Abstract
A one-step sheet pile retaining wall system for embankment widening typically associated with highway widening not requiring temporary shoring. The wall system may provide a front wall face having a plurality of resistance fins perpendicularly extending therefrom. The fin sheet piles first include a brace fin sheet for reducing stresses in the front wall face, then a series of cradle fin sheets terminating at an elevation below the brace fin sheet for accommodating a pipe drainage/utility cradle, and finally a series of predominantly resistance fin sheets terminating at an elevation above the cradle fin sheets. Between the slope of the existing embankment and the higher front wall face may be cementitious flowable backfill for pre-stressing the wall system when fluid and, when set, supporting the aforementioned cradle, from which the remaining construction can build off of while reducing overall earth pressure acting on the wall face upon completion of construction.
