Installing tiebacks on shoring
NettetCHANCE® helical tiebacks are a pre-engineered mechanical anchoring system for permanent and temporary shoring. The success of the helical anchor tieback system is based on decades of similar use of CHANCE anchors in the electric utility industry. Capacities up to 200,000 pounds per anchor are obtainable with this “instant” tieback …

NettetSoldier pile walls are formed by: 1. Constructing soldier piles at regular intervals (6 ft to 12 ft, typical) 2. Excavating in small stages and installing lagging. 3. Backfilling and compacting the void space behind the lagging. Moment resistance in soldier pile and lagging walls is provided solely by the soldier piles. NettetShotcrete walls can be created by excavating and installing tiebacks (helical or soil nail), followed by shotcrete in several stages. (A method often referred to as “top-down construction”.) This shoring can be …
NettetTieback anchors (also called ground anchors) are pre-stressed structural elements used to transmit an applied tensile load into competent soils. Tiebacks use high strength steel strands or bar that is grouted into a drilled hole with a free stressing (unbonded) length and a bonded length. NettetRaking shoring is meant to keep the walls intact to reduce damage to the existing structure or building. The method consists of a wall plate that is placed vertically along …
