Abstract
A sheet pile retaining wall system employing corrugated sheet piles not requiring temporary shoring to be used when widening and/or stabilization of existing highway embankment. The wall system provides a front face wall having a plurality of resistance fins perpendicularly extending therefrom via three-way connectors. The fin sheet piles first include a brace fin sheet for reducing stresses in the front face wall, then a series of additional resistance fin sheets terminating at an elevation below the face wall for accommodating a pipe drainage/utility cradle. Between the slope of the existing embankment, a temporary excavation bench, an excavation backslope, and the higher front face wall is reinforced concrete backfill for pre-stressing the wall system when fluid—and, when set, optionally engaging supplementary structural features within the set concrete backfill such as dowels/tie down anchors.
