Helical Tieback Anchors for Retaining Walls, Shoring & Earth Retention
Ideal Helical Tieback Anchors
Tieback anchors serve as crucial retaining wall anchoring systems designed to provide horizontal reinforcement and stabilization to both permanent and temporary structures that experience lateral loads from soil and water.
Helical tieback anchors are specifically employed in combination with various earth retaining systems, including sheet piles and soldier piles. They are utilized to enhance the lateral resistance of the structure, surpassing the capacity achievable through a cantilevered wall alone. This additional support helps to counteract the forces exerted by the surrounding soil.
The helical design of these tieback anchors allows for a quick and cost-effective installation process. By utilizing helical plates or helices, the anchors can be easily advanced into the soil, providing high load-bearing capacities. Capacities of up to 200,000 lbs. per anchor can be achieved with this efficient helical tieback system.
Maximizing Performance Of Helical Tieback Anchors
The control of torque directly influences the capacity of helical tieback anchors. These anchors can be installed into the retained soil using hydraulic rotary drilling equipment that is readily available.
During installation, the minimum required length of the tieback anchor is achieved. The capacity of the anchor is then determined by measuring the installation torque and correlating it with the holding capacity ratio of the soil strength. This torque reading provides a direct indication of the load-bearing capacity of the anchor.
Once the desired capacity is reached, the helical tiebacks are immediately tensioned and tested, eliminating the need for curing time or cleaning up excavated materials. This process saves a significant amount of time and cost associated with the project. The ability to tension and test the tiebacks immediately after installation allows for efficient progress and ensures that the desired load-bearing capacity is achieved.
