Secant Piles


SECANT PILES 



A nationwide design-build company, Schnabel constructs reliable, structurally
sound secant pile walls that provide effective both excavation support and
groundwater barriers for excavations.

Secant pile walls use very stiff, overlapping shafts that form a continuous
concrete wall. Secant pile shafts are drilled using specialty drills which can
maintain the critical alignment that is required for the secant pile wall to be
effective. The shafts are typically 2 to 4-foot in diameter. Tangent piles are
similar to secant piles except the shafts touch but do not overlap.

With decades of experience providing tailored earth- and water-retention
solutions, Schnabel has the expertise to provide secant walls that help you meet
your most difficult construction goals.

SECANT PILE WALL SOLUTIONS

Secant piles are part of a rigid, robust system that combines earth retention
and groundwater cut-off walls. 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.

Secant pile walls are relatively impermeable and can be used to control the flow
of groundwater into an excavation and limit draw down outside the excavation.
Secant walls are also very stiff and are often used when there are sensitive
structures behind the wall.

An advantage of using secant piles for cutoff wall construction is the ability
of Schnabel’s high torque drill rigs to penetrate hard-drilling conditions while
simultaneously casing the drill hole. These drills can advance a cased hole
through man-made and natural obstructions including cobbles, boulders, and
reinforced concrete.

When difficult drilling conditions are anticipated, secant piles can be a very
economical method for cutoff wall construction. Another benefit is the
relatively low cost of mobilization when compared to other cutoff wall types
such as slurry walls and soil mix walls. To learn more about whether a secant
wall is the right solution for your project, contact one of Schnabel’s eight
regional offices today.


ALWAYS INNOVATING NEW APPROACHES TO BETTER SOLVE OLD PROBLEMS.

RONDOUT WEST BRANCH BYPASS TUNNEL SHAFT

Schnabel installed secant piles in a self-supporting circular ring to support
the construction of a new bypass tunnel to allow water to flow under the Hudson
River to New York City after an older tunnel started to leak.



BARNES-JEWISH HOSPITAL

Schnabel designed and constructed a secant pile wall for the Barnes-Jewish
Hospital Parkview Tower on the Washington University Medical Campus in St.
Louis, Missouri. The perimeter secant wall served as both the permanent
structural basement wall and the temporary earth-retention system for the new
hospital building.




> In 31 years of building deep foundation projects for Schnabel, building a 90’
> deep reinforced circular shaft was one that was very challenging and deeply
> rewarding. Looking forward to working on the next one with our client
> Schiavone.
