Anchored Retaining Walls: How Do Tiebacks Work?
One of America’s most accomplished design-build contractors, Schnabel creates excavation support systems and anchored retaining walls by using tiebacks to provide reliable lateral resisting force.
Secant Pile Wall Construction And Installation
Secant pile walls are constructed by drilling in a series of alternating primary (drilled first) and secondary (drilled second) overlapping shafts to form a continuous secant wall. The concrete in the shafts can be all low-strength, all high-strength, or a combination of low-strength primary and high-strength secondary shafts. Steel piles or reinforcing steel are typically placed in the secondary shafts. Unreinforced high-strength shafts can also be constructed in a self-supporting circular ring, such as those frequently used for access shafts to tunnels.
