metal sheet pile
Sheet pile wall abutments are constructed from hot-rolled structural shapes with interlocks on the flange tips. These interlocks permit individual sections to be connected to form a continuous steel wall. Steel sheet piles are characterized by their profile which includes Z-profiles, U-profiles, and straight-profiles. The majority of design involved in using a sheet pile wall abutment comes in determining what type of sheet, vertical and horizontal forces are taken by the sheet piling in this structure, how deep to drive it and determine if and where anchorage devices are needed.
Sheet pile walls are used as a bridge abutment alternative. This system supports the soil adjacent to the bridge approach
