What are the Methods and procedures for providing tiebacks?
Various types of restrained wall systems such as tiebacks, screw anchors, dead men anchors, soil nails etc are used to provide the additional stability to cantilever retaining walls. A tieback is basically a structural component installed in rocks or soil to transfer the applied tensile loads into the ground The one end of the tiebacks are secured to the walls, while the other end is anchored to a stable structure. With this arrangement or structural support, tiebacks resists forces that would otherwise cause the walls to lean.
Tiebacks are drilled into the soil using a small diameter shaft and installed at an angle of 15 to 45 degrees. Grouted tiebacks can be constructed as steel rods drilled through a concrete wall out into the soil or bedrock on the other side.
