Tieback anchors shoulJ bc used for rcsisting lateral loads in the dircclion towards the stccp slope. Pin piles and helical anchors and their accessories should be ttated with asphahic paint or galvanized to provide long-tenn corrosion proleclian. Ticback anchors may consisl of hclical anchors. Helical anchors consist of a lead section and sections of exlension bars thal can be added on ro the Icad section. The lead section is made of single or mulliple slecl hclical Il�ghls wclded onlo a square stccl bar.
