus for replacing a bridge using pre-cast materials, including steel piles, steel reinforced concrete caps, and metallic male and female connectors. The pre-cast materials can be formed to precise standards in a controlled factory environment before being brought to the worksite for the bridge replacement project. Further, the male and female connectors provide for a quick and robust way to connect the caps to the piles without the use of welding between the piles and the caps.
