Abstract: To repair a pair of adjacent corroded sheet pile coffer dam cells a vertical metal plate is welded to the joint between the adjacent arches of sheet piling in alignment with the diaphragm between the cells which is also connected to the joint. A precast, post-tensional concrete arch of approximately the same length and depth as the sheet pile arch is spaced outwardly of each sheet pile arch. Exposed reinforcing bars of the concrete arch are secured to an extension of the metal plate. An outer vertical plate bridges the gap between the outer corners of adjacent concrete arches. The space inside the outer plate and the arch joint is filled with grout (e.g., Tremied concrete or pressure grout). The spaces between the new concrete arches and the pre-existing sheet pile arches are also filled. The lateral forces from the fill behind the concrete arches are resisted by tension of the existing diaphragm between cells. Use of "deadmen" and other anchoring devices is obviated.
